Using the digits 9, 8, 7, 6, 5, 4, 3, 2, and 1 in that order to create 100 by using the mathematical operations, (9 + 8 + 7) x (6 - 5) x (4 + 3 + 2) - 1 = 100
It is not possible to create 100 using the digits 9, 8, 7, 6, 5, 4, 3, 2, and 1 in that order without using any mathematical operations.
However, it is possible to create 100 by using mathematical operations like addition, subtraction, multiplication, division, and parentheses. One possible way to do this is:
(9 + 8 + 7) x (6 - 5) x (4 + 3 + 2) - 1 = 100
Here, we first add the first three digits (9 + 8 + 7 = 24), subtract the fourth and fifth digits (6 - 5 = 1), add the next three digits (4 + 3 + 2 = 9), and finally multiply all three results and subtract the last digit (24 x 1 x 9 - 1 = 215 - 1 = 100).
So, using this sequence of digits and mathematical operations, we can create 100.

a college student takes the same number of credits each semester. before beginning college, the student had some credits earned while in high school. after 2 semesters, the student had 45 credits, and after 5 semesters, the student had 90 credits. if c(t) is the number of credits after t semesters, write the equation that correctly represents this situation.
The equation that correctly represents this situation is c(t) = 45 + 45(t-2). This equation states that the total number of credits the student will have after t semesters is equal to 45 (the number of credits they had before beginning college) plus 45 times the number of semesters after two (t-2).
To explain this equation in more detail, we need to break it down. First, the student had some credits earned while in high school, so the equation starts off with c(t) = 45, which is the number of credits the student had before beginning college.
Next, 45(t-2) represents the number of credits earned in the additional semesters since college began. The t-2 part of the equation means that the total number of credits earned in the additional semesters starts at zero for t = 2. Then, for each additional semester, 45 credits are added. So, for example, when t = 5, 45 credits are added to the initial 45 credits the student had before beginning college, resulting in 90 credits.Therefore, the equation c(t) = 45 + 45(t-2) correctly represents this situation.

the amount of bacteria present in a medium after t hours is given by a (t )equals 16 e to the power of 0.32 t end exponent. at what rate is the amount of bacteria changing after 12 hours?
The rate at which the amount of bacteria is changing after 12 hours is 21.698 units/hour.
What is the rate at which the amount of bacteria changing after 12 hours?The given formula for the amount of bacteria present in a medium after t hours is:
[tex]a(t) = 16e^ (0.32t)[/tex]
Now, we need to find out at what rate the amount of bacteria is changing after 12 hours.
This means we need to find out the derivative of a(t) with respect to t and then substitute t = 12 in the derivative formula to get the rate of change of bacteria after 12 hours.
Differentiating the given formula for a(t) with respect to t, we get:
a'(t) = [tex]16(0.32)e^(0.32t)[/tex]
On substituting, t = 12, we get
a'(12) = [tex]16(0.32)e^ (0.32X12)[/tex]
On solving this, we get a'(12) = 21.698.
Therefore, the rate at which the amount of bacteria is changing after 12 hours is 21.698 units/hour.

The cost price of a book is Rs 20 . It is sold at 10% profit. Find its sale price
Answer:
Cost price (CP) = Rs20
% Profit = 10%
Selling price (SP) = y
By formula:
% Profit = (Profit/CP) x 100%
But Profit= SP - CP
Therefore;
% Profit = [(SP-CP)/C.P)] x 100%
Substituting, we have:
10% = [(y-20)/20] x 100%
10/100 = (y-20)/20
1/10 = (y-20)/20
1 = (y-20)/2
Cross multiply
y - 20 = 2
y = 2 + 20
y = 22
Therefore, the Sale price is Rs 22

B. g(x)=6x^2+3 on 0≤x≤4
D. f(x) = (e^x)/x for 2 ≤ x ≤ 16.
Step 1: State the Extreme Value Theorem
The Extreme Value Theorem states that if a function is continuous on a closed interval [a,b], then the function must have a maximum and a minimum on the interval.
Step 2: Check for continuity and closed interval for each function
A. f(x) = 1/x on −10 ≤ x ≤ 10
The function f(x) = 1/x is continuous on the interval (-10, 0) and (0, 10).
However, since the interval given is [−10, 10], we see that the function is not continuous over the closed interval.
Hence the function does not satisfy the hypotheses of the Extreme Value Theorem.
B. g(x) = 6x^2+3 on 0 ≤ x ≤ 4
The function g(x) is continuous on the interval [0, 4].
Therefore, this function satisfies the hypotheses of the Extreme Value Theorem on the given interval.
C. k(x) = {3x^2+9 for 0 ≤ x < 2, 12x for 2 ≤ x ≤ 10} on 0 ≤ x ≤ 10
The function k(x) is continuous on the interval [0, 2) and (2, 10]. H
However, since the interval given is [0, 10], we see that the function is not continuous over the closed interval.
Hence the function does not satisfy the hypotheses of the Extreme Value Theorem.
D. h(x) = (e^x)/x for 2 ≤ x ≤ 16The function h(x) is continuous on the interval [2, 16].
Therefore, this function satisfies the hypotheses of the Extreme Value Theorem on the given interval.
E. m(x) = 6x^3+x+1 on −4 < x < 3
The function m(x) is continuous on the interval (-4, 3).
However, since the interval given is [-4, ∞), we see that the function is not continuous over the closed interval.
Hence the function does not satisfy the hypotheses of the Extreme Value Theorem.
Therefore, the only function that satisfies the hypotheses of the Extreme Value Theorem on the given interval is given by

a) Graph this system of inequalities, we can plot the lines x = 0, y = 0, x = 260, y = 320, and x + y = 380
b) The maximum profit of $5200 achieved.
Define the term selling profit?Selling profit is the profit that a business makes on the sale of its products or services. It is the difference between the selling price and the cost of product.
a) Let x be the number of boards of mahogany sold and y be the number of boards of black walnut sold. Then, the constraints of the problem can be represented by the following system of inequalities:
x ≥ 0 (non-negative constraint)
y ≥ 0 (non-negative constraint)
x ≤ 260 (maximum number of mahogany boards available)
y ≤ 320 (maximum number of black walnut boards available)
x + y ≤ 380 (maximum number of boards that can be sold)
To graph this system of inequalities, we can plot the lines x = 0, y = 0, x = 260, y = 320, and x + y = 380 on a coordinate plane and shade the feasible region that satisfies all of the constraints. The feasible region is the area that is bounded by these lines and includes the origin (0, 0).
b) The profit function P(x, y) can be defined as follows:
P(x, y) = 20x + 6y
To maximize the profit, we need to find the values of x and y that satisfy all of the constraints and maximize the profit function P(x, y).
One way to do this is to use the corner-point method. We can evaluate the profit function at each of the corners of the feasible region and find the corner that gives the maximum profit.
The corners of the feasible region are (0, 0), (0, 320), (260, 0), and (120, 260).
P(0, 0) = 0
P(0, 320) = 6(320) = 1920
P(260, 0) = 20(260) = 5200
P(120, 260) = 20(120) + 6(260) = 4720
Therefore, the maximum profit of $5200 can be achieved by selling 260 boards of mahogany and 0 boards of black walnut.

Why is there an interest?The cost of borrowing money is called interest, and it is typically stated as a percent, such as an annualized rate (APR). By utilizing the money, debtors may accrue interest to lenders, or lenders may pay the interest to borrowers.
We will use annuity formula, which is: [tex]P=C(\frac{1-(1+r)^{-n} }{r} )[/tex]
[tex]P[/tex] is [tex]105,000[/tex]
[tex]C[/tex] is what we need
[tex]r[/tex] is the [tex]0.045/12 = 0.00375[/tex]

[tex]1.5,000=C[197.3612][/tex]
[tex]C=532.02[/tex]
So monthly payment would be around [tex]532.02[/tex]

Therefore, the total number of ways to select 2 cooked and 3 uncooked eggs is 210 ways.
What is combination?In mathematics, a combination is a way of selecting items from a collection, such that (unlike permutations) the order of selection does not matter. In other words, a combination is a selection of items from a larger set, without regard to the order in which they are chosen. The number of combinations of size r that can be chosen from a set of n elements is denoted by the symbol C(n, r), and is given by the formula:
C(n, r) = n! / (r! * (n-r)!)
where n! (pronounced "n factorial") is the product of all positive integers up to n, and r! is the product of all positive integers up to r.
Here,
a) To find the number of ways to select 2 cooked or 3 uncooked eggs, we need to use the combination formula, which is:
ⁿCₓ= n! / r!(n-r)!
where n is the total number of eggs, r is the number of eggs we want to select, and ! represents factorial.
For 2 cooked eggs, we can select them in:
⁷C₂ = 7! / 2!(7-2)! = 21 ways
For 3 uncooked eggs, we can select them in:
⁵C₃ = 5! / 3!(5-3)! = 10 ways
Therefore, the total number of ways to select 2 cooked or 3 uncooked eggs is:
21 + 10 = 31 ways
b) To find the number of ways to select 2 cooked and 3 uncooked eggs, we need to use the product rule of counting. That is, we need to multiply the number of ways to select 2 cooked eggs and 3 uncooked eggs.
The number of ways to select 2 cooked eggs is:
⁷C₂ = 21 ways
The number of ways to select 3 uncooked eggs is:⁵C₃ = 10 ways
Therefore, the total number of ways to select 2 cooked and 3 uncooked eggs is:
21 x 10 = 210 ways

The number of elements (possibly infinite) is called the length of the array. Unlike sets, the same element can appear multiple times at different positions in the sequence, and unlike sets, order matters. Formally, a sequence can be defined in terms of the natural numbers (positions of elements in the sequence) and the elements at each position. The concept of series can be generalized as a family of indices, defined in terms of any set of indices.

Settling Time: Ts=4.4/ζωn
Peak Overshoot: Mp=e^(-ζπ/√1-ζ^2)
Given that the damping ratio is 0.5 and the system is subjected to a step input of 1V, we can determine the rise time, settling time, and peak overshoot.
Rise Time: Tr=4.6/ωn=4.6/2=2.3s
Settling Time: Ts=4.4/0.5ωn=4.4/1=4.4s
Peak Overshoot: Mp=e^(-0.5π/√1-0.5^2)=0.26

Talia has a daily budget of $94 for a car rental. Write and solve an inequality to find the greatest distance Talia can drive each day while staying with her budget. $30 per day plus $0. 20 per mile
The most distance Talia can go each day while staying within her budget is 320 miles.
In this case, our goal is to write an inequality before moving on to solve it.
We begin with the daily rental fee and the cost per mile.
This is stated as $30 per day and $0.20 per mile in the question.
She is required to spend a total of $94.
This means that the total cost of the rental automobile and the cost per mile must be $94 or less.
Let m be the maximum number of miles she can travel.
Hence, we may write the inequality as follows: 30 + 0.2 m 94.
This inequality is what we can now solve;
0.2m ≤ 94 - 30
0.2m ≤ 64
m ≤ 64/0.2
320 miles = m
The most distance Talia can go each day while staying within her budget is 320 miles.

The new coordinates of the two points after rotating the parallel lines 180 degrees clockwise are (2, -7) and (-8, 5).
What are parallel lines?
In geometry, parallel lines can be defined as two lines in the same plane that are at equal distance from each other and never meet.
If the set of parallel lines contains the points (-2, 7) and (8, -5), then the two lines are parallel to each other and have the same slope. We can find the slope of the line that passes through these two points using the slope formula:
slope = (y2 - y1) / (x2 - x1)
slope = (-5 - 7) / (8 - (-2))
slope = -12 / 10
slope = -6 / 5
So, the equations of the two parallel lines are:
y - 7 = (-6 / 5)(x + 2) --- equation 1
y + 5 = (-6 / 5)(x - 8) --- equation 2
To rotate the lines 180 degrees clockwise, we need to negate both the x and y coordinates of the points on the lines. That is, we need to replace each point (x, y) with the point (-x, -y).
So, after the rotation, the new coordinates of the two points will be:
(-(-2), -7) = (2, -7) --- for point (-2, 7)
(-(8), -(-5)) = (-8, 5) --- for point (8, -5)

Determine the length of the missing side of the given triangle. Round to the nearest tenth.
The hypotenuse is 7.7
The leg is 3.4
Answer:
6.9 or 7.0 .
Step-by-step explanation:
*Note that ^2 means raised to the power of two or squared
a^2 + b^2 = c^2
The hypotenuse is always the C, and the leg can be either a or b.
Fill in the blanks with the numbers that we have:
Hypotenuse: 7.7 | Leg: 3.4
3.4^2 + b^2 = 7.7^2
Square the numbers given
3.4 x 3.4 = 11.56
7.7 x 7.7 = 59.29, which leads us to:
11.56 + b^2 = 59.29
To find what b equals, we need to subtract 11.56 from 59.29
59.29 - 11.56 = 47.73
b^2 = 47.73
We need to take the square root of 47.73 to find b. b and b^2 are two different things.
The square root of 47.73 is about 6.90869017977. It asks for the answer to be rounded to the nearest tenth, giving us 6.9 or 7.0.
A rectangle has length 64mm and 37mm each correct to the nearest millimetre.
(a) Write down the lower bound for the length.
(b) Calculate the lower bound for the perimeter of the rectangle.
Step-by-step explanation:
(a) To find the lower bound for the length of the rectangle, we need to subtract half of the smallest unit of measurement from the given measurement.
The smallest unit of measurement given is 1 mm, so half of that is 0.5 mm.
Therefore, the lower bound for the length of the rectangle is:
64 mm - 0.5 mm = 63.5 mm
(b) The perimeter of a rectangle is calculated by adding up the length of all four sides.
The lower bounds for the length and width of the rectangle are 63.5 mm and 36.5 mm, respectively.
So, the lower bound for the perimeter is:
2(63.5 mm + 36.5 mm) = 2(100 mm) = 200 mm

Express each of the following without using decimals: Rs 5. 25
Rs 5.25 can be expressed without decimals as Rs 525/100 or as 5 1/4 (or 5 ¼) using mixed numbers. Both methods allow us to represent the value of Rs 5.25 accurately without using decimal notation.
To express Rs 5.25 without using decimals, we need to convert it into a fraction with a numerator and a denominator. One way to do this is by multiplying both the numerator and the denominator by 100 to eliminate the decimal point.
So, Rs 5.25 can be written as Rs 525/100. This is also known as a fraction in its simplest form, as both the numerator and denominator have no common factors other than 1.
Another way to express Rs 5.25 without decimals is to use mixed numbers. A mixed number is a whole number combined with a fraction. To convert a decimal to a mixed number, we need to find the whole number part and the fraction part.
To find the whole number part, we can simply drop the decimal point and write the digits to the left of it. In this case, the whole number part is 5.
To find the fraction part, we need to subtract the whole number part from the original number and simplify the fraction. In this case, Rs 5.25 can be written as 5 and 1/4 (or 5 ¼), where the fraction part is 1/4.
In conclusion, Rs 5.25 can be expressed without decimals as Rs 525/100 or as 5 1/4 (or 5 ¼) using mixed numbers. Both methods allow us to represent the value of Rs 5.25 accurately without using decimal notation.

Use the line segment that connects ______ and _______ to estimate the vine length after 4 days.
After 4 days, the vine length is about ______.
The top is a chart Please help me!!!
Use the line segment that connects (3, 42.5) and (5, 44) to estimate the vine length after 4 days.
How to determine the lengths after 4 daysGiven the table of values
To do this, we make use of linear interpolation
Such that the points closest to day 4 are (3, 42.5) and (5, 44)
The slope of the line passing through the two points can be found using the formula:
m = (y2 - y1) / (x2 - x1)
where (x1, y1) = (3, 42.5) and (x2, y2) = (5, 44).
Thus, we have:
m = (44 - 42.5) / (5 - 3) = 0.75
So, we have
y = 0.75x + b
Using the point (3, 42.5), we get:
42.5 = 0.75(3) + b
Solving for b, we get:
b = 42.5 - 0.75(3)
b = 40.25
So, the equation is
y = 0.75x + 40.25
To estimate the vine length after 4 days, we substitute x = 4 into the equation and solve for y:
y = 0.75 * 4 + 40.25
y = 43.25
Therefore, the vine length after 4 days is estimated to be about 43.25 units.

The set of all possible y-values for the function h constitutes its range. The range is therefore [-3, 0].
what is range ?The collection of all feasible output values (dependent variable) of a function is known as the range in mathematics. It is the totality of all possible numbers that the function can accept as input (an independent variable) and output. On the number line, the range is frequently represented by an interval or group of intervals. For instance, the range can be written as [-3, 3] if the domain of a function f(x) is [-2, 2] and its output numbers fall within [-3, 3].
