Answer:
254.34 miles²
Step-by-step explanation:
How do we find the area of a circle?
The area of a circle can be found using πr², where r = radius. We have the radius as 9 miles, and pi is shortened to 3.14.Solving
[tex]3.14*9^2[/tex] [tex]3.14*81[/tex][tex]254.34[/tex]Therefore, the area is 254.34 miles².
Have a lovely rest of your day/night, and good luck with your assignments! ♡
Answer:
Formula for area of a circle:
πr^2,
where pi is equal to 22/7 or 3.14
and r is the radius that is being squared
Plug in the actual values to this formula to find the area;
a = πr^2
a = 3.14 x 9^2
a = 3.14 x 81
a = 254.34, your answer is 254.34 square miles.

Answer:
C
Step-by-step explanation:
The reason it is C is mainly because it is the only line with a negative slope. A negative slope this direct \. It is not A because that is a positive slope (/). It is not B because that line is undefined which means it would look like this x = 2. And D is wrong because that is a zero slope line which looks like this y = 5. So it is C.

Suppose an exponential function can be written in the form y=ab^x, and we know the common ratio b and some point (ℎ,k). True or false: The function can also be written as y=k·b^x-h.
Answer:
true
Step-by-step explanation:
y = ab^x
the coordinates of the point are x and y values.
so, we can express "a" by these values :
k = ab^h
a = k/(b^h) = k × b^-h
now we use this identity in the original equation and get
y = k × b^-h × b^x = k×b^(x-h)
and that is exactly the same as the proposed form.

(x - 1) hours? Express your answer as a polynomial.
(4x+5) miles..........1 hour
x miles .........(x-1) hour
(4x+5) * (x-1) = 1 * x

When evaluating (6 x + 9) squared minus 5 for x = 1, the given value of 1 is substituted for what part of the expression?
the exponent
the constant
the variable
any numerical value
Answer:
the variable
Step-by-step explanation:
Given expression:
[tex](6x+9)^2-5[/tex]
When evaluating the expression for [tex]x=1[/tex], we need substitute 1 for the variable ([tex]x[/tex]) in the expression.
Evaluating the expression for [tex]x=1[/tex]:
[tex]\implies (6\cdot1+9)^2-5[/tex]
[tex]\implies (6+9)^2-5[/tex]
[tex]\implies (15)^2-5[/tex]
[tex]\implies 225-5[/tex]
[tex]\implies 220[/tex]
Answer:
Variable
As variable is x and we have to substitute x=1Step-by-step explanation:
Let's find the value
[tex]\\ \rm\Rrightarrow (6x+9)^2-5[/tex]

Which line has an undefined slope?
y = x-5
3y - 6x = 0
x= 10
y = -5
Answer:
x = 10
Step-by-step explanation:
Y = x-5 has a slope of 1
3y - 6x = 0 is a clear linear equation with a Y-intercept of 0
y = -5 has no slope
x = 10 is a line going straight up and intersects the point (10, 0)
Which is an undefined slope

What is below the question is what I mean.
What do you call the point where a perpendicular bisector crosses another line?
Answer:
If AB crosses at a right angle, it is called the "perpendicular bisector" of PQ. If it crosses at any other angle it is simply called a bisector. Drag the points A or B and see both types. For obvious reasons, the point F is called the midpoint of the line PQ. See also Angle bisector.

CS = x, and since AB = BC = CD = DA = 1cm -> SD = 1 - x
We see that angle DSP = angle APQ (because they simultaneously equal to 90 when added angle DPS)
So, triangle DSP = triangle APQ (equal hypotenuse - square side and equal angle.)
Similarly, we can prove triangle SCE and QBE in the same way
So, all 4 of the triangles are equal to each other.
-> SD = CE = BQ = AP = 1-x
Calculate the area of 4 triangles : [ x(1-x) : 2 ] x 4 = x(1-x) x 2
Area (PQRS) = 1 - [ x(1-x)] x 2 = 1 - 2x + 2x(squared) = [tex]2x^{2} -2x + 1[/tex]
ii) Half area of PQRS = [tex]x^{2} -x+1[/tex]
= [tex]x^{2} -\frac{1}{2} x-\frac{1}{2} x + \frac{1}{2} = x(x-\frac{1}{2} )- \frac{1}{2}(x-\frac{1}{2} ) + \frac{1}{4} = (x-\frac{1}{2})^{2} + \frac{1}{4}[/tex]
We have : [tex](x-\frac{1}{2}) ^{2}[/tex]
has the smallest value of 0 -> The smallest half value of PQRS = 1/4 -> The smallest value of PQRS = 1/2

Answer:
x=-3
Step-by-step explanation:
there are three x's and five one's so the equation is 3x+5
on the other side there are 2 negative x's and 10 negative one's so the equation is -2x-10
set them equal to each other
3x+5=-2x-10
5x=-15
x=-3

Answer:
a) 4x
b) 2 + 4y
Step-by-step explanation:
a) 7x - 6x + 3x
To do this, we just need to collect the terms together. They are all coefficients of x, so all we need to do is add the number together.
7 - 6 + 3 = 4
7x - 6x + 3x = 4x
b) 2(1 + 2y)
Here we need to expand the brackets. 2 is shown to be multiplied by 1 +2y:
2(1 + 2y)
= 2*1 + 2*2y
= 2 + 4y
I hope this helps :)

Which point would not be a solution to the system of linear inequalities shown below?
Answer:
The coordinates (12,7) would NOT be a solution to the system of linear inequalities shown below.
Step-by-step explanation:
If you do the graphing and you look at all your options of coordinates, (12,7) is the only one that is not in the shaded areas or in the lines of the inequalities. Therefore, (12,7) should be the answer to that question. :)

Which fruit has the lowest unit price?
A.
2.5 pounds of grapes for $4.19
B.
4 pounds of apples for $5.49
C.
5 pounds of oranges for $6.99
D.
6.5 pounds of strawberries for $9.59
Answer:
A unit is a measure of ratio between two quantities. In this instance, the unit is a pound. The ratio you need to take is the price of each fruit and divide it by the number of pounds each fruit has to get a price per pound. See below for solution.
Step-by-step explanation:
A. 4.19 dollars / 2.5 pounds = 1.676 dollars / pound
B. 5.49 dollars / 4 pounds = 1.3725 dollars / pound
C. 6.99 dollars / 5 pounds = 1.398 dollars / pound
D. 9.59 dollars / 6.5 pounds = 1.475 dollars / pound
The lowest is B, the apples.

You earn $1500 a month and 1/4 of your money goes to pay rent. What expression represents the money you have after you pay rent?
Answer:
x-375
Step-by-step explanation:
First, we find a fourth of $1500.
1/4*1500=375
Then we know that you need to pay $375. We will represent the money right before you pay as x, or any variable you choose.
= x-375

Answer:
{7, 5, 2, 0}
Step-by-step explanation:
The domain is essentially all the [tex]x[/tex] values of the function, where the range is the value of [tex]h(x)[/tex].
So in order to solve this we simply plug in each number into the equation and get:
[tex]h(x)=|-2-5| = |-7|=7[/tex]
[tex]h(x)=|0-5| = |-5|=5[/tex]
[tex]h(x)=|3-5| = |-2|=2[/tex]
[tex]h(x)=|5-5|=|0|=0[/tex]
Therefore the range is: {7, 5, 2, 0}

Answer:
Domain: (-∞, -5) (-1, ∞)
Step-by-step explanation:
Note:
For f(x) > 0: See the points of x for which the graph of f(x) lies above the x-axis.
For f(x) < 0: See the points of x for which the graph of f(x) lies below the x-axis.
We need to find the domain of f(x) for which f(x) < 0
From the graph, we can tell:
f(x) < 0 on (-∞, -5) ∪ (-1, ∞)
Therefore: The domain on which the given graph f(x) is negative, is (-∞, -5) ∪ (-1, ∞)
