Answer 1

Answer:

[tex]\textsf{1.} \quad a_n=174-6n[/tex]

[tex]\textsf{2.\;a)} \quad A=5000\left(1.019\right)^{4t}[/tex]

   b)  9.25 years (to the nearest quarter)

Step-by-step explanation:

Question 1

[tex]\boxed{\begin{minipage}{8 cm}\underline{General form of an arithmetic sequence}\\\\$a_n=a+(n-1)d$\\\\where:\\\phantom{ww}$\bullet$ $a_n$ is the nth term. \\ \phantom{ww}$\bullet$ $a$ is the first term.\\\phantom{ww}$\bullet$ $d$ is the common difference between terms.\\\phantom{ww}$\bullet$ $n$ is the position of the term.\\\end{minipage}}[/tex]

Given terms of an arithmetic sequence:

[tex]a_{28}=6[/tex][tex]a_{22}=42[/tex]

Substitute the given values into the arithmetic sequence formula to create two equations:

[tex]\implies a_{28}=a+27d=6[/tex]

[tex]\implies a_{22}=a+21d=42[/tex]

Subtract the second equation from the first equation to eliminate a and solve for d:

[tex]\implies 6d=-36[/tex]

[tex]\implies d=-6[/tex]

Substitute the found value of d into one of the equations and solve for a:

[tex]\implies a+27(-6)=6[/tex]

[tex]\implies a-162=6[/tex]

[tex]\implies a=168[/tex]

Substitute the found values of a and d into the formula to create an equation for the nth term of the sequence:

[tex]\implies a_n=168+(n-1)(-6)[/tex]

[tex]\implies a_n=168-6n+6[/tex]

[tex]\implies a_n=174-6n[/tex]

Question 2

[tex]\boxed{\begin{minipage}{8.5 cm}\underline{Compound Interest Formula}\\\\$ A=P\left(1+\frac{r}{n}\right)^{nt}$\\\\where:\\\\ \phantom{ww}$\bullet$ $A =$ final amount \\ \phantom{ww}$\bullet$ $P =$ principal amount \\ \phantom{ww}$\bullet$ $r =$ interest rate (in decimal form) \\ \phantom{ww}$\bullet$ $n =$ number of times interest is applied per year \\ \phantom{ww}$\bullet$ $t =$ time (in years) \\ \end{minipage}}[/tex]

Given values:

P = $5000r = 7.6% = 0.076n = 4 (quarterly)

Substitute the given values into the compound interest formula to create an equation with respect to time, t:

[tex]\implies A=5000\left(1+\dfrac{0.076}{4}\right)^{4t}[/tex]

[tex]\implies A=5000\left(1.019\right)^{4t}[/tex]

To find when the value of the investment will be worth more than $10,000, substitute A = 10000 into the equation:

[tex]\implies 10000 < 5000\left(1.019\right)^{4t}[/tex]

[tex]\implies 2 < \left(1.019\right)^{4t}[/tex]

[tex]\implies \ln 2 < \ln\left(1.019\right)^{4t}[/tex]

[tex]\implies \ln 2 < 4t\ln\left(1.019\right)[/tex]

[tex]\implies \dfrac{\ln 2}{4 \ln\left(1.019\right)} < t[/tex]

[tex]\implies t > 9.20672924...[/tex]

Therefore, the investment will be worth more than $10,000 from 9.25 years (to the nearest quarter).

Answers

The given coordinates are actually a rectangle

How to determine the quadrilateral type?

The coordinates are given as:

A (3, 1), B (1, 5), C (9, 9), and D (11, 5).

Calculate the distance between the coordinates using:

[tex]d = \sqrt{(x_2 -x_1)^2 +(y_2 -y_1)^2[/tex]

So, we have:

[tex]AB = \sqrt{(3 -1)^2 +(1-5)^2} =\sqrt {20[/tex]

[tex]BC = \sqrt{(1 -9)^2 +(5-9)^2} =\sqrt {80[/tex]

[tex]CD = \sqrt{(9 -11)^2 +(9-5)^2} =\sqrt {20[/tex]

[tex]DA = \sqrt{(11 -3)^2 +(5-1)^2} =\sqrt {80[/tex]

The above shows that the opposite sides are congruent

Next, we calculate the slopes using:

m = (y2- y1)/(x2- x1)

So, we have:

AB = (1- 5)/(3-1) = -2

BC = (5- 9)/(1-9) = 1/2

CD = (9- 5)/(9-11) = -2

DA = (5- 1)/(11-3) = 1/2

The slopes of adjacent sides are opposite reciprocals.

This means that the sides are perpendicular

Hence, the given coordinates are actually a rectangle

Step-by-step explanation:

Solving system of linear equation using substitution method:

   3x + y = 9 ---------------(I)

          y = -4x + 10 -----------------(II)

Substitute y = -4x + 10 in equation (I)

What are linear equations?

Linear equations are equations that have constant average rates of change, slope or gradient

How to determine the point of intersection for the pair?

The pair of linear equations is given as:

x + y = 0.7

y = 3x + 11.7

Substitute y = 3x + 11.7 in x + y = 0.7

x + 3x + 11.7 = 0.7

Evaluate the like terms

What is the equation of the line that is parallel to line R, y = 2x + 5, and passes through the
point (-2, 2)?



Answers

Answer:

y = 2x + 6

Step-by-step explanation:

We are given the line R, which is y=2x+5, and we want to find the equation of the line that is parallel to this line, and that also passes through the point (-2, 2).

Parallel lines have the same slope, yet different y-intercepts.

So, we should first find the slope of y=2x+5.

The line is written in slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept.

As 2 is in the place of where m (the slope) should be, 2 is the slope of the line.

It is also the slope of the line parallel to it.

We can write the equation of the new line in slope-intercept form as well; here is the equation so far, with what we know:

y = 2x + b

We need to find b.

As the equation passes through the point (-2, 2), we can use its values to help solve for b.

Substitute -2 as x and 2 as y.

2 = 2(-2) + b

Multiply.

2 = -4 + b

Add 4 to both sides.

6 = b

Substitute 6 as b.

y = 2x + 6

This fraction can be reduced, however, since both 18 and 30 are even numbers and can be divided by at least 2. In simplest form, this fraction can be reduced by 6.

30 divided by 6 equals 5.
18 divided by 6 equals 3.

Math man fell from the top of a 500 meter building. The equation d = t squared * 0.25 describes math man's distance from the ground as he falls. How long does math man spend falling if he falls all the way from the top of the building to the ground? Round your answer to the nearest tenth.

Answers

Based on the equation of the function of the height of the building, it takes the man 44.7 seconds to fall from the top

How to determine how long it takes the math man to fall?

The function of the height where the man falls is a quadratic function, and the equation of the function is given as:

d = t^2 * 0.25

The height of the building is 500

This means that the value of d is 500.

So, we have;

d = 500

Substitute 500 for d in the equation d = t^2 * 0.25

500 = t^2 * 0.25

Divide both sides of the above equation by 0.25

500/0.25 = t^2 * 0.25/0.25

Evaluate the quotient in the above equation

t^2 = 2000

Take the square root of both sides in the above equation

√t^2 = √2000

Evaluate the exponent

t = 44.7

Hence, it takes the man 44.7 seconds to fall

I need to sketch a triangle.

Answers

The exact distance and direction that Patrick is from Johnny is; 177.81 ft and 215.52°

How to utilize trigonometric ratios?

Let the distance of Johnny to Patrick be x.

The angle opposite x would be; (90 - 50) + 90 + 30 = 160°

We will therefore use the cosine rule to find x;

X² = A² + B² - 2ABcosx

Where;

A and B are the distance of Johnny to Rob and Rob to Patrick respectively. Thus;

X² = 130² + 50² - 2(130)(50)cos160

X²= 16900 + 2500 + 12216.004

X² = 31616.004

X = 177.81 ft

To get the direction "y" we will use sine rule;

50/siny = 177.809/sin160

50/siny = 177.809/0.342

50/siny = 519.9094

Siny = 50/519.904

Siny = 0.09617

y = sin⁻¹(0.09617)

Answers

The dimensions of the length and width are 25 meters and 12. 5 meters respectively.

How to determine the values

Area of a rectangle

area of rectangle = l × w

where

l = length

w = width

Note that,

Perimeter = 2w+ l

50 = 2w + l

l = 50  - 2w

Hence,

area = w(50 - 2w)

288 = 50w - 2w²

-2w² + 50w - 288 = 0

-w² + 25w - 144 = 0

The dimension w can be found as follows;

w = - b / 2a

where

a = -1

b = 25

w = - 25 / 2 ×  -1

w = 12.5 meters

Then, we have that

l = 50  - 2w

Substitute the value of w

l = 50 - 2(12.5)

l = 50 - 25

I = 25 meters

Pamela is 9 years younger than Jiri and the sum of their ages is 41 what is jiri's age

Answers

Answer:

Jiri is 25 years old.

Step-by-step explanation:

1)Pamela =Jiri-9 ( Pamela is 9 years younger than Jiri)

2)Pamela +Jiri=41

Substitute equation 1 into equation 2

(J-9)+J= 41

2J-9=41

Add 9 to both sides:

2J=41+9

Divide by 2:

2J=50

J=25

the required Jiri's age is 25 years.

Pamela is 9 years younger than Jiri and the sum of their ages is 41. What is Jiri's age is to be determined.

What is arithmetic?

In mathematics, it deals with numbers of operations according to the statements.

Let the age of Pamela and Jiri is x and y respectively
Pamela is 9 years younger than Jiri. so,
y = x + 9   - - - - (1)
the sum of their ages is 41
x +  y = 41  - - - - (2)

From equation 1 put y in equation 2
x + x + 9 = 41
2x + 9 = 41
2x = 41 - 9
2x = 32
x = 32/2
x = 16
Now put this x =16 in equation 1
y = 16 + 9
y = 25

Thus, the required Jiri age is 25 years

Which statement is true about the function f(x) = 6x7?
The function is even because f(–x) = f(x).
The function is odd because f(–x) = –f(x).
The function is odd because f(–x) = f(x).
The function is even because f(–x) = –f(x).

Answers

Answer: The function is odd because f(–x) = –f(x).

Step-by-step explanation:

[tex]f(x)=6x^7\\\\f(-x)=6(-x)^7 = -6x^7\\\\\therefore f(x)=-f(-x)[/tex]

The function is odd because f(–x) = –f(x).

How to determine the true statement?

The function is given as:

f(x) = 6x^7

A function is odd if the following is true

f(-x) = -f(x)

Calculate f(-x)

f(-x) = 6(-x)^7

f(-x) = -6x^7

Calculate -f(x)

-f(x) = -6x^7

By comparison;

f(-x) = -f(x) = -6x^7

Hence, the function is odd because f(–x) = –f(x).

I am odd I am less than 40 both of my digits are perfect squares t-u=0

Answers

Answer:

19 or 14

Step-by-step explanation:

Since the number is odd you can disqualify all even numbers up to 40 including 0.


Next since this number has 2 digits you can take out all 1 digit numbers.


After that, find perfect squares that also are 1 digit each.


Lastly merge the combination of the numbers as each digit on each sides in such a way that the result is less than 40.
