Using a linear function, it is found that:
a. The table is completed as follows: Month 2, Stamps 144; Month 3, Stamps 156; Month 4, Stamps 168; Month 5, Stamps 180.
b. She will have 264 stamps after one year.
c. The function is given by: t(n) = 120 + 12n.
What is a linear function?A linear function, in slope-intercept format, is modeled according to the following rule:
y = mx + b
In which:
m is the slope of the function, which is the rate of change of the function, that is, the change in y divided by the change in x.b is the y-intercept of the function, which is the the value of y when the function crosses the x-axis(x = 0).For the function in this problem, we have that:
The intercept is of 120, as the initial value is of 120 stamps.The slope is of 12, as 12 stamps are added each month to the collection.Hence the function is given by:
t(n) = 120 + 12n.
To complete the table, we find the numeric values are follows:
t = 2, t(2) = 120 + 12(2) = 144.t = 3, t(3) = 120 + 12(3) = 156.t = 4, t(4) = 120 + 12(4) = 168.t = 5, t(5) = 120 + 12(5) = 180.One year from now is 12 months, hence:
t(12) = 120 + 12(12) = 264.

5 mph for 2 hours and 4 mph for 3 hours
4 mph for 2.25 hours and 6 mph for 1.5 hours
gives possible rates and times for two of his jogs
1.Let's determine the relationship between the rate of jogging and the time f jog in each scenario.
First Rate = [tex]\frac{6}{1.5} =4[/tex] time = 1.5 hours
Second Rate = [tex]\frac{5}{1.25} = 4[/tex] time = 1.5 hours
As a result, in this instance, the duration of his runs does not appear to be inversely related to their intensity.
2.First Rate = [tex]\frac{5}{2} =2.25[/tex] time = 2 hours
Second Rate = [tex]\frac{4}{3} =1.33[/tex] time = 3 hours
Therefore, in this instance, the duration of his runs appears to be inversely related to his pace.
3.First Rate = [tex]\frac{4}{2.25}[/tex]=1.77 time = 2.25 hours
Second Rate = [tex]\frac{6.5}{1.5} =4[/tex] time = 1.5 hours
Therefore, in this instance, it appears that the duration of his runs is inversely related to his speed.
4.First Rate = [tex]\frac{4.5}{3}[/tex]=1.5 time = 3 hours

A physics student walks 100 meters in 80 seconds. The student stops for 30 seconds, and then walks 200 meters farther in 90 seconds. What is the average speed of the entire walk?.
The average speed of the student for his entire walk is equal to 1.5 m/s. Therefore, option (b) is correct.
What is the average speed?
The average speed of a body is calculated as the total distance traveled in a fixed interval of time. The average speed can be determined by dividing the total distance traveled by a body by the total time.
The average velocity is a single value if the object moves uniformly. Speed is a scalar quantity, it has no specified direction. The average speed has the S.I. unit the same as velocity i.e. m/s.
Given the distance covered by a student in first 80 sec = 100m
After stooping for 30sec again cover a distance of 200m in 90sec.
The total distance traveled by the student = 100 + 200 = 300m
The time taken by student to cover distance = 80 + 30 +90 = 200 sec
The average speed of the student = total distance/ total time taken
= 300/200 = 1.5 m/s
Therefore, the average speed of the student is equal to 1.5m/s.

The equation that describes the graphed function [tex]f(x) = \frac{1}{x}[/tex] is option A:[tex]y = (x + 2) - 1.[/tex] This is shown in the graph given below, and transformation is translation.
To mathematically derive this equation, start with the original function [tex]f(x) = \frac{1}{x}[/tex].
The given function [tex]f(x) = \frac{1}{x}[/tex] has a reciprocal relationship between x and y.
To perform a horizontal translation 2 units left, substitute (x + 2) for x. This gives:[tex]f(x + 2) = \frac{1}{x + 2}[/tex].
Next, to achieve a vertical translation 1 unit down, subtract 1 from the function.

so that it bounces 42 inches.
9
Height was the tennis ball dropped if it bounces 42 inches is 0.7 inch.
What do you understand by direct proportionality?
If two quantities are directly proportional, it means that when one quantity increases at a certain rate, the other quantity also increases at the same rate up to a constant value. It is represented by the proportional symbol ∝.
Let the height of the ball bounces be h
The height of the ball drobbed from be y
It is given that the height that a ball bounces varies directly as the height from which it was dropped.
⇒ h ∝ y
⇒ h = ky where k is the constant of proportionality.
It is given that a tennis ball dropped from 14 inches.
⇒ y = 14 inches
Tennis ball bounces back to 8.4 inches.
⇒ h = 8.4 inches
⇒ 8.4 = k × 14
⇒ k = 8.4/14 = 0.6
Now, tennis ball dropped from 42 inches
y = 42
⇒ h = 42 × 0.6 = 0.7
Therefore, height was the tennis ball dropped if it bounces
42 inches is 0.7 inch.

Determine the total surface area of the composite shape below
Answer:
118.558 cm^2
Step-by-step explanation:
Ok, a rectangular cube and a Cylinder.
Let's start with the rectangular cube.
SA= 2(lw + lh + wh)
total surface area = 94 cm^2
Now the Surface Area of the of the Cone.
A=2πrh+2πr^2
A=2πrh+2πr^2=2·π·1·5+2·π·1^2≈37.69911 cm^2
Since the cone is standing on top of the rectangular cube, we need to deduct just the area of the circle.
A=πr2=π·12≈3.14159 cm^2
So, 84 cm^2 + 37.69911 cm^2 - 3.14159 cm^2
Sum the quantities:
84 cm^2 + 37.6991 cm^2 - 3.14159 cm^2

Andrea is buying some new shirts and sweaters. She is able to buy 5 shirts and 3
sweaters for $89 or she is able to buy 9 shirts and 8 sweaters for $207. How much
does a shirt cost? How much does a sweater cost?
Answer: Shirt = $7 and Sweater = $18
Step-by-step explanation:
5 Shirts, 3 sweaters = $89 (1)
9 Shirts, 8 sweaters = $207 (2)
1 Shirt = $?
1 Sweater = $?
Shirts = x
sweaters = y
(1) -> 5x + 3y = 89
(2) -> 9x + 8y = 207
(1) * 8 = 40x + 24y = $712
(2) * 3 = 27x + 24y = $621
(1) single out 24y -> 24y = $712 - 40x
put value of 24 y into (2)
(2) -> 27x + $712 - 40x = $621
Now solve
-13x = $-91
remove negative -> 13x = $91
x = $7
So a shirt is $7
And we can put $7 into (1) at the start -> 5(7) + 3(y) = $89
35 + 3y = $89
3y = $54
y = $18
Hence x = $7 and y = $18
So Shirt = $7 and Sweater = $18

Based on the amount earned by Justin per hour, and the overtime work rate, Justin's gross pay for the week is $764.50
How to find the gross pay?First, find the amount that Justin earns from Rite Aid Pharmacy for his regular work:
