Thus the surface area of this cylinder involving pie is:
[tex]A=750\pi[/tex] ft²
or
[tex]A\approx 2356.19[/tex] ft²
Step-by-step explanation:
Given
radius = r = 10 ft
height = h = 15 ft
The surface area of a cylinder formula is:
[tex]A=2\pi rh+2\pi r^2[/tex]
substituting the value = r = 10 ft and h = 15 ft
[tex]\:A=\left(2\times \:\pi \:\times \:15\times 10\right)+\left(2\times \pi \:\times \:15^2\right)\:[/tex]
[tex]A=750\pi[/tex] ft²
Thus the surface area of this cylinder involving pie is:
[tex]A=750\pi[/tex] ft²
or
[tex]A\approx 2356.19[/tex] ft²

Which of the following represent an exponential growth function?
Answers
Answer:
[tex]y=3^x[/tex]
Step-by-step explanation:
Exponential Growth Function
The exponential function is often used to model natural growing or decaying processes, where the change is proportional to the actual quantity.
An exponential growth function is expressed as:
[tex]C(t)=C_o\cdot(1+r)^t[/tex]
Where:
C(t) is the actual value of the function at time t
Co is the initial value of C at t=0
r is the (positive) growth rate, expressed in decimal
Since r is positive, 1+r is greater than 1.
From the available options, only the last two of them correspond to exponential functions according to the definition above.
Note the third option has a base of 1/3 which is not greater than 1. In fact, it corresponds to an exponential decay function.
The last option has a base 3 and corresponds to a value of r=2 which correctly fits with the definition presented above, thus the correct choice is
[tex]\mathbf{y=3^x}[/tex]

Which ordered pair is a solution of the equation?
y = -3x-4.
Answers
Answer:
B. Only (-3,5)
Step-by-step explanation:
1. Plug in the x values from the answer choices and see if it gives you the y-value in the answer choices.
A. y=-3(-2) - 4
= 6 - 4
y = 2
The ordered pair for answer A is (-2,4) where the y-value is 4. Well, when you plugged in -2 for x you got 2, not 4. So A can't be the right answer.
B. y=-3(-3) - 4
= 9- 4
y = 5
The y-value in this ordered pair (-3,5) is indeed 5, so this answer holds true.
Therefore, the answer is B because it is the only ordered pair that has the correct solution.

A customer has a credit card that charges 18% simple interest every year. How much interest will the customer save
by paying off a credit card debt of $5,000 at the end of 1 year instead of at the end of 3 years?
Answers
The customer will save interest by paying off a credit debt is $1,800 at the end of 1 year instead of at the end of 3 years
What is simple interest?Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on.
A customer has a credit card that charges 18% simple interest every year.
The customer saves by paying off a credit card debt of $5,000 at the end of 1 year instead of at the end of 3 years.
Interest for three years will be
[tex]\rm A_3 = \dfrac{PRT}{100}\\\\\\A_3= \dfrac{5000*18*3}{100}\\\\\\A_3= 2700[/tex]
Interest for one year will be
[tex]\rm A_1 = \dfrac{PRT}{100}\\\\\\A_1= \dfrac{5000*18*1}{100}\\\\\\A_1= 900[/tex]
The saved amount will be
A = A₃ - A₁
A = 2700 - 900
A = 1800
The customer will save interest by paying off a credit debt is $1,800 at the end of 1 year instead of at the end of 3 years
