Graph the function using the graphing calculator. find the least positive value of t at which the pendulum is in the center. t = sec to the nearest thousandth, find the position of the pendulum when t = 4.25 sec. d = in.
The least value of the function at which the pendulum is in the center is 0 and the position of the pendulum when t = 4.25 sec. is 4.24
The graph of the functionThe function is given as:
y = 6cos(πt)
See attachment for the graph of the function
The least positive value of tThe value of t is given as: -0.5
From the attached graph, the smallest value of the function when t = -0.5 is 0.
Hence, the least value of the function at which the pendulum is in the center is 0.
The position of the pendulum when t = 4.25 sec.We have:
y = 6cos(πt)
Substitute 4.25 for t

The surface area of the hexagon is 665.11 square centimeters
How to determine the surface area?The question is incomplete, as the diagram is not given.
So, I will calculate the surface area of the hexagon.
The side length of the hexagon is given as:
L = 16 km
The surface area of the hexagon is calculated using:

Kira ran 8 1/5 miles in 69 7/10 minutes. What is Kira’s average time per mile?
Answer:
1 mile = 8.5 minutes
Step-by-step explanation:
Determining the equation:
Kira ran 8 1/5 miles in 69 7/10 minutes.
⇒ Kira = 8 1/5 miles = 69 7/10 minutes
⇒ 41/5 miles = 697/10 minutes
Simplifying both sides:
⇒ 41/5 miles = 697/10 minutes
⇒ 41 miles = 697/2 minutes
Using cross multiplication:
⇒ 41 × 2 miles = 697 minutes
⇒ 82 miles = 697 minutes
Dividing 82 both sides:
⇒ 82 miles = 697 minutes
⇒ 82/82 miles = 697/82 minutes
⇒ 1 mile = 8.5 minutes

5x + 4y = 19.6 --- 1
6x + 5y = 23.8 --- 2
25x + 20y = 98 --- 3
24x + 20y = 95.2 --- 4
3 - 4 : x = 2.8
Sub x = 2.8 into 1
5(2.8) + 4y = 19.6
4y = 5.6
y = 1.4
so 1 plate costs 2.8 dollars and 1 cup costs 1.4 dollars

A cylindrical tank holds about 615.44
cubic inches of helium. The radius of the tank
is 3 1/2 (3 and one half)inches. What is the height of the tank?
Use 3.14 for Pi. (Please give explanation/show work)
Answer:
The height is 15.992 in
Step-by-step explanation:
1. The equation for a cylinder is [tex]V=\pi r^2h[/tex]. In this case, the equation looks like [tex]615.44=\pi (3.5)^2h[/tex]
2. Isolate h by dividing both sides of the equation by [tex]\pi (3.5)^2[/tex]
3. This leaves us with [tex]\frac{615.44}{\pi (3.5)^2}=h[/tex]
4. Solve for the left side, which leaves us with h = 15.992 (rounded to the nearest thousandth)

The volume of a cylinder is 10.14 cudic centimeters. If a cone has the same height and radius as the cylinder, what is its volume?
Answer:
3.38 cm^3
Step-by-step explanation:
volume of cylinder = pi r^2 h
10.14 / pi = r^2 h
volume of a cone = 1/3 pi r^2 h
V = 1/3 pi (10.14/pi) = 3.38

What is Inverse Function?Inverse Function is a function that swaps domain and range.
What are domain and range?Domain is the set of all x-values while Range is the set of all y-values, can be defined in coordinate point as (x,y).
StepsIf (x,y) is an original function then (y,x) will be an inverse function of original.
We are given the function g = {(a,1),(b,2),(2,3),(d,4)} - swap the domain and range.
Therefore, the inverse of function g is [tex]\displaystyle \large{g^{-1}}[/tex] = {(1,a),(2,b),(3,2),(4,d)}

Which of the following number CANNOT represent the probability of an event?
A. 0.888
B. 0
C. 4.2
D. 0.39
Answer:
c
4.2 would mean a 420% chance of something happening which doesnt make sense
The number 4.2 cannot represent the probability of an event because it is greater than one.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
The probability of an event must be less than or equal to one.
So 0.888 can represent the probability of an event because it is a non-negative number that is less than or equal to one.
0, cannot represent the probability of an event because it is a non-negative number but it is not less than or equal to one. This number represents an impossible event.
4.2, cannot represent the probability of an event because is greater than one which means it represents an event that is certain to occur, which is not a probability.
0.39, can represent the probability of an event because it is a non-negative number that is less than or equal to one.
Therefore, the number 4.2 cannot represent the probability of an event because it is greater than one.

General form of an exponential function: [tex]\sf y=ab^x[/tex]
where:
a is the y-intercept (or initial value)b is the base (or growth factor)x is the independent variabley is the dependent variableIf b > 1 then it is an increasing function
If 0 < b < 1 then it is a decreasing function
If the mountain is losing elevation at a rate of 5% every millennium , then it as every millennium passes, it will be 95% of the height it was in the previous millennium (as 100% - 5% = 95%)
Given:

Answer:
5/8 is smaller.
Step-by-step explanation:
A ratio is just a different type of fraction, a 5:8 ratio means 5/8 which is 0.625. A 7:9 ratio equals 7/9 which is 0.777777
Then to compare them you see which is smaller or bigger.
0.77777 is bigger than 0.625 so we know that 0.77777777 which was the 7:9 ratio is the bigger one.

Second one is biggerHow many cups of water should be mixed with 1/4 cup of vinger to make the cleaning solution
Answer:
"mix 1 cup of vinegar with 1 gallon of water"
1 cup = 8oz; 1/4 cup = 2oz
You can see that the amount of vinegar is 1/4 of the original amount,
so, we will need 1/4 of the amount of water, which is 1gallon = 128oz
so, 1/4 times 128oz = 32oz, which is one quart
Algebraically, 8oz : 128oz = 2oz : x
8x = 256; x = 32oz
