Answer:
The height of the roller coaster car is: h = 7.8 m
Step-by-step explanation:
Given
Mass m = 600 kg
Potential Energy P.E = 46,000J
To determine
Height h = ?
Using the formula
P.E = mgh
Here:
m is the massg is the gravitational acceleration (9.8 m/s²)h is the heightso substituting m = 600 kg, P.E = 46,000J, and g = 9.8
P.E = mgh
46000 = 600 × 9.8 × h
h = 46000 / 5880
h = 7.8 m
Therefore, the height of the roller coaster car is: h = 7.8 m

Help, 5 says write the equation you would use to find the measure of each angle
Answer:
x=18, 4x=72, x=90
Step by-step explanation:
180 degrees = 90 degrees + x+ 4x
180 degrees = 90 +5x
180-90=5x
90=5x
x=18 degrees
right angle: 90 degrees
4x= 72 degrees

When multiplying the 2 and the -12 it would be -24, not 24. Which if my mental math is correct, would make the answer 6
Edit:
Note that subtracting a negative is the same as adding the absolute value.
so:
-24-(-30)
changes to
-24+30
and it equals
6

Jada saw a music video that her favorite artist recently posted online. The equation v (t) = 320 ⋅ 4t represents the number of views v of the video, t days since Jada saw the video. What does v (2) equal? (only enter number)
Answer:
2,560
Step-by-step explanation:
The equation v(2) is equal to 2560.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
v(t) = 320 x 4t ________(1)
v(t) represents the number of views v of the video, t days since Jada saw the video.
We see that,
v(t) is a function where t is the input and v(t) is the output.
Now,
Substitute t = 2 in (1)
v(t) = 320 x 4 x 2
= 320 x 8
= 2560
Thus,
The v(2) is equal to 2560.

Use the Rational Zeros Theorem to write a list of all potential rational zeros.
Answer:
1/5,2/5,4/5,1,2,4 B
Step-by-step explanation:
To my recollection the rational zeroes theorem is when you take all the factor of the Y intercept and list those and then take the factors from before and divide it by A
The first step would be to break down 4 into
1,2,4
Those are our first couple of answers, now it's time to divide it by 5
so we have 1/5, 2/5,4/5
