Answer:
Surface area of cube = 6x²
surface area of cube = surface area of sphere
it means that 6x²=4πr²
x²=

Answer:
Option 2 - 1 minute
Step-by-step explanation:
Given : Michelle jumps from a plane at an altitude of 1000 m. After 10 seconds her parachute opens. The graph shows the relationship between her altitude and time.
To find : How long does it take for her to be half way between the plane and the ground?
Solution :
Total altitude is 1000 m.
Half of the way between plane and the ground is
Now, Referring the graph given at an altitude of 500 m the line passes at time t=1 min.
Therefore, The time taken to be half way between the plane and the ground is 1 min.
Hence, Option 2 is correct.
Refer the attached figure below.

Option B: 4 is the multiplicative rate of change of the function
Explanation:
The exponential growth function is
We need to determine the multiplicative rate of change of the function.
First, let us determine the values of function.
x y
1 8
2 32
3 128
4 512
Since, the multiplicative rate of change of an exponential function is the number by which the next term is increasing or decreasing.
Thus, the multiplicative rate of change of the function is given by
Multiplicative rate of change of the function =
Multiplicative rate of change of the function =
Multiplicative rate of change of the function =
Thus, the multiplicative rate of change of the function is 4
Therefore, Option B is the correct answer.
