The acceleration, a, in meters per second squared (m/s) due to gravity is O at the Earth's center. It reaches a maximum of 9.8 m/s' at the surface of the earth approximately 4 thousand
miles (mi) from the Earth's center. If d represents the distance from the Earth's center in
thousands of miles, which of the following graphs in the da-plane could represent this
relationship?

hi there!

the answer will be d: 2

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
