What is the midpoint of the segment shown below?
kolbaska11 [484]

The midpoint of the segment is (-15/2, -15/2)

<h3>How to determine the midpoint?</h3>

The complete question is in the attached image

The points are given as:

(-8, -7) and (-7, -8)

The midpoint is calculated as:

(x,y) = 1/2 * (x1 + x2, y1 + y2)

So, we have:

(x,y) = 1/2 * (-8 - 7, -7 - 8)

Evaluate the difference

(x,y) = 1/2 * (-15, -15)

Evaluate the product

(x,y) = (-15/2, -15/2)

Hence, the midpoint of the segment is (-15/2, -15/2)

Please help me that’s would be great and I promise to mark brainlest!!

Option A is correct.

If we evaluate the function at x=0, i.e. at the beginning, we have

f(0)=75 \cdot 2^0 = 75 \cdot 1 = 75

with each minute, you multiply the current number of cell by 2, so they double every minute.

Option B is incorrect, because if the number of cells increases by 2 every minute, the function would be

f(x) = 75 + 2k

Option C is incorrect, because after one minute (i.e. when x=1) we have

f(1) = 75\cdot 2^1 = 75 \cdot 2 = 150

cells, so 75 is not the number of cells after one minute

Option D is incorrect in both the initial value and the behaviour of the function
