Tanzania [10]
15^15. Answer is 15 to the 15th power because by laws of exponents when you have a base with power m over same base with power n it is base to the m-n power. Simply you subtract the exponents when dividing with same base.

9. Find the coordinates of point C along line segment AE with A(-2,-4) and
Nana76 [90]

Answer:

C = (4,-1)

Step-by-step explanation:

Given

A = (-2,-4)

E = (8,1)

AC:CE = 3:2

Required

Determine the coordinates of C

This is calculated as follows;

C = (\frac{mx_2 + nx_1}{m+n},\frac{my_2 + ny_1}{m+n})

Where:

(x_1,y_1) = (-2,-4)

(x_2,y_2) = (8,1)

m:n = 3:2

So, we have:

C = (\frac{3 * 8 + 2 * -2}{3+2},\frac{3 * 1 + 2 * -4}{3+2})

C = (\frac{24 -4}{5},\frac{3-8}{5})

C = (\frac{20}{5},\frac{-5}{5})

C = (4,-1)
