(C) (-2, -36) . . . . . . is the appropriate choice
_____
An easy way to tell is to let a graphing calculator show you.
Or, you can rearrange the equation to vertex form.
f(x) = 5(x² +4x) -16
= 5(x² +4x +4) -16 -5*4 . . . . complete the square
= 5(x +2)² -36
So, the vertex is (-2, -36).
Answer:
<h2>C.</h2>
Step-by-step explanation:
ABC is congruent to GEF. The transformation made was reflecting over the origin.

Given:
Amount = 8700
Time = 3 years
Rate of interest = 24% per annum
To find:
The principal values.
Solution:
Formula for amount:

Where, A is amount, P is principal, r is the rate of interest and t is the number of years.
Putting
, we get




Divide both sides by 1.906624.



Therefore, the principal value is about 4563.04.
