Answer:
The vertex form parabola y = 2( x+4)² -37
Step-by-step explanation:
<u>Step(i):-</u>
Given parabola equation j(x) = 2x² + 8x -5
Let y = 2x² + 8x -5
⇒ y = 2(x² + 2(4x)+(4)²-(4)²) -5
By using (a + b)² = a² +2ab +b²
y = 2(x+4)²- 32 -5
y = 2 ( x-(-4))² -37
<u><em>Step(ii):-</em></u>
The vertex form parabola y = a( x-h)² +k
The vertex form parabola y = 2(x+4)² -37
Answer:
this question is not complete. need another equation
Step-by-step explanation:
give another equation then I can solve

Answer: 181.25
Step-by-step explanation:
So 4 to 5 is a ratio. Now there is 145 girls, so you figure out 4 multiplied by what is equal to 145. You get 36.25, so you multiply the number 5 by the same number to get your answer. 36.25*5=181.25
