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
4x(3x + 8) - 7y(5x - 1) =
12x^2 + 32x - 35xy + 7y
Thomas paid $5 for 100 folders, to find cost of each folder:
5/100 = $0.05
Therefore, the cost of each folder was $0.05
Hope I helped :)
Set up a right triangle
The base will be 2,500 feet and the angle where the hypotenuse meets the base will be 4 degrees
The height is your x value,
tan4=x/2,500
Multiply both sides by 2500
2500tan4=x
x=174.817
The answer is B
