Answer:
100 inches
Step-by-step explanation:
what times what gives you 1000
100 times 10 = 1000
10 times 100 = 1000
so pick one
The equation of the quadratic function f whose graph is shown below is x² + 6.1x + 8.2
Find the diagram attached.
First, we need to get the zeros of the required function. The point where the curve cuts the x-axis is the zeros.
According to the graph, the curve cuts the x-axis at x = -2 and x = -4.1
The required factors will be (x+2) and (x+4.1)
Taking the product of the factors
f(x) = (x+2)(x+4.1)
f(x) = x²+4.1x+2x +8.2
f(x) = x² + 6.1x + 8.2
Hence the equation of the quadratic function f whose graph is shown below is x² + 6.1x + 8.2

Given:
2x² + 8x - 12 = 0
Solution:
The first term 2x² can't be changed to a complete square form. If we want to change it to the complete square form, we need to change 2x² to 4x². So, multiply both sides of the equation by 2
2x² + 8x - 12 = 0
------------------------- multiplied by 2
4x² + 16x - 24 = 0
then change it to complete quadratic form by adding 16 to both sides
4x² + 16x - 24 = 0
4x² + 16x + 16 - 24 = 16
4x² + 16x + 16 = 16 + 24
4x² + 16x + 16 = 40
(2x + 4)(2x + 4) = 40
(2x + 4)² = 40
This is the complete quadratic form of the equation.
Because there is no option of the solution, we can modify the equation by multiplying the two sides by a square number. I multiply the equation by 4.
(2x + 4)² = 40
4 (2x + 4)² = 4 × 40
4 (2x + 4)² = 160
4 (2x + 4)(2x + 4) = 160
2(2x + 4) 2(2x + 4) = 160
(4x + 8)(4x + 8) = 160
(4x + 8)² = 160
The answer is option b
