start at 2 and go up 1 and over 1/2
The quadratic equation for this would be f(x) = 5x^2 - 10x - 120.
In order to find that, we need to start by taking our x intercept values and setting them equal to zero.
x = 6 ----> subtract 6 from both sides
x - 6 = 0
x = -4 ----> add 4 to both sides
x + 4 = 0
Now that we have both of these zero terms, we can multiply them to get a standard form.
f(x) = (x - 6)(x + 4)
And while this will give us the zeros we need, it will no give us the lead coefficient. So we must multiply by the desired lead coefficient.
f(x) = 5(x - 6)(x + 4)
f(x) = 5(x^2 - 6x + 4x - 24)
f(x) = 5(x^2 - 2x - 24)
f(x) = 5x^2 - 10x - 120
surface area = 2 x pi x r x h + 2 x pi x r^2
2 x (3.14) x 1 x 12 = 75.36
2 x (3.14) x 1^2 = 6.28
75.36+6.28 = 81.64
if you cant use a fraction or decimal, does the answer need to be in terms of pi?
that would be 2 x PI x r x h = 2 x pi x 1 x 12 = 24PI
2 x PI x r^1 = 2 x PI x 1 = 2PI
24 PI x 2 PI = 26 PI
