Answer:
62.000124 in. cubed
Step-by-step explanation:
cm to inches: 0.3937007874 to 1
the side edges are 3.937007874
Since it's a square pryramid, all of the side lengths are equal. 3.937007874^2 is 15.500031.
The formula for a pyramid: base*height/3
15.500031*12/3 = 62.000124 in. cubed
A quadratic with roots at 8 and 5 is f(x) = x^2 +12x + 20
In order to find an equation given roots you can create statements that equal 0 in order to create parenthesis. For instance we know x = 8 at one point. So, we can solve that to equal 0.
x = -2 ----> add 2 to both sides
x + 2 = 0
We can do the same for the other zero.
x = -10 ----> add 10 to both sides
x + 10 = 0
Now that we have both of these, we can multiply these two things together. This will give us the function we need.
f(x) = (x + 2)(x + 10)
f(x) = x^2 + 10x + 2x + 20
f(x) = x^2 + 12x + 20
7x1=7, then 4x1/4= 4x1=4 divided by 4= 1. Then subtract 7- 1= 6
