Answer:
f(x) = -4/3x² -2/3x +10
Step-by-step explanation:
The quadratic regression function of a graphing calculator or spreadsheet can determine the equation for you.
___
Or, you can determine it yourself.
The equation can be written in the form ...
f(x) = a(x +3)(x -5/2) . . . . . . . using the given x-intercepts
for some value of "a"
For x = 0, this must match the y-intercept.
f(0) = a(0 +3)(0 -5/2) = 10
-15/2·a = 10
a = -20/15 = -4/3
So, the function can be written as ...
f(x) = (-4/3)(x +3)(x -5/2)
or
f(x) = -4/3x² -2/3x +10
Hi there, just do 15/12*100% and that would equal 125%
Since:
Area of a triangle = 1/2 * base * height
2x^2 ∗ 3xy/2
<span>6x^3y/2 <span>= 3x^3y/1
3x^3y/1
Therefore, the </span></span>expression that represents the area of the triangle is <span>3x^3y/1.
I hope my answer has come to your help. Thank you for posting your question here in Brainly.</span>
Considering the volume of a rectangular prism, it is found that the volume of the wooden mold is given by:
C. 6,000 in³
<h3>What is the volume of a rectangular prism?</h3>
The volume of a rectangular prism of length l, width w and height h is given by:
In this problem, the wooden mold is composed by two rectangular prisms:
- The first has dimensions of 25 in, 10 in and 12 in.
- The second has dimensions of 20 in, 12 in and 12 in.
Hence the volume in cubic inches is given by:
Rounding, it is closest to 6000 in³, hence option C is correct.
