Using the Pythagorean Theorem, the height of the equilateral triangle is given by:
A. inches.
<h3>What is the Pythagorean Theorem?</h3>
The Pythagorean Theorem relates the length of the legs and of a right triangle with the length of the hypotenuse h, according to the following equation:
For this problem, we have that:
- The height is one side of the triangle.
- The other side is half the length, of 7 in.
- The hypotenuse is the length, of 14 in.
Hence the height is found as follows:
inches.

The cost in dollars is given as 50 + 0.50x, so ...
f(x) = 0.50x +50
B) You want to find x for f(x) = 100. Substitute the given numbers and solve for x.
100 = 0.50x +50
50 = 0.50x
50/0.50 = x
100 = x
You drove 100 miles during the week if the cost was $100.
Answer:
Simplified it is
Step-by-step explanation:
The x-intercepts of a parabola form the factors of the equation. Since the x -intercepts are (-2,0) and (4,0) then the factors are (x+2) and (x-4). Factors are pieces which multiply to make the equation.
This is the standard form of the parabola . Since the y-intercept of the parabola is (0,4) then a number must also be multiplied to it
We find a by plugging in x=0 and y=4.
So the equation is .
