The function models the number of accidents per 50 million miles driven as a function

sesenic [268]

Answer:

x=39, y=180

Step-by-step explanation:

f(x)=0.4x²-31.2x+788.4

For x=39 the graph reaches its lowest point.

The minimum value of y is:

x=39→y=f(39)=0.4(39)²-31.2(39)+788.4

y=f(39)=0.4(1,521)-1,216.8+788.4

y=f(39)=608.4-1,216.8+788.4

y=f(39)=180

Find the area of the triangle given below.

Nimfa-mama [501]

Given:

A triangle with a base length of 22 ft and a height of 20 ft.

To find:

The area of the given triangle.

Solution:

The area of a triangle is obtained by multiplying $\frac{1}{2}$ with its base length and its height.

The area of a triangle $= \frac{1}{2} (b)(h).$

The height is the distance from the base to the highest point on the triangle and the length of the base is the base length.

The given triangle has a base length of 22 ft and a height of 20 ft.

The area of the triangle $= \frac{1}{2} (b)(h) = \frac{1}{2} (22)(20).$

$\frac{1}{2} (22)(20) = \frac{1}{2} (440) = 220$ ft².

The given triangle has an area of 220 ft².
