Answer:

The triangle's base is 9 inches.

Step-by-step explanation:

The area of a triangle is calculated with the base × perpendicular height × \frac{1}{2}.

We already know the area is 18 square inches and the perpendicular height is 4 inches, so we can calculate the base.

4 × b × \frac{1}{2} = 18

2 × b = 18

b = 18 ÷ 2

b = 9

Write an equation for the given function given the period, phase shift, and vertical shift.
lbvjy [14]

ANSWER

y = \cot(x  -  \frac{\pi}{3} )  + 2

EXPLANATION

The cotangent function that is fully transformed is of the form

y =a  \cot(bx + c)  + d

where 'a' is the amplitude.

\frac{\pi}{b}  = \pi

is the period.

This implies that b=1

The phase shift is

\frac{c}{b}  =  -  \frac{\pi}{3}

Substitute b=1 to get;

c  =  -  \frac{\pi}{3}

and d=2 is the vertical shift.

We choose a=1 to get the required function as

y = \cot(x  -  \frac{\pi}{3} )  + 2

Answer:

D. 18.18

Step-by-step explanation:

Based on the information given we would set up the ratio

\frac{27.5}{25}  =   \frac{20}{x}We then cross multiply to get 20x25=27.5x

multiply

500=27.5x

divide to solve for x

x=18.18

width = 18.18
