The recommended angle for a wheelchair ramp is 5 degrees. If the rise of the ramp to go up the steps is 5 feet, find the horizon
dybincka [34]

Answer:

57.2\ ft

Step-by-step explanation:

we know that

The formula of slope is "rise over run", where the "rise" (means change in y, up or down) and the "run" (means change in x, left or right)

In this problem

The tangent of angle of 5 degrees is equal to the quotient of "rise over run"

Let

y ----> the rise of the ramp

x ----> the run of the ramp

tan(5^o)=\frac{y}{x}

we have

y=5\ ft

substitute and solve for x

tan(5^o)=\frac{5}{x}

x=\frac{5}{tan(5^o)}

x=57.2\ ft

HELP PLEASE ASAP!!!!!!!!!!!!!!
Nesterboy [21]
A. Since the area of a triangle is equal to A = 0.5bh, we just plug in numbers given to us:
A = \frac{1}{2}bh= \frac{1}{2}(2x+7)(4x+6)= \frac{1}{2}(8x^2+40x+42)=4x^2+20x+21

So, that's your answer.

B. The answer is a 2nd-degree trinomial because it has three terms and it's highest exponent is 2.

C. Polynomials are closed under multiplication because if you multiply two polynomials, you get another polynomial (except if you multiply by the inverse which is excluded anyways).
