Step-by-step explanation:

For every 4 feet that the ladder rises, the bottom of the ladder should be 1 foot away from the wall. If you are going to climb onto a roof, the ladder should extend 3 feet higher than the roof. Also, the upper and lower sections of an extension ladder should overlap to provide stability

Write an equation for a rational function with: Vertical asymptotes at x = -1 and x = 3 x intercepts at x = -2 and x = -6 Horizo
dlinn [17]

Answer:

\frac{7(x+2)(x+6)}{(x+1)(x-3)}

Step-by-step explanation:

The vertical asymptotes need to be in the denominator. They become VA's when that small expression value equals zero.

x=-2 will become (x+2)

and x=-6 will become (x+6)

The x intercepts will be in the numerator.

x=-1 will go with (x+1) and x=3 will go with (x-3)

The horizontal A must be the quotient of the coefficient of the numerator and denominator, since both the top and bottom have the same power.

To make the quotient 7, we place a seven in the numerator so 7/1=7.

What is the measure of angle x? Help me plzzzz
Svetllana [295]

Answer:

x  =  60 ∘

Explanation:

As indicated by the markings, all the sides of this triangle are equal, and therefore all the angles of this triangle must be equal as well.

Let  x  be an angle,

so by the triangle sum theorem, we can say that:

3  x  = 180 ∘

x  =  60 ∘

If the length of a rectangle is increased by 120%, and its width is decreased by 20%, what is the percentage change in the area
velikii [3]

Answer:

The area of the rectangle is increased in 76 percent.

Step-by-step explanation:

The area of a rectangle (A) is represented by the following formula:

A = w\cdot l

Where:

w - Width.

l - Length.

If length is increased by 120 %and width is decreased by 20 %, the percentage change in the area of the rectangle is: (l = 2.2\cdot l_{o}, w = 0.8\cdot w_{o})

A = (2.2\cdot l_{o})\cdot (0.8\cdot w_{o})

A = (2.2)\cdot (0.8)\cdot w_{o}\cdot l_{o}

A = 1.76\cdot A_{o}

The area of the rectangle is increased in 76 percent.
