Describe the function over each part of its domain. State whether it is constant, increasing, or decreasing, and state the slope

Amanda [17]

The attached image completes the question.

Answer:

- The part (0, 12000) is constant and the slope is zero

- The part (12000, 38000) is decreasing and slope is negative 0.26.

Step-by-step explanation:

Checking the given graph, we see that

For x = 0 to x = 12,000, the values of y are unchanged. For this, we say it is constant.

The slope here is: 0.85 - 0.85 = 0

For x = 12,000 to x = 38,000, the values of y are decreasing. For this, we say it is negative.

The slope here is: 0.59 - 0.85 = -0.26.

What is the approximate value of b, rounded to the nearest tenth?

ozzi

we know that

m∠ZWY=m∠WXY --------> given problem

In the right triangle ZWY

$tan\ ZWY=\frac{ZY}{YW}=\frac{5}{6}$

In the right triangle XWY

$tan\ WXY=\frac{WY}{XY}=\frac{6}{a}$

$\frac{6}{a} =\frac{5}{6} \\ \\5*a=6*6 \\ \\a=\frac{36}{5}=7.2\ units$

Find the value of b

Applying the Pythagorean Theorem

In the right triangle XWY

$b^{2}=6^{2}+a^{2} \\b^{2}=6^{2}+7.2^{2}\\b^{2}=87.84\\ b= 9.4\ units$

therefore

the answer is the option

D) 9.4 units

Safe wheelchair ramp specifications require about 4.75° maximum angle to be constructed with the ground. At a particular buildin

NeTakaya

Answer:

The ramp must cover a horizontal distance of approximately 19.081 feet.

Step-by-step explanation:

Given the vertical distance ( $y$ ), measured in feet, and the angle of the wheelchair ramp ( $\theta$ ), measured in sexagesimal degrees. The horizontal distance needed for the ramp ( $x$ ), measured in feet, is estimated by the following trigonometrical expression:
