A ladder is leaning against the side of a building and positioned such that the base of the ladder is 17 ft from the base of the building. If the ladder reaches 23 ft above the ground, how long is the ladder. Round your answer to the nearest tenth

The ladder is 28.6 feet long.

Step-by-step explanation:

Given that:

Length of base = 17 feet

Length above the ground = 23 feet

These forms two legs of right angled triangle.

The length of ladder will be the hypotenuse.

Using Pythagorean theorem;

Taking square root on both sides

Hence,

The ladder is 28.6 feet long.

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true

step-by-step explanation:

answer is  

c.
