Part 1:

You know the height of a telephone pole and the distance the support cable is from the base of the telephone pole, but you don't know the length of the cable. The cable needs to be replaced so you need to calculate the length.

What is the length of the cable?

Part 2 and Part 3: See the attached picture:

Answer:

Part 1: you know the height of the latter and the distance of the slide to the latter, but you don't know the length of the slide that needs to be replaced due to being broken.

i used a slide. the height of a ladder is 10 ft, the distance from the ladder and the end of the slide is 20 ft. so you needed to find the length of the slide to complete your "triangle".

i cannot add a picture so i hope you can work with that. you can also alter the numbers so that it isnt the same when you turn it in (turnitin will detect if another student put this answer) so i suggest altering the numbers.

here is my work:

10^2 + 20^2 = x^2

100 + 400 = x^2

500 = x^2

√500 = 22.360679775

22.360679775 = 22.3

x= 22.3

So the slide is about 22 feet long.

Which is not a characteristic of the absolute value parent function

timama [110]

Answer:

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

$f\left(x\right)=\left|x\right|$

see the attached figure to better understand the problem

A. it is v-shaped ------> Is true

B. the range is all real numbers ------> Is not true

Because the range is the interval------> [0,∞)

$y\geq 0$

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

Find the equation for the plane that contains the line x=−1+3t , y=1+2t, z=2+4t and is perpendicular to the plane containing the

Ivan

Let $L$ be the line given by the vector equation

$(-1,1,2) + \lambda(3,2,4) \ , \lambda \in \mathbb{R}$ .

First, we use the director vectors of the lines L1 and L2 to get the

vector equation of the plane containing them, which we denote by $\Pi_1$ . This is,

$\\\\\Pi_1 : (1,-1,5) + \alpha (2,-1,6) + \beta (1,1,-3) \ , \alpha, \beta \in \mathbb{R}\\\\\\$

We observe that $\vec{N} = (2,-1,6)\times(1,1,-3) = (-3,12,3) \ne (0,0,0)$ . Therefore, the vector equation of $\Pi_1$ defines a plane and $\vec{N}$ is a normal vector to $\Pi_1.$

Finally, the vector equation for the wanted plane, which we denote by $\Pi$ , is

$\Pi : (-1,1,2) + r(3,2,4) + s(-3,12,3), r,s \in \mathbb{R} \ .$

Thus, if $s = 0$ , then $L \subset \Pi$ and since $\vec{N}$ is parallel to $\Pi$ , then it is perpendicular to $\Pi_1$ .
