Answer:

2/5

Step-by-step explanation:

First, we need to find the slope of line a. To do this, we subtract the two y values and then the two x values and divide these two differences.

10-5=5

6-8=-2

5/-2= -5/2

A perpendicular line's slope will always be equal to the negative reciprocal of the intersects. So, we just flip the numerator and denominator and then add a negative to our first slope to get the slope of line b.

-2/5

--2/5

2/5

Have a wonderful day! :D

Kareem rented a truck for one day. There was a base fee of $14.95 , and there was an additional charge of 93 cents for each mile

Answer:

He drive the truck <u>292</u> miles.

Step-by-step explanation:

Given:

Kareem rented a truck for one day.

There was a base fee of $14.95, and there was an additional charge of 93 cents for each mile driven.

Kareem had to pay $286.51 when he returned the truck.

Now, to find the miles he drive the truck.

So, we deduct the base fee first:

$286.51 - $14.95 = $271.56.

So, the remaining amount = $271.56

Now, we divide the remaining amount by by charge of 93 cents for each mile driven:

Converting cents into $ = 93 cents = 93 ÷ 100 = $0.93.

$\$271.56\div \$0.93$

$=292\ miles.$

Therefore, he drive the truck 292 miles.

Write a factored form polynomial of least degree that has the real zeros shown in the graph.

oee [108]

Answer:

f(x) = (x+5)(x-1)(x-3)

Step-by-step explanation:

From the graph, we have that the function intercepts the x-axis at the points x = -5, 1,3

From here, we have

x = -5

x = 1

x = 3

So we have the factors as;

x + 5, x - 1 , x - 3

So what this mean is that we have the function as;

f(x) = (x+5)(x-1)(x-3)

When using your portable radio, you must push the "press to talk" button and wait one second before speaking. This is essential

KengaRu [80]

Answer:

Repeaters.

Step-by-step explanation:

This is essential to effective communication because your EMS system must use Repeaters.

These are machines used to carry signals across a great distance. We may be in ambulances or put around an EMS network in different areas. The repeater receives and re transmits signals from lower power systems, such as mobile and handheld phones, to a higher power.

Find the slope of -2,1 and -7,7

Simora [160]

Answer:

6/-5

Step-by-step explanation:

label the points, x1 y1, x2 y2, and subtract y2-y1, over x2-x1

7-1=6, -7-(-2)= -5

So, 6/-5, or, six over negative five
