Answer:

12, 7, 2, -3, -8

Step-by-step explanation:

I will only do the first one for an example.

If x was to equal -2 you would put it into the function like this.

f(x)=2-5x

f(-2)=2-5(-2)

f(-2)=2+10

f(-2)=12

Just in case you didn’t know, you can also use photomath, for math problems. They give you the answer and they also include the steps. You can do that instead of waiting for someone to answer here, it’ll be alot faster:)

Find the length of AP in the diagram below, rounding to the nearest tenth

tester [92]

Answer:

6.9 to the nearest tenth.

Step-by-step explanation:

Use the external tangent - chord theorem:

AP^2 = CP * BP

AP^2 = 12 * 4 = 48

AP = √48

= 6.928

Can someone please answer these *will give brainliest if you answer all* AND NO LINK

Jobisdone [24]

Answer:

Rectangular Prism → h = 2in

B = 143in

P = 48in

Surface Area = 382in²

Lateral Surface Area = 96in²

Triangular Prism → h = 7in

B = 20in

P = 27in

Surface Area = 229in²

Lateral Surface Area = 189in²

Triangular Prism → h = 10in

B = 120in

P = 60in

Surface Area = 840in²

Lateral Surface Area = 600in²

Step-by-step explanation:

Formulas: Total Surface Area = 2B = Ph

a²+b²=c²

Area = $\frac{1}{2}$ bh

Lateral Area = Ph

PLUG NUMBERS INTO FORMULA. (I'm too lazy to type it all out lol)

You are sitting at the edge of the Grand Canyon admiring the view when you notice a tour group at the bottom of the canyon. You

Answer:

7949.13 feet

Step-by-step explanation:

We are given that,

Angle of depression from the spot to the group = 39°

Height of Grand Canyon = 5000 feet.

So, we will get the following figure of a right triangle.

As, 'in a right triangle, the angles and the sides can be written in trigonometric form'.

We get, $\sin A=\frac{perpendicular}{hypotenuse}$

i.e. $\sin 39=\frac{5000}{x}$

i.e. $x=\frac{5000}{\sin 39}$

i.e. $x=\frac{5000}{0.629}$

i.e. x = 7949.13 feet

Thus, the line of sight distance is 7949.13 feet.
