A B and D are not functions because when you draw a vertical line (Vertical line test) the line passes through 2 points of the graph where as in C, it is a function because when you draw a vertical line through the graph, the line only hits 1 point

C is a function. The must pass the vertical (up and down) line test. Put a vertical line on it. It it touches 2 points it is not a function.

tatiyna

Answer: 26 dollars

Step-by-step explanation:

The owner needs to consider that:

To measure the risk she can multiply the probability of an event to happen (P)* the impact (I) (in this case the impact is the cost).

All these eventes can be considered as independent between each other (no correlation), so you can add their P*I.

In this case:

P1*I1= 1%*550=5.5

P2*I2=6%*150=9

P3*I3=15%*100=15

So, the expected value of what she may spend for repairng is = P1*I1+P2*I2+P3*I3= 5.5+9+15= 29.5

She shoould not spend more than 29.5 dollars, otherwise, she will spend more in the surge supresor than in expected reapring value

Trangle s and tringle l are scaled copys of one another.

KATRIN_1 [288]

A) find the length of the bottom of both
S=2 units L=5 units

So S/L = scale factor

=2/5

B) L/S
=5/2

C) S/M=3/2
S=2
2/m=3/2
3m=2*2
3m=4
M=4/3

M/S=the opposite of s to m
So it is 2/3

frutty [35]

Answer:

Ball cannot be fit inside the box.

Step-by-step explanation:

Given:

Circumference of ball = 26 inches

Dimension of box = 8.25 in x 8.25 in x 8.5 in.

We need to find the whether ball gets fits inside the box.

First we will find the Diameter of ball.

Circumference of ball is given so we will find radius of the ball.

Circumference of the sphere is equal to 2 times π times radius.

framing in equation form we get;

$2\pi \times r =26\\\\r= \frac{26}{2\pi}= 4.14\ in.$

Now we will find the Diameter of the ball.

Diameter of ball is equal to 2 times radius.

framing in equation form we get;

Diameter of ball = $2\times 4.14 = 8.28\ in$

Now given that two parallel sides of box has dimension which is 8.25 in.

Since Dimension of box is smaller than diameter of the ball.

Hence we can say that ball cannot be fit inside the box.

Two angles are supplementary. One angle is 36 degrees bigger than the other. What is the measure of the bigger angle

Lorico [155]

let the other angle be x degree

bigger angle = x +36°

According to the question,

x+36° + x° = 180°

=> 2x = 180–36

=> x = 144/2

=> x = 72°

Measure of the bigger angle = x + 36

= 72° + 36°

= 108°
