Look at points C and D on the graph:What is the distance (in units) between points C and D? Round your answer to the nearest hundredth.

3.46 units
8.49 units
12.00 units
72.00 units

Answers

Answer: 8.9 units

Step-by-step explanation:

From the given graph we can see the coordinates of C=(0,2)

The coordinates of D=(6,-4)

By using distance formula, we will find the distance between points C and D as:

CD= $√((x_2-x_1)^2+(y_2-y_1)2)$

$=√((6-0)^2+(-4-2)^2)\n=√(6^2+(-6)^2)\n=√(36+36)\n=√(72)=6√(2)\n=6*1.4142=8.4852\approx8.9\text{ units}$

$√((x_2-x_1)^2+(y_2-y_1)^2)\n\n√((0-6)^2+(2-(-4))^2)\n\n√((-6)^2+6^2)\n\n√(36+36)\n\n√(72)\n\n\boxed{8.49}$

How many yards are in 3 times of 4 yards 2 foot

Answers

4 yards and 2 feet is equal 14 feet since each yard is made up of 3 feet.

1 yard = 3 feet.

So if we take 14 feet and multiply that by 3 we get 42 feet.

42/3 is equal to about 14 yards in total

So the answer is 14 yards.

Which rotation about its center will carry a regular decagon onto itself?A. 54
B. 162
C. 198
D. 252
Please explain!!!

Answers

Answer:

D.252

Step-by-step explanation:

In this question, We have to find which rotation about its center will carry a regular decagon onto itself?

A decagon : 10 sided polygon

As we know, a full rotation can be 360°.

For a decagon: 360/10 =36

For a decagon, any multiple of 36 can map onto itself.

In our options only 252 is the multiple of 36.

So, correct answer is option D252

Answer:

1.)-8

2.)-5

3.)4

Step-by-step explanation:

So, the function f(x)=3x-5

The questions say "If you were to substitute these numbers what answer would you get?"

Understanding this,

First question is with x=-1

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

f(-1)=-3-5=-8

_____________________________________

f(0)=3(0)-5

f(0)=0-5=-5

_____________________________________

f(3)=3(3)-5

f(3)=9-5=4
