A rhombus has sides 10 cm long and an angle of 60°. Find the diagonals of the rhombus.

Answers

Since all the sides are equal, the altitude is

10 sin60° = 5√3

To see this, draw the rhombus ABCD and drop an altitude from D to AB. Now you have a right triangle with hypotenuse=10 and base angle=60°

0.2 ( 10 - 5c ) = 5c - 16

Answers

Answer: c = 3

Step-by-step explanation: Distribute 0.2 to (10-5c)

2-1c=5c-16

Then subtract 2 on both sides and subtract the 5c.

-1c=5c-18

-6c=-18

Then divide -6 to -18

-18/-6 = 3

Step-by-step explanation:

So, what is scaling?

Scaling is basically when a shape is inlarged or shruken by a specific amount on all sides.

In this case, one of the shapes side's is 10.

Now, they say that the scale value is more than 1. What does this mean?

It means that the new, scaled number is going to be at least as big as 10.

We dont have to worry about finding a exact number, since they do not give us any information to scale with.

So, all we have to do is look at the graph, and see what numbers are larger than 10.

Is 2 units larger than 10? No, thats only about 1/5 the orginal size, not larger than 1.

Is 5 units larger than 10? No, thats only abouit 1/2 the orginal size, not larger than 1.

How about 11? Is it larger than 10? Yes, its about 11/10 the orginal size, which is bigger than 1.

Finally we have 23? Is it larger than 10? Yes, its a little over 2 times bigger than the orginal size.

So your two answers are:

11 and 23

Hope this helps! :)

Answers

Answer:

y=-4/5x+2

Step-by-step explanation:

SORRY FOR THE LATE RESPONSE

slope-intercept form is y=mx+b

b is the y-intercept -> 2

m is the slope, which would be the rise/run -> -4/5

to identify the slope all you need to do is pick two points on the line, and find the direction of the line from left to right. rise/run basically means you find the distance going up and down first, and then the distance from left to right next.

now just put the equation together-> y=-4/5x+b

let me know if this helped, or was even right lol

CLAIM:

Examine the system model below, which shows a car moving along a track at two different points in time. Assume there is no friction between the car and the track.


In the before image, a car is moving along a track at a constant speed towards a motionless wheel.


In the after image, the car has contacted the wheel, which begins to spin. The car continues to travel along the track at a slower speed.


THE QUESTION:

Which Claim below best explains what causes the wheel to spin after contact with the car?

1 - The wheel stops spinning because kinetic energy was transferred from the car to the wheel.

2 - The wheel begins to spin because kinetic energy was transferred from the car to the wheel.

3 - The wheel pushes the car, causing it to go faster

4 - The wheel begins to spin because kinetic energy was transferred from the wheel to the car.

Answers

Answer:
