Answer: its is you figer it out okay haha

Step-by-step explanation: im jokeing

Kinetic energy = 1/2 M V2

At the lower speed, the car's KE is (500) (1)2 = 500 joules

At the higher speed, the car's KE is (500) (2)2 = 2,000 joules

The difference is the energy i.e. the work you have to put into it

to raise the speed from 1 m/s to 2 m/s.

(2,000 - 500) = 1,500 joules there u go :D

The walls are vertical so the angle opposite X would be a right angle which is 90 degrees.

X would be 180 - 90 - 35 = 55 degrees

X and 2y - 5 are complementary angles which add together to equal 90:

2y - 5 + 55 = 90

Simplify:

2y +50 = 90

Subtract 50 from both sides:

2y = 40

Divide both sides by 2:

y = 20

1st is to make the numbers into ratios. Basically taking the two numbers and putting them in the middle. I’ll do the 1st 15:36.
Next you put it into a fraction: 15/36
Put in the comments if you want me to do all or if you have any questions!

Show work what is the measures
noname [10]
Set it up 180=(7x+10)+ z because angle b is on the flat line and then solve for x (180-10, then 170/7) and you’ll get the value of x and from there you can put it in all
