A.

function

B.

not a function

Answer:
A) A

B) A

C)A

D) B

Reason I know this is because if we look at the x number in all of these, if 2 are the same (like 2,6 and 2,4) then its a non function.

But if none of the x =the same value its a function.

Same goes for B

C

and now D, is a non function because out X's:

3

5

5

7

5 was repeated so it's a nonfunction.

Got it?

(I also just took this test XD)

tim makes 80 gallons of paint by mixing 48 gallons of green paint with 32 gallons of blue paint what part of every gallon is from green paint.

Help me please i really need help a lot of opints

What's.725put into a fraction

The side view of a house( The "side elevation") is often in the shape of a pentagon. If the angle at the roof is 150 degrees and there are two other angles of 90 degrees, what is the sum of the measures of the other two angles? Explain ,please! =)

If i buy 4 cans of soup for $6.00 which proportion can be used to find the cost of 13 cans

x = -1 is the answer to -2x2+x+8=0

If the box is truly a cube, then all 3 of its dimensions are the same . . . the cube root of 90. There's no "might" about it.

The first question above number 4 is A the first one the answer for number/question 4 is B. and that last question is A. and B. im sure of it please let me know if im right

it was going 3.34 kg a minute

energy is always transformed from one form to another

energy is not created nor destroyed

so when a car starts moving the chemical potential energy of the car is converted to kinetic energy

kinetic energy is the energy that moving objects possess

kinetic energy formula is as follows

Kinetic energy = 1/2 mv²

where m - mass

v - velocity

substituting these values

K.E = 1/2 x 1350 kg x (12 m/s)²

= 1/2 x 1350 x 144 = 97200 J

the kinetic energy of the car is 97.2 kJ

Hello!

**A 1350 kg car travels at 12 m/s. What is it's kinetic energy ?**

We have the following data:

m (mass) = 1350 kg

v (velocity) = 12 m/s

KE (kinetic Energy) = ? (in Joule)

**Formula to calculate kinetic energy:**

**Solving:**
