Does anyone get this​
ivolga24 [154]

Answer:

Step-by-step explanation:

Ok so to find constant of proportionality, you need to find K.

X would be gallons and y is cost.

To find k you need to do k=y/x

k=17.50/5

k=3.5

That's the first one. Now you need to make sure its <em>constant</em> with each one so keep going.

k=35/10

k=3.5

k=52.50/15

k=3.5

For all of those 3.5 was constant.

Because they are constant, that means the data in the graph is a proportion.

An example of an unproportional relationship would be if instead of 15 in the last column, it was 16.

k=52.50/16

k=3.28

That be different from the other 3.5's meaning its not proportional. But that's just an example.

If you need extra help reach out to me and I'll help you best I can. I hope this helps though. <3

if you lose 3 1/2 pounds the first week of your diet and 2 2/3 pounds the second week, how many pounds do you still need to lose
Olin [163]

Answer:

3 5/6

Step-by-step explanation:

3 1/2 plus 2 2/3 equals 6 1/6. 10 minus 6 1/6 equals 3 5/6. So they still need to lose 3 5/6 pounds to reach their go of losing 10 pounds.

A soccer ball is kicked in the air off a 22.0 meter high hill. The equation h(t)=-5t^2+10t+22 gives the approximated height h, i
Lana71 [14]

Answer:

Equation: 5t² − 10t + 13 = 0

Answer: No

Step-by-step explanation:

h(t) = -5t² + 10t + 22

When h(t) = 35:

35 = -5t² + 10t + 22

5t² − 10t + 13 = 0

This equation must have at least one real solution if the ball is to reach a height of 35 meters.  Which means the discriminant can't be negative.

b² − 4ac

(-10)² − 4(5)(13)

100 − 260

-160

The ball does not reach a height of 35 meters.
