Step-by-step explanation:
- Masses of the bodies are x and y
- Distance at which they are kept is r
- When two bodies are of masses x and y are placed at a distance r then the gravitational force acting on them is given as:

- Where G is the gravitational constant.
Answer: 1 : 20%
2 : 80%
3 : -90% (negative 90%), if no negatives are allowed, than it is a 90% decrease.
4 : $90
5: $31.50
Step-by-step explanation:
Only 19 is a function because a function only has one y value for every x value. For the other graphs, there are at least two y values for each x value.
Answer:
$11.45
Step-by-step explanation:
Find the unit rate by dividing the total money by the total gallons.
33.90 / 14. 8 = 2.29 per 1 gallon.
This means 5 gallons will cost 5*2.29 = 11.45
Answer:
576
Step-by-step explanation:
First off, we can use the area of a kite formula, (D1*D2)/2 to get the area of one side of the kite, which is simplified to 18 * 32 : which gets us 288. But because we are looking for the area of the front and back side, we multiply 288 by 2- getting the final answer of <u>576</u>.
