Answer:
One day rental is $44
C = 44d is the equation
1:44 is the ration
Step-by-step explanation:
To get the daily rate we take the total cost and divide by days:
220 / 5 = 44
O = 7*180 = 1260 degrres
sin O = 0
Answer:
yes she has more than enough
Step-by-step explanation:
1 quart = 4 cups
2 quarts = 8 cups
3 quarts = 12 cups
Using the information given and linear function concepts, it is found that:
- a) The equation is:
.
- b) The skydiver’s altitude after the parachute has been open for 2 minutes is of 2000 feet.
- c) It takes 200 seconds for the skydiver to reach the ground.
<h3>What is a linear function?</h3>
A linear function is modeled by:

In which:
- m is the slope, which is the rate of change, that is, by how much y changes when t changes by 1.
- b is the y-intercept, which is the value of y when x = 0.
Item a:
- The skydiver descends at a rate of 25 feet per second, hence
.
Then:

<u>90 seconds after the parachute opens, his altitude is 2750 feet</u>, which means that when
, which is used to find b. Then:


Hence, the equation is:
.
Item b:
Time is in seconds, hence, this is y(120).

The skydiver’s altitude after the parachute has been open for 2 minutes is of 2000 feet.
Item c:
The time it takes to reach the ground is t for which y(t) = 0, hence:




It takes 200 seconds for the skydiver to reach the ground.
