Answer:
<u>Given equation and the graph of it:</u>
1. What does the 5 in the equation represent?
- 5 represent a height of the release of the rocket
2. What does 100t in the equation mean in terms of the rocket?
- 100t is determining the maximum height that the rocket can reach
3. Approximately when does the rocket hit the ground?
- As per the graph it is after 6.3 seconds it was launched
4. What domain makes sense for the function in this context?
<u>Domain of the function is:</u>
This is the time the rocket is in the air until it hits the ground
It is 36
Bcuz 3X6=18
And 18X2=36
Hope i helped ^_^

Answer:
(d) Both sales persons will earn a monthly salary of $5,000 for $25,000 in sales
Step-by-step explanation:
The variable definitions are ...
x = amount of sales
y = monthly earnings
Then the point (x, y) = (25000, 5000) means earnings are $5000 on sales of $25,000.
Answer:
There were 14 cartons of size 2 rackets and 24 cartons of size 3 rackets
Step-by-step explanation:
Assume that the number of cartons holding 2 rackets is x and the number of cartons holding 3 rackets is y
∵ There are x cartons of 2 rackets
∵ There are y cartons of 3 rackets
∵ They used 38 cartons
∴ x + y = 38 ⇒ (1)
∵ They packed a total of 100 rackets
∴ 2x + 3y = 100 ⇒ (2)
Let us solve the system of equations
→ Multiply equation (1) by -2 to make the coefficients of x in
the equations equal in values and different is signs
∵ -2(x) + -2(y) = -2(38)
∴ -2x - 2y = -76 ⇒ (3)
→ Add equations (2) and (3)
∴ y = 24
→ Substitute the value of y in equation (1) or (2) to find x
∵ x + 24 = 38
→ Subtract 24 from both sides
∴ x + 24 - 24 = 38 - 24
∴ x = 14
There were 14 cartons of size 2 rackets and 24 cartons of size 3 rackets
