Answer:
The linear equation is;
Y = 450 - 2·X
Please find the included graph
Step-by-step explanation:
Whereby we have the following relation;
The cost of 1 pizza = X
The cost of 1 burger = Y
Hence;
450 = Y + 2·X
Which gives;
Y = 450 - 2·X
The linear equation for the situation is therefore as presented above
The graph of the linear equation can be plotted using the assumed data as follows;
Y, X

Answer with Step-by-step explanation:
Since we have given that
Initial height = 3 feet
The baseball hits the ground after 2 seconds
t = 2 seconds
So, final velocity = v = 0
a. What was the initial velocity of the baseball?
Initial velocity is given by
b. What is the function that models the height, ℎ (in feet), of the baseball over a period of time tt (in seconds)?
As we know that the function of height would be
Here, is the initial height.
So, our function becomes,
c. At what time did the baseball reach its maximum height? What was the maximum height of the baseball?
Maximum height at time t:
Maximum height would be
Answer:
10m
Step-by-step explanation:
Use the area of triangle:
Area of triangle =
1/2 × b × 3 = 15
b × 3 = 30
b = 30/3
b = 10
