Answer:
The Maximum Height reached by the rocket is 456.1 feet
Step-by-step explanation:
In order to calculate the maximum height reached by the rocket we would have to calculate first the derivative of y=-16x^2+147x+118 as follows:
derivative of y=-16x^2+147x+118=y'=dy/dx=d/dx(-16x^2+147x+118)
y'=-32x+147
Therefore, x=147/32
x=4.59375
Therefore, the maximum height reached by the rocket=-16*4.59375^2 + 147*4.59375 + 118
The maximum height reached by the rocket=456.1
The Maximum Height reached by the rocket is 456.1 feet

Step-by-step explanation:
Answer:
I can't draw the graph for you here, but the y intercept is 3, and the slope is -1.
Step-by-step explanation:
First you plot a point on the y axis at 0,-3
Then you want to do a rise over run, doing -1,1 until you get enough points to graph the line.
Let's say a = number of ordered soups, b = number of ordered sandwiches.
Then 4.5a + 7.75b = 113.50, and a and b are integers between 0 and 18 inclusive.
How do we tackle this? If all ordered soup, the cost would be $81, so we'll have at least 4 sandwiches. If all ordered sandwich, the cost would be $139.5, so at most 15 sandwiches were ordered. You also know an even number of sandwiches was ordered, to let the price end at 50 cent.
If you brute-force from 4,6,8,10,12 to 14 sandwiches, you find the answer at 10 sandwiches and 8 soups.
10*7.75 + 8*4.50 = 113.50
