Answer:
h =12
Step-by-step explanation:
Therefore, by geometric mean property:
Answer:
p = $15d - (7,000 + 0.84d)
Step-by-step explanation:
In this question, we are asked to given an equation that will represent the profit Dion makes when he has made a total of d deliveries.
We proceed as follows:
To calculate the profit, we need to subtract the cost price from the selling price.
Let’s start with the cost price. This refers to the total amount of money that is used to prepare the goods for sales and also spent on that cause. He charges $0.42 for gasoline per trip. This means it is a total of $0.84 for each delivery. This is because two trips will make a delivery. Total number of money spent on gasoline on deliveries is thus 0.84 * d = 0.84d. Now, we add the cost of Motorcycle he rides to be $7,000. The total money spent is thus $7000 + $0.84d
His selling price is simply the number of deliveries he has made multiplied by the amount of money he charges per trip. This is same as 15 * d= $15d
Profit is thus ; p = $15d - (7,000 + 0.84d)
First we want to calculate at what height and at what time rocket stops ascending.
h' = 256 - 32t = 0
32t = 256
t = 8
h = 256*8 - 16*8^2
h = 1024
Now we want to find time at which it gets 200 feet that means our equation is:
200 = 256t - 16*t^2
-16*t^2 + 256t - 200 = 0
t1 = 0.82s
t2 = 15.17s
time t1 is when rocket is ascending and t2 when it is descending therefore answer is t2
