Step-by-step explanation:
F(x) = (x + 7)³
= 3C0 * x³ + 3C1 * x² * 7 + 3C2 * x * 7² + 3C3 * 7³
= x³ + 21x² + 147x + 343.
Answer:
The question gives you V0 as 220, so plug that in first.
h=-16t2+220t.
Then it says to find the time (solve for t), when the height is 400 ft. Plug 500 ft in as h and solve for t.
500=-16t2+220t.
To solve this, set the quadratic equal to 0 by subtracting 500 from both sides (0=-16t2+220t-500) and use the quadratic formula!

C because you have to divide by m or the members because you are splitting it up or dividing it between the members. And you subtract 95 dollars becuase it was a cost or bill
Answer:
900 L
Step-by-step explanation:
Let x be the number of litres when the tank is full.
Then 5/6 x - 30 = 4/5 x
Solve this by converting to /30:
25/30 x - 30 = 24/30 x
1/30 x = 30
x = 30*30 = 900
