A population grows exponentially at an annual rate given by r=0.03. What will the population be in 75 years if the initial population is 2500?
A stone dropped from rest travels 230 feet in the first 5 seconds. How far will it have fallen at the end of 7 seconds? (Round to the nearest Integer)
The revenue function is given by R(x) =x*p(x) dollars where x is the number of units sold and p(x) is the unit price. If p(x)=50(5)-x/5 find the revenue if 10 units are sold. Round to two decimal...
I do not know how to find x in this problem.
I ca not find the domain in interval notation and the intercepts as ordered pairs.
I can not find the rate of interest
Suppose that u varies directly as the square root of x, and that y=32 when x=9. What is y when x=19 (round to two decimal places)
It is supposed to be solved without a calculator! Please help! I am so confused. I thought the answer would be 10,000 (10^4), but it is not correct.
The equation is supposed to be solved without the calculator. Please help!
