Answer:
3,500
Step-by-step explanation:
70% is equal to 0.70.
When you need to find a percent of a population, you multiply the decimal form to the population.
Therefore, with 70% of 5000, you multuiply 5000 by 0.70 which will give you 3500.

Answer:
This question is a rather easy one which can be answered by simply solving the embedded quadratic equation.
f(x) = - + 6x + 16
To make our solving easier, what we do is multiply the whole equation by -1. By so doing, we make "x" positive. Then, we have
f(x) = - 6x - 16
Solving this equation quadratically, we have
+ 2x - 8x - 16 = and when we factorize this expression, we have
x(x + 2) -8(x + 2) =
(x - 8) (x + 2) = 0
x - 8 = 0, x + 2 = 0
x = 8, or x = -2
Since distance can not be in negative(minus), we then have our x to be 8 meters.
