Answer:
x = -3
Step-by-step explanation:
Since they give you the function in binomial factor form, it is very straight forward to find what its zeroes are: Those x-values for which any of the binomial factors renders zero would be a so called "zero" of the function.
We examine each of these binomial factors [ (x+3), (x-7) and (x+5) and notice that for the factor:
(x+3) to be zero, x needs to be equal to "-3",
(x-7) to be zero, , x needs to be equal to "7",
(x+5) to be zero, , x needs to be equal to "-5".
therefore, from the options they give you, only "x= -3" is correct.
Answer:
100.7%
Step-by-step explanation:
Since the interest is compounded quarterly, and there are 4 quarters per year, that would leave us with 32 quarters total where interest is acquired. Now, we need to find the interest rate, that would be required in order to end up with 420 dollars after 32 quarters.
We can setup a formula using our period of time and the money he invested into the bank:
We can divide 340 from both sides, and simplify the right side to 21 divided by 17:
Taking the 32th root of 21/17 is equal to 1.00662, which is equal to 100.0662%. To the nearest tenth of a percent, this is equal to 100.7%.
