Answer:
-8 < -4
Step-by-step explanation:
$900, but not too sure if this is a question to trick you.
Step-by-step explanation:
I assume that "ground" is at 0 ft height. which is in an actual scenario not airways the case.
y = -16x² + 64x + 89
shows us that the tower is 89 ft tall (the result for x = 0, at the start).
anyway, if the original assumption is correct, then we need to solve
0 = -16x² + 64x + 89
the general solution for such a quadratic equation is
x = (-b ± sqrt(b² - 4ac))/)2a)
in our case
a = -16
b = 64
c = 89
x = (-64 ± sqrt(64² - 4×-16×89))/(2×-16) =
= (-64 ± sqrt(4096 + 5696))/-32 =
= (-64 ± sqrt(9792))/-32
x1 = (-64 + 98.95453501...)/-32 = -1.092329219... s
x2 = (-64 - 98.95453501...)/-32 = 5.092329219... s
the negative solution for time is but useful here (it would be the time calculated back to ground at the start).
so, x2 is our solution.
the rocket hits the ground after about 5.09 seconds.
The <u>correct answers</u> are:
Unemployed people usually buy fewer things.
Unemployed people may not be able to repay their loans.
Unemployed people may have to to change their financial goals.
Explanation:
If someone is unemployed, they have much less money with which to purchase items, so they usually purchase less. This hurts the businesses that would profit from these purchases.
If someone is unemployed, their ability to pay their bills is affected since their income is gone. This means they may not be able to repay any loans they have in their name. This hurts the banks that have loaned the money.
If someone is unemployed, they may have to adjust their financial priorities. If they were looking to invest money, they no longer have it to invest. If they were looking to purchase real estate, again, they no longer have the money to do that. This hurts banks that they may invest through and the people or agencies that they would be purchasing real estate through.
