Question 1: Car A began a journey from a point at 9 am, traveling at 30 mph. At 10 am car B started traveling from the same poin

t at 40 mph in the same direction as car A. At what time will car B pass car A?
Solution:
Let after t hours the distances D1 traveled by car A

=> D1 = 30 t

Car B starts at 10 am and will therefore have spent one hour less than car A when it passes it.

After (t - 1) hours, distance D2 traveled by car B

=> D2 = 40 (t - 1)

When car B passes car A, they are at the same distance from the starting point and therefore D1 = D2

=> 30 t = 40 (t - 1)

Solve the equation for t,

William Right broke his leg in an accidental fall. He has a deductible of $150 and a coinsurance payment equal to 20% percent of
Varvara68 [4.7K]

We know that William paid his deductible that amount is the $150. 

Then William paid 20 percent of everything else. That's 20 percent of (750 minus 150), it is equal to 150.

Then the insurance company paid 80 percent of (750 minus 250), it is equal to 480.

Answer:

Please check the explanation.

Step-by-step explanation:

Given the polynomial function

f\left(x\right)\:=x^3+2x^2-16x-32

Let us determine the factors by solving

\:\left0\right\:=x^3+2x^2-16x-32\:

\left(x+2\right)\left(x+4\right)\left(x-4\right)=0

Using the zero factor principle:

if  ab=0\:\mathrm{then}\:a=0\:\mathrm{or}\:b=0\:\left(\mathrm{or\:both}\:a=0\:\mathrm{and}\:b=0\right)

x+2=0\quad \mathrm{or}\quad \:x+4=0\quad \mathrm{or}\quad \:x-4=0

Thus, (x+2) (x+4) and (x-4) are the factors of the polynomial function.

Therefore,

YES

  • (x+2)
  • (x+4)
  • (x-4)

And (x-2) (x+6) are not the factors of the polynomial function.

Therefore,

YES

  • (x-2)
  • (x+6)

First, figure out how much Aniyah started with.  Add.  Show your work.

Then, write out the fraction (amount spent) / (amount Aniyah began with).

Last, multiply your result by 100%, and then round off the resulting percentage to the nearest integer number.
