Answer:

It will take Superman 32.71 hours or 32 hours and 43 minutes

Step-by-step explanation:

Convert kilometers to meters

40,075 kilometers = 40,075,000 meters

\frac{340.29meters}{1 second} = \frac{40,075,000 meters}{x seconds} Cross multiply

340.29x = 40,075,000

x = 117,767.19 seconds

Convert seconds to hours

\frac{3600 seconds}{1 hour} = \frac{117,767.19 seconds}{x hours} Cross multiply again

3600x = 117767.19

x = 32.71 hours or 32 hours and 43 minutes

Construct a polynomial function with the following properties: fifth degree, 4 is a zero of multiplicity 3, −4 is the only other
Nonamiya [84]

Answer:

Step-by-step explanation:

Hello,

degree 5

4 is a zero of multiplicity 3 -> (x-4)^3 is a factor

-4 is the only other zero, so the multiplicity is 5-3=2 -> (x+4)^2 is a factor

leading coefficient is 4 so we can write

\boxed{4(x-4)^3(x+4)^2}

If there is something that you do not understand or you are blocked somewhere let us know what / where.

Thank you.

Holly checked her answer to a division problem by estimating the quotient. Which is the best estimation of the quotient?
Andre45 [30]
Answer: 4

Try just dividing 23/5 and you’d get 4 something. But since 5.97 is close to 6 you can also mentally divide 23/6 and get 3something (it’d be really close to 4)
