Answer: There are 2635 acres covered 24 hours later.

Step-by-step explanation:

Since we have given that

At time t = 0, number of acres forest fire covers = 2008 acres

We first consider the equation:

A=\int\limits^t_0 {8\sqrt{t}} \, dt\\\\A=8\dfrac{t^{\frac{3}{2}}}{\frac{3}{2}}+C\\\\A=\dfrac{16}{3}t^{\frac{3}{2}}+C

At t=0, A= 2008

So, it becomes,

2008=C

So, now it becomes,

A=\dfrac{16}{3}t^{\frac{3}{2}}+2008\\\\At\ t=24,\\\\A=\dfrac{16}{3}(24)^{\frac{3}{2}}+2008\\\\A=2635.06

Hence, there are 2635 acres covered 24 hours later.

Which statement is true about the data?
vladimir1956 [14]

Answer:

B

Step-by-step explanation:

The diagram shows two box plots.

Liam's box plot shows the median = 10

                                     the range = 20 - 4 = 16  

Sumat's box plot shows the median = 14

                                     the range = 22 - 3 = 19

Difference between medians is 14 - 10 = 4

                  between ranges is 19 - 16 = 3

Thus, correct option is option B

if the federal reserve decreases the reserve rate from 5% to 2%, how does this affect the amount of money that would result beca
Mandarinka [93]
With a 5% reserve ratio, the Fed can create up to 1.05=20 times the initial deposit. With a 2% reserve ratio, it can create up to 1.02=50 times the initial deposit. So lowering the reserve ratio would increase the amount of money made. 50x−20x=30x, where x=$25,000.
