Hello,

We suppose y ≠5
$(y^3-125)/(y-5)=((y-5)(y^2+5y+25))/(y-5)=y^2+5y+25$

5% tax on $20 is $

Answers

5% tax on 20 dollars.
First let's convert 5% to decimal
=> 5% / 100 = .05
Next is to simply multiple 0.05 to 20 dollars
=> 20 * .05 = 1 dollar.
Thus. the 5% of 20 dollars is 1 dollar.

If there is 360 grams of radioactive material with a half-life of 8 hours, how much of the radioactive material will be left after 32 hours and is the radioactive decay modeled by a linear function or an exponential function?A. 22.5 grams; linear

B. 22.5 grams; exponential

C.45 grams; linear

D. 45 grams; exponential

Answers

B.) 22.5 GRAMS, EXPONENTIAL

32 hours ÷ 8 hours = 4

The radioactive material will half 4 times.

360 x (1/2)⁴ = 22.50

360 x 1/2 = 180
180 x 1/2 = 90
90 x 1/2 = 45
45 x 1/2 = 22.50

Answer:

B. 22.5 grams; exponential .

Step-by-step explanation:

We have been given that there is 360 grams of radioactive material with a half-life of 8 hours.

As amount of radioactive material remains 1/2 of the amount after each 8 hours, therefore, our function will be an exponential decay function.

We will use half-life formula to solve our given problem.

$y=a*((1)/(2))^{(t)/(b)}$ , where,

$a=\text{Initial value}$ ,

$t=\text{Time}$ ,

$b=\text{Half life}$ .

Let us substitute a=360 and b=8 in half life formula to get half life function for our given radioactive material.

$y=360*((1)/(2))^{(t)/(8)}$ , where y represents remaining amount of radioactive material after t hours.

Therefore, the function $y=360*((1)/(2))^{(t)/(8)}$ gives the half-life of our given radioactive material.

Let us substitute t=32 in our half life function to find the amount of material left after 32 hours.

$y=360*((1)/(2))^{(32)/(8)}$

$y=360*((1)/(2))^(4)$

$y=360*(1^4)/(2^4)$

$y=360*(1)/(16)$

$y=22.5$

Therefore, the radioactive material will be left 22.5 grams after 32 hours and the radioactive decay is modeled by an exponential function and option B is the correct choice.

Answers

Answer:

49 pi in^2 or approximately 153.86 in^2

Step-by-step explanation:

A = pi r ²

Let r = 7

A = pi 7 ²

A = 49 pi

If we approximate pi by 3.14

A is approximately 153.86 in^2

The answer is about 153.938
