Has anyone done Exponential Growth and Decay (in mathematical models with application A) on sos or odysseware and gotten a prefe

Lilit [14]

Answer:

1) 62.5

2) 50

3) 75

4) 100

Step-by-step explanation:

1)

Because it has a half-life of 25 days, half of it will decay after 25 days.

After $25*4=100$ days, there will be $(1/2)^{4}=1/2^{4}=1/16$ of it left.

So, $1000/16=\boxed{62.5}$ .

2)

Because it has a half-life of 25 days, half of it will decay after 25 days.

After $25*3=75$ days, there will be $(1/2)^{3}=1/2^{3}=1/8$ of it left.

So, $400/8=\boxed{50}$

3)

Because it has a half-life of 25 days, half of it will decay after 25 days.

After $25*2=50$ days, there will be $(1/2)^2=1/2^{2}=1/4$ of it left.

So, $300/4=\boxed{75}$ .

4)

The only answer left is $\boxed{100}$ grams. You can solve it the same way you solved the previous steps.

scott is riding a bike course that is 50 miles long. So far, he has ridden 6 miles of the course. What percentage of the course

ad-work [718]

Scott has ridden 12% of the course.

Step-by-step explanation:

Length of bike course = 50 miles

Distance covered = 6 miles

Distance covered in percentage = $\frac{Distance\ covered}{length\ of\ bike\ course}*100$

Distance covered in percentage = $\frac{6}{50}*100\\$

Distance covered in percentage = $\frac{600}{50}$

Distance covered in percentage = 12%

Scott has ridden 12% of the course.

Keywords: percentage, distance

Makovka662 [10]

Answer:

#1). 6 , 18 , 54

#2). 5/3 , 14 / 9 , 41/27

#3). 1.5 , 2.5 , 2.5

Step-by-step explanation:

#1).

g(x) = 3x

g(2) = 3 . 2 = 6

g²(2) = 3 . 3 . 2 = 18

g³(2) = 3 . 3 . 3 . 2 = 54

#2).

g(x) = 1/3 x + 1

g(2) = 2/3 + 1 = 5/3

g²(2) = g(5/3) = 5/9 + 1 = 14/9

g³(2) = g(14/9) = 14/27 + 1 = 41/27

#3).

g(x) = -1 ║x - 2 ║ + 3

g(0.5) = -1 (1.5) + 3 = 1.5

g²(0.5) = g(1.5) = -1(0.5) + 3 = 2.5

g³(0.5) = g(2.5) = -1(0.5) + 3 = 2.5
