A study of the annual population of gray squirrels in a Texas state park shows the population, S(t), can be represented by the f

Anastasy [175]

The growth rate of the given function is A) 1

Step-by-step explanation:

Step 1; To calculate the rate we need to see the difference between values at different periods of time. We need to calculate the population at different times.

For t = 1 years, S(t) = 273(1.073)t = 273 × 1.073 × 1 = 292.929,

For t = 2 years, S(t) = 273(1.073)t = 273 × 1.073 × 2 = 585.858,

For t = 2 years, S(t) = 273(1.073)t = 273 × 1.073 × 1 = 878.787.

Step 2; To calculate the growth rate, we divide the difference in the values of the present year and the past year by the value in the past year.

Growth rate between t = 1 and t = 2, Growth rate = S(t=2) - S(t=1) / S(t=1)

= 585.858 - 292.929 / 292.929 = 1.

Growth rate between t = 2 and t = 3, Growth rate = S(t=3) - S(t=2) / S(t=2)

= 878.787 - 585.858 / 585.858 = 1.

So the growth rate is A) 1.

Juan drove to the mountains last weekend. There was heavy traffic on the way there, and the trip took 8 hours. When Juan drove h

kolezko [41]

Answer:Juan live 384 miles from the mountains.

Step-by-step explanation:

Let x be the speed of Juan for trip to the mountains

Time taken by Juan to reach the mountains=8 hours

then distance traveled by Juan for trip to mountain= speed × time=8x..........(1)

Time taken by Juan to reach the home= 6 hours

Speed increased by 16 miles per hour ∴ the resultant speed to reach the home by Juan =x+16

then distance traveled by Juan to reach the home =speed × time

= (x+16)6......................(2)

Now distance is same in both the case (1) and (2),we get

8x= (x+16)6

⇒8x=6x+96..............(by solving brackets)

⇒2x=96..............(subtracting 6x from both sides )

⇒x=48....................(dividing 2 from both sides)

Putting this value in (1) ,we get

Distance traveled by Juan for trip to mountain =8×48=384 miles.

∴ Juan live 384 miles from the mountains.
