The amount (in megawatts) of energy generated in a country from wind power can be modeled by the function W(t)equalsw0(1.90)

Ad libitum [116K]

Answer with Step-by-step explanation:

We are given that

$W(t)=W_0(1.90)^t$

Where t corresponds to the year 2000=0

a. $W(0)=2540MW$

Substitute the values

$2540\times 10^6=W_0(1.90)^0=W_0$

$W_0=2540MW$

b.In 2004

t=4

$W(4)=2540(1.90)^4$

$W(4)=33101.534 MW$

c.In 2013

t=13

$W(13)=2540(1.9)^{13}=10.68\times 10^6MW$

Rachel Perez rented a car for 3 days at $40.00 per day, plus $0.20 per mile. To protect herself in case of an accident, she purc

expeople1 [14]

Answer:

$290.

Step-by-step explanation:

We have been given that Rachel Perez rented a car for 3 days at $40.00 per day.

$\text{The cost of renting a car for 3 days}=3\times \$40$

$\text{The cost of renting a car for 3 days}=\$120$

We are also told that she pays $0.20 per mile for renting the car. As she covered a total distance of 500 miles, so cost of renting car foe 500 miles will be:

$\text{Cost of renting the car for 500 miles}=500\times \$0.20$

$\text{Cost of renting the car for 500 miles}=\$100$

As Rachel purchased the collision deductible for $10.00 per day to protect herself in case of an accident, so cost of collision deductible for 3 days will be:

$\text{The cost of collision deductible for 3 days}=3\times \$10$

$\text{The cost of collision deductible for 3 days}=\$30$

She also paid $40 for gasoline to cover 500 miles, so we can find total cost to rent the car for 3 days to cover 500 miles by adding all the expenses.

$\text{The total cost to rent the car}=\$120+\$100+\$30+\$40$

$\text{The total cost to rent the car}=\$290$

Therefore, the total cost to rent the car was $290.

Plz I really need help with this problem Find the are of the shaded region

Nat2105 [25]

Answer:

$379.69 \: {ft}^{2}$

Step-by-step explanation:

Area of the shaded region = Area of the square with side 25 ft - Area of the semicircle with radius (25/2) = 12.5 ft.

$= {(25)}^{2} - \frac{1}{2} \times \pi \times {(12.5)}^{2} \\ \\ = 625 - \frac{1}{2} \times 3.14 \times 156.25 \\ \\ = 625 - 245.3125 \\ \\ = 379.6875 \: {ft}^{2} \\ \\ = 379.69 \: {ft}^{2}$
