A population of 30 sasquatch is released in a wildlife region. The population doubles each year for 4 years. What is the population after 4 years?

480 sasquatch

Step-by-step explanation:

Year one: 30 x 2 = 60 sasquatch

Year two: 60 x 2 = 120 sasquatch

Year three: 120 x 2 = 240 sasquatch

Year four: 240 x 2 = 480 sasquatch

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
