Apply the laws of exponents, calculate the result and express the result in scientific notation, and as a decimal: ((4.1·103)(2.8·10−7))/(3.1·10−5) the result in scientific notation is_ *10^_. the result as a decimal is_.

We are given

We can move like terms altogether

now, we can use property of exponent

We can use another exponent property

so, we get

So, the result in scientific notation is

..........Answer

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
