one light year is equal to 9 ,460,600,000,000 kilmeters . what is this distance represented in scientific notation

9.4606x10^12 kilometers

Step-by-step explanation:

The scientific notation is numbers is exponents with a base of 10. As this number is 9.4606 trillion, we need to use 1 trillion as 10^12. Then we multiply by 9.4606 to get 9.4606x10^12 km. Hope it helps!

answer: need picture of problem

step-by-step explanation:

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
