Use the graph to determine the domain and range of the relation, and whether the relation is a function.

a. Domain: {xl-8, 8}; Range: all real numbers; No, it is not a function.
b. Domain: {x-8 SX s 8}; Range: all real numbers; Yes, it is a function.
c. Domain: {x| -8 < X < 8}; Range: all real numbers; No, it is not a function.
d. Domain: {x| -8 < X 8}; Range: {yl -12 sx s 12); Yes, it is a function.

this was already solved by me with a different person. if you look it up in the search bar at the top of the page, you will get the answer.

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
