One more and my little friend is done with school loll Look at the following numbers: –7, 0, 7, 14 Which pair of numbers has a sum of 0?
Which pair of numbers has a sum of 0?

0, 7
–7, 7
7, 14
–7, 14

-7 and 7

Step-by-step explanation:

-7+7=0

because they are opposite numbers

Step-by-step explanation:

-7+7= 0

it is hence -7 and 7

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

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
