Suppose the function h(t) gives the heart rate of a cyclist at various points in time during a 50 mile bike ride. What is the domain for this function? (Assume the cyclist completed the 50 mile ride in 150 minutes.)

e.

step-by-step explanation:

because there are always 10 numbers in a phone number.

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)

b, i believe, but not sure.

answer: they are supplementary angles

step-by-step explanation: 161+19=180. supplementary angles equal 180 degrees
