The precent of voters between the ages of 18 and 29 that participated in each untied states presidential election between the years 1988 to 2016 are shown in the table. The function “p” gives the percent of voters between 18 and 29 years old that participated in the election in year “t”. a) determine whether “p” increased or decreased between 1992 and 2000

b) determine the average rate of change for “p” between 1992 and 2000

c) pick two different values of “t” so that the function has a negative average rate of change between the two values. determine the average rate of change.

d) pick two values of “t” so that the function has a positive average rate of change between the two values. determine the average rate of change.

this is false ^.^ lol

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!

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

m∠a is 90°

m∠b is 40°
