Substitute -8 for t in the expression, and now you have: h(-8) = -2[(-8) + 5]^2 + 4. Solve inside the parentheses; add -8 and 5.
h(-8) = -2[-3]^2 + 4, solve exponents next by squaring -3.
h(-8) = -2[9] + 4, multiply -2 and 9.
h(-8) = [-18] + 4, add -18 and 4.
h(-8) = -14.
59 blue jays, 68 black crows, 12 red robins, 1 cardinal....total of 140 birds
there were 59 blue jays spotted...
59/140 = x / 300...59 jays to 140 birds = x jays to 300 birds
cross multiply
(140)(x) = (300)(59)
140x = 17700
x = 17700/140
x = 126.42...rounds to 126 blue jays <==

Answer:
65 miles every 1 hour
Step-by-step explanation:
Unit rate is found once one of the units is 1. In this case we need to reduce the ratio so that it is 1 hour and we get a unit rate. We can do this by dividing both sided by 2 so that the hours are reduced to 1.
130=2
130/2=65 2/2=1
65=1
65 miles every hour

Answer:
4 1/2 days
Step-by-step explanation:
The time is given by ...
time = quantity/rate
time = (3/4 fence)/(1/6 fence/day) = (3/4)(6) days = 4 1/2 days
