The number of bacteria (b) in a batch of refrigerated food is given by the function b(t) = 20t2 − 70t + 300, where t is the temp

Setler79 [48]

If the number of bacteria $b(t)$ is a function only of temperature $t$ , and the temperature $t(h)$ is a function only of time in hours $h$ , then

$b(t(h))=b(2h+3)=20(2h+3)^4-70(2h+3)+300$
$b(t(h))=320h^4+1920h^3+4320h^2+4180h+1710$

The perimeter of a rectangular field is 322 m.

Bond [772]

Answer:

Step-by-step explanation:

322 = 2(86) + 2w

322 = 172 + 2w

322-172 = 172 +2w -172

150 = 2w

150/2 = 2w/2

w=75

A boat takes 8 hours to go 6 miles upstream and come back to the starting point. If the speed of the boat is 4 miles per hour in

ad-work [718]

Let the speed of the water current be v.

total travel time = time to go upstream + time to return downstream to the starting point

Hence, 8 = time in hours = 6 / (4-v) + 6 / (4 +v) = 6*8/(16-v^2)

Hence, 16 - v^2 = 6, or v^2 = 10 or v = √10 miles / hour
