A.) P(t) = 130t - 0.4t^4 + 1200
The population is maximum when P'(t) = 0
P'(t) = 130 - 1.6t^3 = 0
1.6t^3 = 130
t^3 = 81.25
t = ∛81.25 = 4.3 months.

Maximum population P(t)max = 130(4.3) - 0.4(4.3)^4 + 1200 = 1,622

b.) The rabbit population will disappear when P(t) = 0
P(t) = 130t - 0.4t^4 + 1200 = 0
 t ≈ 8.7 months

Answer:

150 students.

No

.20

3/10

Step-by-step explanation:

What you do for the first one is you take 1,500 and times it by 90%. You will get 1,350. You will then take the 1350 and minus it from 1500 to get 150 students.

The next one says that he drilled a hole that is 5/9 inches wide. He has a drill bit that is 5/6. Will the drill bit be big enough. No because 5/9 is .556 and 5/6 is .833.

For the next one all they want you to do is look at the fruit percentage and put it into a decimal which is .20.

The next one they want the fraction that represents 30% which is 3/10.

Which expression is equivalent to 30 (1/2x - 2) +40 (3/4y-4)? (will add pic)
bixtya [17]

Answer:

C

Step-by-step explanation:

Given

30( \frac{1}{2} x - 2) + 40( \frac{3}{4} y - 4)

Multiply each of the terms in the first parenthesis by 30 and multiply each of the terms in the second parenthesis by 40.

= 15x - 60 + 30y - 160

= 15x + 30y - 220 → C

What is the y intercept of 60x+55y=660 [with work shown]
adelina 88 [10]

Answer:

(11, 0)

Step-by-step explanation:

to find the y intercept, set y to 0.

60x + 55y = 660

60x + 55 * 0 = 660

60x = 660

60x/60 = 660/60

x = 11

y intercept is (11, 0)
