It’s easy the answer is 384
Answer:
a) P(t) = 330 
b)P(t) →population after t years.
t →number of years.
c) Number of deer after five years = 556
Step-by-step explanation:
a) The population increasing at an annual rate of 11%, means the population is being multiplied by 1.11 each year.
So, we can use the formula
P(t) = P 
P(t) = 330 
P(t) = 330 
b) In this model
P(t) → population after t years
P → present population
r → annual increasing rate
c) Number of population after 5 years is,
P(5) = 330 
= 556
Number of deer after 5 years = 556
Answer:2(xy-7)= -20
Step-by-step explanation:
Plug in -1 for x and 3 for 3, as the question says that x and y represent those values.
2(xy-7) = ?
2((-1)(3) - 7) = ?
2(-3-7)=?
2(-10)
-20
2(xy - 7) = -20
F1 . . . 100% of it = 900N is in the +x direction.
F2 . . . 70.7% of it (cos45°, 530.3N) is in the +x direction,
and 70.7% of it (sin45°, 530.3N) is in the +y direction.
F3 . . . 80% of it (520N) is in the -x direction,
and 60% of it (390N) is in the +y direction.
Total x-component: 900 + 530.3 - 520 = 1,950.3 N
Total y-component: 530.3 + 390 = 920.3 N
Magnitude of the resultant = √ (x² + y²)
= √(1950.3² + 920.3²)
= √4,650,070.09
= 2,156.4 N .
Angle of the resultant, measured counterclockwise
from the +x axis, is
tan⁻¹ (y / x)
= tan⁻¹ (920.3 / 1950.3)
= tan⁻¹ (0.4719)
= about 25.3° .
