Answer:
I have already answered this in your last question:)
Answer: 80
Step-by-step explanation:
Sin x = cos (90-x)
Like sin 30 = cos (90-30) =cos 60
So
90-x=90-80
Then
X=80
Verify your solution by finding the sum of the angles of sin and cos, it will be 90
Answer:
Step-by-step explanation:
2a^-a-13=2
Subtract 2 from both sides :
2a^2-a-13=2=2-2
2a^2-a-15=0
Factor left side of the equation :
(2a+5) (a-3)=0
Set factors equal to 0 :
2a+5=0 or a-3=0
a=-5/2 or a=3
For this case, the first thing we will do is rewrite the function.
We have then:
p (t) = (39.87) * (1.016) ^ t
Part A:
For t = 10 we have:
p (10) = (39.87) * (1.016) ^ 10
p (10) = 46.72865869
Answer:
The population of this group for the year 2010 is:
p (10) = 46.72865869
Part B:
We must calculate in this case the following expression:
(1,016) ^ t
Substituting for t = 10
(1,016) ^ 10 = 1.17202555
Answer:
the instantaneous rate of change of the population when tequals 10 is:
1.17202555
Sorry if these are not correct, but this is what i came up with
1. -36 is less
