Find all angles θ between 0° and 180° satisfying the given equation. round your answer to one decimal place. (enter your answers
as a comma-separated list.) tan(θ) = −21
1 answer:
Alright, lets get started.
tan Ф = -21
Using inverse function,
Ф =
Using calculator, we could find ta inverse value
Ф = - 87.3°
But as per given question, angle must lie between 0 and 180 degrees.
Means angle should present in first or second quadrant.
As tan value is given negative (-21), means angle will be in second quadrant.
If we add 180 degrees in our angle, the angle will lie in second quadrant. (refer the diagram)
Ф = - 87.27 + 180 = 92.73°
Ф = 92.73° : Answer

Answer:
a.
b.
c.13.3 months
Step-by-step explanation:
a.-Given the first term at is 6 and the second term at
is 32.
-Let's take rabbit population as a function of time to be
where y is the population at time x and a the initial population at
#We substitute our values to calculate the value of the constant b:
#Replace b in the population function:
Hence, the regression for the rabbit population as a function of time x is
b. The exponential function in terms of base is usually expressed as:
Where:
-is the initial population at
-is the population at time t.
is the exponential growth constant.
the exponent
Our function in terms of base exponent is rewritten as:
#Substitute with actual figures to solve for t:
Hence, the regression equation in terms of base e is
c. We substitute y with any number higher than 10,000 to estimate the time for the rabbits to exceed 10,000.
-We know that
Therefore we calculate t as(take y=10001):
Hence, it takes approximately 13.3 months for the population to exceed 10000
