Answer:
60
Step-by-step explanation:
b = the hypotenuse of a right angle triangle
a = the adjacent side.
R is being defined by the cosine
cos(R) = adjacent / hypotenuse
adjacent = 16* sqrt(2)
hypotenuse = 32*sqrt(2)
Cos(R) = 16*sqrt(2) / 32*sqrt(2) sqrt(2) cancels.
cos(R) = 1/2
R = cos-1(1/2)
R = 60 degrees.
Part A.
In this part we have to find the increasing interval .
Increasing interval is that interval where graph goes up. And from the graph we can say that the graph goes up in the interval

And that's the increasing interval .
Part B.
Correct option is B
x and y intercepts
x intercept is the point where graph touches the x axis. And the graph touches the x axis at x=-1 and 1 .
So the x intercepts are

y intercepts are the point, where the graph touches or crosses the y axis.
Therefore the y intercept is (0,1)
So the correct option is D .
Answer:
cos210=cos(180+30)=−cos30=−√32 . sin210=sin(180+30)=−sin30=−12 . 3(cos210+isin210) =3(−√32)+3i(−12). −(32)√3−(32)i. My favourite way of seeing that sin30=12 and cos30=√32 is ...
Step-by-step explanation:
But that's what I say personally
So it would be 600 miles you can drive within the limit of $250 and that would be $160 for the 5 day trip with $32 a day and 90 divided by $0.15 is 600 miles. 600 Miles is the answer.
Check the picture below.
notice the midpoint of the diameter segment, is just 1,9.
also, recall the radius is half the diameter, notice how long the radius is, just 4 units.
