Answers:
B = 50
a = 10.9
c = 17.0
================================================
Explanation:
This is a right triangle, so the acute angles are complementary, meaning they add to 90
B+40 = 90
B+40-40 = 90-40
B = 50
Also, because this is a right triangle, we can use trig ratios to compute the missing sides
tan(angle) = opposite/adjacent
tan(40) = a/13
a = 13*tan(40)
a = 10.908
a = 10.9
cos(angle) = adjacent/hypotenuse
cos(40) = 13/c
c*cos(40) = 13
c = 13/cos(40)
c = 17.0
note: make sure your calculator is in degree mode
Answer:
Step-by-step explanation:
The given function is .
The domain refers to all values of x for which this function is defined.
Recall that: the domain of 
is 
And we know is the reciprocal of .
Therefore the complement of the domain of which is ![(-\infty,-1]\cup [1,+\infty)](https://tex.z-dn.net/?f=%28-%5Cinfty%2C-1%5D%5Ccup%20%5B1%2C%2B%5Cinfty%29)
is the domain of
Answer:
The answer is 36
Step-by-step explanation:
To find the volume you:
Answer:
Step-by-step explanation:
WE are given that 
. Then, to now the first for terms, we must replace n by 1,2,3,4 respectively. Then
Note that as n increase, 
gets closer to 0. So, the limit of this sequence is 0.
