Answer:

Step-by-step explanation:
we know that
The volume of a trough is equal to

where
B is the area of equilateral triangle
L is the length of a trough
step 1
Find the area of equilateral triangle B
The area of a equilateral triangle applying the law of sines is equal to

where


substitute


step 2
Find the volume of a trough

we have


substitute


The intersection with the y axis occurs when x = 0.
We have then:
For f (x):
For g (x):
We can observe in the graph that when x = 0, the value of the function cuts to the y axis in y = -3
For h (x):

Therefore, the graph with the intersection with the largest y axis is h (x)
Answer:
the greatest y-intercept is for:
C. h(x)
There is no solution to this system of linear equations
In this case, the vector is passing through a right angle as shown with the little square on the left side. (all right angles equal 90 degrees) so you would simply subtract 64 from 90. (90 - 64 = 26) so x equals 26 degrees.
