Answer:
It's A.
Step-by-step explanation:
The length of the major axis is a + b where a and b are the distances from each focus to any point on the ellipse.
Answer:

Step-by-step explanation:
Slope intercept form of a line is given by:

Where
m is the slope and b is the y-intercept
Given slope is 
We can write:

Now to find b, we replace x with -3 and y with -4, given, so we have:

So, the equation is:

Now,
The standard form is given by:

So, we take x and y to left side and the constant to right side. Rearranging, we get:

The first answer choice is right.
Answer:
z = 8
Step-by-step explanation:
3/4 (z+4)=9
3/4z + 3 = 9
3/4z = 6
z = 8
Answer:
Sin(t) =
and 
Step-by-step explanation:
The secant function is the reciprocal function of the cosine function. Therefore, given that
then, if
then
.
On the other hand, if cos (t) = 1/2 ⇒ t = ±
Then, the sin(
) =
