Answer:
D) -122
Step-by-step explanation:
Given:
We need to find f(-4).
Now by substituting the value of x =-4 in above equation we get;
By using PEDMAS we will solve for exponential function first we get;
Now we know that
So we get;
Now using PEDMAS we will solve division.
Now using PEDMAS we solve multiplication.
Finally by subtraction we get;
Step-by-step explanation:
line a is perpendicular to B.
if the slope of line A is -3/4 what is the line of B

750×0.10=75
Answer:
14
Step-by-step explanation:
To find x, you will need to use sine. If you want to find y, use cosine:
sin 45 = x / 14 sqrt(2)
x = 14
(Since this is a 45 45 90 special triangle, x and y have the same length)
Since I talk about special triangles, 45 45 90 triangles are very simple:
To find the other two side lengths, just divide the hypotenuse by sqrt 2
14 sqrt(2) / sqrt(2) = 14
So both ways will still lead to 14
