Please, in the future, post just one problem at a time.
Looking at Problem #1: The line intersects the y-axis at (0,-3) and intersects the x-axis at (1,-1). At least, this is what I see; your graph is small.
-3-[-1]
The slope of that line is then m = rise / run = ------------ = +2.
0 - 1
[change in y]
Slope = m = rise / run = --------------------
[change in x]
Answer: -7cos(x)
Step-by-step explanation:
d/dx (f(x))= -7cos(x)
Answer:
B.
the complementary angles form a right angle with the shared ray
Answer:
I'm going to write both of these because maybe you have a fill in the blank question. I don't know.
Simplify:
Step-by-step explanation:
is the equation of a circle with center (h,k) and radius r.
You are given (h,k)=(4,5) because that is the center.
You are given r=9 because it says radius 9.
Let's plug this in.
Simplify:
