Answer:
By translating the function cos(x) 90 degrees to the right.
Step-by-step explanation:
The sine function is just the cosine function translated 90 degrees to the right. You can see the visualization below. They overlap.
If you're wondering why the diagram shows a shift in

That's just the equivalent to 90 degrees in radians.
Answer:
y = 3x + 21
Step-by-step explanation:
Use the given slope and point to substitute into the point-slope formula
Answer:
They are not equal to each other
Step-by-step explanation:
3^2 + 2^2 = C^2
9+4=C^2
13=c^2
3.6= CD
2^2 +2^2 =c^2
4+4 =c^2
8=c^2
2.8= EF
X equal what umber,and y equal what number?
Step-by-step explanation:
Replace each x in the expression/equation with the given value. Then use order of operations to simplify and solve. There are some great videos out there explaining the concept.
