Answer:
Step-by-step explanation:
When the exponent is attached to the trig function like that, its essentially the same thing as taking the entire function to that power.
tan^2(x) = (tanx)^2
The answer would be B. (228-89) because you are trying to find the difference.
Answer:
A=2πrh
Step-by-step explanation:
A=2*22/7*4*9
=230
Answer:
5/4
Step-by-step explanation:
2 1/2=5/2
(5/2)(1/2)=5/4
Answer:
B
Step-by-step explanation:
you can use foil and the graph,
because you can see (in the graph) that the lines intersect at 1 and 4.
just use foil to help figure out which matches the slope.
something else (the normal way) is find which 2 numbers equal to the last coefficient, in this case it can be
-2 and -2, 2 and 2, 4 and 1 or -4 and -1, multiply them and if they make up the last coefficient, and added it equals the second coefficient it is correct.
