What does r mean. if r means multiply blank than 3*4 = 12
a. 1^5 = 1 × 1 × 1 × 1 × 1 = 1
b. 2 × 2 × 2 × 2 × 2 = 2^5 = 32
c. 20^3 = 20 × 20 × 20 = 8.000
d. 7 × 7 × 7 × 7 = 7^4 = 2.401
Answer:
C.)
Step-by-step explanation:
The graph is positive this time, so right away you can eliminate A and B.
If y=2x, the graph would be much steeper so the answer is C.) you can also check by graphing it in desmos.
Using the fact that cos is 2π-periodic, we have
That is, for any and integer .
We get 2 solutions in the interval [0, 2π] for and ,
Answer:
Step-by-step explanation:
we can write -9 instead of x and y=1 instead of 1
so we write solution again
-9a+1b=-31
-9a-1b=-41
-18a=-72
a=4
we should write 4 instead of a
-9(4)+1b=-31
-36+b=-31
b=5
a=4
