We have to find the period of the parent cosine function and the period of the function showed on the graph.
Period = 2π / B, where B is the coefficient of x - term.
1. For the function: y = cos x, B = 1
Period = 2 π / 1 = 2 π = 360°.
2. For the graphed function ( from the picture ):
Period = 6 π = 1,080°
Answer:
1/2
Step-by-step explanation:
12 goes into itself and 24 2 times. SO it is 1/2
Answer:
C
Step-by-step explanation:
The absolute value function always gives a positive result, that is
| - a | = | a | = a
Given
| - 12 | - | - 3 |
= 12 - 3
= 9 → C
Luis is 10 yrs old
so his dad is 40 yrs old
so his grand father is 60 yrs old
which adds up to 110
so the answer is luis father is 40
If you meant 3x-12=9, the answer is x= 7
