Answer:
x =15 + 30n
Step-by-step explanation:
8cos(12x)+4=-4
Subtract 4 from each side
8cos(12x)+4-4=-4-4
8cos(12x)=-8
Divide by 8
8/8cos(12x)=-8/8
cos(12x) = -1
Take the arccos on each side
arccos(cos(12x)) = arccos(-1)
12x = 180 degrees
But we can go around in a circle of 360 and get the same result
12 x = 180+360n where n is an integer
Divide each side by 12
x = 180/12 +360n/12
x =15 + 30n
Answer:
A
Step-by-step explanation:
distributive property
Answer:
The y-intercept of the function represented in the graph will be: (0, 2)
The graph is also attached.
Step-by-step explanation:
Given the function
the y-intercept of the function can be determined by setting x=0 and solving for y.
so
Thus, the y-intercept of the function represented in the graph will be: (0, 2)
The graph is also attached.
Write the equation of the circle with center (3, 2) and radius r = 7. Use the ^ key for the exponents. Write your answer as the example:
(x - 4)^2+(y+8)^2=25
Through any two points there is exactly one line
