Answer: (4)
Step-by-step explanation:
Consider for each point how far it is above (or below) the horizontal line y=2. Then plot its image the same distance below (or above) that line.
Answer:
The measure of the angles are 55° and 35°
Step-by-step explanation:
Sum of two angles that are complement of each other are 90.
The angles are A and B, so we can write:
A + B = 90
Also,
The difference is 20. Let A be the greater of them, so we can write equation 2 as:
A - B = 20
Now, we add up both equations, eliminate B and solve for A first:
A + B = 90
A - B = 20
---------------
2A = 90 + 20
2A = 110
A = 110/2
A = 55
And now the measure of B:
A + B = 90
55 + B = 90
B = 90 - 55
B = 35
Answer:
Step-by-step explanation:
The max value of the sine function is 1.
If we multiply it by 2, we get 2 sin x, whose max. value is 2.
If we multiply the sine function by -2, the max value of this functin is still 2.
