Answer:
D
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
cos(ax) reduces the period by a. So y will have a period of (2*pi)/4=pi/2
Sure what do you need help with
Answer:
slope=5/2
y intercept=2
Step-by-step explanation:
1) turn equation into slope intercept form
y=mx+b
2y=4+5x
y=
y=2+5x/2
y=5/2x+2
in y=mx+b, "m" represents the slope and "b" represents the y intercept in our equation, m is 5/2 and b is 2, hence slope=5/2 y intercept=2
Answer:
90°
Step-by-step explanation:
Angles in a triangle add up to 180°
The two angles you have add up to 90°
You need another 90° to make it 180°
