Answer:
Use the form asin(bx−c)+d to find the variables used to find the amplitude, period, phase shift, and vertical shift.
a=−4
b=2
c=7
d=3
Find the amplitude |a| .
Amplitude: 4
Find the period using the formula 2 / |b|.
Find the phase shift using the formula c / b .
Phase Shift: 7/2
List the properties of the trigonometric function.
Amplitude: 4
Period:
Phase Shift: 7/2 (7/2 to the right)
Vertical Shift: 3
Step-by-step explanation:
Answer:
130
Step-by-step explanation:
The intercepted arc of the angle with measure 50 is 100
x + x + 100 = 360
2x + 100 = 360
2x = 260
x = 130
Answer:
the pic is not clear. what is it asking?
Step-by-step explanation:
Use the Midpoint formula:
( (x1 + x2) / 2 , (y1 +y2) / 2 )
( ((-2 + (-4)) /2, (5-9)/2 )
Midpoint: (-3, 7)
