Answer:
Amount left for gift C = dollars
Step-by-step explanation:
Given that:
Amount Cora have to spent on gifts = $20
Amount spent on gift A = dollars
Amount spent on gift B = dollars
Amount spent on gift C = x
Total amount = Gift A + Gift B + Gift C
20 =
20 =
Dividing both sides by 20
Hence,
Amount left for gift C = dollars
Answer:
Step-by-step explanation:
1)
Altitude = 2
Period = 2pi/(1/2) = 4pi
(since 1/2 is coefficient of x)
Altitude interval = [-4,0]
Domain interval = set of all real numbers
Phase shift = 0
Vertical shift = 2 down
2) y=-4sin(2x+pi/2)-2
Altitude = 4
Period = 2pi/(2) = pi
(since 2 is coefficient of x)
Altitude interval = [-6,2]
Domain interval = set of all real numbers
Phase shift = pi/2
Vertical shift = 2 down
Answer:
A. 16.86 square inches
Step-by-step explanation:
Area of Circle = , where r = radius.
Area of Rectangle = , where l = length and w = width.
We are given the radius of the circle as 1, and we use π as 3.14
Next, we find the area of the rectangle.
Lastly, we subtract 3.14 from 20.
Therefore, the answer is A. 16.86 square inches.
