It would be -4, and 9.2 because they sign is saying that x is less than or equal too 11.
The group lose 8.8 pounds per day. For a detailed calculation, please refer to the attachment.
Answer: Assuming the riders starts at the position (20, 0) on the x-axis, the exact position of the rider will be (20cos75, 20sin75) or about (5.18, 19.32).
The angle for 5pi/12 radians is 75 degrees. Therefore, to find the position we can use the sine and cosine of 75 to find the x and y value of the coordinate.
For the y-value, we can write and solve:
sin75 = x/20
For the x-value, we can write and solve:
cos75 = x/20
Answer:
5.23
Step-by-step explanation:
It would be 8 because 8+4=12
