<span>He relationship between rectangular and rotational coordinates can be represented by the vector equation:
r = xi +yj = rcos(theta)i+rsin(theta)j
What values in radians makes
x minimum
y maximum
and x = -y
Ans : x minimum = -r when theta = 180 degrees + any multiple of 360 degrees
y minimum = -r when theta = 270 degrees + any multiple of 360 degrees
x = -y when theta = 135 degrees + any multiple of 180 degrees.</span>
Answer: 5.43
Step-by-step explanation:
The final bill is $544
The parts is a one time bill of $265
The labor is $48 per hour, and lets call the hours 'h'
So we can make the equation as:
544 = 265 + 48h
Subtract 265 n both sides
279 = 48h
Divide by 48 on both sides
h = <span>5.8125
So the number of hours of labor spent repairing the car is </span><span>5.8125.</span>
Hello from MrBillDoesMath!
Answer: x = 10 for 4x - 8 = 32
x = -5 for 2(x-5) = -20
Discussion:
------------------------------
4x - 8 = 32 (*)
Add 8 to both sides:
4x - 8 + 8 = 32 + 8 =>
4x = 40 =>
x = 10
-----------------------------------------------
2(x-5) = 2x - 2(5) =>
2x - 10 = -20 (**)
Add 10 to each side of (**):
2x - 10 + 10 = -20 + 10 =>
2x = -10
x = -5
Thank you,
MrB
