1. 2700 degrees. 450 rotations in on minute is 450(360) degrees per minute. If you divide this by 60 you get 2700.
2. 180 degrees. 4.3 rotations per minute is 4.3 times 360 degrees per minute. Multiply that times 5, and divide the answer by 360 and you get 21.5, which means he is 180 degrees from his starting point.
Answer:
y= 
Step-by-step explanation:
x₁ y₁ m= slope
(2, -4) point-slope equation: y - y₁ = m( x - x₁)
y-(-4) = 
( x - 2)
y + 4 = 
- 
y = - - 
y = - 
Answer:
(-3,5)
Step-by-step explanation:
First, you want to find out how many feet in a yard
3ft=1yd
so you do 21/3 to get your yard, and the answer is 7 yard
17 yard is greater than 7 yard so 17 is the answer
The current is doubled. Ohm's law states that V = IR, therefore, if the voltage is doubled, aka 1.5 to 3V, than assuming resistance stays constant, the current must double.
