It is 3 groups. Because the max of 3/4 is 9/4
Answer:
a) 3 inch pulley: 11,309.7 radians/min
6) 6 inch pulley: 5654.7 radians/min
b) 900 RPM (revolutions per minute)
Step-by-step explanation:
Hi!
When a pulley wirh radius R rotantes an angle θ, the arc length travelled by a point on its rim is Rθ. Then the tangential speed V is related to angular speed ω as:

When you connect two pulleys with a belt, if the belt doesn't slip, each point of the belt has the same speed as each point in the rim of both pulleys: Then, both pulleys have the same tangential speed:


We need to convert RPM to radias per minute. One revolution is 2π radians, then:


The saw rotates with the same angular speed as the 6 inch pulley: 900RPM
Answer:
Step-by-step explanation:
1). y = - 4x + 7
Reflected across what????
if x-axis, then y ⇒ - y
So the answer would be <em>y = 4x - 7</em>
2). <em>y = 2x - 14</em>
3). <em>y = 2x - 8</em>
4). <em>y = 12x + 9</em>

Answer:
Answer choice A is the correct answer
Step-by-step explanation:
** Before you start: If anything that is < or > you shouldn't fill in the plot.
If it has ≤ or ≥then you need to fill in the plot.**
Terminology:
(>) : Greater than (Don't fill in)
(<): Less than (Don't fill in)
(≤) : Less than or equal to (Fill in)
(≥) : Greater than or equal to (Fill in)
In this case, the answer choices C and D are wrong automatically.
Your Inequality:
11g + 5 ≤ 49
Subtract 5 both sides
11g ≤ 49-5
11g ≤ 44
Divide 44 by 11
g ≤ 4
Find an answer choice that has a number greater than 4 but has a filled-in circle/plot.
Answer choice A is the correct answer
