Answer:
No, some of the ordered pair in this graph have the same first element.
Step-by-step explanation:
The relation of a function is that it expresses a dependence of one element on another. There is a one to one relation, which means that one point can not be used more then once.
Some ordered pairs in this graph have the same first element and are used more then once. So this graph can not represent a function.
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
D. 0.75 is the correct answer
explanation- 2 out of the 8 tiles are not blue A. so 6 out of 8 tiles would round equal 75% chance of not getting a blue A tile

Answer:
C)
Step-by-step explanation:
If you divide 8:2 by two you get 4:1 which is the equivilant ratio.
Hope this helps.
Answer:
<h2>D. g(x) = (x - 4)²</h2>
Step-by-step explanation:
f(x) + n - shift the graph n units up
f(x) - n - shift the graph n units down
f(x - n) - shift the graph n units to the right
f(x + n) - shift the graph n units to the left
=========================================
The graph of f(x) shifted by 4 units to the right. Therefore, the equation g(x) is:
g(x) = f(x - 4) = (x -4)²
