we are given
A cd has diameter of 120 millimeters
so, d=120mm
so, firstly, we will find radius
we can plug it
we know that
1mm=0.001m
so, we get
the angular speed is about 206 rpm
we know that
1 revolution =2pi radians
so, we get
now, we can change it into seconds
1 min =60 seconds
so, we get
now, we can find linear speed(v)
we can use formula
v=w*r
so, we can plug values
and we get
so, linear speed is 1.257 m/sec............Answer
Answer:
The water dispenser's capacity in liters is 20liters
Explanation:
Given:
A water dispenser capacity = 20,000milliliters
To find
the capacity of the water dispenser in liters
To determine the capacity in liters, we will convert the capacity in ml to liters using the conversion:
1000ml = 1 liter
let the capacity of the water dispenser in Liters = y
The water dispenser's capacity in liters is 20liters

Answer:
y - 8 = -2(x - 9)
Step-by-step explanation:
Given the slope, m = -2, and the point, (9, 8):
Let (x₁, y₁) = (9, 8)
slope (<em>m </em>) = -2
We can substitute these values into the following <u>point-slope form</u>:
y - y₁ = m(x - x₁)
y - 8 = -2(x - 9) ⇒ This is the point-slope form.
Part A
4 < 5 < 9 is given to us. Apply the square root to each term to end up with this inequality: sqrt(4) < sqrt(5) < sqrt(9)
So sqrt(5) is between <u>sqrt(4)</u> and <u>sqrt(9)</u>
-------------------
Part B
Simplify those two mentioned square roots
sqrt(4) = sqrt(2^2) = 2
sqrt(9) = sqrt(3^2) = 3
Therefore, sqrt(5) is also between <u>2</u> and <u>3</u>
We can see this through using a calculator: sqrt(5) = 2.23607 approximately
-----------------
Part C
We can now say:
2 < sqrt(5) < 3
Multiply all three sides by 6
6*2 < 6*sqrt(5) < 6*3
So the expression 6*sqrt(5) is between <u>6 x 2</u> and <u>6 x 3</u>
Sure enough, a calculator confirms this
6*sqrt(5) = 13.416408
since 6*2 = 12 and 6*3 = 18. We see that 13.416 is between 12 and 18.
