Option third "words per minute, because the independent quantity is the minutes" is the correct choice.
<h3>What is the rate of change?</h3>
It is defined as the change in values of a dependent variable with respect to the independent variables.
We have a statement:
Which of the following is the most appropriate unit to describe the rate at which a person reads?
As we know the rate of change is the ratio of change in y to change in x.
y is the dependent quantity and x is the independent quantity.
Rate of change = change in y/change in x
Rate at which a person reads = words/minute
Word is the dependent quantity and minute is the independent quantity.
Thus, option third "words per minute, because the independent quantity is the minutes" is the correct choice.

Answer:
Step-by-step explanation:
Since the outdoor ice skating arena is in the shape of a circle, we would determine its area by applying the formula for determining the area of a circle which is expressed as
Area = πr²
Where
π is a constant whose value is 3.14
r represents the radius of the circle
From the information given,
Diameter = 42 feet
Radius = diameter/2 = 42/2 = 21 feet
Therefore,
Area = 3.14 × 21² = 1384.74 square feet
Rounding up to the nearest whole number, area of the outdoor ice skating arena would be 1385 square feet
Answer:
x=1, y=-5
Step-by-step explanation:
4(1)+2y=-6
2y=-10
y=-5
or
-3x-2(-5)=7
-3x=-3
x=1
Hope this helps!
Answer:
x-intercepts: (2, 0) and (−5, 0)
y-intercept: (0, −10)
Step-by-step explanation:
y = x^2 + 3x − 10
y-intercept when x = 0 so y = -10, so y-intercept : (0, -10))
x-intercept when y = 0 so
x^2 + 3x − 10 = 0
(x +5)(x - 2) = 0
x + 5 = 0; x = -5
x - 2 = 0; x = 2
So x-intercepts: (-5, 0) and (2,0)

There is a linear relationship between height and volume in this example. With a constant radius value for this table, the volume is 4 times the size of the height of the cylinder.
