Answer:
a. 3/4 inches per minute
b. -1 1/8 inches per minute
c. B is fastest; 1 1/8 is more than 3/4
Step-by-step explanation:
A <em>change</em> is a <em>difference</em>. A <em>rate of change</em> is <em>one difference divided by another</em>, usually the change in y-value divided by the change in x-value.
__
<h3>a.</h3>
The change in elevation is the difference between the elevation at the end of the period (6 inches) and the elevation at the beginning of the period (3 inches). The change in time period is the difference between the end time (8 min) and the beginning time (4 min).
change in elevation per minute = (6 -3 inches)/(8 -4 min)
= (3 inches)/(4 min) = 3/4 inches/minute
__
<h3>b.</h3>
Similarly, ...
change in elevation per minute = (3 -7 1/2 inches)/(18 -14 min)
= (-4 1/2 inches)/(4 min) = -1 1/8 inches/minute
__
<h3>c.</h3>
We know that 3/4 is more than -1 1/8, but when we talk about the "fastest rate of change", we're generally interested in the magnitude--the value without the sign. That means we understand a rate of change of -1 1/8 inches per minute to be "faster" than a rate of change of 3/4 inches per minute.
The rate of change from Part B is fastest. 1 1/8 inches per minute is more than 3/4 inches per minute.
Answer:
OMG I KNOW THE ANSWER!!!!!!!!
Step-by-step explanation:
its b.
From the equation, you can see that (3,-2) is the center of the circle (the terms are 0 for those x,y values). The mentioned point has the same y value as the center. That's good news, because it tells us that the tangent line is exactly vertical. The x coordinate is given as x=8. Vertical lines have an equation of x=... so x=8 is the right answer.
Answer:
D would be the answer
Step-by-step explanation:
Mia’s first error was " she forgot to multiply π by (17.5)²(47) "
Step-by-step explanation:
The formula of the volume of a cylinder is V = π r² h, where
- r is the radius of the base of the cylinder
- h is the height of the cylinder
∵ The diameter of the base of the cylinder is 35 meters
∵ The radius = × diameter
∴ The radius = × 35 = 17.5 meters
∴ r = 17.5
∵ The height of the cylinder = 47 meters
∴ h = 47
- Substitute r and h in the formula of the volume
∴ V = π (17.5)²(47)
∵ Mai's first step is V = (17.5)²(47)
- She forgot to put π
∴ Her first error is she forgot to multiply π by (17.5)²(47)
Mia’s first error was " she forgot to multiply π by (17.5)²(47) "
