Mathematics
1 answer:

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.

The length of a rectangle is 4cm longer than the width, and the perimeter is at least 48cm. What are the smallest possible dimen
jenyasd209 [6]
So since the length is 4+w.  Then the perimeter 2(4+w) + 2w >= 48.  
so, 8+2w+2w>=48.
8+4w>=48
4w>=40
w>=10
so, the width must be at least 10.  And the smallest dimensions can be 10 x 14.

Four less than nine times a number is one hundred twenty-two. Find the original number.
Tasya [4]

Answer:

The number is 14

Step-by-step explanation:

Denote the original number by z. The expression "Four less than nine times a number is one hundred twenty-two" can be rewritten in an equation.

Our number is z, then the left hand side of the equation is 9z-4.

The right side of the equation is 122. Then the complete equation is 9z-4=122. Add 4 in both sides to get 9z=122+4=126. Now, divide by 9 in both sides to get z=\frac{126}{9}=14
