The function shown below was created to track the different intervals of speed that an automobile travels over a period of 28 se
Ksenya-84 [330]

Answer:

1. The car is slowing down at a rate of 2.5mph/s

2. The greatest acceleration is 10 mph/s.

3. In the interval 4s to 16s the speed remains constant and has magnitude 25 mph.

Step-by-step explanation:

1. The deceleration of the car is from 16 seconds to 24 seconds is the slope m of the graph from 16 to 24:

m=\dfrac{\Delta speed }{\Delta time } = \dfrac{5-25}{24-16} =-2.5mph/s

the negative sign indicates that it is deceleration.

2. The automobile experiences the greatest change in speed when the slope is greatest because that is when acceleration/deceleration is greatest.

From the graph we see that the greatest slope of the graph is between 28 and 24 seconds. The acceleration the interval is the slope m:

m= \dfrac{45-5}{28-24}= 10mph/s

3. The automobile experiences no acceleration in the interval 4 s to 16 s—that's the graph is flat.

The speed of the automobile in that interval, as we see from the graph, is 25 mph.

A company sells a mix of peanuts and cashews. For every 3 ounces of peanuts, there are 2 ounces of cashews. A batch has 60 ounce
shtirl [24]

Answer:

Proportion states that the two ratios or fraction are equal.

As per the given statement: For every 3 ounces of peanuts, there are 2 ounces of cashews. A batch has 60 ounces of peanuts.

Let x be the ounces of cashew will a batch have.

then by definition of proportion, we have;

\frac{3}{2} = \frac{60}{x}

By cross multiply we have;

3x = 120

Divide by 3 on both sides we get;

x = 40

therefore, 40 ounces of cashews will a batch have for every 60 ounces of peanuts.

Solve for x<br> -x + 4=22
bekas [8.4K]

Answer: x = −18

Step-by-step explanation:

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-4' to each side of the equation.

4 + -4 + -1x = 22 + -4

Combine like terms: 4 + -4 = 0

0 + -1x = 22 + -4

-1x = 22 + -4

Combine like terms: 22 + -4 = 18

-1x = 18

Divide each side by '-1'.

x = -18

Simplifying

x = -18
