alfredo bought a fishing pole for 60 off it's original price of $97 if the tax was 4% how much did alfredo pay for the fishing p

Agata [3.3K]

Answer:

$40.4

Step-by-step explanation:

The regular price of the fishing rod is $97

There is a 60% discount from that price.

The discount is equal to 60% of $97 which is equal to .60 * $97 which is equal to $58.2

Discount is like a markdown, so subtract $58.2 from the price of the item before the change to get $97 - $58.2 = $38.8

This is the price of the item before tax is applied.

Now you apply the sales tax of 4%.

4% of $38.8 is equal to .04 * $38.8 which is equal to $1.552

Tax is like a markup, so add $1.552 to the price of the item before tax was applied to get a selling price of $38.8 + $1.552 which is equal to $40.352

Round it up and the answer is $40.4

For which intervals below is the average rate of change less than or equal to zero?

77julia77 [94]

Answer:

Intervals A and C only

Step-by-step explanation:

we know that

The graph show a vertical parabola open upward

The vertex represent a minimum

The vertex is the point (-6,-9)

Remember that the vertex is a turning point

That means

In the interval (-∞,-6) the function is decreasing (rate of change is negative)

In the interval (-6,∞) the function is increasing (rate of change is positive)

therefore

<u><em>Verify each case</em></u>

Interval A) A -13 ≤ x ≤ -10

Belong to the decreasing interval, so the rate of change is negative

Interval B) -5 ≤ x ≤ 0

Find the rate of change

the average rate of change is equal to

$\frac{f(b)-f(a)}{b-a}$

In this problem we have

$a=-5$

$b=0$

$f(a)=f(-5)=9$

$f(b)=f(0)=0$

Substitute

$\frac{9-0}{0+5}=9/5$

Interval B the rate of change is positive

Interval C) --10 ≤ x ≤ -2

Find the rate of change

the average rate of change is equal to

$\frac{f(b)-f(a)}{b-a}$

In this problem we have

$a=-10$

$b=-2$

$f(a)=f(-10)=-5$

$f(b)=f(-2)=-5$

Substitute

$\frac{-5+5}{-2+10}=0$

Interval C the rate of change is zero

therefore

Intervals A and C only
