Answers

Sometimes I find it easier to let a calculator evaluate the function for me. The average rate of change is the change in output value divided by the change in input value. That is
.. average rate of change = (f(9) -f(2))/(9 -2)
For this function, this evaluates to
.. average rate of change = (25 -(-3))/(9 -2) = 28/7 = 4

_____
The graph shows the two points of interest connected by a line of slope 4, verifying our value for the average rate of change.

Final answer:

The average rate of change of the function h(x) = x² - 7x +7 over the interval 2 ≤ x ≤ 9 is 4.

Explanation:

The average rate of change for a function is determined by the difference in y values divided by the difference in x values over a specified interval. In this case, the function is h(x) = x² - 7x + 7, and the interval is 2 ≤ x ≤ 9. First, we calculate h(2) and h(9) for the y values.

h(2) = (2)² - 7(2) + 7 = 4 - 14 + 7 = -3

h(9) = (9)² - 7(9) + 7 = 81 - 63 + 7 = 25
Then, apply the formula for average rate of change which is (h(9) - h(2)) / (9 - 2).

(25 - (-3)) / (9 - 2) = 28 / 7 = 4

A bag contains 20 marbles: 12 red, 4 blue, 3 yellow, and 1 green. Arielle takes out 2 marbles. What is the probability that they are both blue?

Answers

Total number of marbles in the bag =20

Number of blue marbles =4

Now we just want two blue marbles out of four.

Probability of taking out first marble which is blue =4/20

Now after we took out one blue marble , number of blue marbles left are 3.

Probability of taking out second marble which is blue =3/20

Total probability = 4/20 *3/20 = 12/400

So probability of taking out two blue marbles is 0.03 or 12/400.

a varies directly as b and inversely as the square of c. If a = 197 when b = 5 and c = 5, find a if b = 3 and c = 3

Answers

Final answer:

The value of 'a' is found to be approximately 328.33 when b = 3 and c = 3, using the constant of proportionality obtained from the given values a = 197 when b = 5 and c = 5.

Explanation:

When a quantity varies directly as another quantity and inversely as the square of a third quantity, we can express this relationship with the following equation:

a = k x (b / c2)

where k is the constant of proportionality. Given that a = 197 when b = 5 and c = 5, we can solve for k:

197 = k x (5 / 52)

197 = k x (5 / 25)

197 = k / 5

k = 197 x 5

k = 985

Now we can use this value for k to find a when b = 3 and c = 3:

a = 985 x (3 / 32)

a = 985 x (3 / 9)

a = 985 x (1/3)

a = 328.333...

Hence, the value of a, when b = 3 and c = 3, is approximately 328.33.

The owner purchases 5 buckets, 10 brushes, 48 towels, and 1 case of air fresheners for the car wash. The total cost of the purchases is $144.08. Each bucket costs $2.89, each brush costs $7.91, and each towel costs $0.36.

PART B: What is the total cost, in dollars, of the case of air fresheners? Explain/justify your answer.

Answers

5 buckets at $2.89 = 5($2.89) = $14.45
10 brushes at $7.91 = 10($7.91) = $79.10
48 towels at $0.36 = 48($0.36) = $17..28

These three added together makes $110.83. This leaves us $144.08-$110.83=$33.25 for the cost of the case of air fresheners.

What is a function?

If Josiah claims that the ordered pair (6, –10) can be replaced with any ordered pair and the set will still represent a function.

A company sells cereal in two different -sized boxes.The smaller box has the dimensions of 12-inch,2-inch and 7 3/4 i.The height of the smaller box is 80% of the height of the lager box,while the other two dimensions are the same for both boxes.What is the difference in the volumes of the two boxes?

Answers

We will take the volume of each box separately to find the difference between them.
We have then that the volume of the boxes is:
V = (L) * (W) * (h)
Where,
L: long
W: width
h: height
The smaller box:
V1 = (12) * (2) * (7 3/4)
V1 = 186 in ^ 3
the lager box:
V2 = (12) * (2) * ((7 3/4) * (100/80))
V2 = 232.5 in ^ 3
The difference is:
V2-V1 = 232.5 in ^ 3 - 186 in ^ 3 = 46.5 in ^ 3
Answer:
The difference in the volumes of the two boxes is:
46.5 in ^ 3

Answer: The answer is 232.5

Step-by-step explanation:First you to set up the proportion. If 80% equals to 12. You Would do 80 over hundred becuase percent is out of hundred (80/100) then you would do 12 over x or any other variable. FROM there on you would to the butter fly method. Cross multiply . ( 80 times variable, 12 times 100) now to isolate the variable you have to do inverse operation. So now do 1200 divided by 80 . And 80 divided by 80. Now you know.

X=15.

But were no done yet lol. Now do length times width times height to get the volume. 15 times 2 times 31/4 (7 3/4) . now we're done. Your welcome

In a certain card game, for every 44 blue cards, there are 33 yellow cards. There are a total of 84 blue and yellow cards in the game.
How many blue cards are in the game

Answers

Use a proportion.

A ratio of 44 blue to 33 yellow is the same as a ratio of 4 blue to 3 yellow.

Since you are told the total of cards, 84, add 3 + 4 = 7

In the deck, the cards are int he ratio of 4 blue to 3 yellow to 7 total.

4 blue to 7 total = x blue to 84 total

4/7 = x/84

7x = 4 * 84

x = 4 * 12

x = 48

There are 48 blue cards.

x=-5

The vertical asymptote is x=-5

Answer: Option A. x=-5

The vertical asymptote of the function f(x) = (3/x) + 5 is A. x = - 5

What are asymptotes?

A line that, in analytical geometry, is an asymptote of a curve is one where, when one or both of the x or y coordinates go to infinity, the distance between the curve and the line approaches zero. An asymptote of a curve is a line that is tangent to the curve at a point at infinity in projective geometry and similar contexts.

By observing the graph we can conclude that the asymptote or more specifically the vertical asymptote of the function f(x) = (3/x) + 5 is at x equals to - 5.

What is the perimeter of this figure?

Use 3.14 for π.

Answers

423.52 m should be the right one
First The rectangle part with the length is 105m, so you add 105 with 105 that make 210.
For the semicircle part,
we need to find the circumference of the circle
C = 2*pi*r ==> semi Circle circumference = 1/2(2*pi*r) = pi*r
68 is diameter ==> radius should be 34, and the Circumference of 1 semicircle should be 34*pi. We have 2 semicircles, so 2 have 68*pi
In the end Total perimeter = 210 + 68*pi = 423.52

The perimeter of the figure is 423.52 m

What is Area of Rectangle?

The area of Rectangle is length times of width.

From the figure the length of rectangle is 105m and width is 68m.

Perimeter of rectangle=2(length+width)

First the rectangle part with the length is 105m,

2(105)=210m

For the semicircle part, the circumference of the circle is 2πr

The circumference of the semicircle is 1/2(2πr)=πr

Diameter of semicircle=68

Radius is 34

circumference of the semicircle is 34(3.14)=106.76

As there are two semicircles=2(106.76)=213.52

The total perimeter of this figure is 213.52+210=423.52m
