Calculate the average rate of change for the given graph from x = 3 to x = 5 and select the correct answer below.

Answers

Answer:

Average rate of change between x = 3 to x = 5 is 0.

Step-by-step explanation:

Given quadratic function s passing through two points (3, 0) and (5, 0).

Average rate of change of a function between x = a and x = b is given by,

Average rate of change = [tex]\frac{f(b)-f(a)}{b-a}[/tex]

From the graph attached,

Average rate of change between x = 3 to x = 5 will be,

= [tex]\frac{f(5)-f(3)}{5-3}[/tex]

= [tex]\frac{0-0}{5-3}[/tex]

= 0

Therefore, average rate of change between x = 3 to x = 5 is 0.

Answer: The average rate of change for the given graph from x=3 to x=5 is 0

Answers

Answer: 8y − 56

Step-by-step explanation:

Multiply using the distributive property.

ANSWER: 8y-56

You have to use distributive property when answering this question. 8 goes into y so it turns into 8y and 8 is then multiplied into (-7). So it would be 8(-7) and that equals -56.

eighteen 2.5- gallon buckets are needed to fill a cistern of water

How many 3-gallon buckets of water will fill the cistern.

Answers

Answer:

15 3-gallon buckets of water will fill the cistern

Step-by-step explanation:

Eighteen 2.5- gallon buckets are needed to fill a cistern of water

This means, 2.5 gallon buckets in 18 places

2.5 gallons × 18 = 1 cistern of water

45 gallons = 1 cistern of water

How many 3-gallon buckets of water will fill the cistern.

Number of 3-gallon bucket in a cistern = Total gallons of bucket in one cistern / 3-gallon buckets

= 45 gallons / 3-gallon buckets

= 15

Number of 3-gallon bucket in a cistern = 15

15 3-gallon buckets of water will fill the cistern

Which fraction names the shaded part of the set?

Answers

It would be 4/12 which is equal to 1/3.

The answer is 1/3

The fraction of the shaded part of the set is 1/3.

Given is a figure in which there are total 12 parts with 4 parts shaded.

We need to find the fraction of the shaded part of the set,

To find the fraction of the shaded part of the set, we need to determine the ratio of the number of shaded parts to the total number of parts.

In this case, the total number of parts is 12, and the number of shaded parts is 4.

Therefore, the fraction of the shaded part can be calculated as follows:

Fraction of shaded part = Number of shaded parts / Total number of parts

Fraction of shaded part = 4 / 12

Simplifying the fraction, we get:

Fraction of shaded part = 1 / 3

So, the fraction of the shaded part of the set is 1/3.

express 0.0003 in Scientific notation by counting decimal places

Answers

Answer:

When we write numbers in scientific notation, we must put the first non-zero digit ahead of the decimal.  In this case, the decimal would be behind the 3. Because we moved the decimal places four times to the right, our exponent will be 4. Thus,

3.00 x 10⁻⁴

we can express 0.0003 as 3 × 10⁻⁴ in scientific notation.

To express 0.0003 in scientific notation, we count the number of decimal places from the original number until we have a single non-zero digit before the decimal point. In this case, we have four decimal places before the non-zero digit (3).

Thus, we can express 0.0003 as 3 × 10⁻⁴ in scientific notation. The negative exponent (-4) indicates that we move the decimal point four places to the left to obtain the original value.

In summary, by counting the decimal places, we can express 0.0003 as 3 × 10⁻⁴ in scientific notation.

23$.
In 8 months it will cost 1/3 its original price so you multiple the original price by 1/3.
69.00*1/3
This is the same as dividing by three so just divide 69 by 3 and you get 23.
