What is a linear function?

In Mathematics and Geometry, a linear function refers to a type of function whose equation is graphically represented by a straight line on the xy-plane or cartesian coordinate.

This ultimately implies that, a linear function has the same (constant) slope and it is typically used for uniquely mapping an input variable to an output variable, which both increases simultaneously.

In this context, we can logically deduce that function 2 is a quadratic function and as such, it is the only nonlinear function.

What is 0.65 expressed as a fraction in simplest form?
What is 2.¯5 expressed as a fraction in simplest form?
What is 1.0¯24 expressed as a fraction in simplest form?
Answer:

Part A)



Part B)



Part C)

Answers

Answer:

Step 1: Write down the decimal as a fraction with the decimal number as the numerator and 1 as the denominator.

Step 2: Multiply both the numerator and denominator by 10^n, where n is the number of digits after the decimal point.

Step 3: Simplify the resulting fraction.

Using these steps, we can convert the given decimal numbers to fractions:

0.65

Step 1: 0.65 = 65/100

Step 2: Multiply numerator and denominator by 10 to get rid of the decimal point: 65/100 = 650/1000

Step 3: Simplify by dividing numerator and denominator by their greatest common factor of 50: 650/1000 = 13/20

Therefore, 0.65 expressed as a fraction in simplest form is 13/20.

2.¯5

To handle repeating decimal numbers, we can use the following method:

Step 1: Let x be the repeating decimal number.

Step 2: Multiply both sides of x by 10^n, where n is the number of digits in the repeating part of the decimal number.

Step 3: Subtract the original number from the number obtained in step 2 to eliminate the repeating part.

Step 4: Solve for x by dividing both sides of the equation obtained in step 3 by an appropriate factor.

Step 1: Let x = 2.¯5

Step 2: Multiply both sides by 10: 10x = 25.¯5

Step 3: Subtract the original equation from step 1: 10x - x = 25.¯5 - 2.¯5

Simplifying: 9x = 23

Step 4: Solve for x by dividing both sides by 9: x = 23/9

Therefore, 2.¯5 expressed as a fraction in simplest form is 23/9.

1.0¯24

Step 1: Let x = 1.0¯24

Step 2: Multiply both sides by 10^2 to eliminate the repeating part: 100x = 124.¯24

Step 3: Subtract the original equation from step 1: 100x - x = 124.¯24 - 1.0¯24

Simplifying: 99x = 123

Step 4: Solve for x by dividing both sides by 99: x = 123/99

We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor of 3: 123/99 = 41/33.

Therefore, 1.0¯24 expressed as a fraction in simplest form is 41/33.

Step-by-step explanation:

0.65 expressed as a fraction in simplest form is 13/20.

2.5 expressed as a fraction in simplest form is 5/2.

1.024 expressed as a fraction in simplest form is 256/250.

What is the simplified form of the expressions in fraction?

0.65 expressed as a fraction in simplest form:

Write the decimal as a fraction by placing it over 1. In this case, 0.65 becomes 0.65/1.

Remove the decimal by multiplying both the numerator and the denominator by a power of 10 that will eliminate the decimal.

In this case, multiplying by 100 will do the trick, so we get (0.65 × 100)/(1 × 100) = 65/100.

Lastly, simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor (GCD).

The GCD of 65 and 100 is 5, so dividing both by 5 yields 13/20.

2.5 expressed as a fraction in simplest form:

Write the decimal as a fraction by placing it over 1. In this case, 2.5 becomes 2.5/1.

Remove the decimal by multiplying both the numerator and the denominator by a power of 10 that will eliminate the decimal.

In this case, multiplying by 10 will do the trick, so we get (2.5 × 10)/(1 × 10) = 25/10.

Lastly, simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor (GCD).

The GCD of 25 and 10 is 5, so dividing both by 5 yields 5/2.

1.024 expressed as a fraction in simplest form:

Write the decimal as a fraction by placing it over 1. In this case, 1.024 becomes 1.024/1.

Remove the decimal by multiplying both the numerator and the denominator by a power of 10 that will eliminate the decimal.

In this case, multiplying by 1000 will do the trick, so we get (1.024 × 1000)/(1 × 1000) = 1024/1000.

Simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor (GCD).

The GCD of 1024 and 1000 is 8, so dividing both by 8 yields 128/125.

Jaden made a rectangular sign that is 1.4 meters long and 1.2 meters wide to post on the wall of his store. How many square meters of wall does the sign cover? The answer is 1.68, but to solve the problem, you need to find 1.4 x 1.2(which it is 1.68). Estimate the area of wall that the sign will cover. Explain your thinking please.

Answers

To estimate the area of the wall that the sign will cover, we can use some rounding techniques to simplify the calculation.

First, we can round the dimensions of the sign to the nearest whole number to make the multiplication easier. Rounding 1.4 to 1 and 1.2 to 1, we can estimate that the sign covers approximately 1 square meter of wall.

This estimation assumes that the sign is placed directly on the wall with no gaps or overlaps. In reality, the actual area of wall covered by the sign may be slightly larger or smaller depending on the installation method and any spacing between the sign and the wall.

It's important to note that while estimation can be useful for getting a rough idea of the answer, it's not always accurate and should not be relied upon for precise calculations. In this case, using the actual dimensions of the sign to find the area of the wall covered (1.4 x 1.2 = 1.68 square meters) gives a more accurate result.

The diameter of a child's bicycle wheel is 18 inches. Approximately how many revolutions of the wheel will it take to travel 1,700 meters? Use 3.14 for π and round to the nearest whole number. (1 meter ≈ 39.3701 inches)
A. 3,925 revolutions
B. 2,368 revolutions
C. 1,184 revolutions
D. 94 revolutions

Answers

First, we need to convert the diameter of the wheel from inches to meters.

18 inches = 0.4572 meters (dividing by 39.3701)

The circumference of the wheel can be calculated using the formula C = πd, where d is the diameter of the wheel.

C = π(0.4572) = 1.4368 meters (using 3.14 for π)

Now we can find the number of revolutions needed to travel 1,700 meters.

Distance covered by one revolution = circumference of the wheel = 1.4368 meters

Number of revolutions = distance to be covered / distance covered by one revolution

Number of revolutions = 1,700 / 1.4368 = 1,183.52

Rounding to the nearest whole number, we get the answer as C. 1,184 revolutions.

Leah is filling a cube-shaped box with packing material and gift items. Each edge length of the box is 20 inches. What is the greatest possible volume of all the presents and packing material inside the cube?

(Answer needed by 11:30pm-12:30pm)

Answers

Since the box is cube-shaped with each edge length being 20 inches, the volume of the box is calculated as 20 x 20 x 20 = 8,000 cubic inches.

To find the greatest possible volume of all the presents and packing material inside the cube, we need to fill the entire volume of the box.

Assuming that the packing material takes up some space, let's say half of the total volume or 4,000 cubic inches, the remaining 4,000 cubic inches would be the maximum possible volume for the gift items.

Therefore, the greatest possible volume of all the presents and packing material inside the cube is 4,000 cubic inches.

The table below shows the change in price of a particular share on the stock market.
Daily share price changes
Day Daily change (In dollars)
1 +2.75
2 -4.375
3 +0.875
4 -2.5

Part A: By how did the price of the share change from the start of day 1 to the end of day 4?

Part B: At the end of day 4 the price of the share is $102.85. What was the price of the share at the start of day 1?

Answers

Answer:

Part-a: The price of the share decreased by $3.25 from the start of day 1 to the end of day 4.

Part-b: The price of the share at the start of day 1 was $106.10.

Step-by-step explanation:

Part A: To calculate the change in price from the start of day 1 to the end of day 4, we need to add up all the daily changes. The daily changes given are:

Day 1: +2.75

Day 2: -4.375

Day 3: +0.875

Day 4: -2.5

Adding these values together:

Change = 2.75 - 4.375 + 0.875 - 2.5 = -3.25

The price of the share decreased by $3.25 from the start of day 1 to the end of day 4.

Part B: To find the price of the share at the start of day 1, we need to subtract the total change from the given price at the end of day 4.

Price at the end of day 4 = $102.85

Total change = -3.25

Price at the start of day 1 = Price at the end of day 4 - Total change

= $102.85 - (-3.25)

= $102.85 + 3.25

= $106.10

Therefore, the price of the share at the start of day 1 was $106.10.

Choice D: The theoretical probability, P(green), is 50%, and the experimental probability is 7.0%.

PLEASE HELP ASAP!!!!!!!

Answers

To compare the theoretical probability and experimental probability of pulling a green marble from the bag, we first need to calculate the theoretical probability of pulling a green marble.

The bag contains a total of 40 marbles, and 10 of them are green. Therefore, the theoretical probability of pulling a green marble is:

P(green) = 10/40 = 1/4 = 0.25 = 25%

To calculate the experimental probability of pulling a green marble, we can use the frequency table given in the problem. Out of the 40 trials, a green marble was pulled 7 times. Therefore, the experimental probability of pulling a green marble is:

Experimental probability of pulling a green marble = Frequency of green marbles / Total number of trials
= 7/40
= 0.175
= 17.5%

Therefore, the correct answer is Choice C: The theoretical probability, P(green), is 25%, and the experimental probability is 17.5%.
