Since your final answer is in scientific notation, its 7.4 x 10^13

Answer:

10m.

Step-by-step explanation:

Since there is no remainder we simply need to find the least common multiple of each of the lengths of Janice and Jasmin's strings until we find a multiple that matches for each. Like so...

2*1 = 2                    5*1 = 5

2*2 = 4                   5*2 = 10

2*3 = 6

2*4 = 8

2*5 = 10

Finally, we have found the first common multiple which is 10m. That means that the shortest equal length for both Janice's and Jasmin's ribbon is 10m.

Answer:

f(3) = 19

Step-by-step explanation:

Step 1: Define

f(x) = 2x² + 1

x = 3

Step 2: Substitute and Evaluate

f(3) = 2(3)² + 1

f(3) = 2(9) + 1

f(3) = 18 + 1

Answer:

30 1/4

Step-by-step explanation:

At the beginning day of the day the stock market goes down to 60 1/4 points

At the end of the day the stock market increased to 90 1/2 points

Therefore the total change in stock market from beginning of the day to end of the day can be calculated as follows

= 90 1/2 - 60 1/4

= 181/2 - 241/4

= 121/4

= 30 1/4

Hence the total change in stock market is 30 1/4

Step-by-step explanation:

According to the information we can infer that the equation for the road with a maximum incline of 12% can be expressed as y = 0.12x, where 'y' represents the vertical change in meters and 'x' represents the horizontal change in meters.

In the given scenario, the maximum recommended incline for a highway is 12%, which means the road changes 12 meters vertically for every 100 meters of horizontal change.

To represent this relationship mathematically, we can use the equation of a straight line, which is
y = mx,

where
'm' is the slope of the line.

In this case, the slope corresponds to the vertical change (rise) divided by the horizontal change (run), which is 12 meters divided by 100 meters, or 0.12.

Thus, the equation for the road with these characteristics is y = 0.12x, where 'y' represents the vertical change in meters and 'x' represents the horizontal change in meters.

The maximum recommended inclination for a highway is 12%, that is, at its maximum inclination the highway would change 12 meters vertically for every 100 meters of horizontal change.

What equation is generated on the highway that has these characteristics?

Answer:

7

Step-by-step explanation:

The graph that is drawn here shows the altitude as a function of time. When the plane takes off from Chicago, the graph will start from the horizontal axis.

Next, when the plane takes 3 intermediate stops, altitude will touch the horizontal axis 3 times.

Next, when the plane lands in New York the altitude will touch the horizontal axis.

Next, when plane takes off from New York and takes an intermediate stop, altitude will touch horizontal axis.

Lastly the altitude will touch the axis when plane lands back in Chicago.  

So, cumulatively the altitude will touch the horizontal axis seven times.

The graph will touch the horizontal axis (i.e., the ground level) four times during the round trip.

A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.

First, the plane will take off from the Chicago airport, which is at ground level, so the graph will start at the horizontal axis.

Second, the graph will touch the horizontal axis again when the plane lands at the intermediate stop on the way to New York.

Third, the graph will touch the horizontal axis a third time when the plane lands at the intermediate stop on the way back to Chicago.

Fourth, the graph will touch the horizontal axis again when the plane lands back in Chicago at the end of the round trip.

Therefore, the answer is D) 4.

Step-by-step explanation:

Find the cube root of both sides of the equation.

[tex]^3\sqrt{v^3}[/tex] = [tex]^3\sqrt{80}[/tex]

The cube root will cancel out the cubed in the variable.

v = [tex]^3\sqrt{80}[/tex]

Find the cube root of 80. I rounded to the nearest hundredth.

v = 4.31

Answer: [tex]v=2\sqrt[3]{10}[/tex] or 4.3

Answer:

c. The mapping represents y as a function of x, because each x-value is related to exactly one y-value.

Step-by-step explanation:

A mapping can be considered to be a function if any of the following conditions met:

1. Every x-value has exactly only 1 possible y-value mapped to it.

2. Two or more x-values can be mapped to the same y-value provided each x-value is not having more than 1 y-value. That is, provided condition 1 is maintained.

Now looking at the mapping given, every x-value you see there is mapped to exactly just 1 y-value. No x-value is mapped to more than 1 y-value.

However, 3 different x-values, -3, 0, and 8, have the same y-values, 4. This also fulfills the condition for a mapping to be regarded as a function, as a y-value of a function can have more than 1 possible x-value mapped to it.

Therefore the mapping represents y as a function of x.

The mapping represents y as a function of x, because each x-value is related to exactly one y-value.

A mapping can be considered to be a function if any of the following conditions met:

Condition : Mapping denotes the relation from Set A to Set B. Relation from A to B is the subsets A[tex]\times[/tex]B. Mapping the oval on the left-hand side denotes the values of Domain and the oval on the right-hand side denotes the values of Range.

Now looking at the mapping given, every x-value you see there is mapped to exactly just 1 y-value. No x-value is mapped to more than 1 y-value.

However, 3 different x-values, -3, 0, and 8, have the same y-values, 4. This also fulfills the condition for a mapping to be regarded as a function, as a y-value of a function can have more than 1 possible x-value mapped to it.

Therefore the mapping represent y as a function of x.

Step-by-step explanation:

Year 1 = 2000

Year 5 = 4000

Year 10 = 8000

Year 15 = 16000

Year 20 = 32000

5 years = 16000

1 year = 16000/5

1 year = 3200

16000 (15yrs) + 3200 (1yr) = 19200

6/10 × 3200 = 0912

16000 (15yrs) + 3200 (1yr) + 912 (.6yr) = 20112

Step-by-step explanation:

Answer:

9x+ 28 = 5 (x+ 8)

9x+28 = 5x+40        (use distribution property)

4x+28 = 40             (subtract 5x when bringing to the other side)

4x = 40-28               (subtract 28 when bringing to the other side)

4x = 12                    

x = 12/4                     (divide)

x = 3

[tex]\tt Step-by-step~explanation:[/tex]

When we solve for x, we have to move all the numbers that do not contain the variable on one side, and keep x on the other side. In other words, we have to isolate the variable.

[tex]\tt Step~1:[/tex]

Equation: 9x + 28 = 5 (x + 8)

Using PEMDAS*, we will distribute the 5 to x + 8.

[tex]\tt 5(x+8)\\5x+40\\9x+28=5x+40[/tex]

[tex]\tt Step~2:[/tex]

Then, let's subtract 28 from the left side of the equation to cancel the 28, then do the same thing on the right side.

[tex]\tt 9x+28(-28)^{**}=5x+40(-28)^{**}\\9x=5x+12[/tex]

[tex]\tt Step~3:[/tex]

Subtract 5x from both sides to bring it to the left side of the equation.

[tex]\tt 9x(-5x)=5x(-5x)+12\\4x=12[/tex]

[tex]\tt Step~4:[/tex]

Finally, we can divide both sides by 4 to get x by itself.

[tex]\tt \frac{4x}{4} =x\\\frac{12}{4}=3\\ x=3[/tex]
