Which graph represents a function that has the domain (–∞, –4) ⋃ (–4, 3) ⋃ (3, ∞), has a y-intercept at (0, 3), and is increasing on the interval (0, 4)?

Answer:

414/3

Step-by-step explanation:

If she has 414 inches of ribbon and uses 3 inches for each bow then that means that you would have to divide 414 by 3 in order to find the amount of bows that Jesse could make

The simplified expression represents how much Meera spends giving directions is D. 6a + 2r.

A simplified expression is a mathematical expression that has completed the mathematical operations of adding, subtracting, multiplying, and dividing with the known values.

Given a simplified expression, the work left would be to fill in the independent variables.

The total time spent answering phone calls = a

The total time spent responding to emails = r

The total time spent giving directions = 4a + 2(a + r) = 6a + 2r

Thus, we can conclude that Meera spends six times the amount she spends answering the phone and two times the time she spends responding to emails to give directions.

Answer: z=8

Step-by-step explanation:

5.3=z-2.7

5.3+2.7=z-2.7+2.7    ==> remove the 2.7 in 'z-2.7' to single out the variable z.

z=5.3+2.7

z=8

z = 8 ✅

Step 1:

Add 2.7 to both sides

5.3 = z - 2.7

5.3 + 2.7 = z - 2.7 + 2.7

      ⬆️                   ⬆️

Step 2:

Simplify

5.3 + 2.7 = z - 2.7 + 2.7

The perimeter of the regular polygon is 232

The side lengths of the regular polygon are given as

4/3x - 1/3 and x + 7

The sides of regular polygon are equal

So, we have:

4/3x - 1/3 = x + 7

Multiply both sides by 3

4x - 1 = 3x + 21

Collect like terms

4x - 3x = 1 + 21

Evaluate the like terms

x = 22

Substitute x = 22 in x + 7

Side = 22 + 7

Side = 29

The perimeter of the regular polygon is calculated as:

Perimeter = Number of sides x Side length

So, we have

Perimeter = 8 * 29

Evaluate

Perimeter = 232

Hence, the perimeter of the regular polygon is 232

Answer:

  1000

Step-by-step explanation:

You want the next number after 222 in base 3.

In any useful number base, the counting at any given integer position is ...

  0, 1, 2, 3, ..., (base -1), 0 and add 1 to the next number position

For base 3, this is ...

  0, 1, 2, 10

When the digit in the next higher position is also (base -1), then it gets incremented to 0 and the carry is propagated to the left.

In base 10, the equivalent is ...

  999 +1 = 99(9+1) = 99(10) = 9(9+1)0 = 9(10)0 = (9+1)00 = 1000

In base 3, your incremented value is ...

  222 +1 = 22(2+1) = 22(10) = 2(2+1)0 = 2(10)0 = (2+1)00 = 1000

The next whole base 3 number after 222 is 1000.

The actual roller coaster is 204 ft tall.

Given that, the length of the model roller coaster is 4 ft and the scale factor is 1/51.

The scale factor is defined as the number or the conversion factor which is used to change the size of a figure without changing its shape. It is used to increase or decrease the size of an object.

Let the length of the actual roller coaster be x.

We know that Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape.

Now, 1/51 = 4 / x

⇒x=204 ft

Therefore, the actual roller coaster is 204 ft tall.

The coordinates of C' after a reflection across the line y = -2 are (3, -2).

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, translation and dilation.

Given that the verticles of ABC are A(-4,5,)B(-2,4), and C(-3,2). If ABC is reflected across the line y = - 2 to produce the image ABC, then we need to find the coordinates of the vertex C.

Let (x, y) represent the coordinate of the point C

x-coordinate value:

The line y = -2 is parallel to the x-axis, therefore the x-value will remain the same following a reflection across the x-axis.

Taking the point C' as the image of the corresponding point C(-3,2), we need that the x-coordinate of the point C' is also 3

x = 3

y-coordinate value:

The difference between the coordinate of the pre-image and the reflecting line is same as difference between the reflecting line and the coordinates of the image.

Therefore, the coordinates of the point C' is (x, y) = (3, -2)

The correct scientific notation of [0.789×(10⁵)] is 78900.

As per the question statement, we are provided with a multiplication of a decimal number and an exponential number.

We are required to determine its correct scientific notation.

A decimal number, say 0.059, can be expressed as a multiplication of a decimal number and an exponential number, such as [5.9×(10)⁻²].
But in our case, after performing the multiplication of the given values, we get, [tex][0.789*10^{5}]=(\frac{789}{1000}*100000)=(789*100)=78900[/tex]

And 78900 is not a decimal value. Hence, the correct scientific notation of [0.789×(10⁵)] is 78900.

[Note: Here, we need to know the procedure to convert a decimal into a fraction, using which we converted 0.789 into [tex]\frac{789}{1000}[/tex]. First, we will need to eliminate the decimal point and consider the digits in the same order as a complete number which will be our numerator. Secondly, we will use (10ⁿ) as the denominator, where "n" is the number of digits to the right side of the decimal point in the original decimal number. Thus, 0.789 can be written as [tex]\frac{789}{1000}[/tex], as there are three digits to the right of the decimal point in 0.789]

We get the length of the arc that subtends a central angle of 1 radians as 6 miles with radius as 6 miles also.

We are being asked to solve for the length of the arc of a circle.

For this, we are given that:

A radius of around 6 miles.

And a central angle that is subtended by the arc which is equal to 1 radians.

In order to solve for this, we need to use the length of the arc formula.

The formula is:

s = r θ

Where r =  is the radius

and

θ = is the subtended central angle given in radians

Now, by substituting the values in the formula, we get that:

s = 6 mi (1 rad) = 6 miles

Therefore, we get the length of the arc that subtends a central angle of 1 radians as 6 miles with radius as 6 miles also.

After differentiating the function f(x)=3 - 2 x ², we get the result as d y / d x = - 4 x

Differentiation is a process applied to a function which finds the function's rate of change compared to the rate of change of the independent variable.

We are given the function as:

f(x)=3 - 2 x ²

We need to find d y / d x

For this we need to differentiate the function with respect to x.

Differentiating the function with respect to x, we get that:

d y / d x = ( 0 ) - 2 ( 2 x ) ( 1 )

d y / d x = 0 - 4 x

d y / d x = - 4 x

Answer:

Chen family used the sprinklers for 25 hours

Aoki family used the sprinklers for 40 hours

Step-by-step explanation:

Let C be the number of hours the Chen family used the sprinklers and let A be the number of hours the Aoki family used the sprinklers

Total hours used

=> C + A = 65 (1)

Total water usage for Chen family = 40C  (40 L per hour x no. hour)
Total water usage for Aoki family = 25C    (25 L per hour x no. hours)

Total used by both families = 2000 L

So
40C + 25A = 2000           (2)

Therefore we have two equations in 2 variables which can be solved simultaneously

Multiply (1) by 25:
==> 25C + 25A = 25 x 65
==> 25C + 25A = 1,625   (3)

Subtract (3) from (2) to eliminate the A term:
(2) - (3) ==>
40C + 25A - (25C + 25A ) = 2000 - 1625

40C + 25A - 25C - 25A = 375
40C - 25C = 375
15C = 375
C = 375/15

C = 25
So the Chen family used the sprinklers for 25 hours

Since C + A = 65
A = 65 - C
==> A = 65 - 25
A = 40
The Aoki family used the sprinklers for 40 hours

1. No, the set of data does not represent a function.

A function relates an input to an output. It is like a machine that has an input and an output. And the output is related somehow to the input.

We are given with (1,4), (2, 4), (3, 5), (2, 2)

This is because every output of this data does not have unique input.

4 and 2 have the same input i.e. 2.

2. Yes, the set of the data represents a function.

We are given with (10, 5), (12, 5), (7, 12), (12, 2)

It is a function as every input has a single output.
