Step-by-step explanation:

The complete table of values is:

x  -2  -1  0  1  2

y 1/9  1/3 1  3  9

From the question, we have the following equation:

f(x) = 3ˣ

From the table of values, we have the following x values

x = -2, -1, 0, 1 and 2

Substitute x = -2, -1, 0, 1 and 2 in the equation f(x) = 3ˣ

When x = -2

f(-2) = 3⁻² = 1/9

When x = -1

f(-1) = 3⁻¹ = 1/3

When x = 0

f(-1) = 3⁰ = 1

When x = 1

f(1) = 3¹ = 3

When x = 2

f(2) = 3² = 9

Hence, the complete table of values is:

When the perimeter of the rectangle is 70 in, the length and width are 19 and 16 inches.

It should be noted that the perimeter of a rectangle will be calculated as:

= 2(Length + Width)

In this case, the length of a rectangle is 3in longer than it’s width and the perimeter of the rectangle is 70 in.

Therefore, width = w

length = w + 3

The perimeter will be:

2(w + w + 3) = 70

2(2w + 3) = 70

4w + 6 = 70

Collect like terms

4w = 70 - 6

4w = 64

Divide

w = 64 / 4

w = 16

Width = 16 inches

Length = w + 3 = 16 + 3 = 19 inches.

What do you mean by percentage?

A percentage in mathematics is a number or ratio that is expressed as a fraction of 100. The abbreviations "pct.", "pct.", and occasionally "pc" are also used to indicate it, though the percent sign, "%," is most frequently used. A percentage has no dimensions and no standard measurement.

According to data in the given question,

We have given data:

Cost on the product you make is $112 per unit.

Bid amount $138 per unit,

Cost over the bid= $138-$112 = $26

Now, we need to determine the Percentage increase,

Percentage increase[tex]= \frac{26}{112}*100 \\[/tex]

The slope of the line r is 3 and the y intercept is (0,15) .

We know that coordinates of the point (x,y) after dilation by factor k centered at (a,b) is  (k(x-a) + a , k(y-b) + b)  .

In the question ,

it is given that

the slope of the line p [tex]=[/tex] 3

and the intercept of the line p = (0,2)

So , the equation of the line p is y = 3x + 2 .

So , the coordinates of the point (0,2) after dilation by factor 3 centered at (0,0) is (3(0 - 0) + 0 , 3(5 - 0) + 0)

= (0 , 15)

Point (0,0) does not lie on the line, so the line r after dilation is parallel to the line p,

the slope of line r = 3 , the y intercept is 15 .

Therefore , The slope of the line r is 3 and the y intercept is (0,15) .

Yes, quadrilateral ABCD is a parallelogram.

What are the properties of parallelogram?

A parallelogram is a particular sort of polygon. It is a quadrilateral in which the opposite side pairs are parallel to one another.

Properties:

1. Opposite sides are congruent.

2. Opposite angels are congruent.

3. Consecutive angles are supplementary.

4. If one angle is right, then all angles are right.

5. The diagonals of a parallelogram bisect each other.

6. Each diagonal of a parallelogram separates it into two congruent

It is given that the coordinates of the vertices of quadrilateral ABCD are A (8, -3), B(-2, 1), C (-4,-4), and D(6, -8).

According to distance formula,

If A(a,b) and B(x,y) are two coordinates then

AB = [tex]\sqrt{(x-a)^{2}+(y-b)^{2}}[/tex]

Now, using this distance formula in quadrilateral ABCD

AB = [tex]\sqrt{(-2-8)^{2}+(1+3)^{2}}= \sqrt{(-10)^{2}+(4)^{2}}=\sqrt{100+16}=\sqrt{116}[/tex]

CD = [tex]\sqrt{(6+4)^{2}+(-8+4)^{2}}=\sqrt{10^2+(-4)^2}=\sqrt{100+16}=\sqrt{116}[/tex]

Now, If we have two coordinates A(a,b) and B(x,y) then

Slope of AB = [tex]\frac{y-b}{x-a}[/tex]

Using this formula , finding slope of AB and CD of quadrilateral ABCD we get ,

Slope of AB = [tex]\frac{1+3}{-2-8}=\frac{4}{-10}=\frac{2}{-5}[/tex]

Slope of CD = [tex]\frac{-8+4}{6+4}=\frac{-4}{10}=\frac{-2}{5}[/tex]

As slope of both AB and CD is equal therefore, we can say that AB and CD are parallel.

As AB = CD and AB is parallel to Cd Therefore, ABCD is a parallelogram as opposite sides of parallelogram are equal and parallel.

Hence, quadrilateral ABCD is a parallelogram.

Step-by-step explanation:

The state income tax owed on a $60,000 per year salary.

is tax = $2850.

A percentage is a figure or a ratio that is expressed as a fraction of 100. The percentage sign, "%," is used to denote it. The percentage is denoted by the abbreviations "pct" or "pc." In other words, the percentage is measured in terms of 100 and is defined as the proportion of one quantity that is made up of another.

The % has no boundaries. It implies that they are dimensionless numbers. When we state a number is 60% of something, we are implying that it is 60% of everything. Even fractional versions, like 0.56% or 0.87%, can be used to express it. Students' exam scores in any subject are calculated as a percentage. For instance, Pooja received a 78% on his exam.

Tax slab is as follows:-

0 - 10,000                  =   3%

10,001 - 50,000         =    5%

50,001 - 100,000       =   5.5%

So total salary = $60000

Till $10000 tax deduction will be 3%

So, $10000 * 0.03 = $300

Then from $10,001 - $50,000 tax deduction will be 5%

Hence, the tax deduction will be $40000 * 0.05 = $2000

And from $50,001 - $100,000 tax deduction will be 5.5%

Only $10000 will be available for tax deduction

so, $10000 * 0.055 = 550

Hence total tax deduction will be $2850.

The percentage of blue skittles is 26%.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Total number of skittles = 50

Red skittles = 12

Yellow skittles = 8

Green skittles = 10

Orange skittles = 14%

This means,

= 14/100 x 50

Blue skittles.
