Answer:

$2,239.66

Step-by-step explanation:

To find the amount of reimbursement, convert miles to km by multiplying 1564 by 1.609 since 1 mile = 1.609 km.

He drive 1564(1.609)=2,516.476 km.

Multiply this distance by $0.89 per km.

2516.476(0.89)=$2,239.66

1024/2=528(~512)/2=256/2=128/2=64/2=32

the value effects it by now much they have so you can determine who has the most and who has the least

Answer:

a. 13,2 in.

Step-by-step explanation:

66 : 2.5 = 26.4

0.5 x 26.4 = 13.2

By creating a proportion based on the heights shown in the photo and Alice's actual height, we can calculate that Alice's dog's actual height is 13.2 inches, which is option A.

To find out how tall Alice's dog is in reality, we need to use the ratio of their heights in the photograph to determine the dog's actual height. In the photograph, Alice's height is 2.5 inches and her dog's height is 0.5 inches, while her actual height is 66 inches. This creates a ratio that we can use to calculate the dog's actual height.

First, we set up a proportion where the height of Alice in the photo is to her actual height as the height of the dog in the photo is to the dog's actual height:

2.5 inches / 66 inches = 0.5 inches / x inches

Now we solve for x, which represents the dog's actual height:

x = (0.5 inches * 66 inches) / 2.5 inches

After performing the multiplication and division, we get:

x = 13.2 inches

Therefore, the height of Alice's dog in reality is 13.2 inches, which corresponds to option A.

ANSWER

Converges

[tex]S_{ \infty } = 68[/tex]

EXPLANATION

The guy sequence is

17 + 12.75 + 9.5625 + ...

The common ratio is:

[tex] \frac{9.5625}{12.75} = \frac{12.75}{17} = \frac{3}{4} = r[/tex]

Since

[tex] |r| < 1[/tex]

the series converges.

The sum to infinity of this sequence is :

[tex]S_{ \infty } = \frac{a}{1 - r} [/tex]

where a=17 is the first term of the series.

[tex]S_{ \infty } = \frac{17}{1 - \frac{3}{4} } [/tex]

[tex]S_{ \infty } = \frac{17}{ \frac{1}{4} } = 68[/tex]

Answer:

The value of x is 6 and -6. The smallest value of x is -6

Step-by-step explanation:

2/3 x² = 24

solving this equation for finding the value of x.

Multiply both sides by 3/2

x² = 24 * 3/2

x² = 72/2

x² = 36

Now, to find the value of x taking square root on both sides

√x² = √36

x= ±6

So, the value of x is 6 and -6. The smallest value of x is -6

Answer

A) $10

Step-by-step explanation:

Answer: it should be 3 units down

Think if it on a graph in your mind and plot points then use every choice to see which makes sense

For this case we have:

Let k> 0:

To graph [tex]y = f (x) + k,[/tex] the graph k units is moved up.

To graph [tex]y = f (x) -k[/tex], the graph moves k units down.

Let h> 0:

To graph [tex]y = f (x-h)[/tex], the graph moves h units to the right.

To graph [tex]y = f (x + h)[/tex], the graph moves h units to the left.

So, we have:

[tex]y = f (x) = \sqrt {x}\\h = 3\\y = f (x) = \sqrt {x + 3}[/tex]

It means that it was shifted 3 units to the left

Answer:

Option A

Answer:

$12 per dozen muffins

Step-by-step explanation:

3.00/3 = 1

1x = the price of one muffin

1(12) = 12

Step 1: Find what the price is per muffin. To do this you must divide $3.00 by 3 muffins (this will tell you dollar per muffin or $/muffin)

3 ÷ 3 = 1

This means that every muffin is $1

Since we know this, and we know that a dozen means 12 we can multiply 1 by 12 to find how much you would pay for a dozen muffins

12 × 1 = 12

It's $12 per dozen muffins

Answer:

24 and 8

Step-by-step explanation:

The formula for the perimeter of the rect. is P = 2W + 2L.

Here, L = 2W + 8, so the area formula becomes:

P = 2W + 2(2W + 8) = 64

Dividing all terms by 2 reduces this to:

         W + 2W + 8 = 32, or 3W = 24, or W = 8.

Then:  L = 2W + 8 = 2(8) + 8 = 24

Check:  does 2W + 2L = 64 when these values for W and L are substituted?

              Is 2(8) + 2(24) = 64   true?  Yes

The length and width are 24 and 8 respectively.

The length of rectangle will be 8 units.

The width of rectangle will be 24 units.

What is mean by Rectangle?

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Given that;

The length of a rectangle is eight more than twice the width.

The perimeter is 64.

Now,

Let the width of rectangle = x

Then, The length of rectangle = 2x + 8

Here, The perimeter is 64.

So, We get;

2 (length + width) = 64

2 (2x + 8 + x) = 64

2 (3x + 8) = 64

3x + 8 = 64/2

3x + 8 = 32

3x = 32 - 8

3x = 24

x = 8

Thus, The width of rectangle = x

                                            = 8

Then, The length of rectangle = 2x + 8

                                              = 2 × 8 + 8

                                              = 24

Therefore, The length of rectangle will be 8 units.

The width of rectangle will be 24 units.

Answer:

x = 4, y = 2

Step-by-step explanation:

Given the 2 equations

5x + 2y = 24 → (1)

5y = x + 6 → (2)

Rearrange (2) expressing x in terms of y by subtracting 6 from both sides

x = 5y - 6 → (3)

Substitute x = 5y - 6 into (1)

5(5y - 6) + 2y = 24 ← distribute and simplify left side

25y - 30 + 2y = 24

27y - 30 = 24 ( add 30 to both sides )

27y = 54 ( divide both sides by 27 )

y = 2

Substitute y = 2 into (3) for corresponding value of x

x = (5 × 2) - 6 = 10 - 6 = 4

Answer:

A: [tex]y=-3sin(2(x+\pi))+2[/tex]

Final answer:

A fourth degree polynomial with real roots at 0, 3 and a double real root at -1 passes through the point (2, 12). The equation for the function is -2x(x - 3)(x - 3)(x + 1).

Explanation:

A fourth degree polynomial with real roots at 0, 3 and a double real root at -1 can be expressed as:

f(x) = a(x - 0)(x - 3)(x - 3)(x + 1)

To find the value of 'a', we can substitute the point (2, 12) into the equation:

12 = a(2 - 0)(2 - 3)(2 - 3)(2 + 1)

12 = -6a

a = -2

So, the equation for the function is:

f(x) = -2x(x - 3)(x - 3)(x + 1)

Answer:

x = - 5

Step-by-step explanation:

A line with an undefined slope indicates that the line is vertical and parallel to the y- axis.

The equation of a vertical line is

x = c where c is the value of the x- coordinates the line passes through.

The line passes through (- 5, 2) with x- coordinate -5, hence

x = - 5 ← equation of line

The equation of a line that passes through the point (-5, 2) and has an undefined slope is x = -5.

i.e y-axis.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

We have,

The equation of a line passes through the point (-5, 2)

The equation of a line has an undefined slope.

Now,

An undefined slope means,

The line is parallel to the y-axis.

There is only one point on the x-axis.

Slope = Change in y-axis / Change in the x-axis

Slope= Change in y-axis / 0

Slope = undefined

If the slope of a line is undefined there is no y-intercept.

The equation of  the line is:

y = mx + c

y = (1/0)x + 0

0 = x

x = 0

This means the y-axis.

The equation of the line passes through the point (-5, 2) so,

x = -5

Thus,

The equation of a line that passes through the point (-5, 2) and has an undefined slope is x = -5.

Step-by-step explanation:

To find the cost of one ounce of birdseed, first convert the weight to ounces (4 pounds equals 64 ounces) and then divide the total cost by the total number of ounces. The result is approximately $0.11 per ounce.

First, we need to convert the weight from pounds to ounces since there are 16 ounces in 1 pound. So, 4 pounds is equivalent to 4 × 16, which equals 64 ounces.

Now, if 4 pounds (or 64 ounces) of birdseed cost $6.95, we want to find the cost of one ounce. To do this, we divide the total cost by the total number of ounces:

$6.95 / 64{ ounces} = approximately $0.10859375 { per ounce}

This result is the cost per ounce. So, the approximation for the cost of 1 ounce of birdseed is roughly $0.11 (rounded to 2 decimal places).

Margin of Error is simply a range, an amount that is allowed for in case of miscalculation or change of circumstances. The margin of error is 5%.

1. Find the 5% of 3.20 = .16

2. Subtract and add .16 to 3.20 to get rid of that margin of error

    3.20 + .16 = 3.36 and 3.20 - .16 = 3.04
