Answer:

Step-by-step explanation:

Let's look at car A first.

As already solved, just after it is purchased its value decreases 20%.

Purchased at $30000, its value inmediatly decreases to $24000 ($30000 -

0.2*$30000 = $24000).

We know the yearly depreciation for car A os $2000.

Then, at the end of the first year, its value will decrease from $24000 to $24000 - $2000 = $22000.

Every year its value decreases $2000. Followint the same logic, at the end of the second year its value will decrease from $22000 to $22000 - $2000 = $20000 and so on. Now, we can build the table:

End of first year: $24000 - $2000 = $22000

End of second year: $22000 - $2000 = $20000

End of third year: $20000 - $2000 = $18000

End of fourth year: $18000 - $2000 = $16000

End of fifth year: $16000 - $2000 = $14000

Expected value:

For the given scenario:

As we can see in the card, on Monday the worker clocked in at 08:15 and clocked out at 12:15. This means they worked 4 hours.

They then clocked in at 13:00 and clocked out at 17:30. This means they worked for 4 and a half hours.

Since they earn a wage of $14.50/h, they earned:

So that day they earned $123.25

If An industrial scale is guaranteed by the manufacturer to have a percent error of no more than 1%. Its  possible reading on the scale if you put 500 kilograms of iron ore on it is :495, 505.

Percent error = 1%

Kilogram of iron ore = 500 kilograms

First step is to find the 1% of 500 kilograms

= .01 × 500 kilograms

= 5

Second step is to find the possible reading

Possible reading :

500 - 5

=495

500 + 5

= 505

Therefore we can conclude that  based on the above analysis the possible reading can be between 495 and 505.

The most appropriate choice for perimeter of rectangle will be given by-

Mr Smith must buy 61 m of fencing.

What is perimeter of rectangle?

It is equal to the total distance of the boundary of the rectangle.

If length of rectangle is l m and breadth of rectangle is b m, perimeter of rectangle is 2 x (l + b) [tex]m^2[/tex]

Here,

Length of yard = 61 ft

Breadth of yard = 39 ft

Perimeter of yard = 2 x (61 + 39)

                             = 2 x 100

                             = 200 ft

1 ft = 0.305 m

200 ft = 0.305 x 200 m

          = 61 m

Mr Smith must buy 61 m of fencing.

The dimensions of the rectangular garden are 20 feet and 29 feet respectively.

It is vital to note that the formula for the area of a rectangle is expressed as;

Area = lw

Where;

From the information given, we have that;

Area =  580ft²

Length = 9 + width

L = 9 + w

Substitute the values into the formula, we have;

580 = (9 +w)(w)

expand the bracket

580 = 9w + w²

Make into quadratic equation

w² + 9w - 580 = 0

Factorize the equation

w² + 29w - 20w - 580 = 0

Factor the common terms

w( w + 29) - 20(w + 29) = 0

Then,

w + 29 = 0

w = -29

and w - 20 = 20 feet

We have the expression of length as l = 9 + w

Length, l = 9 + 20

Length, l = 29 feet

Thus, the values are 20 feet and 29 feet

To convert the number given in base 7 to a bse 10 number we follow the procedure shown, that is, we need to multiply each number by the appropiate power of seven (given by their position) and then add them, then we have that:

Therefore:

The simplified form for (3x² + 2y² - 5x + y) + (2x² - 2xy - 2y² -5x + 3y) is (5x² + 0y² - 10x + 4y - 2xy).

At least one squared term must be present because a quadratic is a second-degree polynomial equation. It is also known as quadratic equations. The answers to the issue are the values of the x that satisfy the quadratic equation. These solutions are called the roots or zeros of the quadratic equations. The solutions to the given equation are any polynomial's roots. A polynomial equation with a maximum degree of two is known as a quadratic equation, or simply quadratics.

The equation can be made simpler by adding up all of the coefficients for the specified correspondent term through constructive addition or subtraction of terms, as suggested in the question.

Given, the equation is (3x² + 2y² - 5x + y) + (2x² - 2xy - 2y² -5x + 3y)
Removing brackets and the adding we get,
3x² + 2x² + 2y² - 2y² + (- 5x) + (- 5x) + y + 3y + (- 2xy) = (5x² + 0y² - 10x + 4y - 2xy)

Step-by-step explanation:

Using transformations, the functions that could represent the one graphed are given as follows:

A transformation is when a function undergoes a change in it's definition. Depending on the type of the transformation, the function can keep the same orientation, same side lengths, and so on.

In the context of this problem, the function kept the same orientation, it just changed it's position, hence the type of transformation that the function underwent was a translation.

The possible translations are given as follows:

The domain of the graphed function is given by:

x ≥ 0.

Which is the same domain as the parent square root function, given as follows:

y = sqrt(x).

From the graph, the function was translated down a units, changing it's range, hence the function has the following format:

y = sqrt(x) - a.

Hence the first two options can be correct, either with a = 1 or with a = 3. The last two options change the range but not the domain, hence they are incorrect.

The width of the rectangle DOGS is 119cm

To solve this, since is a ratio problem, we know that the two ratios must add to the total. This is, for a ratio of 5:7, 5 + 7 = 12 is the total "divisions" for the ratio.

This means that if 12 of 12 parts add to the perimeter (408cm):

12/12 represents the perimeter 408cm.

The, we can divide the perimeter by 12 and get:

Since the width is 7/12 of the perimeter:

But, we are taking the perimeter of a rectangle, which is twice the width plus twice the length, thus we need to divide this number by 2:

And we get the final answer of 119cm

Answer:

The rate at which the surface area is changing with respect to time when r = 40 cm is 22400π cm²/min

Step-by-step explanation:

[tex]\text {Volume of a sphere of radius r is given by }\\\\ \text {$V = \dfrac{3}{4}\pi r^3$}[/tex]

The surface area of a sphere of radius r is given by:

[tex]\\S = 4\pi r^2\\[/tex]

The rate of change of surface area is given by
[tex]\dfrac{dS}{dt} = \dfrac{d}{dt}\left(4\pi r^2\right)}\\\\\dfrac{dS}{dt} = 4 \pi \dfrac{d}{dt}\left( r^2\right)}\\\\\\\dfrac{d}{dt}(r^2) = 2r\dfrac{dr}{dt}\\\\\\[/tex]

[tex]\dfrac{dS}{dt} = 8\pi r \dfrac{dr}{dt}[/tex]

We are given that [tex]\text{$\dfrac{dr}{dt}$}[/tex] = 70 cm/min and asked to find rate of change of S when r = 40 cm

Substituting these values into the equation for [tex]\dfrac{dS}{dt}[/tex]
[tex]\dfrac{dS}{dt} = 8 \pi \cdot 40 \cdot 70\\\\\\\\\dfrac{dS}{dt} = 22400 \pi \;cm^2/min[/tex]

The distance expression of the number of units between points A and B is √[(-2 - 3)^2 + (5 - 5)^2]

From the question, we have the following parameters:

This means that

A = (-2, 5)

B = (3, 5)

The distance between the points is calculated as

Distance = √[(x2 - x1)^2 + (y2 - y1)^2]

Where

A = (x1, y1) = (-2, 5)

B = (x2, y2) = (3, 5)

Substitute the known values in the above equation

So, we have

Distance = √[(-2 - 3)^2 + (5 - 5)^2]

The question does not imply that the we simplify the above expression
