Step-by-step explanation:

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

The number of different committees that can be formed is 34,650.

First, we know that there are 11 teachers and the committee needs to have two teachers, so let's find the number of combinations here.

Remember that if we have a set of N elements and we need to select K of these, the number of different selections is given by:

[tex]C(N, K) = \frac{N!}{(N - K)!*K!}[/tex]

In this case we would have N = 11 and K = 2, so we get:

[tex]C(11, 2) = \frac{11!}{(11 - 2)!*2!} = \frac{11*10}{2} = 11*5 = 55[/tex]

There are 55 combinations.

For the students we do the same thing, here we have 36 students and we need to select two, so:

[tex]C(36, 2) = \frac{36!}{(36 - 2)!*2!} = \frac{36*35}{2} = 630[/tex]

So we have 55 combinations for the teachers and 630 for the students, then the total number of different committees is:

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

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

Using Cramer's rule, the solution to the system of equations is given as follows:

x = -10, y = 9.

A system of equations is when multiple variables are related, and equations are built to find the numeric values of each variable, according to the relations built in the problem.

There are multiple ways to solve a system of equations, and one of them is Cramer's Rule, in which we use the determinants of matrices to find the solutions.

In the context of this problem, the system is:

The matrix for the system is:

[tex]M = \left[\begin{array}{cc}1&2\\-3&-2\end{array}\right][/tex]

Hence it's determinant is:

|M| = 1(-2) - (-3)(2) = -2 + 6 = 4.

The matrix for x is given by:

[tex]M_x = \left[\begin{array}{cc}8&2\\12&-2\end{array}\right][/tex]

Hence it's determinant is:

|Mx| = 8(-2) - 2(12) = -16 - 24 = -40.

The matrix for y is given by:

Answer:   The graph is below

======================================================

Explanation:

If x = 0, then,

g(x) = -x+1

g(0) = -0+1

g(0) = 0+1

g(0) = 1

Therefore, x = 0 leads to y = 1. The point (0,1) is on the g(x) line.

Now try x = 1

g(x) = -x+1

g(1) = -1+1

g(1) = 0

The point (1,0) is also on the g(x) line.

Draw a line through the points (0,1) and (1,0)

Then erase the portion that is to the left of x = -4

This is because g(x) is only graphed when x > -4; i.e. we're only graphing stuff to the right of x = -4.

We'll have an open hole when x = -4 since we aren't including it as part of the graph.

Ms. Lantz would need to finish in 50.28 minutes to be eligible for the Houston Marathon.

The relationship between a score and the mean over a set of scores is simply quantified by a Z-Score, which is a measurable statistic.

A Z-score can explain to a trader why a value is unusual or average for a given set of data.

A Z-score below 1.8 suggests that a company is on the verge of bankruptcy, while a score closer to 3 shows that the company is doing well financially.

Solution:

The z-score is calculated using the formula: 

z = (x - μ)/σ

μ = Sample's average

σ = Sample's standard deviation

The values are as follows:

μ equals 57 minutes.

σ = 8 minutes

Probability equals 20%, or 0.20.

Determine the z-score for 0.20 using the negative z-table.

Z score is -0.84.

To find x, enter the values into the z formula.

z = (x - μ)/σ

-0.84 = (x - 57)/8

Simplifying;

x = -6.72 + 57

x = 50.28 minutes

Thus, Ms. Lantz would need to complete the Rocket Run 5k in 50.28 minutes in order to be eligible for the Houston Marathon.

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.
