Answer:

The length of a rectangle is 5 centimetres longer than twice its width. If the perimeter of the rectangle is 88 centimetres, what is the width?

width=x

length=2x+5

perimeter=88=2L+2W

so half perimeter=44=L+W

x+2x+5=44

3x=39

x=13 cm width ANSWER

2x+5=31 cm length

The width of the rectangle is Width, W = 13 centimeters.

Given the following data:

Translating the word problem into an algebraic equation, we have;

\(L = 2W + 5\)

To find the width of the rectangle;

Mathematically, the perimeter of a rectangle is given by the formula;

\(P = 2(L + W)\)

Substituting the values into the formula, we have;

\(88 = 2(2W + 5 + W)\\\\88 = 2(3W + 5)\\\\88 = 6W + 10\\\\6W = 88 - 10\\6W = 78\\\\W = \frac{78}{6}\)

Width, W = 13 centimeters.

Therefore, the width of the rectangle is Width, W = 13 centimeters.

Answer:

Dawn earns $9.75 per hour while Amy earns $10 per hour.  

This information is important in comparing who is actually earning more than the other. Amy is earning $0.25 more than Dawn is earning. Thus, working for an extra 2 hours than Dawn made her earn $22.5 more than Dawn earned in a week.

Step-by-step explanation:

You can get the hourly work rate of Dawn and Amy by dividing their total earnings to the number of hours they worked.

You can get the difference in hourly rate by subtracting Dawn's earning from Amy's earning.

You can also get the difference in their weekly earnings by subtracting Dawn's total weekly earning from Amy's total weekly earning.

Mathematics deals with numbers and their variants, equations and related structures, shapes and their locations, and locations where they might be found. A function is an association between inputs and outputs where each input results in a single, unique output. A domain and a codomain, or scope, are assigned to each function. Functions are typically denoted by the letter f. (x). The input is an x. On functions, one-to-one functions, many-to-one functions, within functions, and on functions are the four main categories of functions that are available.

Can you type in the question please and ty

The formula for the future value of an annuity is FV = Pmt * (((1 + r)n - 1) / r) to calculate the balance of the IRA at age 65. To compare this amount to the total deposits made over the time period, Total Deposits = Pmt * n = $45,600.

To calculate the balance of the IRA at age 65, we need to use the formula for the future value of an annuity:

FV = Pmt * ((\((1 + r)^n\) - 1) / r)

Where:

Pmt = $95 (the monthly deposit amount)

r = 4% / 12 = 0.003333 (the monthly interest rate)

n = (65 - 25) * 12 = 480 (the total number of months, assuming retirement at age 65)

Plugging in these values, we get:

FV = 95 * ((\((1 + 0.003333)^480\) - 1) / 0.003333)

FV = $98,052.52

Therefore, the IRA will contain $98,052.52 at age 65.

Part 2

To compare this amount to the total deposits made over the time period, we can calculate the total deposits as:

Total Deposits = Pmt * n

Plugging in the values, we get:

Total Deposits = 95 * 480

Total Deposits = $45,600

Therefore, the IRA will contain significantly more than the total deposits made over the time period, due to the power of compounding interest.

By analyzing the graph and evaluating the objective function at each vertex of the feasible region, we can find the optimal solution, which is the vertex that maximizes the objective function z = 3x + y.

To find the optimal solution of the given problem using the graphical method, we need to plot the feasible region determined by the given constraints and then identify the point within that region that maximizes the objective function.

Let's start by graphing the constraints:

1. Plot the line 2x - y = 5. To do this, find two points on the line by setting x = 0 and solving for y, and setting y = 0 and solving for x. Connect the two points to draw the line.

2. Plot the line -x + 3y = 6 using a similar process.

3. The x-axis and y-axis represent the constraints x ≥ 0 and y ≥ 0, respectively.

Next, identify the feasible region, which is the region where all the constraints are satisfied. This region will be the intersection of the shaded regions determined by each constraint.

Finally, we need to identify the point within the feasible region that maximizes the objective function z = 3x + y. The optimal solution will be the vertex of the feasible region that gives the highest value for the objective function. This can be determined by evaluating the objective function at each vertex and comparing the values.

Note: Without a specific graph or additional information, it is not possible to provide the precise coordinates of the optimal solution in this case.

The initial value problem's solution becomes closer to 0, the problem's limit, as time gets closer to infinity.

1. Determine both sides of the equation's Laplace transform: d2y + 4dy + 13y = u5(t) Y(s) = s2Y(s) + 4sY(s) + 13Y(s) = U5 (s)

2. Rewrite the equation to Y(s) = U5(s) / (s2 + 4s + 13) to find the value of Y(s).

3. Consider the reverse Finding y(t) using the Laplace transform on both sides

y(t) = (1/12)e(-t) + (1/24)sin(3t) + (1/8)cos (3t)

4. As t approaches infinity, determine the limit:

Laplace transformations are used to resolve the initial value issue d2y + 4dy + 13y = u5(t), where y(0) = 0 and y′(0) = 1. Y(s) = s2Y(s) + 4sY(s) + 13Y(s) = U5 is the result of first doing the Laplace transform of both sides of the equation (s). To find Y(s), we rewrite the equation as Y(s) = U5(s) / (s2 + 4s + 13). Then, to get y(t), we use the inverse Laplace transform of both sides: y(t) = (1/24)e(-2t) + (1/12)e(-t) + (1/24)sin(3t) + (1/8)cos (3t). Finally, when t approaches infinity, we compute the limit: limt[infinity]y(t) = 0. As a result, as time gets closer to infinity, the initial value problem's solution gets closer to 0.

Answer: approximately 10.8 centimeters

Step-by-step explanation:

We have a square, where each side measures approx. 4.25 in

Now we know that 1in ≈ 2.54 cm

Then, in 4.25 in, we have 4.25 times 1 inch, so we have 4.25 times the length of 2.54 cm

So the approximate measure of the sides in centimeters is:

4.25*(2.54)cm = 10.8 cm

So we have that each side measures approximately 10.8 centimeters

Answer:

B

Step-by-step explanation:

We have the equation \(-x-2y=-4\) and we want to find which ordered pair is in the solution \(-x-2y\leq -4\)

First, let's convert the inequality to slope-intercept form. So, we have:

\(-x-2y\leq-4\)

Add x to both sides:

\(-2y\leq x-4\)

Divide both sides by -2. Since we're dividing by a negative, we will flip the sign:

\(y\geq- \frac{1}{2}x+2\)

Therefore, our original inequality will be the same as above.

Notice that our y is greater than our equation.

Therefore, the shaded area will lie above our line.

So, any point that falls within the region above our line (in the graph) and on the line is a solution to our inequality.

(-4, 1) is below our line, so it's not a solution.

(-1, 4) is above our line. So, (-1, 4) is our answer.

(-4, -1) is again below our line. So, it's not a solution.

Finally, (4, -1) is also below our line, so it's not a solution.

Therefore, our final solution is B: (-1, 4).

Let's check this. Substitute -1 for x and 4 for y. This yields:

\(-(-1)-2(4)\stackrel{?}{\leq}4\)

Multiply:

\(1-8\stackrel{?}{\leq}{4}\)

Subtract:

\(-7\stackrel{\checkmark}{\leq}4\)

So, (-1, 4) is indeed our solution.

And we're done!

Answer:

Y intercept = (0,4)

X intercept = (6,0)

Step-by-step explanation:

2x+3y=12

To do so, you need to get y on it's own (or on one side)

-3y+12=2x

y-4=-2/3x

y= -2/3x +4

-2/3x= slope while 4= y intercept

You can also graph it on desmos and find the y intercept and x intercept

We want to find the x and y-intercepts of a given equation.

The solution is:

First, we start by defining what x-intercept and y-intercept are.

The x-intercept is the x-value at which the graph of the equation intercepts the x-axis, and is equivalent for the y-intercept.

So, for a given function y = f(x).

We define the y-intercept as the value of y when we define x = 0.

And we define the x-intercept as the value (or values) of x when y = 0.

Here we have:

2x + 3y = 12

So to get the x-intercept, we just need to define y = 0 and solve for x.

2x + 3*0 = 12

2x = 12

x = 12/2 = 6

To get the y-intercept, we just need to define x = 0 and solve for y.

2*0 + 3*y = 12

3*y = 12

y = 12/3 = 4
