Answer:

a) Rectangle of maximum area ( given perimeter p ) is

A= x²     That means the rectangle of maximum area,  is a square

Step-by-step explanation:

The equation:   A (x,y) = x*y   is the area of a rectangle  ( to maximize)

Subject to:   p  = 2*x + 2*y    or  g(x,y) =  2*x + 2*y -p

Now

A(x,y) = x*y         δA/δx  = y          δA/δy  = x

And

g(x,y) =  2*x + 2*y -p

δg(x,y)/δx = 2       and    δg(x,y)/δy  = 2

Matching respective partial derivatives we get a system of equation

δA/δx  = y  = λ *  = δg(x,y)/δx = 2  

y = 2*λ

δA/δy  = x  = 2*λ

The system of equations is:

y = 2*λ

x  = 2*λ

And 2*x + 2*y -p = 0

p = 2*x +2*y

So   x = y      p is equal either  4*x  or  4*y

Solving for λ

The Interpretatiom of the equation is that;

w represents number of weeks she will have saved for the remaining items

Answer:

there will be 30 girls at the party

Answer:

There are 30 girls at the party.

Step-by-step explanation:

20 / 2 = 10

10*3 = 30

You divide the 20 boys at the party from the "every 2 boys", and you should get 10.

You then multiply the 10 by 3, for the 3 girls at the party and you should get 30 as an answer, so therefore you should get 30 as your answer.

A function that represents a reflection of \(f(x) = \frac{3}{8} (4)^x\) across the y-axis include the following: D. \(g(x) = \frac{3}{8} (4)^{-x}\).

In Mathematics and Geometry, a reflection over or across the y-axis or line x = 0 is represented and modeled by this transformation rule (x, y) → (-x, y).

This ultimately implies that, a reflection over or across the y-axis or line x = 0 would maintain the same y-coordinate while the sign of the x-coordinate changes from positive to negative or negative to positive.

By applying a reflection over the y-axis to the parent exponential function, we would have the following transformed exponential function:

(x, y)                                              →                 (-x, y).

\(f(x) = \frac{3}{8} (4)^x\)                               →              \(g(x) = \frac{3}{8} (4)^{-x}\)

A = meters
Kilometers are the distance of one thing from another

Centimeters would be too small to measure a two story house

Millimeters is the same explanation as centimeters

Answer:

B

Step-by-step explanation:

The multiplication of the given two matrices A and B gives,

AB = \(\left[\begin{array}{ccc}-9&0\\9&9\end{array}\right]\)

Given two matrices,

A = \(\left[\begin{array}{ccc}1&3&-1\\3&0&3\end{array}\right]\) and B = \(\left[\begin{array}{ccc}3&0\\-4&1\\0&3\end{array}\right]\)

We have to find the product of these matrices.

We have to multiply each row of A with each column of B.3

(AB)₁₁ = (1 × 3) + (3 × -4) + (-1 × 0) = -9

(AB)₁₂ = (1 × 0) + (3 × 1) + (-1 × 3) = 0

(AB)₂₁ = (3 × 3) + (0 × -4) + (3 × 0) = 9

(AB)₂₂ = (3 × 0) + (0 × 1) + (3 × 3) = 9

Hence the product is,

AB = \(\left[\begin{array}{ccc}-9&0\\9&9\end{array}\right]\)

Hence the product is AB = \(\left[\begin{array}{ccc}-9&0\\9&9\end{array}\right]\).

Answer:

1) A

B) 5.818 stops

Step-by-step explanation:

Number One is less than or equal to 21 because the person only has 21 dollars, so she can't spend more than 21.

B can be solved through the equation by first subtracting $5, and then dividing 2.75 by 16.

We have that triangle A has

h = 2.5 cm

b = 1.6 cm

The ratio between its height and base is:

hA / bA = 2.5 cm / 1.6 cm

To be proportional to triangle A, triangle B must have the same ration between height and base:

hB / bB = hA / bA = 2.5 cm /1.6 cm

If we see the options, when hB = 1.25 and bB = 0.8, this is the same ratio as

hA / bA, since hB = (hA / 2), and bB = ( bB = bA / 2) or

hB = (2.5/2) = 1.25

bB = (1.6/2) = 0.8

Therefore, we have:

hA / bA = hB / bB = 2.5 cm /1.6 cm = 1.25 cm / 0.8 cm = 1.5625

Thus, the height and the base of triangle B is h = 1.25 cm and base = 0.8 cm.

(The correct option is D).

The other two options are:

h = 2.75 cm / 1.76 cm = 1.5625 (option A)

h = 2 cm / 1.28 cm = 1.5625

All of these triangles have the same ratio between height and base.

A scatter plot is a graphical representation of a set of data that allows the observer to observe the relationship between two variables. It is used to graphically display how one variable is affected by the other. It is a chart of data points plotted on a two-dimensional graph with one variable represented on the X-axis and the other variable on the Y-axis.

Scatter Plot of the Data: From the data provided by the Language Arts department, we can create the scatter plot as shown below:
Equation of the line of best fit: The line of best fit is a straight line that is used to model the relationship between the two variables. It is determined by minimizing the sum of the squares of the differences between the observed values and the predicted values.

From the scatter plot, we can see that there is a positive correlation between the number of books read per month and the score on the SAT Verbal Test. This suggests that the more books a student reads per month, the higher their score on the SAT Verbal Test.

The equation of the line of best fit for the given data set is y = 6.4828x + 520.6962. Here, y represents the score on the SAT Verbal Test and x represents the number of books read per month.

To find the equation of the line of best fit, we can use a regression analysis tool such as Excel. The regression analysis will give us the values of the slope and intercept of the line of best fit, which we can use to write the equation of the line.

Answer:

Bill by $85

Step-by-step explanation:

Bill :  Compound interest is calculated by multiplying the initial principal amount by one plus the annual interest rate raised to the number of compound periods minus one. The total initial amount of the money given  is then subtracted from the resulting value.

Compounded annually for 6 years at 9 % interest Bill would have $8385.50.

Joe : Simple interest at 11% a year The formula we'll use for this is the simple interest formula.

P is the principal amount, $5000.00.

r is the interest rate, 11% per year, or in decimal form, 11/100=0.11.

t is the time involved, 6year(s) time periods.

So, t is 6year time periods.

To find the simple interest, we multiply 5000 × 11 × 6  = 3300

Usually now, the interest is added onto the principal to figure some new amount after 6 year(s),

or 5000.00 + 3300.00 = 8300.00

As you can see Bill has more by $85.
