To find the dimensions for which the area of a triangle is a maximum, we need to determine the base and height that satisfy the condition of the sum of base and height being 28 cm.

Let's denote the base of the triangle as 'b' and the height as 'h'. According to the given condition, we have the equation:

b + h = 28    (equation 1)

The formula for the area of a triangle is given by:

Area = (1/2) * base * height

Substituting 'b' and 'h' into the formula, the area of the triangle can be written as:

Area = (1/2) * b * h

To find the maximum area, we can use calculus. Let's solve equation 1 for 'h' in terms of 'b':

h = 28 - b

Substituting this expression into the area formula:

Area = (1/2) * b * (28 - b)

      = (1/2) * (28b - b^2)

      = 14b - (1/2) * b^2

To find the maximum area, we need to find the critical points of the area function. Taking the derivative of the area function with respect to 'b' and setting it equal to zero:

d(Area)/db = 14 - b = 0

Solving for 'b', we find b = 14. Substituting this value back into equation 1, we can find the corresponding height:

14 + h = 28

h = 14

Therefore, the dimensions for which the area of the triangle is a maximum are a base of 14 cm and a height of 14 cm.

(a) To find the Fourier transform of x1[n] = x[n - 1] + x[-1 - n], we can express it in terms of X(\(e^{jw}\)).

Using the time-shifting property of the Fourier transform, we have:

x1[n] = x[n - 1] + x[-1 - n]

X1(\(e^{jw}\)) = \(e^{jw}\)X(\(e^{jw}\)) + X(\(e^{-jw}\))

(b) To find the Fourier transform of x2[n] = x*[-n] * x[n + 1], we can also express it in terms of X(\(e^{jw}\)).

Using the time-reversal and time-shifting properties of the Fourier transform, we have:

x2[n] = x*[-n] * x[n + 1]

X2(\(e^{jw}\)) = X*(\(e^{-jw}\)) * \(e^{jw}\)X(\(e^{jw}\))

Answer:

\(m=\frac{-5}{3}\)

Step-by-step explanation:

We want to find the slope between the points (-2,5) and (1,0).

The slope (m) can be found using the formula \(\frac{y_2-y_1}{x_2-x_1}\), where \((x_1,y_1)\) and \((x_2,y_2)\) are points.

We are already given the values of the points, but let's label their values to avoid any confusion and mistakes.

\(x_1=-2\\y_1=5\\x_2=1\\y_2=0\)

Now, substitute into the formula.

\(m=\frac{y_2-y_1}{x_2-x_1}\)

\(m=\frac{0-5}{1--2}\)

Simplify this to:

\(m=\frac{0-5}{1+2}\)

\(m=\frac{-5}{3}\)

The slope is -5/3.

Answer:

System of equations:

5x + 20y = 425

x + y = 25

5 skates

20 bicycles

Step-by-step explanation:

Let x represent the number of skates and let y represent the number of bikes.

So each pair of skates costs $5 to rent and each bike costs $20 to rent. This means we can multiply the price of each time the amount of each we want to rent.

So, for the skates we would multiply 5 * x to get the total amount spent on skates.

Similarly for the bikes, we would multiply 20 * y to get the total amount spent on bikes.

We know that a total of $425 was spent on skates and bikes that day.

So, we can add the total amount spent on skates and the total amount spent on bikes to get the total amount spent that day (which we are told is $425).

Therefore, we have 5x + 20y = 425.

Since we've established that x represents the number of skates and y represents the number of bikes we can add x and y to find the total number of rentals that day (which we are told is 25).

Therefore we have x+ y = 25.

Finally we solve for x and y. I will be using the elimination method.

Step 1 - write down system of equations

(1) 5x + 20y = 425

(2) x + y = 25

Step 2 - multiply the second equation (2)  by -5 to eliminate x

-5(x+y=25)

which results in

(2) -5x - 5y = -125

Step 3 - rewrite system of equations using your new 2nd equation (2)

(1) 5x + 20y = 425

(2) -5x - 5y = -125

Step 4 - Add like-terms

Left hand side of equals symbol

5x + (-5x) = 0 (we have now eliminated x)

20y + (-5y) = 15y

Right hand side of equals symbol

425 + (-125) = 300

Since y was on the left side of the 2 equations we now have

15y = 300

Step 5 - Solve for y

15y = 300

We can divide both sides by 15 to isolate y, so

15y/15 = 300/15

which results in

y = 20

Since y represents the total number of bikes, we now know that 20 bikes were rented out that day.

Step 6 - Solve for x

Since we already have y, we can simply plug it into one of our original equations from our system of equations.

To make it simple, we can use our 2nd equation (2).

(2) x + y = 25

y = 20

x + 20 = 25

subtract 20 from both sides to isolate x.

so

x + 20 - 20 = 25 - 20

x = 5

Since x represents the total number of skates, we now know that 5 skates were rented out that day.

I'm sorry for the long explanation, but I wanted to make sure you understood the basics of creating and solving a system of equations. I used the elimination method, but I encourage you to check out the substitution method or ask your teacher about it if you haven't learned it in class yet.

Explanation:

1 hat = 45 dollars

6 hats = 6*45 = 270 dollars

1 phone = 40 dollars

4 phones = 4*40 = 160 dollars

total = $270 + $160 = $430

Felicia spent a total of $430. Since this amount of money leaves her account, this means we write a negative sign out front to end up with the final answer of -430

In other words, her account balance went down by $430 which is why we use a negative. If someone gave her $430, then the answer would be positive.

The range of the function y = 2sin(x) is the set of all possible values that the function can take. The range of the function y = 2sin(x) is [-2, 2].

In trigonometry, the sine function can be defined as the ratio of the length of the opposite side to that of the hypotenuse in a right-angled triangle. The sine function, sin(x), has a range between -1 and 1, inclusive. When we multiply the sine function by 2, as in the case of y = 2sin(x), the range is expanded.

Multiplying the range of sin(x) [-1, 1] by 2 gives us the range of 2sin(x), which is [-2, 2].

Therefore, the range of the function y = 2sin(x) is [-2, 2].

The diameter of a new ball is 4.0ft

According to the statement

we have given that the the company wants to spend a maximum of $1 each.

And we have to find a diameter of a new ball.

Remember that for a sphere of diameter D, the surface area is

A = 4*pi*(D/2)^2

In this case, the cost is $0.02 per square foot, and the company wants to expend (at maximum) $1 per ball, so first we need to solve:

$0.02*A = $1

A = $1/$0.02 = 50

So the surface of the ball must be 50 square feet.

Then we solve:

50ft^2 = 4*3.14*(D/2)^2

D = 2*√(50 ft^2/(4*3.14)) = 4.0 ft

here the diameter of a ball is 4.0ft.

Answer:

  (i) $1528.80

  (ii) $2402.40

  (iii) $41.39/h; 13.7% increase

Step-by-step explanation:

The weekly wage is found by multiplying hours by the number of dollars for each hour:

  weekly wage = (42 h)($36.40/h) = $1528.80

__

58 hours of work represents a straight week and 58 -42 = 16 hours of overtime. The overtime rate is 1.5×$36.40 = $54.60 per hour. Then the overtime pay is ...

  (16 h)($54.60/h) = $873.60

The technician's total wage for 58 hours of work is ...

  total wage = straight pay + overtime pay

  = $1528.80 +873.60

  total wage = $2402.40

__

The hourly rate is found by dividing the pay by the corresponding number of hours.

  rate = $1490/(36 h) ≈ $41.39 /h . . . . . . . actually 41.38 8/9 per hour

The percentage increase is ...

  ((new amount) -(original amount))/(original amount) × 100%

  = (4.98888...)/36.40 × 100% ≈ 13.7% . . . increase

Answer:

okay pues jjjjjjjjjjjj

Answer:

First, remember the definition of a vertical contraction/dilation.

If we have a function f(x), and we dilate it with a factor A, such as:

g(x) = A*f(x).

If A is larger than 1, then we are dilating the graph of f(x)

if A is smaller than 1, then we are contracting the graph of f(x).

In this case we have:

f(x) = x + 10 and g(x) = 0.3*f(x) = 0.3*x + 0.3*10 = 0.3*x + 3.

A = 0.3

then we have a contraction.

From this, we can conclude that the effects of this transformation in the graph will be that the graph of g(x) will be a vertical contraction of the graph of f(x).

(Where contracting means that in a given interval [x1, x2] the associated interval [f(x1), f(x2)] will be larger than [g(x1), g(x2)])

Below you can see both graphs, and see the difference between them, where green is f(x) and blue is g(x)

This is because the F-statistic for omitting BDR and Age from the regression is 0.08, which is less than the critical value for the test using the F-distribution table.

To test if the coefficients on BDR and Age are statistically different from zero, we compare the F-statistic with the critical value from the F-distribution table. The F-statistic is a measure of the overall significance of the regression model when certain variables are omitted.

In this case, the F-statistic is given as 0.08. To determine if the coefficients are statistically different from zero at the 5% level, we compare this value with the critical value from the F-distribution table. The critical value represents the threshold beyond which we reject the null hypothesis.

Based on the statement provided, it states that 0.08 is "less than the critical value." Since the F-statistic is smaller than the critical value, we can conclude that the coefficients on BDR and Age are not jointly significant at the 5% level. In other words, we fail to reject the null hypothesis that the coefficients are equal to zero.

The use of the phrase "jointly significant" implies that the significance of the coefficients is considered together, rather than individually. The test assesses the overall impact of BDR and Age on the regression model, rather than their individual effects. Since the F-statistic falls below the critical value, we do not have sufficient evidence to conclude that BDR and Age have a significant impact on the model.
