can someone please help me​

Answer:

1. The area is found by using the formula for a rectangle

The area is 150 cm²

2. The area is found by the definite integral for the area between two points under a curve

3. The methods are different

The methods are different because the area of figure A is found by the multiplication between the dimensions, while the area of figure B is found by the difference between the values of the integral of the function between the points

Step-by-step explanation:

1. The area of the shaded figure A is found by multiplying the dimensions of the figure, which is the length multiplied by the breadth of the figure

From the question, we have;

The area of the rectangular figure, A = Length × Breadth

The length of the figure = 15 cm

The breadth of the rectangular figure = 10 cm

Therefore, we have;

A = 15 cm × 10 cm = 150 cm²

The area of the rectangular figure, A = 150 cm²

2. The bell shape of the figure B is obtained from a function f(x) as obtained from MIT mathematics website as follows;

[tex]f(x) = e^{-t^2}[/tex]

Therefore the area of the shaded region in the bell shaped figure between the points 0 and 1 on the x-axis is found by integration as follows;

[tex]A = \int\limits^1_0 {e^{-t^2}} \, dt = \dfrac{1}{2} \cdot \sqrt{\pi} \times erf(t)[/tex]

Using a graphing calculator, we have;

[tex]A = \int\limits^1_0 {e^{-t^2}} \, dt \approx 0.746824[/tex]

3. The method of finding the area of figure A is different from the method of finding the area of the figure B

The methods are different because the area of figure A is the area of the whole figure of a geometric shape with known formula for area while the area of of the shaded region has no predefined formula but is calculated using the calculus for the area under a curve.

Original price of jeans=$50

Since there is a discount of 30%

So we take 100%-30%=70%

hence to find the price Justin have to pay after discount, we take $50x70/100=$35

Therefore Justin has to pay $35 for the jeans after discount.

Answer:

1188 inches

Step-by-step explanation:

Answer:

The surface area of the cylinder with a radius of 7 and height of 20 would be 1186.92.

Step-by-step explanation:

The formula as given by the image is

h=20, r=7.

Substitute your radius and height as follows:

SA=[tex]SA=2*pi*r^2+2pi*r*h\\(2*3.14*7^2)+(2*3.14*7*20)[/tex]

And now solve!

307.72+879.2=1186.92

The answer would be 1186.92

Step-by-step explanation:                  180 bagels

The unit rate, in bagels per hour, is ---------------------- = 36 bagels/hour

                                                                 5 hours

In 22 hours, the bakery can bake (36 bagels/hour)(22 hours) = 792 bagels

Answer:

Step-by-step explanation:

Answer:

Given that the manufacturers claim is true, the probability that the sample mean area is 249.6 ft.² or less is 0.42074

Step-by-step explanation:

The manufacturer claims that mean amount of foil on each roll, μ = 250 ft²

The standard deviation of the measured amount of foil per roll, σ = 2 ft.²

The number of rolls tested by the restaurant, n = 10 rolls

The mean measured by the restaurant, [tex]\overline x[/tex] = 249.6

Taking the sample means as individual score, we have;

The z-score, of the sample mean is given as follows;

[tex]z=\dfrac{\overline x -\mu }{\sigma }[/tex]

At [tex]\overline x[/tex] = 249.6, we have;

z = (249.6 - 250)/2 = -0.2

Therefore, the probability for a mean less than or equal to 249.6, we have;

The probability, P = P(z < -0.2) = 0.42074

The probability that the sample mean area is 249.6 ft.² or less given that the manufacturers claim is true, P = 0.42074.

Answer:

Both rectangles and squares have four sides of equal length.

Step-by-step explanation:

Rectangle and square are the geometrical figures having four sides. They are the quadrilaterals with four sides. A rectangle is the quadrilateral in which opposite sides are equal. In a square all the sides are of equal length. The sides of both the rectangle and square are parallel. All angles form the right angles.

Answer:

136

Step-by-step explanation:

The sum of interior angles of a polygon is (n-2)x180 where n is the no. of sides. Here n=5 Therefore sum of int. angles = (3-2)x180= 3x180=540.

Sum of all given angles =404.

Remaining angle= 540-404=136

Answer:

B

Step-by-step explanation:

We are given that:

[tex]8x-3, \, 4x+1, \text{ and } 2x-2[/tex]

Are consecutive terms of an arithmetic sequence.

And we want to determine the common difference d.

Recall that for an arithmetic sequence, each subsequent term is d more than the previous term.

In other words, the second term is one d more than the first term. So:

[tex]4x+1=(8x-3)+d[/tex]

And the third term is two d more than the first term. So:

[tex]2x-2=(8x-3)+2d[/tex]

We can isolate the d in the first equation:

[tex]-4x+4=d[/tex]

As well as the second:

[tex]-6x+1=2d\Rightarrow \displaystyle -3x+\frac{1}{2}=d[/tex]

Then by substitution:

[tex]\displaystyle -4x+4=-3x+\frac{1}{2}[/tex]

Solve for x:

[tex]\displaystyle -x=\frac{-7}{2}\Rightarrow x=\frac{7}{2}[/tex]

The isolated first equation tells us that:

[tex]d=-4x+4[/tex]

Therefore:

[tex]\begin{aligned} \displaystyle d&=-4\left(\frac{7}{2}\right)+4\\&=-2(7)+4\\&=-14+4\\&=-10 \end{aligned}[/tex]

Our final answer is B.

Answer:

B.) - 10 is the answer.

Step-by-step explanation:

Given :

Two numbers 25 and 17.

How much larger is the sum of the numbers 25 and 17 compared to their difference? (Two small brackets will be used.)

To Find :

How much larger is the sum of the given numbers as compared to their difference.

Solution :

Sum of given numbers, S = 25 + 17 = 42 .

Difference of given numbers, D = 25 - 17 = 8 .

The difference between S and D is, S - D = 42 - 8 = 34 .

Therefore, sum of the numbers is larger by 34 than in difference.
