Step-by-step explanation:

Answer:

Step-by-step explanation:

This problem is on the mensuration of flat shapes, sectors and arc.

we know that the area of a sector is given as

A=(∅/360)*πr^2

Given that the length of the wiper R=24 in

and the length of the blade r= 16in

To find the area of the wiped surface we only require the length of the blade as the radius

The area of the wiped surface is given as= (140/360)*3.142*16^2

A= 0.3888*3.142*256

A=312.7 in^2

Answer:

1)[tex]h = \frac{3V}{\pi {r}^{2} }[/tex]

2)[tex]b = \frac{a}{2} + 2[/tex]

3)[tex]y = \frac{w - 3x}{7} [/tex]

Step-by-step explanation:

1)[tex]V= \frac{1}{3} \pi {r}^{2} h[/tex]

[tex] = > V = \frac{ \pi {r}^{2} h}{3} [/tex]

[tex] = > 3V = \pi {r}^{2} h[/tex]

[tex] = > h = \frac{3V}{\pi {r}^{2} } [/tex]

2)[tex]a=2(b-c)[/tex]

[tex] = > \frac{a}{2} = b - c[/tex]

[tex] = > b = \frac{a}{2} + c[/tex]

3)[tex]w=3x+7y[/tex]

[tex] = > w - 3x = 7y[/tex]

[tex] = > y = \frac{w - 3x}{7} [/tex]

By the product rule,

[tex](fg)'=f'g+fg'[/tex]

so that

[tex](fg)'(7)=f'(7)g(7)+f(7)g'(7)=10\cdot(-1)+4\cdot8=22[/tex]

By the quotient rule,

[tex]\left(\dfrac fg\right)'=\dfrac{f'g-fg'}{g^2}[/tex]

so that

[tex]\left(\dfrac fg\right)'(7)=\dfrac{f'(7)g(7)-f(7)g'(7)}{g(7)^2}=\dfrac{10\cdot(-1)-4\cdot8}{(-1)^2}=-42[/tex]

Answer:

[tex]\boxed{\tt m=0}[/tex]

Step-by-step explanation:

The slope formula is:

[tex]m=\frac{y_{2} -y_{1}}{x_{2}-x_{1}}[/tex]

where (x₁, y₁) and (x₂,y₂) are the points on the line.

The points given are (-2,8) and (-22,8). Therefore,

[tex]x_{1}=-2\\y_{1}=8\\x_2=-22\\y_2=8[/tex]

Substitute the values into the formula.

[tex]m=\frac{8-8}{-22--2}[/tex]

Solve the numerator. Subtract 8 from 8.

[tex]m=\frac{0}{-22+2}[/tex]

Zero divided by any number is zero, so we automatically know the slope is zero.

[tex]m=0[/tex]

The slope of the line is 0

Answer: 0

Step-by-step explanation:

To find the slope, you need to use the formula [tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]. You use the given points to plug in and solve.

[tex]m=\frac{8-8}{-22-(-2)} =\frac{0}{-20}=0[/tex]

Now, we know that the slope is 0 meaning this is a horizontal line.

Answer:

the comparisms between pairs of scores

Step-by-step explanation:

The sign test can also called statistical test , this test is essential in the determination of group size. It also give comparisms between the given value and median of datas

It should be noted that The statistic used in the sign test measures the comparisms between pairs of scores

Answer:

the roots are {-4/3, 4/3}

Step-by-step explanation:

Begin the solution of 11=6|-2z| -5 by adding 5 to both sides:

11=6|-2z| -5 becomes 16 = 6|-2z|.

Dividing both sides by 12 yields

16/12 = |-z|

There are two cases here:  first, that one in which z is positive and second the one in which z is negative.

If z is positive, 4/3 = -z, and so z = -4/3, and:

If z is negative, 4/3 = z

Thus the roots are {-4/3, 4/3}

Answer:

X=70

Step-by-step explanation:

Interior angles of parallel line sum up to be 180° so:

45+(2x-5)=180

45+2x=185

2x=140

x=70

Answer:

The cost function of manufacturing this box is:

[tex]C_{T} = 2.15\cdot x^{2}+30\cdot x[/tex], where [tex]x[/tex] is the length of the box, measured in US dollars.

Step-by-step explanation:

From the statement we know that:

1) The box has a square base ([tex]w = l = x[/tex]).

2) The box has a depth of 10 inches ([tex]h = 10\,in[/tex]).

3) The cost of manufacturing the top of the box is $ 1.20 per square inch.

4) The cost of manufacturing the bottom of the box is $ 0.95 per square inch.

5) The cost of manufacturing each side of the box is $ 0.75 per square inch.

The total cost of manufacturing the box is:

[tex]C_{T} =C_{bottom} + C_{top} + 4\cdot C_{side}[/tex]

Where:

[tex]C_{bottom}[/tex] - Cost of the bottom of the box, measured in US dollars.

[tex]C_{top}[/tex] - Cost of the top of the box, measured in US dollars.

[tex]C_{side}[/tex] - Cost of the side of the box, measured in US dollars.

Dimensionally, cost equals unit cost, measured in US dollars by square inch, multiplied by surface area, measured in square inches. Now, the expression is expanded:

[tex]C_{T} = c_{bottom}\cdot x^{2}+c_{top}\cdot x^{2}+4\cdot c_{side}\cdot h\cdot x[/tex]

[tex]C_{T} =(c_{bottom}+c_{top})\cdot x^{2}+4\cdot c_{side}\cdot h \cdot x[/tex]

If we know that [tex]c_{bottom} = \$\,0.95\,in^{-2}[/tex], [tex]c_{top} = \$\,1.20\,in^{-2}[/tex], [tex]c_{side} = \$\,0.75\,in^{-2}[/tex] and [tex]h = 10\,in[/tex], the cost function of manufacturing this box is:

[tex]C_{T} = 2.15\cdot x^{2}+30\cdot x[/tex], where [tex]x[/tex] is the length of the box, measured in US dollars.

Answer:

d does not have an inverse image

Step-by-step explanation:

From the question we are told that

    The  first set is    A (10, 11, 12, 13 )

     The  second set is     B (a, b, c, d)

      The function that from A to B is  f(10, a), (11,a), (12, b), (13,b))

Generally for a function defined by (x,y), y is the image of x while x is the inverse image  of  y

Now considering the function we are given and the value d we see that and inverse image is not defined for d in the function

hence d does not have an inverse image

Answer:

x = 95 degrees

Step-by-step explanation:

if you add the two angles that are right across each other, it should equal 180 degrees, so you subtract 180 and 85 to get 95 degrees

The correct answer is C. The 13 moose are the individuals. There is one categorical variable and four quantitative variables.

Explanation:

In research, the individuals refer to the participants or population that is being analyzed. For example, if the purpose of the research is to know how many hours highschool students sleep, the individuals are high school students. In this context, the individual or population of this study ae the 13 moose.

Moreover, this research focuses on different variables such as gender, height, the number of hours each moose spends in the water, the weigh of the food eaten on average by each moose, and the average weight of food eaten every day. From these variables, the last four variables are quantitative because they can be measured using numbers, for example, the height is measured in inches. On the other hand, the first variable is categorical because each moose can be classified in only two categories: male or female.
