C) 574.53 foot-pounds

Step-by-step explanation:

got it right on edge :)

Awagon is being pulled by a force of 15 pounds.  the required work done is 574.53 to pull the wagon So, Option C) is correct work done = 574.53.

The work done is product of force and cosine of displacement.

Given; Awagon is being pulled by a force of 15 pounds. We need to find How much work is done in moving the wagon 50 feet if the handle makes an angle of 40° with the ground.

Force = 15 pounds

distance = 50 feet

Ф = 40°

We can calculate the work done as;

work done = force x displacement x cosФ

work done = 15 x 50 x cos40

work done = 15 x 50 x 0.76

work done = 574.53

Therefore, the required work done is 574.53 to pull the wagon.

Answer:

The average rate of change on the given interval is 9/70

Step-by-step explanation:

Here, we are to find the average rate of change of the function on the given interval

We proceed as follows;

on an interval [a,b] , we can find the average rate of change using the formula;

f(b) - f(a)/b-a

From the question;

a = 0

b = 3

f(0) = -3/5

f(3) = -3/14

Substituting the values, we have;

-3/14-(-3/5)/3-0

= 3/5-3/14/3

= (42-15)/70/3

= 27/70/3

= 27/70 * 1/3 = 9/70

Answer:

-9x+7

Step-by-step explanation:

The solution to the equation given as x+2/2x-6 = 3/8 is x = -34/5

Expressions are mathematical statements that are represented by variables, coefficients and operators

The equation is given as

x+2/2x-6=3/8

Apply the multiplication property of equality.

So, we have

8(x + 2) = 3(x - 6)

Open the brackets

8x + 16 = 3x - 18

Collect the like terms

5x = -34

Divide both sides by 5

x = -34/5

Hence, the solution to the equation given as x+2/2x-6 = 3/8 is x = -34/5

Answer:

y = 65x + 250

Step-by-step explanation:

Let the linear equation representing the relation between total pay and number of computers sold be,

y = mx + c

Here, m = commission on every computer sold = slope of the linear function

c = weekly salary

y = total pay

x = number of computer sold each week

Since, slope of the line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

From the table attached,

Slope of the line passing through (4, 510) and (6, 640),

m = [tex]\frac{640-510}{6-4}[/tex]

   = 65

Equation of the line will be,

y = 65x + c

Since, this line passes through (4, 510),

510 = 65(4) + c

c = 510 - 260

c = 250

Therefore, equation of the line will be,

y = 65x + 250

Answer:

I will not give you an answer, but I will give you how too get the equation started.

Step-by-step explanation:

set up an equation using:

x= amount invested at 3%

7800 - x = amount invested at 12%

.03(x) + .12(7800 - x) = 504

.03x +936 - .12x = 504

-.09x = -432

x = 4800

Step-by-step explanation:

Answer:

1. x = 1.5 rpm

2. x ≈ 0.8182 mi/hr

3. x = 6.6 feet

4. x = 4224 rpm

5. x = 390 rpm

Step-by-step explanation:

The relationship between angular speed and linear speed is given as follows;

Angular speed, ω = Linear speed, v/(Radius, r)

Therefore, we have;

1. When v = 12 cm/min = r = 8 cm , ω = 12/8 = 1.5 rpm

2. When, ω = 4 rpm, and  r = 18 feet, v = 4 × 18 = 72 feet/min ≈ 0.8182 mi/hr

3. When, ω = 800 rpm, and v = 60 mi/hr = 1 mi/min, r = x = 1/800 miles = 6.6 feet

4. When v = 60 mi/hr = 63,360 mi/min, r = 15 in , ω = 63360/15 = 4224 rpm

5. When v = 13 in/sec = 780 in/min, r = 2 in, ω = 780/2 = 390 rpm

Answer:

The points from the left;

71, 74 , 77, 80, 83, 86 , 89

Step-by-step explanation:

Here, we want to label the normal curve given the mean and the standard deviation

From what we have, the central part is the mean while the other parts are deviations from the mean

We will label the graph starting from the left to the right

1 is 3 SD from the mean (negatively)

That will be 80-3(3) = 80-9 = 71

2 is 2 SD away

That will be;

80 -2(3) = 80-6 = 74

The 3rd part is 1 SD away

That will be 80-3 = 77

The midpoint is for the mean which is 80

The point after this will be;

80 + 3 = 83

The point after this will be;

83 + 3 = 86

Next is

86 + 3 = 89

D. x=1

Step-by-step explanation:

Image can be rewritten as 3x + 6 = 9.

Solve for x.

Isolate x by subtracting 6 from both sides.

3x = 3

Get rid of the 3 by dividing by 3 on both sides.

x = 1

The vertical translation is 1 unit upward, and there is no horizontal translation. So, the function will be something of the form ...
