Determine whether y varies directly with x. If so, find the constant of variation and write the equation. yes; k = 1/4 and y = 1/4x

No

yes; k = 4 and x - 4y

yes; k = 4 and y - 4y

Answers

Answer:

Yes, 4 and  y = 4x

Step-by-step explanation:

By looking at the graphic you see it's a straight line, not a hyperbolic curve, not a logarithm curve either, not a curve at all in fact.  And the line is neither totally horizontal nor totally vertical... so there's a direct relation, a direct positive relation, since the greater the x-value, the greater the y-value.

Then we have to find the constant of variation, or the slope of the line.

We'll take two points on the line (1,4) and (0,0) and examine their variance of Y over their variance of X... that will give us the constant of variation:

slope = (4-0)/(1-0) = 4

So the constant of variation is 4.

Now that we have the slope, its easy to find the full equation:

y = mx + b where m is the slope (we have it) and b is the value for y when x = 0.

By looking at he graph, we see that when x = 0, y = 0 as well.

So, the equation is: y = 4x

tour takes his dog to be groomed. The fee to groom the dog is $75 plus 6.75 % tax. Is $80 enough to pay for the service? explain

Answers

Tour takes his dog to get groomed on a budget of $80

Now the fee to groom the dog is $75 plus 6.75% tax. 
The question asks if the budget is enough to cover the fee.

lets find the total cost:

$75 + ($75 x 0.0675)
= 75 + 5.06
= 80.06

$80 is not enough to pay for the dog to get groomed 

Find the perimeter and the area of the polygon with the given vertices. W (11,2), X (11,8), Y (14,8), Z (14,2)

Answers

Answer:

The perimeter of the polygon = 18 units

The area of the polygon will be A=18 square units

Step-by-step explanation:

Computing the Perimeter of the Polygon:

Considering the polygon with vertices

  • W (11,2)
  • X (11,8)
  • Y (14,8)
  • Z (14,2)

As the polygon is drawn in coordinate plane as shown in figure a.

From the attached figure a, we can observe that

  • The length of the side WZ = 3 units
  • The length of the side ZY = 6 units
  • The length of the side WX = 6 units
  • The length of the side XY = 3 units

So, the perimeter of the polygon can be calculated by taking the sum of the lengths of all sides i.e.

The perimeter of the polygon = WZ + ZY + WX + XY

                                                  = 3 + 6 + 6 + 3

                                                  = 18 units

Computing the Area of the Polygon:

Area can be calculated by multiplying the length and width of the polygon.

A=lw

So, the area will be:

A=lw

A=(3)(6)

A=18

Therefore, the area of the polygon will be A=18 square units

Look at this prism and its net. Rectangular prism with length labeled 5 meters, width labeled 7 meters, and height labeled 12 meters. Net of the same rectangular prism with the same dimensionsn labeled. What is the surface area of this rectangular prism?

Answers

There will be three pairs of matching sides: one pair 5x7, one pair 5x12 and one pair 12x7. We can compute the are of each side (in pairs) and then add up the total:

A_(surf)=2*(l * w)+2*(l * h)+2*(h * w)
A_(surf)=2*(5*7)+2*(5*12)+2*(12*7)
A_(surf)=2*35+2*60+2*84
A_(surf)=70+120+168
A_(surf)=358 
A_(surf)=358m^(2)
