IS this table linear?? Can someone please explain???? What would the weight be if the number of weeks in the fitness program was
boyakko [2]

Answer:

  • not linear
  • somewhere between 184 and 186 (maybe)

Step-by-step explanation:

As you show, the weight differences are different for the same week differences, so the table is not linear. A graph (attached) can also show you the table is not linear.

__

The highest rate of weight loss shown in the table is 7 lbs in 3 weeks, or 4 2/3 pounds in 2 weeks. The lowest rate of weight loss shown in the table is 5 lbs in 3 weeks, or 3 1/3 pounds in 2 weeks. Based on the rates shown in the table, we might expect the starting weight to be between 3 1/3 and 4 2/3 pounds more than the first table value:

  Week 0 weight: between 184 1/3 and 185 2/3 lbs, estimated.

_____

A "line of best fit" for the data has a y-intercept of about 185 pounds, which is the midpoint between our two estimates above.

• How do you use the distance formula and slope formula to prove properties of polygons?
patriot [66]

Answer:

distance formula= \sqrt{x} (x_{2} -x_{1} )^{2} + (y_{2} -y_{1} )^{2} = find the length(units) using coordinates.

slope formula= m=\frac{rise}{run} =\frac{y_{2}-y_{1}  }{x_{2} -x_{1} }= determines slope of a line using two points on the line(coordinates)

When working with polygons the main properties which are important are:

The number of sides of the shape.

The angles between the sides of the shape.

The length of the sides of the shape.

length , width

straight lines , angles, vertices, vertex

A polygon is any 2-dimensional shape formed with straight lines.

a plane figure with at least three straight sides and angles, and typically five or more.

Step-by-step explanation:

<h2><u>answer= use distance and slope to determine that opposite side of a polygon are the same length and same slope</u></h2>

A car travels 32 miles for each gallon of gas. How many gallons of gas does it need to travel 192 miles.
Aleks [24]

Your answer is 6 gallons of gas.

Since the car can travel 32 miles per gallon(mpg), you would need to do 192 divided by 32 to get your answer. To verify it you can do 6(answer) times 32. Your answer would be 192, meaning you're right.
