Answer:

percentage change= 500%

Step-by-step explanation:

After diet the weight reduced = 30 pounds

Before diet her weight = 180 pounds

percentage change = { (180 - 30) ÷ 30 } × 100

                             =  ( 150 ÷ 30) × 100

                              = 5 × 100

                               = 500 %

∴percentage change= 500%

What is the equation of the line that passes through the point (3,4) and has an undefined slope?
rosijanka [135]

Answer:

The equation of the line that passes through the point (3,4) and has an undefined slope is x = 3

Step-by-step explanation:

  • The slope of the horizontal line is zero
  • The equation of the horizontal line passes through the point (a, b) is y = b
  • All the points on the horizontal line have the same y-coordinates

  • The slope of the vertical line is undefined
  • The equation of the vertical line passes through the point (a, b) is x = a
  • All the points on the vertical line have the same x-coordinates

Let us solve the question

∵ The line has an undefined slope

∴ The line is a vertical line

∵ The equation of the vertical line is x = a, where a is the x-coordinate

   of any point on the line

∵ The line passes through the point (3, 4)

∴ a = 3

∴ The equation of the line is x = 3

The equation of the line that passes through the point (3,4) and has an undefined slope is x = 3

What radius of a circle is required to inscribe a regular hexagon with an area of 166.28 in2 and an apothem of 6.928 in?
Lunna [17]
If you want to inscribe a polygon inside a circle, you have a formula that doesn't have to use the apothem. The formula is:

A = (nr²/2)sin(360/n)

Since the polygon is a hexagon, it has 6 sides. Thus, n = 6. Knowing the area, we can determine the radius of the circle, r.

166.28 = (6r²/2)sin(360/6)
r = 8 inches

Thus, the radius of the circle is 8 inches.
