Answer:

Every polygon is either convex or concave. The difference between convex and concave polygons lies in the measures of their angles. For a polygon to be convex, all of its interior angles must be less than 180 degrees. Otherwise, the polygon is concave.

Convert into percentages 7/25

LekaFEV [45]

Answer:

28%

Step-by-step explanation:

Divide the numerator by the denominator in order to convert this fraction into a decimal.

7/25 = 0.28

Multiply the decimal by 100 to convert into a whole number.

.28 * 100 = 28

7/25 converted into a percent is 28%.

Find the values of a and b that make the second expression equivalent to the first expression. Assume that x > 0 and y ≥ 0. S

mixas84 [53]

Answer:What was done from the first to the second equation was that the fraction was simplified. 126 and 32 have a common factors of 2.

126/32=(63*2)/(16*2)

The 2s in the top and bottom can cancel out, leaving the fraction 63/16.

In addition, since there are x terms on the top and bottom, they cancelled out as well.

x/x^3=1/x^2

This leaves an x^2 term on the bottom.

Thus, if a is 16, and b is 2, you will have an equivalent form of the fraction.

A line passes through the points (p, a) and (p, –a) where p and a are real numbers and p ≠ 0. Describe each of the following. Ex

MissTica

Answer:

Part A) The slope is undefined

Part B) The equation of the line is $x=p$

Part C) None y-intercept

Part D) The slope of a line perpendicular to the given line is equal to zero

Step-by-step explanation:

we have that

Describe

A) slope of the line

B) equation of the line

C) y-intercept

D) slope of a line perpendicular to the given line

Part A) slope of the line

we know that

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have

$(p,a)\ (p,-a)$

Substitute the values

$m=\frac{-a-a}{p-p}$

$m=\frac{-2a}{0}$ -----> the slope is undefined

Its a vertical line (parallel to the y-axis)

Part B) Equation of the line

we know that

The equation of a vertical line is equal to the x-coordinate of the points through which the line passes.

$x=p$

Part C) The y-intercept

The y-intercept is the value of y when the value of x is equal to zero

The vertical line not intercept the y-axis

None y-intercept

Part D) slope of a line perpendicular to the given line

A line perpendicular to the given line is a horizontal line (parallel to the x-axis)

therefore

The slope is equal to zero
