Only regular polygons with an even number of sides are symmetrical? True or false?

Answers

Answer 1

Answer:

Answer:

The given statement:

Only regular polygons with an even number of sides are symmetrical is a FALSE STATEMENT.

Step-by-step explanation:

A symmetrical figure or a polygon means that if it is into halves such that the halves looks similar or match exactly then the figure is said to be symmetrical.

We know that a regular polygon with 'n' number of sides has exactly n number of axis of symmetry.

Hence, no matter whether the regular polygon has even number of sides or odd number of sides it will be symmetrical.

Answer:

Answer: false

took the quiz

C.) y + 5 = 7(x - 9)

Step-by-step explanation:

Parallel lines have the same slope.

The slope-intercept form of an equation of a line:

y = mx + b

m - slope

b - y-intercept

The point-slope form of an equation of a line:

y - y₁ = m(x - x₁)

(x₁, y₁) - point on a line

m - slope

We have the line y - 9 = 7(x + 5). The slope m = 7.

A) y - 9 = 3x + 4 → m = 3

B) y = -9x - 5 → m = -9

C) y + 5 = 7(x - 9) → m = 7

D) y - 9 = 5(x + 4) → m = 5

The line C) y + 5 = 7(x - 9) has the same slope.

Does the parabola open up or down? Is the y-coordinate of the vertex a minimum value or a maximum value?f(x) = 5x^2-x

Answers

it opens up and the y coordinate of the vertex is a minimum value!

Circle d has a radius of 21 millimeters and central angle, ∠edf, which measures 60°. find the exact length of . mm 7mm 14mm 42mm

Answers

the length of an arc length can be calculated using the formula:
s = ra
where s is the lenght of the arc
and r is the radius of the circle
a is the central angle in radians

first converts degrees to radians
a = 60 ( pi / 180)
a = pi /3 =1.05

s = 21(1.05)
s = 22 mm is the length of the arc

Answer:

7π mm

researchers wish to test the effect of living environment on cholesterol level they take a sample of people from a rural area and a sample of people from an urban area and compare their cholesterol levels. what would be the best statistical test for them to utilize? group of answer choices two-sample t-test anova linear regression chi-square

Answers

To test the effect of living environment on cholesterol levels using samples from rural and urban areas, the best statistical test to utilize would be the two-sample t-test.

The two-sample t-test is appropriate in this case because it compares the means of two independent groups (rural and urban residents) to determine if there is a significant difference between their cholesterol levels.

This test will help researchers determine if living environment has an impact on cholesterol levels.
