How do you find the circumference of a cirlcle?

yKpoI14uk [10]

There are 2 formula to find the circumference of a circle.

$\huge{\boxed{\bf{Circumference=2\pi r}}}$

$\huge{\boxed{\bf{Circumference=\pi D}}}$

$\pi$ is approximately 3.14
r is radius
D is diameter

and just a side note, $\huge{\boxed{\bf{2 r = D}}}$
Hope that formula helps you :)

Which function has a range of all real numbers greater than or equal to -4?

max2010maxim [7]

Answer:

C. $f(x)=(x+1)^2-4$

Step-by-step explanation:

A. the graph is a straight line with slope 1. It goes up/down infinitely far so the range is all real numbers. Not A!

B. The graph is a straight line with slope -4, so, like the function in A, the range is all real numbers. Not B!

D. The graph is an absolute value function y = |x|, reflected over the x-axis, shifted right 3 units, then shifted down 4 units. So the graph starts witha "vee" shape opening up, becomes a vee opening <u>down</u>, then ultimately gets shifted down 4 units. The range is all real numbers less than or equal to -4.

See the attached graphs. image2 is the function in answer choice D.

Please help me i will give brainlest please i need help

Answer:

Since you didn't mention which question.

Step-by-step explanation:

13.

$1.\overline{52}\\$ = 1.525252...

Let x = 1.525252...

10x = 15.2525252....

100x = 152.525252...

100x - x = 151.00

99x = 151

$x = \frac{151}{99}\\\\or\\\\x = 1 \frac{52}{99}$

14.

4x + 10 = 8x - 26 [ corresponding angles are congruent ]

4x - 8x = - 26 - 10

- 4x = - 36

$x = \frac{-36}{-4} \\\\x = 9$

15.

Given breadth of a rectangle is ( 2/3) its length.

Let the length be x

Therefore, breadth = ( 2 /3) of x

$= \frac{2}{3} \times x\\\\=\frac{2}{3}x$

Given perimeter = 40m

Perimeter of a rectangle = 2( length + breadth)

$40 = 2 (x + \frac{2}{3}x )\\\\\frac{40}{2} = \frac{2}{2}(x + \frac{2}{3}x)\\\\20 = x + \frac{2}{3}x\\\\20 = \frac{3x + 2x}{3}\\\\20 \times 3 = 5x \\\\x = \frac{60}{5}\\\\x = 12\\\\Therefore, Length = x = 12 \ m \ and \ breadth = \frac{2}{3}x = \frac{2}{3} \times 12 = 8 \ m$

16.

Sum of the angles of a triangle = 180°

Given ratio = 2 : 3 : 4

Sum of the ratio = 9

Therefore,

$first \ angle = \frac{2}{9} \times 180 = 2 \times 20 = 40 ^\circ\\\\Second \ angle = \frac{3}{9} \times 180 = 3 \times 20 = 60^\circ\\\\Third angle = \frac{4}{9} \times 180 = 4 \times 20 = 80^\circ$

17.

Sum of interior angles of a polygon with n sides = ( n - 2) x 180°

Given polygon is pentagon, that is n = 5

Therefore, sum of the interior angles = ( 5 - 2) x 180 = 3 x 180 = 540°

That is ,

x + 125 + 125 + 88 + 60 = 540°

x + 398 = 540°

x = 540 - 398

x = 142°
