All the radii of a circle have the same length? True or False

Mathematics

skad [1K]3 years ago

Answer with explanation:

→General equation of circle is :

 (x-a)^2+(y-b)^2=r^2

having center, (a,b) and radius =r units.

→If the center , of the circle is at Origin (0,0) and have radius equal to r units the equation of circle will be:

x² + y²=r²

Radius= Distance from the center to any point on the circle,which is same for that circle.

⇒So, Yes , With Conformity,All the radii of a circle have the same length is a true Statement.

True

Note that sum of triangle interior angles is 180. So,

(12x+12)+15+(3x+18)=180

15x+45=180

15x=135

x=9

Since A=12x+12=12.9+12=120

And C=3x+18=3.9+18=45

Which equation matches the given points? (0, 7.6), (1, 6.2), (2, 4.8), (3, 3.4), (4,2)
Cerrena [4.2K]

The equation that matches the given points is g(x) = -1.4x + 7.6

The standard form of a linear  equation is expressed as g(x)=mx + b

  • m is the slope of the line
  • b is the y-intercept:

Using the coordinate points (3, 3.4), (4,2)

m=\frac{2-3.4}{4-3}\\m=\frac{-1.4}{1}\\m=-1.4

Substitute m = -1.4 and the coordinate (4, 2) into the formula:

2=4(-1.4)+b\\2=-5.6+b\\b=2+5.6\\b=7.6

Get the required equation:

g(x)=mx+b\\g(x)=-1.4x+7.6

Hence the equation that matches the given points is g(x) = -1.4x + 7.6

Determine the end behavior of each rational function below. Graph each function on the graphing calculator, and
melomori [17]

Answer:

a) End behavior: As → ∞, () → . As → −∞, () → .

Looking at the ends of the graph, as goes to ∞ or −∞, gets

closer to .

b) End behavior: As → ∞, () → . As → −∞, () → .

Looking at the ends of the graph, as x goes to ∞ or −∞, gets

closer to .

c) End behavior: As → ∞, () → ∞, and as → −∞, () → −∞.

Looking at the ends of the graph, as goes to ∞, continues to increase

toward ∞, and as x goes to −∞, continues to decrease toward −∞.

Help me with this please
meriva

Answer:

1) E

2) D

3) G

4) I

Step-by-step explanation:

1)

P = 2(l + w)

P = 2(3a + 3 + 8a - 12)

P = 2(11a - 9)

P = 22a - 18

2)

P = 22a - 18

P = 22(3) - 18

P = 66 - 18

P = 48

3)

P = a + b + c

P = 3b + 7 + 7b - 2 + 7b - 2

P = 17b + 3

4)

P = 17b + 3

P = 17(6) + 3

P = 102 + 3

P = 105
