When two rays are put together it forms an angle (because of the three points)

myrzilka [38]2 years ago

Sample Response: An angle is defined as two rays with a common endpoint, so CAB (or BAC) is an angle. A line is described as an infinite set of points that extend forever in either direction, which these rays also do.

Find an equation in rectangular coordinates for the cylindrical equation r = 2sintheta

frutty [35]

Answer:

$x^2+(y-1)^2=1$

Step-by-step explanation:

The given cylindrical equation is

$r=2\sin \theta$

Multiply both sides by r.

$r^2=2r\sin \theta$ .... (1)

The required formulas are

$x=r\cos \theta,y=r\sin \theta,r^2=x^2+y^2$

Substitute $r\sin \theta =y,r^2=x^2+y^2$ in equation (1).

$x^2+y^2=2y$

$x^2+y^2-2y=0$

Add 1 on both sides.

$x^2+(y^2-2y+1)=1$

$(x-0)^2+(y-1)^2=1^2$ $[\because (a-b)^2=a^2-2ab+b^2]$

It is the equation of a circle centered at (0,1) with radius 1.

Therefore, the equation in rectangular coordinates is $x^2+(y-1)^2=1$ .

9. What value of m makes this equation true? 1/2 (8m - 18) = 31

OverLord2011 [107]

Answer:

m = 10

Step-by-step explanation:

The value of m that would make this equation true is 10. To figure this out you must work the equation to combine like terms. To start, remember PEMDAS. You would begin with 1/2 (8m - 18) and multiply both 8m and 18 by 1/2. Because half of 8 is 4 and half of 18 is 9, your new equation would be 4m - 9 = 31. From here you would add nine to both sides to finish combining like terms. The equation from this point should be 4m = 40. To find the value of m, you then have to divide both sides by 4, leading to the equation/solution of m = 10.

Which is greater 3 decimeters or 30 centimeters

MatroZZZ [7]

One decimeter equals 10 centimeters. So 3 decimeters equals 30 centimeters. They are equal.
