Mathematics

AysviL [449]2 years ago
3 0

- 12 = x +  \frac{8}{ - 3}

- 12 - ( \frac{8}{ - 3} ) = x

- 12 -  \frac{8}{3}  = x

\frac{ - 36}{3}  -  \frac{8}{3}  = x

\frac{ - 36 - 8}{3}  = x

\frac{44}{3}  = x

Suppose that circles R and S have a central angle measuring 80°. Additionally, the measure of the sector for circle R is
riadik2000 [5.3K]
The correct answer is B) 9 m.

The measure of the sector of circle R is 32π/9 m.  The measure of the central angle is 80°.  This means that the sector is 80/360 = 2/9 of the circle.  The area of a circle is given by A=πr², so the area of the sector is A=2/9πr².  To verify this, 2/9π(4²) = 2/9π(16) = 32π/9.

Using this same formula for circle S, we will work backward to find the radius:

18π = 2/9πr²

Multiply both sides by 9:
18*9π = 2πr²
162π = 2πr²

Divide both sides by 2π:
162π/2π = 2πr²/2π
81 = r²

Take the square root of both sides:
√81 = √r² 
9 = r

A line has the equation 3x–4y–12=0.<br><br> Is the point (2, −1) on the graph?
zmey [24]

Answer:

The point (2, -1 ) is not on the graph of the line.

Step-by-step explanation:

3x–4y–12=0

3*2 - 4*(-1) - 12= 0

6 + 4 - 12 =0

10 - 12 = 0

- 2 = 0 , false, so the point (2, -1 ) is not on the graph of the line.
