Given that S is the centroid of triangle MNO, find SQ.

DochEvi [55]

Answer:

First, we need to calculate for x. Since,

MP = PN

Thus,

3x-4 = x+4

2x = 8

x = 4

Next, we calculate for MS

MS = 2x + 2 = 10

Since, MS = 2SQ

10 = 2SQ

Then,

SQ = 5 units

Therefore, the correct answer is B.

Given the arc length of a circle is 127π centimeters and the subtended angle is 60˚. Find the Circumference of the circle.

Mumz [18]

The circumference of the circle is 762π cm.

<h3>What is length of arc of a circle?</h3>

The length of arc a circle can is determined with the radius and central angle of the arc.

The radius of the circle is calculated as follows;

$L = \pi r \times \frac{ \theta }{180} \\\\
\pi r \theta = 180 L\\\\
\pi r = \frac{180 L}{\theta}$

The circumference of the circle is calculated as follows;

$C = 2\pi r\\\\
C = 2(\pi r)\\\\
C = 2(\frac{180 \ L}{\theta } )\\\\
C = 2(\frac{180 \times 127\pi}{60 } )\\\\
C = 762 \pi \ cm$

Write an equation of the line passing through (-2,4) and (3,5). Give the answer in standard form.The equation of the line in sta

Alecsey [184]

Start finding the slope of the line

$\begin{gathered} m=\frac{y_2-y_1}{x_2-x_1} \\ \text{then,} \\ m=\frac{5-4}{3-(-2)} \\ k=\frac{1}{5} \end{gathered}$

using one of the points find the intercept and the standard form

$\begin{gathered} (-2,4) \\ 4=\frac{1}{5}(-2)+b \\ b=4+\frac{2}{5} \\ b=4.4 \end{gathered}$

the equation of the line is

$y=\frac{1}{5}x+4.4$
