Answer:

R ≥ 5

Step-by-step explanation:

$\frac{R}{2}$ ≥ 2.5 To solve, multiply both sides by 2

2 x $\frac{R}{2}$ ≥ 2.5 x 2

R ≥ 5

Write the equation of the line passing through the point (-4 "-7)" and (8 "-17)"

kicyunya [14]

Answer:

$y = -\dfrac{5}{6} x -\dfrac{31}{3}$

In order to find equation:

<u>Find slope</u>:

$\sf slope: \dfrac{y_2 - y_1}{x_2- x_1} = \dfrac{rise}{run}$

$\rightarrow \sf slope: \dfrac{-17-(-7)}{8-(-4)}$

$\rightarrow \sf slope: -\dfrac{5}{6}$

Then find equation using:

y - y1 = m(x -x1) where (x1, y1) are points, m is slope

$\sf \rightarrow y - (-17) = -\dfrac{5}{6} (x - 8)$

$\sf \rightarrow y = -\dfrac{5}{6} x + \dfrac{20}{3} -17$

$\sf \rightarrow y = -\dfrac{5}{6} x -\dfrac{31}{3}$

Need help with this math problem

-BARSIC- [3]

z = 37°

Step-by-step explanation:

The exterior angle theorem says that the sum of two internal angles is equal to the exterior angle

In this case the sum of z and z+4 will be equal to z+41

Writing mathematically

$z + z+ 4 = z + 41\\2z+4 = z + 41\\2z -z = 41 -4\\z = 37$

Hence

z = 37°
