Answer:

40π in²

Step-by-step explanation:

The area (A) of sector ODC is calculated as

A = area of circle × fraction of circle

   = πr² × \frac{72}{360}

   = π × 10² × \frac{1}{5} = \frac{100\pi }{5} = 20π cm²

Sector OAB is congruent to sector ODC, thus

area of shaded regions = 2 × 20π = 40π in²

Y axis is counting by 2's
it started at 2 and went up to 6
Y = 4

X axis is counting by 2'2
starts at one goes to 3
X = 2

Slope is 4/2 because rise over run
4/2 = 2
Slope is simplified to 2.

Write an equation in slope-intercept form for the line that satisfies each set of conditions.
finlep [7]

Answer: Y= 2/3x + 9

Explanation: The equation is in slope-intercept form, y=mx+b. Since it is parallel to the equation, it has the same slope (2/3x) and since b is the x intercept, b is 9.

Elden [556K]

Looks like a pretty regular system, no parallel lines.  In fact the second equation is a vertical line as written; not sure if that's a typo.  Either way,

A 25 kg rock , is raised to the top of a hill 10 m high. What is the PE of the rock ?
nexus9112 [7]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

Potential  \:  \: Energy =(mass) \times (gravity \: acceleration) \times (height) \\

_________________________________

If gravity acceleration is 10 :

PE = 25 \times 10 \times 10

PE = 2500

_________________________________

If gravity acceleration is 9.8 :

PE = 25 \times 9.8 \times 10

PE = 25 \times 98

PE = 2450
