Review the graph. On a coordinate plane, a circle has center (0, 0) and radius 3. A parabola opens to the left and goes through (7, 3), has vertex (2, 0) and goes through (7, negative 3). Everything inside of the parabola and outside of the circle that is inside of the parabola is shaded.

please help on edgunity .Which system of inequalities has the solution set shown in the graph?

x2 + y2 > 9 and y < –x2 + 2
x2 + y2 < 9 and y < –x2 + 2
x2 + y2 > 9 and x < –y2 + 2
x2 + y2 < 9 and x < –y2 + 2

answer: 43/157

this is the answer and if you try to prove me wrong your a meanie

step-by-step explanation:

cause i just did this and got the answer

you're welcome

the value of x is 9 ⇒ answer b

step-by-step explanation:

* we can solve this problem using cosine and sine rule

- in δ abc

∵ ab = 36 , bc = 28 , ac = 16

- lets find the measure of angle b using the cosine rule

∵ cos b = [ab² + bc² - ac²]/2(ab)(bc)

∴ cos b = [36² + 28² - 16²]/2(36)(28)

∴ cos b = 19/21

∴ m∠b = cos^-1(19/21) ≅ 25°

- lets find the measure of angle a using the sine rule

∵ sina/bc = sinb/ac = sinc/ab

∴ sina/28 = sin25°/16 ⇒ by using cross multiplication

∴ sina = 28 × sin25°/16

∴ sina = 0.7396

∴ m∠a = sin^-1(0.7396) ≅ 48°

- from the figure m∠abd = m∠dbc

∵ m∠abc = 25°

∴ m∠abd = 25°/2 = 12.5°

- in δabd

∵ m∠a = 48° , m∠abd = 12.5°

∵ the sum of the measures of the interior angles of any δ is 180°

∴ m∠adb = 180° - (48° + 12.5°) = 119.5°

∵ ab = 36

∵ ad = x

- use the sine rule to find x

∵ sin∠adb/ab = sin∠abd/x

∴ sin119.5°/36 = sin12.5°/x ⇒ by using cross multiplication

∴ x = 36 × sin12.5°/sin119.5° = 8.95 ≅ 9

* the value of x is 9
