Answer:

Smaller x value = -1 and y = -2.

Larger x value = 1 and y = 2.

Step-by-Step explanation:

x^2 + y^2 = 5

y = 2x

Substitute y = 2x into the first equation:

x^2 + (2x)^2 = 5

x^2 + 4x^2 = 5

5x^2 = 5

x^2 = 1

x = ±1

So y = 2 * ±1 = ±2

Area enclosed by one loop of r=3sin(5theta)

MA_775_DIABLO [31]

Hello,
$Area= \int\limits^a_b {\rho^2} \, d\theta$

$\frac{1}{2} \int\limits^{\frac{\pi}{5}} _0 {(3\ sin(5\theta))^2} \, d\theta\\\\
=\frac{9}{4} \int\limits^{\frac{\pi}{5}} _0 {(1-cos(10\theta))} \, d\theta\\\\
=\frac{9}{4} [\theta-\frac{sin(10\theta)}{10}]^\frac{\pi}{5}} _0 \\\\
=\frac{9\pi}{20}$

The slope of a line is 5, and you know it goes through the point (6, 2). Another point on the line goes through the y-coordinate

grigory [225]

Y = mx + b
slope(m) = 5
(6,2)...x = 6 and y = 2
sub and find b, the y int
2 = 5(6) + b
2 = 30 + b
2 - 30 = b
-28 = b
so the equation for this line is : y = 5x - 28

y = 5x - 28.......when y = -3
-3 = 5x - 28
-3 + 28 = 5x
25 = 5x
25/5 = x
5 = x <==== ur x coordinate
