What is 16 divided by X^2 equals 8 divided by X + 6?

zaharov [31]

Solve: $\frac{16}{x^{2}} = \frac{8}{x + 6}$

$\frac{16}{x^{2}} = \frac{8}{x + 6}$

$\text{Cross multiply: } 16(x + 6) = 8x^{2}$
$\text{Simplify: } 2(x + 6) = x^{2}$
$\text{Expand: } 2x + 12 = x^{2}$

$\text{Solve for x: } x^{2} - 2x - 12 = 0$

$\text{Use the quadratic equation: } x = \frac{-b \pm \sqrt{b^{2} - 4ac}}{2a}$
$x = \frac{2 \pm \sqrt{4 + 48}}{2}$
$x = \frac{2 \pm \sqrt{52}}{2}$
$x = \frac{2 \pm \sqrt{13 \cdot 4}}{2}$

$x = \frac{2 \pm 2\sqrt{13}}{2}$
$\therefore x = 1 \pm \sqrt{13}$

Complete the equation of the line through (-6,5)(−6,5)left parenthesis, minus, 6, comma, 5, right parenthesis and (-3,-3)(−3,−3)

sladkih [1.3K]

Answer:

The equation of the line passing through the given points is:

$y=-\frac{8}{3}x-11$

Step-by-step explanation:

Given:

The two points are: $(x_1,y_1)=(-6,5)\textrm{ and }(x_2,y_2)=(-3,-3)$

The equation of a line when two points are given is:

$y-y_1=\left (\frac{y_2-y_1}{x_2-x_1} \right )(x-x_1)$

Plug in all the values and simplify.

$y-5=\left (\frac{-3-5}{-3-(-6)} \right )(x-(-6))\\y-5=\left (\frac{-8}{-3+6} \right )(x+6)\\y-5=\left (\frac{-8}{3} \right )(x+6)\\y-5=\frac{-8}{3}x-16\\y=\frac{-8}{3}x-16+5\\\\y=-\frac{8}{3}x-11$

Therefore, the equation of the line passing through the above points is

$y=-\frac{8}{3}x-11$

The height of the carton of oatmoatmeal is 9 inches.

Step-by-step explanation:

Radius = 4 inches

Area of cardboard used = 276 square inches

Required surface area = π(r x r) + 2πrh

276 = π(4 x 4) + 2π(4 x h)

276 = 16π + 8π(h)

276 = 50.24 + 25.12(h)

276 - 50.24 = 25.12(h)

225.76 = 25.12(h)

(225.76) /(25.12) = h

h = 9 inches

The height of the carton of oatmoatmeal is 9 inches.
