The equation of the tangent to the curve x^2 = 4y at the point on the curve where x=-2 is?

aleksandrvk [35]

$x^2 = 4y \Rightarrow y= \frac{x^2}{4}$
$\frac{dy}{dx} = \frac{2x}{4} = \frac{x}{2}$

(x = -2) $\frac{dy}{dx} = \frac{x}{2} = \frac{-2}{2} = -1$
(x = -2) $y= \frac{x^2}{4}= \frac{(-2)^2}{4} = 1$

$y-y_1=m(x-x_1)$
$y-1 = -1(x--2)
$
$y-1 = -1(x+2)$
$y-1 = -x-2$
$y=-x-1 = -(x+1)$

A rectangular hallway rug has a width of 9 feet, and the diagonal measures 41 feet. What is the rug's length?

slega [8]

Answer:

Rug's length is equal to $40$ feet.

Step-by-step explanation:

Width of a rectangular hallway rug $(w)=9$ feet

Diagonal of a rectangular hallway rug $(d)=41$ feet

The relation between width $(w)$ , length $(l)$ and diagonal $(d)$ is given as follows:

$l^2+w^2=d^2$

$l^2+9^2=41^2\\l^2+81=1681\\l^2=1600$

$l=\sqrt{1600}$

$l=40$ feet

So, rug's length is equal to $40$ feet.
