8 0

Answer:

Step-by-step explanation:

Diameter = 20 cm

Radius = r = 20 ÷ 2 = 10 cm

\boxed{\text{Area of circle =$\pi r^{2}$   }}

                      = π *10 * 10

                     = 100π cm²

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)

(x+6) is a factor of f(x). Solve f(x)=0.<br>x3 - 52x – 96​
Mars2501 [29]
<h3>I'll teach you how to solve f(x)=0x63 - 52x – 96​</h3>

----------------------------------------------------------

f(x)=0x^3 - 52x – 96​

Apply rule:

0 * a= 0

0-52x-96

Group like terms:

-52x+0-96

Add/subtract the numbers:

0-96= -96

-52x-96

Your Answer Is -52x-96
