Answer:

dy/dx = 2/x

Step-by-step explanation:

y = In x^2

Let u = x^2

du/dx = 2x

y = In u

dy/du = 1/u

dy/dx = dy/du × du/dx = 1/u × 2x = 1/x^2 × 2x = 2/x

Use the midpoint formula to estimate the sales of Cars, Inc. in 2009, given the sales in 2008 and 2010. Assume that the sales of

lana [24]

Answer:

<em>The estimated sales were $260 million</em>

Step-by-step explanation:

Assume the endpoints of a segment are (x1,y1) and (x2,y2).

The midpoint (xm,ym) is calculated as follows:

$\displaystyle x_m=\frac{x_1+x_2}{2}$

$\displaystyle y_m=\frac{y_1+y_2}{2}$

The sales ov Cars, Inc. were (2008,240 million) and (2010,280 million). We need to use the midpoint to estimate the sales in 2009:

$\displaystyle x_m=\frac{2008+2010}{2}=2009$

$\displaystyle y_m=\frac{240+280}{2}=260$

The estimated sales were $260 million

How do I find this help please

KIM [24]

Area of the sector = 1/2 * r^2 * theta where theta is the angle subtended by the arc at the center ( in radians)

In this case m < theta = 360 - 235 = 125 degrees or 2.182 radians

So, the area of shaded area = 1/2 * 20^2 * 2.182 = 436.4 in^2

BabaBlast [244]

Hello.

The answer to your question is =
12, 3 x 4 and 6 x 2.
24, 3 x 8 and 6 x 4.
36, 3 x 12 and 6 x 6.
48, 3 x 16 and 6 x 8.

So it's pretty much everything except for 32.
Have a great day!
