KM - KL = LM
3x + 1.5 - (x + 0.5) = 3x - 2
3x + 1.5 - x - 0.5 = 3x - 2
2x + 1 = 3x - 2
1 + 2 = 3x - 2x
3 = x

so KM = 3(3) + 1.5 = 9 + 1.5 = 10.5
KL = x + 0.5 = 3 + 0.5 = 3.5
LM = 3x - 2 = 3(3) - 2 = 9 - 2 = 7 <===

First you have to find the measurement of the entire line,which will be equal x, than plug in in the equation between L and M

Find dy/dx by differentiating implicitly <br> x^2y+3xy^3-x=3

AleksandrR [38]

$\dfrac{\mathrm d}{\mathrm dx}\left[x^2y+3xy^3-x\right]=\dfrac{\mathrm d}{\mathrm dx}[3]$
$2xy+x^2\dfrac{\mathrm dy}{\mathrm dx}+3y^3+9xy^2\dfrac{\mathrm dy}{\mathrm dx}-1=0$
$(x^2+9xy^2)\dfrac{\mathrm dy}{\mathrm dx}=1-2xy-3y^3$
$\dfrac{\mathrm dy}{\mathrm dx}=\dfrac{1-2xy-3y^3}{x^2+9xy^2}$

A cylinder has a surface area of 1850 square meters and a radius of 9 meters. Estimate the volume of the cylinder to the nearest

Trava [24]

In order to find the volume you need the height.

Surface area = π r² + base x height or width x length
1850 = 3.14 × 9² + radius × 2 x π x height
1850 = 254.34 + 9 × 2 × 3.14 × height
1850 = 310.86 × height

To find the height you have to divide the surface area by the part I bolded

Height = 1850 ÷ 310.56
Height ≈ 6

Volume of a cylinder = πr²×height
= 3.14 × 9 × 9 × 6
Volume =1526.04

Nearest whole number would be 1526
