Solve these system of linear equations:

frutty [35]

1.solve for y
2x+4y=12
 -2x -2x
4y=12-2x
4 4
y=3-1/2x

step2 plug in y and solve for x
2x+8y=24
2x+8(3-1/2x)= 24
2x+24-4x=24
-2x=0
-2 -2
x=0
last step plug in x and solve for y

y=3-1/2x(0)
y=3

If L=√(x^2+y^2), dx/dt =-4, dy/dt=3, find dL/dt when x=4 and y=3

yulyashka [42]

Hello,

$L=\sqrt{x^2+y^2} \\\\\dfrac{dx}{dt}=-4\\\\\dfrac{dy}{dt}=3\\\\x=4, y=3\\\\\dfrac{\partial L} {\partial x} =\dfrac{x}{\sqrt{x^2+y^2}} \\\\\dfrac{\partial L} {\partial y} =\dfrac{y}{\sqrt{x^2+y^2}} \\\\\dfrac{dL}{dt} =\dfrac{\partial L} {\partial x}*\dfrac{dx}{dt}+\dfrac{\partial L} {\partial y}*\dfrac{dy}{dt}\\\\=-4*\frac{-4}{\sqrt{4^2+3^2}} +3*\frac{3}{\sqrt{4^2+3^2}}\\\\=\dfrac{16}{5} +\dfrac{9}{5} \\\\=5\\$

A paper air plane looking polygon with sides of 5 5 and 8 what is the area

VARVARA [1.3K]

If it has 3 sides then it's a triangle.
Using the formula $A= \sqrt{s(s-a)(s-b)(s-c)}$
where $s= \frac{a+b+c}{2}$
and a=5 b=5 c=8

∴ $s= \frac{5+5+8}{2} =9$
$area= \sqrt{9(9-5)(9-5)(9-8)}$
$area= \sqrt{144} = 12units^{2}$
