Y = -3x + 22

plug in the given point and the slope into point slope form:
y-7 = -3 (x-5)

solve for y to get slope intercept form
y-7 = -3x + 15
y = -3x + 22

Answer:

y=-3x+7

Step-by-step explanation:

The slope form is y=mx+b

7 replaces B since the points intercept at positive 7. The slope is already given to you so that ur equations

Use the method of reduction of order to find a second solution to t^2y' + 3ty' – 3y = 0, t> 0 Given yı(t) = t y2(t) = Preview
Anestetic [448]

Let y_2(t)=tv(t). Then

{y_2}'=tv'+v

{y_2}''=tv''+2v'

and substituting these into the ODE gives

t^2(tv''+2v')+3t(tv'+v)-3tv=0

t^3v''+5t^2v'=0

tv''+5v'=0

Let u(t)=v'(t), so that u'(t)=v''(t). Then the ODE is linear in u, with

tu'+5u=0

Multiply both sides by t^4, so that the left side can be condensed as the derivative of a product:

t^5u'+5t^4u=(t^5u)'=0

Integrating both sides and solving for u(t) gives

t^5u=C\implies u=Ct^{-5}

Integrate again to solve for v(t):

v=C_1t^{-6}+C_2

and finally, solve for y_2(t) by multiplying both sides by t:

tv=y_2=C_1t^{-5}+C_2t

y_1(t)=t already accounts for the t term in this solution, so the other independent solution is y_2(t)=t^{-5}.

What is the volume of this container
Schach [20]
First fine the volume of ur big box:

10x10x15
=1500

Then ur small one:

4x4x2
=32

Lastly, subtract the small one from the big one

1500-32
=1468

Ur answer is 1468in^3
