AI Thread Summary
To find the intersections of the graphs defined by the equations x^2+y^2=41 and x+2y=6, rearrange the second equation to x=6-2y and substitute it into the first equation. This will lead to a quadratic equation that can be solved for y. For the piecewise function given, the equivalent function is g(x)=|x-3|, as it matches the conditions of the piecewise definition. Reviewing similar problems and practicing will enhance understanding and preparation for the test. Good luck on the test tomorrow!

quiky question before my test tommorow morning!

i can't believe i duno where to find out how to do this:

1) find intersections of the graphs:
x^2+y^2=41
x+2y=6

and

2)which of the following function is equivalent to the following piece function.

x-3, if x>=3
f(x)={
3-x, if x<3

a) g(x)=|x-3| b) g(x)=|x+3| c) g(x)=-|x-3| d)-|x+3| e) none of these

this is off like a study guide checklist for the test.

Rearrange x + 2y = 6 to get x = 6 - 2y. Then plug this into x2 + y2 = 41. You get:

(6 - 2y)2 + y2 - 41 = 0
 


Hi there,

I understand that you have a quick question before your test tomorrow morning. It sounds like you are struggling with some math problems. I would suggest reviewing your notes and practicing similar problems to prepare for your test.

For the first question, you can find the intersection of the two graphs by solving the system of equations. You can do this by substitution or elimination method. I would suggest looking at some examples and practicing similar problems to understand the concept better.

For the second question, the equivalent function is g(x)=|x-3|, option a). This is because the piecewise function given is equal to the absolute value of x-3, which is represented by the function g(x).

I hope this helps and good luck on your test tomorrow! Remember to stay calm and confident, and trust in your preparation. You got this!
 
Thread 'Variable mass system : water sprayed into a moving container'
Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
