I just found one outside, hanging on by a string. I brought it in my house to live among my plants. I'm trying to save it's life. I have done this before & it worked for a while. I don't have the heart to let it die slowly in the cold. Does anyone know anything about them?

I made a chart of values, and here's what it looks like:
X 1 2 3 4 5 6 7 8 9 10 11 12
Y 12 22 30 36 40 42 42 40 36 30 22 12

The graph is in the shape of a parabola. I would like the answer, but if you could also, please explain how you got it.

Thank You!

A cyclist competes in a one-lap race around a flat, circular course of radius, r. Starting from rest and speeding up at a constant rate throughout the race, the cyclist covers the entire course in a time (delta)T. The mass of the bicycle (including the rider) is m. What is the magnitude of the net force acting on the bicycle as it crosses the finish line?

Express the net force in terms of r, (delta)t, m, and "pi".

In class we are working on using the radial and tangental and I do not need to solve the problem, just need to write out the net force with the above variables.
thanks!

I am doing a report on squirrel monkeys for school this is a required topic and there isnt very much information online. I know they live in Northern South America but there is no reason why. I would think that they just prefer it there but there is information that shows they avoid parts of Brazil. Anything you know, such as there is more abundant food sources, or there is less predators there would be fine thanks

a compound has been isolated that can have either of two possible formulas:(a)k[fe(C2O4)2)(H2O)2 ]or (b)k3[fe(C2O4)3]. to fine which is correct,you dissolve a weighed sample of the compound in acid and then titratethe oxalate ion(C2O4 -2) that comes from the compound with potassium permanganate,kMnO4.the balanced net ionic equation for the titration
5C2O4-2+2MnO-4+16H+ gives 2Mn+2 +10CO2+8H2O

tyitration of 1.356 g of the compund requires 34.50ml of 0.108 M KMnO4.

(y+10)^2-72=0

so far:
(y^2+20y+100)-72=0
y^2+20y+100-72=0
y^2+20*y+28=0

now, to obtain a real number
to plug in, if there is more than
one solution I am supposed to separate them
with a comma

My husband is taking Lotrel for high blood pressure, which is caused by a tumor on his adrenal gland.

He has a constant feeling of a quick, "racing" heartbeat. Could this be a side effect of the medication?

In a military test, a 575 kg unmanned spy plane is traveling north at an altitude of 2300 m and a speed of 500 m/s. It is intercepted by a 1360 kg rocket traveling east at 775 m/s. If the rocket and the spy plane become enmeshed in a tangled mess, where, relative to the point of impact, do they hit the ground?

_______ km
_______ angle north of east
