If an arrow is shot upward on the moon with a velocity of , its height in meters after seconds is given by . (a) Find the average velocity over the given time intervals. Do not round off your answers. t=[1,2],[1,1.5],[1,1.1],[1,1.01],[1,1.001]

thanks a lot and nite nite

ok i found 1 point that's 11.17 rite?

i give up i did as wat u say for both first and second curve but still it doesn't show any intersection point when i go between x=1 and up to x=25 :confused:

huhmm i can find any answers for the intersection. i think i have to leave out this question. do u know any other ways to graph and view the intersection beside do the second trace then press intersection button?

it's still have no intersection point between 10 or 12-13

i can not find the intersection of 400x^5

yeah i got the first problem rite. thanks

and the other problem is compare the functions f(x)=x^5 and g(x)=5^x by graphing both f and g in several viewing rectangles. a) find the x-coordinates of the point intersectionof the two curves accurate to two decimal places. and i did the graphing w/ a result of (1.70,1.70) is that rite...

the exact phrasing was what i posted it on at first.

yes i did every single posible way but it stills said "wrong" or the answer is not accepted.

beside i still have 1 more problem that is really need help will u able to help me please?

yes and the function f(x)=5*1/3^x that's what i had got before but when i put down in the answer and it said "wrong", can u help me ??

yep a=3radical1 rite?

Thanks a lot for ur help. Actually i did the problem 5 times already and i knew C=5 but i can not find a=? and My assignment is about to be due in half an hour. Again thanks for ur help
