thank you damon

but doesn't the litres in the mol/L have to be converted to mL?

When I did the equation you gave me I got 483mL but that wasn't the answer.

Yes but the answer was incorrect

can you please show me the proper way to do it?

Thank you for all your help it was much appreciated :D

Alright thanks a lot :D

Hey thanks a lot but how did you know to put 8/(24)?

thanks a lot for your help!

so then would the answer be 2.07?

ok thanks a lot for your help :D

Thanks for your help :D

by the way did you multiply the equation by 10 to get rid of the decimal to get a whole number?

alright thanks :D

I have one last question. How did you know a=1?

like sorry for the sequence 1, 4, 16 how did you get 1?

why didn't you use this equation: 765=3(2)^n-1

wait I understand thanks for your help :D

How do you get the values?

I got 1.7*10^4L but not sure if I was correct or not

I figured it out thanks for your help :D

but the answer says that it's a max of 65/8 at x=5/4

but that wasn't the correct answer

so can you show me the correct way to do it?

wait nvm thanks for your help :D

ok thanks a lot for your help :D

Ok thanks a lot for your help steve :D

sorry it should be corrected to t

Determine the intensity of radiation andits rate of change on Earth, which is 1 AUfrom the Sun.

The answer says the ROC is -2737.8

I don't completely understand

because when I do that I get a different answer than there is

This question requires you to enter the given values into the equation, and add y1 and y2 together. y1 = 2.90 cos (3.80(1.50) - 1.50(1.40)) y2 = 3.90 sin (4.80(1.50) - 2.10(1.40)) y1 + y2 = -6.12 cm

I would say C then?

Could someone explain it entirely to me?

:') ayo thas my name..also thank you so much!
