a) how tall will it be after 6 months?
i keep getting like 388 for part a but when you do the limiting sum to see its final height i get 75 can any help pleaseee
hi, how would you integrate:
e^(3x) + 1/e^(2x)
e to the power of 3x then plus 1, all divided by e to the power of 2x
i separated the terms so it was e^(3x)/e^(2x) + 1/e^(2x) but im not sure how to go about integrating e^(3x)/e^(2x)
thankyouu and can you please show working
for the first question i dont really understand why the +1 isn't a power any more, in the question i didn't really write this clearly but its y=4^(x+1) if that changes anything?
and with the second question i had the first bit you wrote its just after that im struggling with the differentation...
thankyouu I have some more
1. Find the equation of the tangent to the curve y=4^x+1 at the point (0,4)
2. Find the equation of the normal to the curve y=log3x at the point where x=3
3. find the exact volume of the solid formed when the curve y=logex is rotated about the y axis from y=1 to y=3
1. The half life of radium is 1600 years.
a) find the percentage of the radium that will be decyaed after 500 years
b) find the number of years that it will take for 75% of the radium to decay.
For a i got 80.5% as an answer but for the correct answer you need to minus this from 100% and i...
Is a concave down graph shaped like an unhappy face and concave up shaped like a happy face? Because in the text book it says y">0 the curve is concave up, so the graph should look like a happy face before x=1 and then look like an unhappy face after x=1? because when i drew that it was he same...
