1) Solve: 3y/2 = 7+y/4

2) Solve: 1/2x + 1/x = 3/8

3) Solve: x/5 = x+4/9

4) Solve: 3/x+4 - 1/x = 1/x

5) Solve 6/x+2 = 2/x-4

1) Use calculus to determine an approximate value for 2 / cube root of 7.8, leaving your answer correct to 4 decimal places.

2) Differentiate sqrt (x^2 + 9) with respect to x and hence find the exact value of the intergration of (3x) / sqrt (2x^2 + 18) with limits 0 to 4.

*Please show all essential workings. Thanks (:

In December, the (British) government proposed a ban on creating the hybrid embryos because of public unease at the idea, but it later bowed to protests by scientists who feared Britain could lose its leading role in stem cell research.

Opponents say mixing even a tiny amount of human genetic material with that of an animal is unnatural and wrong.

imagine we have something that looks like a ring
if we try to fill nside of the ring with lets very soft clay if we start from inside, clock wise or anti clock wise doesnt matter imagine putting some clay on your finger and rubbing it inside the ring if we do this layers after layers i believe we will never be able to fill the whole ring with clay beacuse we will always have a hole inside the ring.and becuse of the space
could this be true?can you explain a bit

Calculate H for the following reaction,

CaO(s) + CO2(g) --> CaCO3(s)

given the thermochemical equations below.

2 Ca(s) + O2(g) --> 2 CaO(s) H = -1270.2 kJ
C(s) + O2(g) --> CO2(g) H = -393.5 kJ
2 Ca(s) + 2 C(s) + 3 O2(g) -->2 CaCO3(s) H = -2413.8 kJ

a. -4077.3 kJ
b. -750.1 kJ
c. -178.3 kJ
d. +350.2 kJ
e. +2870.6 kJ



How do you solve??
