hello, i need help with this question: Find the greatest term in (5-4x)^12, if x = 2/3 Books answer: 12C4 (5^8)(8^4)(3^-4) My answer: 12C5 (5^7)(-8^5)(3^-5)

hi im having trouble answering this question: "suggest a reason why the levels of ultraviolet were higher on land than in the ocean." Thanks in advance

hi im having trouble with this question, i need help. A point moves with SHM; if when at distances of 3 and 4cm from the centre of its path, its velocities are 8 and 6cm/s respectively, find its period and its acceleration when at its greatest distance from the centre. thanks in advance<!--...

Bit confused with shm...how do you do this question? A particle moving with SHM starts from rest at a distance of 8m from the centre of oscillation. If the period is 4 seconds, find the initial acceleration.

hi, how do you this ? A body is prjected from a point 80m above the ground with a velocity of 20 m/s at an angle of 60 degrees above the horizontal. Assuming the ground horizontal, find when and where it will strike the ground thanks in advance

Hi how do you do this question? An oven has been heated to a constant temperature of 250*c. An object with a temperature of 10*c is placed in the oven and after 15minutes its temperature is measured as 70*c What will be the temperature of the object after 30minutes? thanks in advance

Hi can someone check the answer for me? i got 5488kg/m^2 but the answer says 8488kg/m^2 1. Air pressure at an altitude of a metres is given in kilograms per square metre by the formula p = p0 e^ka, where k = -0.00012. If the pressure at the earth's surface is 10000kg/m^2, what is the...

1. A vessel is of such a shape that when the depth of water is x cm the volume is V cm^3, where V = 30x+x^3. Water is pured into the empty vessel at the rate of 25cm^3/s. At what rate is the level of the water rising when the depth is 5cm? Thanks in Advance

Hi can someone work this question out for me? i got the answer x = 48.5 1. A particle moves along the x-axis with an acceleration given by a=6t+3. When t=0, x=5 and the velocity of the partcle is 1unit per second. Find the position of the particle after 3 seconds. Thanks

Calculate the area of the region bounded by: y=1/x^2 + 2 y= -2x+5 x = 4 Answers were not given Thanks in advance.

Hi, i was wondering...Will the final HSC standard english exam contain anything from "Experiences through language" topic? Thanks

Solve for x. Log(base a) 16x = 3log(base a) x Thanks in advance ------------------------------------------- edit Is x =0 and x = 4 and x = -4? I don't have the real answer for this question

Hi, I forgot how you do these type of questions again. Find the smallest term of the sequence 400, 200, 100,..... which is greater than 3 Thanks in advance!
