A curve has the equation x^2+2y^2=3x, by differentiating implicitly find dy/dy in terms of x and y.

We shall differentiate each term in the equation with respect to x. dy/dx (x 2 ) = 2x dy/dx (2y 2 ) = 4y dy/dx dy/dx (3x) = 3 So we now have the equation 2x + 4y dy/dx =3 We now have to rearrange to get in t...

Expand (2x-4)(x+3)

We are going to use the F.O.I.L Method for this expansion, FIRST 2x*x = 2x 2 OUTSIDE 2x*3 = 6x INSIDE -4x*x = -4x LAST -4*3 = -12 Now to add up all the terms we have found 2x 2 +6x-4x+12 = 2x 2 +2x+12

Q = P / (R (4-t)), P=36, R= 3, t=-2

Substitute in each letter for the appropriate number that it equals. Q = 36 / (3 x (4--2)) Q = 36 / (3x(4+2)) Q = 36 / (3x6) Q = 36 /18 Q = 2

An ice cream cone with a base 4.5 cm in diameter and whose height is 10 cm is filled with ice cream. What is the volume of ice cream to 3 d.p.? If the density of ice cream is 1095 kg/m^3, what is the mass of ice cream in 5 cones to 3 s.f.?

Volume of cone= 1/3 Pi h r^2 r=2.25 V=1/3 Pi 10 2.25^2=53.01 cm^3=5.301x10&-5 m^3 Mass=density*volume Mass=(5.301x10^-5) 1095= 0.05805 kg Mass of 5= 0.05805 5=0.290 kg
