First find the derivative,

\dfrac{d}{dt}\Big(-10\cos(4t)\Big)=40\sin(4t).

Then find the critical point,

40\sin(4t)=0\implies t=40\mathrm{s}.

Hope this helps.

I am a little rusty here :(.

M is directly proportional to r2.when r=2,m=14.Work out the value of r when m =224
balandron [24]
<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷ M = k x r^2

Substitute in the values:

14 = k x 2^2

Divide both sides by 2^2 to find k:

k = 3.5

Substitute the new values in:

224 = 3.5 x r^2

Divide both sides by 3.5 to find r^2

r^2 = 64

Square root it:

r = 8

myrzilka [38]
The term to term rule is to subtract 4

Term 1 = 27
Term 2 = 27 - 4 = 23
Term 3 = 23 - 4 = 19
Term 4 = 19 - 4 = 15
Term 5 = 15 - 4 = 11
Term 6 = 11 - 4 = 9
Term 7 = 9 - 4 = 5
Term 8 = 5 - 4 = 1
Term 9 = 1 - 4 = -3
Term 10 = -3 - 4 = -7
Term 11 = -7 - 4 = -11

The eleventh term = -11
