177 miles/3 hour x (5280 ft/1 mile) x (1 hour/3600 seconds)=934560/10800=86.533 ft/sec

86 ft/sec

I need help solving this problem. <img src="https://tex.z-dn.net/?f=4x%20cos%20%5E%7B-1%7D%20%282x%2B4%29-%20%5Csqrt%7B3-3%20x%5

Given:
$f(x)=4xcos^{-1}(2x+4)-\sqrt{3-3x^2}$

Using
$\frac{d}{dx}cos^{-1}(x)=-\frac{1}{\sqrt{1-x^2}}$
we derive
$\frac{d}{dx}4xcos^{-1}(2x+4)$
$=4cos^{-1}(2x+4)-\frac{8x}{\sqrt{1-(2x+4)^2}}$

Similarly, using
$\frac{d}{dx}\sqrt{x}=\frac{1}{2\sqrt{x}}$
we derive
$\frac{d}{dx}(-\sqrt{3-3x^2})$
$=\frac{3x}{\sqrt{3-3x^2}}$

Therefore, the derivative is
$f'(x)=\frac{d}{dx}(4xcos^{-1}(2x+4)-\sqrt{3-3x^2})$
$=4cos^{-1}(2x+4)-\frac{8x}{\sqrt{1-(2x+4)^2}}+\frac{3x}{\sqrt{3-3x^2}}$

G is the centroid of triangle ABC. If BF=12, what is BG?<br> BG=?

lutik1710 [3]

Answer:

BG = 8

EXPLANTAION :

we know that centroid of a triangle divides the median into ratio of 2 : 1 so,

BG : GF = 2 : 1

now, let's take BG as 2x and GF as x

and here, BG + GF = BF

So,

=》2x + x = 12

( because, BF = 12 )

=》3x = 12

=》x = 12 ÷ 3

=》x = 4

hence, x = 4

from here,

=》BG = 2x

=》BG = 2 × 4 = 8
