What happened to your equal sign Mathematician?

The question does not make sense .....

So does this mean that the answer cannot be determined without more information?

I stand corrected.

Thanks Alan :))

Hmm!

.

Sorry I just realized that you wnated it in Hexidecimal.  (It is answered on the middle row of the table)

\(11001110101110111_2= 19D77_{16}\)

If i have Q=(8/15) Ctan(Φ/2) if i move tan to the other side of the equal sign what does it become?

I'm confused.

why do you have a Q and a Phi   and what is Ctan?  I mean why is there a C in front of the tan?

Use the [2nd] in the top left hand corner   :)

how do u convert binary to hex by splitting it into nibbles? stuck in my computing lesson

take this binary number

11001110101110111

I am going to split it into groups of 4 from the right

1   1001   1101    0111    0111

Add this altogether and you get

65536+36864+3328+112+7 = 105847

so

\(11001110101110111_2=105847_{10}\)

This is a really unusual question.

Let r(x)=F(g(h))),

where h(1)=2,        g(2)=5,        h'(1)=4,          g'(2)=4,          and      f'(5)=6.     [I will assume tht f'(5) is really F'(5)]

Find r'(1).

\(r(x)=F(g(h))\\ r(x)=F(g(h(x)))\\ r'(x)=F'(g(h(x)))\\ r'(1)=F'(g(h(1)))\\ r'(1)=F'(g(2))\\ r'(1)=F'(5)\\ r'(1)=6\\ \)

The velocity is given by v = -w*A*sin(wt+sigma)

The velocity is zero when wt + sigma = n*pi     or:   t = (n*pi - sigma)/w

.

Just type abs(x).  For example:  abs(-5) results in 5

.

If F(x) =7x^2-x^3, find f'(1) and use it to find an equation of the tangent line to the curve y=7x^2-x^3 at the point (1,6)

ind an equation of the tangent line to the graph of y=g(x) at x=5 if g(5)=-2 and g'(5)=4. Answer should be in terms of y and x.

If you click the youtube logo on the bottom right, it should take you to the same video but on youtube, so it might be the one you found.

Is this the similar video you found?

because math.

I think you could solve this using the Gaussian elimination, but I haven't fully understood how it works because I just started learning about matrices.

so heres how you do it:

do step one, then step two, and then continue until you have done all of the steps!!!

Interesting, I'd probably have to learn a bit more about what a matrix is to understand though

This is the answer:

Interested to see how it is worked out. I have only briefly (VERY briefly) learned about matrices back in Algebra II and I've never heard of them since.
