1. ### Would k(a-b) x (a x c) -a +( b x c) be a scaler, vector or meaningless? (these are all vectors besides k)?

...two vectors. Does it make sense? Yes, it's another vector. k(a-b) x (a x c) is the cross product of two vectors. Does it make sense? ...

2. ### CMO Problem: Just for fun :-)?

Using the binomial theorem (sqrt(2)-1)^k = C sqrt(2) - D where C and D ...1) = Csqrt(2) - D then (sqrt(2)-1)^k = -(C+D)sqrt(2) + (2C+D) If...

3. ### Consider the points A(7,k), B(11,4), and C(13,1 - 3k)?

They lie on a straight line if the gradient of AB equals the gradient of BC So (4-k)/4 = (1-3k-4)/2 Maybe you can take it from there !

4. ### Simplify equation in the form of af(k(x-d))+c?

You didn't kill the f off when you put the squared sign in and also there's no reason for the minus sign of x-1 to randomly become a plus... Thus y=7(-1/6(x-1))^2+1 is what you're after. So y=7(1/36(x-1)(x-1)) and tbh I wouldn't much bother with multiplying that out '...

5. ### prove that no real value of k exists for the equation x^2-kx+2k-10=0 has equal roots.(has onlyone value for x)?

QE : 1x² + (-k)x + (2k-10) = 0 ∴ a = 1, b = -k, c = 2k - 10 .......... (1) For equal roots, discriminant Δ = b²...

6. ### ab^k(x-d) +c 11u math help please!!?

Yes it is the same . Just like y = mx+b is the same as y = b+mx We just usually write the vertical shift last, since it's the last computation. Hoping this helps!

7. ### translation of a function in the for af[k(x-d)]+c?

Those two interpretations are equivalent, and they are both correct. Let me explain something with a simpler example. Begin with the graph of this equation: y = f(x) Transform it to this: y = -2f(x) This typically is...

10. ### Does the "k" and "c" in these quadratics equal the y intercept? y= a(x-p)^2 +q and y=ax^2 +bx =+c

In the first one you need to evaluate the equation for x = 0 to find the y-intercept. y = a(0-p)^2 + q y = ap^2 + q this will be the y -intercept You can do the same in the second, but it will be "c", yes.
