Simplify. (6+7i)(3−4i) Enter your answer, in standard form, in the box.
xxTIMURxx [149]

Answer: 46-3i

Step-by-step explanation: Use the FOIL method, (a+b)(c+d)=ac+ad+bc+bd. Collect like terms then simplify.

(6+7i)(3−4i)

18−24i+21i+28

(18+28)+(−24i+21i)

46-3i

- Hope this helps, have a blessed and wonderful day! :-)

Matlab the equation of a circle with its center at x=3 and y=2 is given by , where r is the radius of the circle. first derive t
Blizzard [7]
The equation of a circle with center at (h,k) and radius r is
(x-h)^2+(y-k)^2=r^2
we are given
center is at (3,2)
(x-3)^2+(y-2)^2=r^2
solving for y
(y-2)^2=-1(x-3)^2+r^2
y-2=\sqrt{-1(x-3)^2+r^2}
y=2+\sqrt{-1(x-3)^2+r^2}
take the derivitive to find the slope at any point
\frac{dy}{dx}=((-1)(x-3)^2+r^2))(-x+3)


we can use point slope form
for apoint (h,k) and slope m, the equation is
y-k=m(x-h)
not sure if you want in terms of what
I'll just say for a point (h,k)
so we get
y-k=((-1)(x-3)^2+r^2))(-x+3)(x-h)
where k=2+\sqrt{-1(h-3)^2+r^2}
that's the equation of the tangent line at (h,k) for arbitrary values of r

do the plots and other stuff yourself
