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

Answer:
26cm
Step-by-step explanation:
Pythagoras' theory
10^2 + 24^2 = c^2
100 + 576 = 676
root of 676 is 26
The equation of a circle with center at (h,k) and radius r is

we are given
center is at (3,2)

solving for y



take the derivitive to find the slope at any point

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

where

that's the equation of the tangent line at (h,k) for arbitrary values of r
do the plots and other stuff yourself
