Answer:
2-9i
Step-by-step explanation:
(3-4i)(1+5i)-(2-1)
Expand the algebra expression, and we have
3(1+5i)-4i(1+5i)-(1)
3+15i-4i-20i-1
Collect like terms
3-1+15i-4i-20i
2+11i-20i
2-9i
Please note that algebra expressions does not have the sign of equality.
the answer is B because you go from
P to Q
then Q to R
and ultimately
P to R
Answer:
The linear approximation is ;
F(x,y) = x -5y - 1
Step-by-step explanation:
Here, we want to find the linear approximation of the given function at the indicated point.
We start by substituting the values then after wards finding the partial derivative with respect to x and then to y.
We finish by adding up these values after substituting the values of x and y into the differentiated partial equation. We then add up our results.
