The answer is: [A]: He did not apply the distributive property correctly for 4(1 + 3i) .
_____________________________________________
Explanation:
______________________
Note the distributive property of multiplication:
_____________________________
a*(b+c) = ab + ac.
____________________________
As such: 4*(1 + 3i) = (4*1) + (4*3i) = 4 + 12i ;
_____________________________________
Instead, Donte somehow incorrectly calculated:
_____________________________________
4*(1 + 3i) = (4*1) + 3i = 4 + 31; (and did the rest of the problem correctly);
Note: - (8 - 5i) = -8 + 5i (done correctly;
___________________________________
So if Donte did not apply the distributive property correctly for 4*(1+3i)—and incorrect got 4 + 3i (as mentioned above); but did the rest of the problem correctly, he would have got:
_____________________________
4+ 3i - 8 + 5i = -4 + 8i (the incorrect answer as stated in our original problem.

Answer:
892.85 miles for 22 days
Step-by-step explanation:
Answer:
(a)
--- The function
(b)
--- The salary in 5 years
Step-by-step explanation:
Given

Solving (a): Model the function around (1,24100) and (3,36600)
First, we calculate the slope




The function is then calculated as:




Solving (b): Salary in 5 years
Here:

So:



You just simplify the fraction (so, 8/6 which is 4/3)
So your comes 4(square root of 35)/ 3 (square root of 15)
