Answer:
- incorrectly; used 1 in the division instead of -1
- incorrectly; evaluated higher powers of -1 incorrectly
Step-by-step explanation:
The result each should have obtained is ...
a +10 = 17
a = 7
Braulio's mistake was in using 1 as his divisor instead of -1. His bottom row should have been 1, 4, a-4, 1-a, a +10.
Zahra's mistake was improperly evaluating higher powers of -1. Her evaluation should have been 1 -5 +a +3 +11 = a +10.
Answer: Prism
Step-by-step explanation:
Answer:
a) Magnitude = 10.72
b) = 0.32 and 0.400
c) Drug B is closest to having the desired effect.
Step-by-step explanation:
The knowledge of vector projection and dot product is applied as shown in the step by step explanation from the attached file.
For better representation, I think the function is written as:
B(x) = 40.00 - 0.08x
This is much more comprehensive. The variable x represents the number of prints. So, if x=40 prints, we replace this to the x in the equation to find the balance B.
B = 40 - 0.08(40)
<em>B = $36.8</em>
