The magnitude of -1-5i is √26.
<h3>What is the magnitude of -1-5i ?</h3>
Given the complex expression; -1 - 5i
To find the magnitude, we use the formula;
| a+bi | = √[ a² + b² ]
| a+bi | = √[ a² + b² ]
| -1-5i | = √[ (-1)² + (-5)² ]
| -1-5i | = √[ 1 + 25 ]
| -1-5i | = √26
Therefore, the magnitude of -1-5i is √26.

19y-9. you distribute -3 into (-4y +3) to get 12y -9 and then you combine like terms so 12y +7y to get 19y and you still have the -9 so the simplest form would be 19y-9
Answer:$11.3 per cooler
Step-by-step explanation:
Answer:
the tree is 8.8 m tall
I can't draw it but it will be two similar acute triangles. The one that represents the man will have a 2m height and a 5m base. The one that represents the tree will have an 8.8m height and a 22 m base.
Step-by-step explanation:
it's a proportional relationship
5/22=2/height
5(height)=2(22)
5(height)=44
divide both sides by 5
5(height)/5=44/5
height=8.8 m
