Answer:
A) 5
Step-by-step explanation:
distance = √(distance between x coordinates² + distance between y coordinates²)
the horizontal distance between the two points is 4
the vertical distance between the two points is 3
to prove this, if you started at Q and went 4 points right and then 3 points up, you would get to P
distance = √(4²+3²) = √25 = 5
C. c^2=a^2+b^2-2abcos(90°)
This is the law of cosine.
The answer 323.4 is pound.
First 25% and 8% together which is 33%.Then find out 33% of 980.33/100×980=323.4 pound.
So he saved 323.4 pound.
