The formula for distance is :
d = √(x₂-x₁)²+(y₂-y₁)²
Let the point (10;10) be (x₂; y₂) , and let the point (4;10) be (x₁;y₁).
So it would look like this -
d = √(10-4)² + (10-10)²
d = √(6)²+ (0)
d = √36
d = 6 units

Answer:
a. 47
b. 87
c. 127
Step-by-step explanation:
Assume a total of 4 exams ( first 3 plus a final)
Let final score be X,
Hence, average score = (85 + 71 + 77 + x) / 4 = (233 + x) / 4
a) to get a C, the average score must be 70
70 = (233 + x) / 4
(233 + x) = 70 (4) = 280
x = 280 - 233 = 47 (Ans)
b) to get a B, the average score must be 80
80 = (233 + x) / 4
(233 + x) = 80 (4) = 320
x = 320 - 233 = 87 (Ans)
c) to get a A, the average score must be 90
90 = (233 + x) / 4
(233 + x) = 90 (4) = 360
x = 360 - 233 = 127 (Ans)
