Answer:b=5
Step-by-step explanation:the formular for pythagoras theory is
C^2=a^2+b^2
13^2=12^2+b^2
169=144+b^2
Collect like terms
169-144=b^2
b^2=25
Take the the square root of both sides
b=square root of 25
b=5
Equation of the parabola: y = ax^2 + bx + c. Find a, b, and c.
x of axis of symmetry:
x
=
−
b
2
a
=
3
-> b = -6a
Writing that the graph passing at point (1, 0) and point (4, -3):
(1) 0 = a + b + c -> c = - a - b = - a + 6a = 5a
(2) -3 = 16a + 4b + c --> -3 = 16a - 24a + 5a = -3a --> a = 1
b = -6a = -6; and c = 5a = 5
y

5
Check with x = 1: -> y = 1 - 6 + 5 = 0. OK
