Answer:
y= -4x^2 + 15x - 14
Step-by-step explanation:
A parabola is always in the form y = ax^2 + bx + c.
Substitute each point to produce different equations:
-14 = 0a + 0b + c = c
so c = -14
-3 = a1^2 + b1 + c = a + b - 14
so a + b = 11
0 = a2^2 + b2 + c = 4a + 2b -14 = 0
so 4a + 2b = 14
if we double a + b = 11 we get 2a + 2b = 22
Subtract this from 4a + 2b = 14 and we get 2a = -8 so a= -4 and b = 11 - a = 15
We don't need to use the (3,5) points as we have all the information we need.
Answer:
C. 8
Step-by-step explanation:
still using the equation a^2 = b^2 = c^2
Answer:
y = 90
Step-by-step explanation:
Since, e || f and a || b
Therefore, quadrilateral so formed is a rectangle.
Each angle of a rectangle is right angle.
The answers are f = 2 and p = -2
