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:
Checkpoint B = (-9,5)
Step-by-step explanation:
Here is an image of the graph and coordinates.
Quotient rule says we can divide 192 and 3 because they are both under the radical. This gives us the square root of 64.
We can also divide x^3 and x to get x^2.
The square root of 64x^2 is 8x
Answer:
13
Step-by-step explanation:
Using Pythagoras Theorem:
Substitute values of a and b:
The length of the missing side is 13.
