6.4 because a circle from side to is the same no matter where u start from and b plus d equal 6.4
-4. 5 is the answer to your prollem
Answer:
The answer to your question is:
Step-by-step explanation:
Data
a)
C (0, 0)
D (7, 12)
m = (12 - 0) / (7 - 0)
m = 12/7
Slope = 12/7
b)
(y - y1) = m(x - x1)
(y - 12) = 12/7 (x - 7)
y - 12 = 12/7 x - 1
y = 12/7 x - 1 + 12
y = 12/7 x + 11
c)
Domain [0, 7]
Range [0, 12]
Answer:
So m= - 11
Step-by-step explanation:
* THe vertex is (-2,6), then the equation is y = a(x+2)^2 +6, a is to find out.
* A root is 7 means x=7 and y=0, then :
0 = a(7+2)^2 +6
0=81a+6 or a= -6/81 = -2/27.
* We have the equation: y= -2/27 (x+2)^2 +6=-2/27 [ (x+2)^2-81]
y= -2/27 (x-7)( x+11).
So m= - 11
Hope that you understand.
