Answer:
C. 9
Step-by-step explanation:
The vertex form of the function is given by;
where is the vertex of the parabola.
We substitute a third point say, (3,5) to find the value of a;
The function is
The average rate of change for the interval x=5 to x=6 is
Answer:
x stays x in both equations so x stands for x
Step-by-step explanation:
y=3x+6
you can put this into a graphing caculator or draw it yourself.
6 is the y value when x equals 0. and the 3 represents the slope so then it is solved for any y value
Answer:
y=2x -12
STANDARD FORM: 2x-y= 12
Step-by-step explanation:
Find the angle in degrees first:
Substitute 180 for pi.
(5 x 180) / 4
900 / 4
= 225 degrees
Now, the angle that has the same sin value of 225 is the angle's reference angle, or the angle that it makes with the x-axis.
225-180 = 45
45 is the angle that shares the same sin value
Answer: 45 degrees
Hope this helps :)
