Answer: 2</h3>
The lowest point has a y coordinate of 2. The highest point has a y coordinate of 6. The difference is 6-2 = 4. Cut this in half to get 4/2 = 2 which is the amplitude. This is the vertical distance from the midline (y = 4) to either the peak point or the valley point.
Standard form: Ax+By=C
first put in slope-intercept form:
slope = (0+5)/(6-3) = 5/3
pick point D: 0 = 5/3(6)+b -> b= -10
slope-intercept form: y=(5/3)x-10
multiply both sides by 3:
3y=5x-30
put in standard form:
5x-3y=30
Answer:
Step-by-step explanation:
2x to the power of 2 + x = ? When x=9
(2x)^2 + x
= 4x^2 + x
When x = 9
= 4(9)^2 + 9
= 4(81) + 9
= 324 + 9
= 333
