Answer:
27
Step-by-step explanation:
30%=0.3 in decimal form
90×0.3=27
80*4=320-(71+80+86)=83 So 83 needs to be added.
Answer:
y = (x - 3)² - 4 Vertex form
(3, -4) Vertex
Step-by-step explanation:
f(x) = x² - 6x + 5
Complete the square
y = (x - 3)² + 5 - (-3)²
y = (x - 3)² + 5 - 9
y = (x - 3)² - 4 Vertex form
(3, -4) Vertex
Answer:
Use the slope formula (y2-y1)÷(x2-x1)
Step-by-step explanation:
(-5-(-3))÷2-3
= (-2.5,-1)
The graph of 
is given by,
Here given the function is 
when 
, then it passes through the origin (0,0).
When 
Since we know that, 
, then the function has maximum height at 
.
Again when 
, again the function is 0.
So clearly the function is the Oscillating function.
Using graphing calculator we get the graph of function 
,
