Answer:
28
Step-by-step explanation:
3 Units = 84 books
1 Unit = 84/3
= 28 books
Since Fiction books is only represented by 1 unit,
there are <u>2</u><u>8</u><u> </u><u>F</u><u>i</u><u>c</u><u>t</u><u>i</u><u>o</u><u>n</u><u> </u><u>b</u><u>o</u><u>o</u><u>k</u><u>s</u>
Answer:
The answer to your question is: y = 6x + 3
Step-by-step explanation:
Data
slope = m = 6
A (8, 51)
Equation
y = mx + b
(y - y1) = m (x - x1)
(y - 51) = 6(x - 8)
y - 51 = 6x - 48
y = 6x - 48 + 51
y = 6x + 3
Isocoleese means that 2 sides and hence 2 angles are same measure
acute means that all 3 angles are less than 90 degrees
We can rule out choice I since acut means less than 90
II is a possibility, but it doesn't best describe it
III. that is true, but it doesn't include the isocileese part
IV. that is true, but doesn't include the acute part
not sure, either III or IV
By completing the square: x²-8x+19 = (x-4)²-16+19 = (x-4)²+3 so minimum point = (4,3)
By calculus: f'(x) = 2x-8. (minimum point occurs when f'(x)=0 therefore)
2x-8 = 0 means x=4 and the corresponding y value is 3.
The minimum value of this function (y) is 3 and this occurs when x = 4.
