Answer:
Step-by-step explanation:
The factored form of a quadratic is given by:
Where <em>p</em> and <em>q</em> are the zeros, and <em>a</em> is the leading coefficient.
The quadratic relation has zeros of 5 and 6, and it has a y-intercept of 30.
Since the zeros are 5 and 6, <em>p </em>and <em>q</em> are 5 and 6. Thus:
The y-intercept is 30. In other words, when <em>x </em>= 0, <em>f(x)</em> = 30:
Solve for a:
Therefore, our quadratic in factored form is:
To find the standard form, expand:
It is not a function if there is no pattern to the numbers
2(x^2 - 2x + 1) + 3
= 2x^2 - 4x + 2 + 3
= 2x^2 - 4x + 5

a, -14
Answer:
We can model the decimal number 1.7 by drawing two squares and divide each of the two squares into 10 equal parts.
Then we start shading the square such that the first square is fully shaded and in the second square we shade 7 out of the 10 parts such that 0.7 of the figure is shaded.
Hence, the total portion of the figures that are shaded are:
1+0.7=1.7
