Unknown side = square root (100 - 49)
unknown side = square root (51)
unknown side = 7.14
The equation of the quadratic function that models the data is y = x^2 + 3x + 4
<h3>How to determine the scatter plot?</h3>
A quadratic function is represented as:
y = ax^2 +bx + c
Next, we enter the data values on the table to a graphing calculator.
From the graphing calculator, we have:
a = 1, b = 3 and c = 4
Substitute these values in y = ax^2 +bx + c
So, we have
y = x^2 + 3x + 4
Hence, the equation of the quadratic function that models the data is y = x^2 + 3x + 4 and the scatter plot is (a)

Answer:
A. ¹/₁₄ lb
Step-by-step explanation:
¹/₁₆ lb sand goes with ⅞ lb compost.
For 1 lb compost, the mass of sand needed is:
1 lb compost × (¹/₁₆ lb sand)/(⅞ lb compost).
We must evaluate the fraction (¹/₁₆)/(⅞).
Invert the denominator and multiply
(¹/₁₆)/(⅞) = ¹/₁₆ × ⁸/₇ Cancel the 8s
= ½ × ⅐ Multiply numerators and denominators
= ¹/₁₄
For 1 lb of compost, the mass of sand needed is ¹/₁₄ lb.
