According to the graph, what is the value of the constant in the equation below?
1 answer:
Option B: 50 is the value of the constant.
Explanation:
From the graph, the coordinates are ,
,
and
Where the x coordinates denotes the width and the y - coordinates denotes the height.
Also, given that
We need to determine the value of the constant
<u>Value of the constant:</u>
The value of the constant can be determined using the formula,
Since, all the coordinates lie on the same line, then all the coordinates have the constant.
Substituting the coordinate in the above formula, we get,
Therefore, the value of constant is 50.
Hence, Option B is the correct answer.

Answer:
d.
Step-by-step explanation:
To convert a root to a fraction in the exponent, remember this rule:
The index becomes the denominator in the fraction. (The index is the little number in front of the root, "n".) The original exponent remains in the numerator.
In this question, the index is 4.
The index is applied to every base in the equation under the root. The bases are 16, 'x' and 'y'.
To find the quad root of 16, input this into your calculator. Since 2⁴ = 16, = 2.
For the "x" and "y" bases, use the rule for converting roots to exponent fractions. The index, 4, becomes the denominator in each fraction.
