Answer:
0.0625
Step-by-step explanation:
11^-x = 1/(11^x). if that equals four, 11^x = 0.25. 0.25^2 = (11^x)^2 = 11^2x. 0.25^2 = 0.0625. Hope this helps.
Answer and Explanation:
The vertex formula is derived from the completing-the-square process, just as is the Quadratic Formula. In each case, memorization is probably simpler than completing the square.) For a given quadratic y = ax2 + bx + c, the vertex (h, k) is found by computing h = –b/2a, and then evaluating y at h to find k.

The regression equation is (d) log(y) = 0.064x + 1.706
<h3>How to determine the regression equation?</h3>
The table of values is given as:
x 2 3 4 5 6
y 73 77 85 101 133
Calculate the logarithm of the y values.
So, we have:
x 2 3 4 5 6
log(y) 1.86 1.89 1.93 2 2.12
Next, we enter the above values in a regression calculator.
From the calculator, we have the following summary:
- Sum of X = 20
- Sum of Y = 9.8
- Mean X = 4
- Mean Y = 1.96
- Sum of squares (SSX) = 10
- Sum of products (SP) = 0.63
The regression equation is then represented as:
log(y) = bx + a
Where:
b = SP/SSX = 0.64/10 = 0.064
a = MY - bMX = 1.96 - (0.064*4) = 1.706
So, we have:
log(y) = 0.064x + 1.706
Hence, the regression equation is (d) log(y) = 0.064x + 1.706
