Answer:
-3 < x ≤ 7
Step-by-step explanation:
Domain is the set of x-values that can be inputted into function f(x).
We can see from the graph that our x-values that can be inputted are from -3 to 7. Since -3 is an open dot, we cannot include this in our domain.
∴ -3 < x ≤ 7
The answerd is 197 because I estamited 37X5 to 40X5 is 200 than 200-3 is 197
Answer: 672 feets
Step-by-step explanation:
Using the solution diagram attached, the vertical height, h of the lighthouse ;
Using trigonometry :
Tanθ = opposite / Adjacent
Tan 2 = h / 804
h = tan 2 * 804
h = 28.076 feets
Using h, we can obtain the distance CB :
Tan θ = opposite / Adjacent
Tan 2 = 28.076 / CB
CB = 28.076 / Tan 12°
CB = 132.08860 feets
Distance between A and B
804 - 132.08860
= 671.9 feets
By using Microsoft excel to plot the data on a scatter plot, the linear regression equation can best be represented by: A. y = 12.11.1.36^x
<h3>What is a regression line?</h3>
A regression line can be defined as a statistical line that best describes the behavior of a data set and such, it is a line that best fits a set of data.
By using Microsoft excel to plot the data on a scatter plot, we can logically deduce that linear regression equation for the x-values and log(y)-values is given by:
y = 12.11.0.30^x
Thus, it can best be represented by: y = 12.11.1.36^x
