Answer:
All the powers have a value of 1 because the exponent is zero.
Step-by-step explanation:
I surmised that from the two numbers I <em>could</em> seen
The residual value when x = 4 is 6.72 if the line of best fit to be y = 2.78x – 4.4
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more number and variables.
Given the function:
y = 2.78x - 4.4
When x = 4:
y = 2.78(4) - 4.4 = 6.72
The residual value when x = 4 is 6.72 if the line of best fit to be y = 2.78x – 4.4

Answer:
2.5 ft
Step-by-step explanation:
The figure for the given scenario is shown below.
There are two right angled triangles, ΔACD and ΔBCD
The height of flag staff is represented by segment AB, BC is the height of pedestal stand , D is a point on the ground that makes angles 30° and 60° with the bottom and top of staff at B and A respectively.
AB = 5 ft. Let the height of pedestal stand be 
ft and the distance of point D from the bottom of stand be 
ft as shown in the figure.
Now, from ΔACD,
From ΔBCD,
Plug in the value of in the first equation and solve for .
.
Therefore, the height of the pedestal stand is 2.5 ft.
