Answer:
B
Step-by-step explanation:
<u>Slope-intercept form:</u>
y= mx +c, where m is the slope and c is the y-intercept.
Given that the slope is -4/5,
To find the y-intercept, substitute a pair of coordinates.
When x= -5, y= -4,
Thus, the equation of the line is
Answer:
The ladder should be 34 feet long.
Step-by-step explanation:
The height of the spotlight above ground = 30 feet
The base of the ladder will be = 16 feet from the base of house
We can easily assume this to be a right triangle with perpendicular as 30 feet and base as 16 feet and we have to find the hypotenuse.
Lets say the length of the ladder or hypotenuse is = x
We will apply Pythagoras theorem here.
=>
=>
=>
So, x = 34
Hence, the ladder should be 34 feet long.
The box plot for the set of data
<span>43, 48, 52, 61, 74, 81, 40, 42, 56, 77, 81, 43
</span>will be found by rewriting the data in ascending data, then plotting it. This will give us the box plot in the attached figure.
