Answer:
The length of shadow decrease at 0.48 m/s.
Step-by-step explanation:
The distance of man from building = x
Thus initially, x = 12
It is given that dx/dt= -1.3 m/s
Let the shadow height = Y
Now solve for the 
when x=4
from the diagram (triangle) it can be seen similar triangles with similar base/height ratios.
Answer:
The slope of line A is C. 2
Step-by-step explanation:
You can check the slope by dividing the rise (how many units up) and the run (how many units across). This line has a rise of rise of 4 and a run of 2. Diving 4 by 2 gives you a slope of 2.
Quartile or interquartile.
Answer:
$12x + $33.75
Step-by-step explanation:
Okay so if you have (16x + 58.75) - (4x + 25)
first you add the common variables so... 16x - 4x = 12x
and 58.75 - 25 = 33.75
And 1 the most common mistake is that people add 25 and 58.75. The reason you don't do this is because the two equations are subtracting or trying to find the difference regardless of whether the numbers are positive or not. Although if they were negative numbers you would be adding.
I hope this helps :)
