Answer:
1min 1
Step-by-step explanation:
Y-intercept = -2
Note that your equation is in slope-intercept form. Slope-intercept form can represented by y = mx + b where m is the slope and b is the y-intercept.
First, all the heights have to be converted to similar units, say feet.
Therefore,
Building= 20 feet
Tree = 252*0.083333 = 21 feet
Flagpole = 6*3 = 18 feet
The tallest of the three is the tree and thus should cast the longest shadow. However, it should be noted that at exactly noon when the sun is overhead, all the three will have equal length of shadow (that is, 0 feet long).
60! 3.4(60)=204 so the answer is 60
