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:
(x,y) -> (-x,-y)
Step-by-step explanation:
the coordinates are switched from the (x,y) you have to (-x,-y)
Four $5 bills and two $1 bills
In total it’s six bills
5(4)=20 and 1(2)=2
20+2=22
49
3+4 is 7
and squared is 2
7x7=49
Answer:
C: Either the mean or median; both are 5
Step-by-step explanation:
MEAN: 5+2+4+8+6= 25 = 25/5= MEAN IS 5
MEDIAN: put it in order: 2,4,5,6,8
cross out 2,8,4,6
left over number is 5
So median is 5
