Answer:
The approximated height of the tree is of 112 meters.
Step-by-step explanation:
The height of a tree with a base diameter of d meters is approximated by the following formula:

In this question:
Base diameter of 3.2m, so
, and the height is in meters.

The approximated height of the tree is of 112 meters.
0.74=74/100=37/50 in simplest form.
Answer:
Step-by-step explanation:
I believe that this is the answer.
Hi,
Perimeter AEDCB=3*10+15+20=65 (units)
Ratio of the similitude r*15=21==>r=21/15=1.4
Perimeter RQPTS=65*1.4=91(units)
Option B:
sin x = 1 is the equation represented by the intersection of the graph.
Solution:
The graph lies between -1 and 1 in y-axis.
x-axis of the graph is all real numbers.
The graph oscillates between -1 and 1 and a shape that repeats itself every 2π units.
That is the domain of the graph is all real numbers.
The range of the graph is [-1, 1].
It clearly shows that, it is the graph of sinx = 1.
Hence sin x = 1 is the equation represented by the intersection of the graph.
Option B is the correct answer.
