Answer:
9.75
Step-by-step explanation:
1.65 x5 is 8.25 then you add half of 1.65 which is .825 to get 9.75
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:
![h = 35d](https://tex.z-dn.net/?f=h%20%3D%2035d)
In this question:
Base diameter of 3.2m, so
, and the height is in meters.
![h = 35d = 35(3.2) = 112](https://tex.z-dn.net/?f=h%20%3D%2035d%20%3D%2035%283.2%29%20%3D%20112)
The approximated height of the tree is of 112 meters.
This is always ''interesting'' If you see an absolute value, you always need to deal with when it is zero:
(x-4)=0 ===> x=4,
so that now you have to plot 2 functions!
For x<= 4: what's inside the absolute value (x-4) is negative, right?, then let's make it +, by multiplying by -1:
|x-4| = -(x-4)=4-x
Then:
for x<=4, y = -x+4-7 = -x-3
for x=>4, (x-4) is positive, so no changes:
y= x-4-7 = x-11,
Now plot both lines. Pick up some x that are 4 or less, for y = -x-3, and some points that are 4 or greater, for y=x-11
In fact, only two points are necessary to draw a line, right? So if you want to go full speed, choose:
x=4 and x= 3 for y=-x-3
And just x=5 for y=x-11
The reason is that the absolute value is continuous, so x=4 works for both:
x=4===> y=-4-3 = -7
x==4 ====> y = 4-11=-7!
abs() usually have a cusp int he point where it is =0
Hope it helps, despite being this long!
