Answer:
1.11
Step-by-step explanation:
First, you ignore the absolute value sign and subtract normally: –9.23 – 1.79 = -11.02, –7.34 – 2.57 = -9.91. Then now you add the absolute value to the numbers: |-11.02| - |-9.91| = 11.02 - 9.91 = 1.11.
Answer:
(6,12)
Step-by-step explanation:
Substitute the value of y into y=2x:
x+6=2x
x=6
Substitute x into the equation of y=2x
y = 2*6 = 12
(6,12)
we are given

where
F is the number of board feet
d is the diameter (in inches) of the log
Since, we have to minimize F
so, firstly we will find it's derivative


now, we can set it to 0
and then we can solve for d


so, we get diameter as

Both triangles area:
4.2 x 8.2 = 34.44
you don’t need to divide by two cause there’s two triangles anyways.
also, you get 8.2 by subtracting the total length by the top length. (13.5-5.3)
rectangle:
4.2 x 5.3 = 22.26
the total area is 56.7cm squared
