Answer:
40.5 square feet
Step-by-step explanation:
The formula for finding the area of a rhombus is (diagonal 1 x diagonal 2)/2. Since you're given the side of the rhombus, you can use the 45:45:90 degree triangle rule where the measure of the sides is 1:1: to find the diagonals (both equal 9 feet).
9x9/2 = 81/2 = 40.5
Hope this helps!
Answer:
Step-by-step explanation:
A way to find the inverse function is to swap the x and y (f(x)) in the equation.
We can check that it is an inverse function by using a property of inverse functions:
If we plug in the f(x) function into the variable x of the inverse function, we should end up with x
It checks out!
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
