Answer:
X-intercept
Step-by-step explanation:
A "zero" of a function is thus an input value that produces an output of 0. An alternative name for such a point (x, 0) in this context is an x-intercept.
Answer:
24 feet
Step-by-step explanation:
We are given that an open box is to be constructed from a square piece of sheet metal by removing a square side 6 feet from each corner and turning up the edges.
We have to find the dimensions of the sheet metal
Let x feet be the side of square metal sheet
Length of box=x-12 feet (because 6 feet removed from each corner)
Width of box=x-12 feet
Height of box=6 feet
Volume of box=864 cubic feet
We know that volume of cuboid=
Box is in cuboid shaped
Therefore, volume of box=
Then ,
x=0 is not possible because side of square metal sheet can not be zero
Therefore, x=24
All sides of square metal sheet are equal.
Hence, side of square metal sheet =24 feet
by find f(-1) do u mean x=-1? if that's the case then the problem looks like -11(-1)+2=13 OR are we solving for f??? If we are solving for F then do this:
f(−1)=(−11)(−1)+2
Step 1: Simplify both sides of the equation.
f(−1)=(−11)(−1)+2
−f=11+2
−f=(11+2)(Combine Like Terms)
−f=13
−f=13
Step 2: Divide both sides by -1.
−f/−1=13/−1
f=-13
