Suppose you are offered just one slice from a round pizza (in other words, a sector of a circle). The slice must have a perimete
schepotkina [342]
The answer is diameter: 32 in, area: 64 in²

The perimeter of a sector of a circle is:
P = 2r + l
l = r<span>θ
P = 2r + r</span>θ<span>

P = 32 in
32 = 2r + r</span><span>θ
</span>32 - 2r = r<span>θ
</span>θ = (32 - 2r)/r
θ = (2*16 - 2*r)/r
θ = 2(16 - r)/r<span>

Area of the sector of the circle is:
A = r</span>²/2 * θ
A = r²/2 * 2(16 - r)/r
A = r² * (16 - r)/r
A = r(16 - r)
A = 16r - r²

For the maximum area:
A' = 16 - 2r
A' = 0
16 - 2r = 0
16 = 2r
r = 8 in

The diameter (D) of the circle is twice of the radius:
D = 2r = 2 * 8 = 16 in

The maximum area is:
A = 16r - r²
r = 8 in
A = 16 * 8 - 8²
A = 128 - 64
A = 64 in²

For what values of p is the value of the binomial 1.5p−1 smaller than the value of the binomial 1+1.1p?
djverab [1.8K]

Answer:

  p < 5

Step-by-step explanation:

We want to find p for ...

  1.5p -1 < 1 +1.1p

  0.4p < 2 . . . . add 1-1.1p

  p < 5 . . . . . . . multiply by 2.5

The desired relationship will be the case for values of p less than 5.
