Find p such that p+1=2x^2, p^2+1=2y^2. Know that p is a prime, x and y are positive integers.

Charra [1.4K]

Answer:

Step-by-step explanation:

Given p + 1 = 2 $x^{2}$ → 1 = 2 $x^{2}$ - p

$p^{2} + 1 = 2y^{2}$

$p^{2} + (2x^{2} - p) = 2y^{2}$

$p^{2} - p + (2x^{2} - 2y^{2} ) = 0$

The above equation is quadratic in p.

p = [ -(-1) ± $\sqrt{(-1)^{2} - 4* 1*(2x^{2} - 2y^{2} )$ ] ÷ 2

p = [1 ± $\sqrt{1 - 8(x^{2}-y^{2} )}$ ] ÷ 2

The figure shows a grapefruit half. The radius to the outsideof the rind is 5 cm. The radius to the inside of the rind is 4 cm.T

Marysya12 [62]

Answer:

the volume of the inside of half grapefruit is ( 128/3) pi the volume of 1 of the 12 segments is (32/9) pi

Step-by-step explanation:

The volume of half a sphere (hemisphere) is (2/3) pi r^3

(2/3) 4^3 pi = (2/3)(64)pi = (128/3) pi -

The volume of one of the 12 segements is the answer divided by 12

128/36 pi =( (32/9) pi
