ANSWER

The three expressions are

V = 2(9 - {b}^{3} )(9 + {b}^{3} )

EXPLANATION

We were given the volume in cubic units to

V = 162 - 2 {b}^{6}

If we factor 2, we get,

V = 2(81 - {b}^{6} )

The expression in parenthesis is a difference of two squares. But you may not recognize it at first sight.

V = 2( {9}^{2} - ({b}^{3})^{2} )

This further gives us.

V = (2)(9 - {b}^{3} )(9 + {b}^{3} )

Heron’s formula: Area = Triangle PQR has sides measuring 9 feet and 10 feet and a perimeter of 24 feet. What is the area of tria
VladimirAG [237]
Hello,

Let's assume a,b,c the 3 sides of the triangle.

a=9
b=10
c=24-a-b=5

p= \dfrac{a+b+c}{2} =12\\

S= \sqrt{p(p-a)(p-b)(p-c)} = \sqrt{12*3*2*7} = \sqrt{504} =22,4499...\approx{22}

Element X is a radioactive isotope such that every 51 years, its mass decreases by half. Given that the initial mass of a sample
pychu [463]

Answer: It will take 6 years for 7500 grams of X to reach 6900 grams.

Step-by-step explanation:

Expression for rate law for first order kinetics is given by:

t=\frac{2.303}{k}\log\frac{a}{a-x}

where,

k = rate constant  

t = age of sample

a = let initial amount of the reactant  

a - x = amount left after decay process  

a) for completion of half life:  

Half life is the amount of time taken by a radioactive material to decay to half of its original value.

51=\frac{0.69}{k}

k=\frac{0.69}{51}=0.0135years^{-1}

b) for  7500 g to reach to 6900 g

t=\frac{2.303}{0.0135}\log\frac{7500}{6900}

t=6years

It will take 6 years for 7500 grams of X to reach 6900 grams.
