Answer:

3(x+2)=0

3x+6=0

3x=-6

x=-2

for, (x+2)(x+2)=0

x2 +4x+4=0

x=-2 , or x=4

and is

a sample from a mummified bull was taken from a certain place. The sample shows that 71% of the carbon-14 still remains. how old

7nadin3 [17]

Answer:

Step-by-step explanation:

Decay of carbon - 14 is exponential in nature . It decays as follows .

$N=N_0e^{-\lambda t}$ λ is called decay constant .

λ = .693 / T where T is half life .

Half life of carbon-14 is 5700 years

λ = .693 / T

= .693 / 5700

= 12.158 x 10⁻⁵ year⁻¹

$N=N_0e^{-\lambda t}$

N = .71 N₀

$.71 N_0 =N_0e^{-\lambda t}$

$.71 =e^{-\lambda t}$

Taking ln on both sides

ln .71 = - λ t

ln .71 = - 12.158 x 10⁻⁵ t

-0.3425 = - 12.158 x 10⁻⁵ t

t = .3425 / 12.158 x 10⁻⁵

A professional baseball diamond is a square. The distance from base to base is 90 ft. To the nearest foot, how far does a catche

mamaluj [8]

BSE is square.

Let side be s

s=90ft

Diagonal be d

$\\ \tt\longmapsto s=\dfrac{d}{\sqrt{2}}$

$\\ \tt\longmapsto d=s\sqrt{2}$

$\\ \tt\longmapsto d=90\sqrt{2}$

$\\ \tt\longmapsto d=127ft$
