He isotope titanium-44 decays into scandium-44, with a half-life of 60 years. in a sample of titanium-44 containing 2 × 1010 atoms, how many titanium-44 and scandium-44 atoms would there be in the sample after 240 years?

There would be 1.25× 10 to the power 9 titanium-44 atoms. There would be 1.875× 10 to the power 10 scandium-44 atoms.

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
