The half-life of carbon 14 is years. How much would be left of an original -gram sample after 2,292 years? (To the nearest whole

lozanna [386]

Answer:

A = 0.75 gram or 1 gram

Step-by-step explanation:

The half-life of carbon 14 is years. How much would be left of an original -gram sample after 2,292 years? (To the nearest whole number).

We can use the following formula for half-life of $^{14}C$ to find out how much is left from the original sample after 2,292 years:

$A = A_{0}e^{-0.000124t}$

where:

A is the amount left of an original gram sample after t years, and

$A_{0}$ is the amount present at time t = 0.

The half-life of $^{14}C$ is the time t at which the amount present is one-half the amount at time t = 0.

If 1 gram of $^{14}C$ is present in a sample,

Solve for A when t = 2,292:

Substituting $A_{0}$ = 1 gram into the decay equation, and we have:

$A = A_{0}e^{-0.000124t}$

$A = A_{0}e^{-0.000124(2,292)}$

A = 0.75 g or 1 g

Nine less than the product of 6 and a number is equal to 8

Romashka-Z-Leto [24]

Answer:

2.83

Step-by-step explanation:

You want to add 9 to 8 to get 17. 6 times a number must therefore equal 17. You can use the opposite which is division and divide 17 by 6 to get 2.83.

Factor each trinomial. Then match the polynomial (term) on the left with its factored form (definition) on the right.

zaharov [31]

Answer:

Step-by-step explanation:

The given equation is:

$x^{2}-8x-20$

Simplifying the above equation, we get

$x^{2}-10x+2x-20$

$x(x-10)+2(x-10)$

$(x+2)(x-10)$

therefore, the equation $x^{2}-8x-20$ matches with (B) $(x+2)(x-10)$ .

The given equation is :

$x^{2}+8x-20$

Simplifying the above equation, we get

$x^{2}+10x-2x-20$

$x(x+10)-2(x+10)$

$(x-2)(x+10)$

therefore, the equation $x^{2}+8x-20$ matches with (D) $(x-2)(x+10)$

The given equation is:

$x^{2}-x-20$

Simplifying the above equation, we get

$x^{2}-5x+4x-20$

$x(x-5)+4(x-5)$

$(x+4)(x-5)$

therefore, the equation $x^{2}-x-20$ matches with (A) $(x+4)(x-5)$ .

The given equation is:

$x^{2}-9x-20$

This equation ca't be firther simplified or factorised, thus the equation $x^{2}-9x-20$ matches with (C) Prime.
