What does the quotient rule of exponents say?
jenyasd209 [6]
It says that you need to divide 2 exponents with the same base, you keep the base and subtract the powers, its kind of like reducing fractions! :)

Element X decays radioactively with a half life of 12 minutes. If there are 160
Salsk061 [2.6K]

Answer:

It would take 75.8 minutes for the element to decay to 2 grams.

Step-by-step explanation:

The number of grams of element x, after t minutes, is given by the following equation:

X(t) = X(0)(1-r)^{t}

In which X(0) is the initial amount and r is the decay rate.

There are 160 grams of Element X

This means that X(0) = 160.

So

X(t) = X(0)(1-r)^{t}

X(t) = 160(1-r)^{t}

Half life of 12 minutes.

This means that X(12) = 0.5*X(0) = 0.5*160 = 80. So

X(t) = 160(1-r)^{t}

80 = 160(1-r)^{12}

(1 - r)^{12} = 0.5

\sqrt[12]{(1 - r)^{12}} = \sqrt[12]{0.5}

1 - r = 0.9438

So

X(t) = 160(1-r)^{t}

X(t) = 160(0.9438)^{t}

How long would it take for the element to decay to 2 grams?

This is t for which X(t) = 2. So

X(t) = 160(0.9438)^{t}

2 = 160(0.9438)^{t}

(0.9438)^{t} = \frac{2}{160}

\log{(0.9438)^{t}} = \log{\frac{2}{160}}

t\log{0.9438} = \log{\frac{2}{160}}

t = \frac{\log{\frac{2}{160}}}{\log{0.9438}}

t = 75.8

It would take 75.8 minutes for the element to decay to 2 grams.

-78 IS GREATER THAN OR EQUAL TO - 8 +5n
Leto [7]

Answer:

n\le -14.

Step-by-step explanation:

The statement "-78 IS GREATER THAN OR EQUAL TO - 8 +5n" mathematically can be written as

-78\ge -8+5n.

Add 8:

-78+8\ge -8+8+5n,\\ \\-70\ge 5n.

Divide by 5:

-\dfrac{70}{5}\ge n,\\ \\-14\ge n

or

n\le -14.
