Answer:

PEMDAS

Step-by-step explanation:

Use PEMDAS. Parenthesis, Exponents, Multiplication/Division, Addition/Subtraction.

Start with your parenthesis, which is (9-6). This comes out to 3. Your equation should now look like 2+(3)x5/3

Then, go to your exponents. Since we don't have any, we skip this step.

Now, we look from left to right for any multiplication symbols or division symbols. Finding (3)x5, this comes out to 15. Now rewrite your equation, if should look like this: 2+15/3.

Repeat the last step and find your division symbol, and find this 15/3. That comes out to 5.

The last step is finding addition or subtraction symbols, and since there's only two numbers left we can just solve the problem from here.

2+5=7.

What percent of a present amount of radioactive radium (226Ra) will remain after 1200 years? The half life of 226Ra is 1599 year

sp2606 [1]

Answer:

59.44%

Step-by-step explanation:

$M_{R} = \frac{M_{O} }{2^{n} }$

$n=\frac{t}{t\frac{1}{2} }$

Where $M_{R}$ = mass remaining

$M_{O}$ =original mass.

t= time

$t\frac{1}{2}$ =half life

$t\frac{1}{2}$ =1599, t= 1200, $M_{O}$ =226, $M_{R}$ =?

$n=\frac{1200}{1599}$

n= 0.750469

$M_{R} = \frac{226}{2^{ 0.750469} }$

$M_{R}$ =134.3367amu

percentage of mass remaining = $\frac{134.3367amu}{226amu}$ *100%

= 59.44%

Using it's concept, the range of the given exponential function is:

C. 0 < y ≤ 46638.

<h3>What is the range of a function?</h3>

The range of a function is the set that contains all possible output values for the function.

In this problem, the function is:

y = 46,638(0.78)^x.

It is an exponential function with initial value 46,638 and rate of change 0.78. Exponential functions that are not shifted down, such as this one, are never negative nor zero, hence the range also has the restriction y > 0, and is given by:

C. 0 < y ≤ 46638.
