Answer:

(Unless I am understanding the question/lesson wrong I know how to do this)

Step-by-step explanation:

On the first set you can see that 1 is the time and 3 is the distance so you would go to the chart and where it says time you would go right one time and I think since it says distance you would be the point up 3 times to the chart would look like (1,3).

Hope this helps :)

In a lab experiment, the decay of a radioactive isotope is being observed. At the beginning of the first day of the experiment t

GaryK [48]

Using an exponential function, it is found that the mass of the radioactive sample at the beginning of the 13th day of the experiment was of 169.1 mg.

<h3>What is an exponential function?</h3>

A decaying exponential function is modeled by:

$A(t) = A(0)(1 - r)^t$

In which:

A(0) is the initial value.

r is the decay rate, as a decimal.

At the beginning of the first day of the experiment the mass of the substance was 500 grams and mass was decreasing by 8% per day, hence A(0) = 500, r = 0.08, and the equation is given by:

$A(t) = A(0)(1 - r)^t$

$A(t) = 500(1 - 0.08)^t$

$A(t) = 500(0.92)^t$

At the 13th day, the mass is given by:

$A(13) = 500(0.92)^{13} = 169.1$

Answer:

The answer is 1 2/3. (One and two thirds)

Step-by-step explanation:

-20 / -12

The negative signs will cross out.

Each number is able to divide by 4.

20 divided by 4 is 5.

12 divided by 4 is 3.

5/3 = 1 2/3

Find the solution(s) to x^2- 14x + 49 = 0.

malfutka [58]

Answer:

$\boxed{C. \: x = 7 \: only}$

Step-by-step explanation:

$= > {x}^{2} - 14x + 49 = 0 \\ \\ = > {x}^{2} - (7 + 7)x + 49 = 0 \\ \\ = > {x}^{2} - 7x - 7x + 49 = 0 \\ \\ = > x(x - 7) - 7(x - 7) = 0 \\ \\ = > (x - 7)(x - 7) = 0 \\ \\ = > {(x - 7)}^{2} = 0 \\ \\ = > x - 7 = 0 \\ \\ = > x = 7$
