Your slope is 2 and your Y-intercept is 0.
To graph, plot the dot at 0 and the slope is by 2
Answer:
The percentage rate of decay per year is of 3.25%.
The function showing the mass of the sample remaining after t is 
Step-by-step explanation:
Equation for decay of substance:
The equation that models the amount of a decaying substance after t years is given by:

In which A(0) is the initial amount and r is the decay rate, as a decimal.
Every 21 years, its mass decreases by half.
This means that
. We use this to find r, the percentage rate of decay per year.



![\sqrt[21]{(1-r)^{21}} = \sqrt[21]{0.5}](https://tex.z-dn.net/?f=%5Csqrt%5B21%5D%7B%281-r%29%5E%7B21%7D%7D%20%3D%20%5Csqrt%5B21%5D%7B0.5%7D)



The percentage rate of decay per year is of 3.25%.
Given that the initial mass of a sample of Element X is 80 grams.
This means that 
The equation is:



The function showing the mass of the sample remaining after t is 
Answer:
Distance between two point = 3.6 (Approx.)
Step-by-step explanation:
Given:
Coordinate;
(-4, -6) and (-1, -4)
Find:
Distance between two point
Computation:
Distance between two point = √(x1 - x2)² + (y1 - y2)²
Distance between two point = √(-4 + 1)² + (-6 + 4)²
Distance between two point = √(-3)² + (-2)²
Distance between two point = √9 + 4
Distance between two point = √13
Distance between two point = 3.6 (Approx.)
The answer is (-2, 8) and (2, -8)
Answer:
total = 0;
for (k = 0; k <= n; k++)
total += Math.pow(k,3);
Step-by-step explanation:
Here the variable total is declared and initialized with a value zero
Then a for loop is defined with a counter k whose initial value is set to zero then a condition for the loop is that the counter k does not exceed n k<=n and then within the loop a statement which add the cube of the counter k to the variable total and still assigns it to the variable total is defined
total += Math.pow(k,3);
What this program does is to obtain the sum of the cubes of k
