The value of a motorbike depreciates by 32% per year. Work out the current value of a motorbike bought 5 years ago for £3600
DaniilM [7]
\bf \qquad \textit{Amount for Exponential Decay}
\\\\
A=P(1 - r)^t\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{initial amount}\to &3600\\
r=rate\to 32\%\to \frac{32}{100}\to &0.32\\
t=\textit{elapsed time}\to &5\\
\end{cases}
\\\\\\
A=3600(1-0.32)^5\implies A=3600(0.68)^5\implies A\approx 523.41601

write the equaion of a line in slope-intercept form if the slope is 1/5 and the y-intercept is -9 explain please
faust18 [17]

Answer:

y = \frac{1}{5} x - 9

Step-by-step explanation:

The slope-intercept form is y = mx + b, where:

m = slope

b = y-intercept.

The slope (m) tells you the steepness of the line. It is the average rate of change which measures how the y-value changes for each one-unit change in the x-value. Hence, slope = \frac{rise}{run}.  So the given slope of 1/5 means that for every 1 unit change in the y-value, the x-value changes by 5 units (you go up 1 unit, and "run" 5 units to the right).

Next, the y-intercept is the point on the graph where it crosses the y-axis, and has the coordinates, (0, b). It is also the value of y when x = 0. Since you're given the y-intercept of -9, then that means that it is the y-coordinate of (0, <em>b</em>). So, it becomes (0, -9).

Now that we have our slope (<em>m </em>) = 1/5, and the y-intercept (<em>b </em>) = -9, we can write the equation of the line as:

y = \frac{1}{5} x - 9

(I'm also including a screenshot of the line where it shows the y-intercept of (0, -9) on the graph).

Sara put 7 boxes in her closet. Each box is for holding a different type of seashell. So far, there are 0 shells in each box. Ho
user100 [1]

Given that Sara put 7 boxes in her closet.

So number of boxes = 7

Then it says that each box is for holding a different type of seashell. So far, there are 0 shells in each box.

So the number of seashell in 1 box = 0


We need to find about how many shells does Sara have.

To find that we will just multiply (number of boxes) by (number of seashell in 1 box). Which is given by 7 times 0.


we know that product of a number and 0 is always 0.

Hence final answer is 0 seashell.
