Answer:
About 0.559 seconds
Step-by-step explanation:
The height equation is:
Where is the initial height of the book, which is 5, so we can write:
Now, we want time it took for the book to reach ground (h = 0)
So, we substitute h = 0 and solve for t:
It took about 0.559 seconds for the book to reach the ground
We have a number .
To write it as a fraction first count the number of decimals and call it (which, in our case, has a value of 3). Multiply the number with
to get
. Then divide this number by
to get
from here you can either simplify (if the assignment says so, then the simplified fraction is
) or not.
Hope this helps.
Answer:
belongs to the line
. Please see attachment below to know the graph of the line.
Step-by-step explanation:
From Analytical Geometry we know that a line is represented by this formula:
Where:
- Independent variable, dimensionless.
- Dependent variable, dimensionless.
- Slope, dimensionless.
- y-Intercept, dimensionless.
If we know that ,
and
, then we clear slope and solve the resulting expression:
Then, we conclude that point belongs to the line
, whose graph is presented below.
The equation is y = 2x - 12
<h2>Explanation</h2>Equation in slope intercept form is
Where,
m = slope
b = y-intercept
Putting the value of slope in this equation:
From this we can solve the equation for b
Now, the equation of y-intercept becomes
