Answer:
72
Step-by-step explanation:
In order to find the acceleration we need first to defined it, so:
acceleration=((final velocity)-(initial velocity))/time interval
But (vf-vi) actually represents the velocity change, so (vf-vi)/dt represents the velocity change rate. This means that in our case:
In conclusion the acceleration is , without units just 72.
Answer:
36 trees were infected with the virus.
Step-by-step explanation:
Given:
Total number of trees = 90
Percentage of tree that had virus 40%
To find:
Number of tress that were infected by virus = ?
Solution:
Let the number trees that was affected by the virus be X.
then
X = 40% of 90
X =
X =
X= 36
Answer:
Explanation:
The given points are:
Since a <em>straight line joins</em> all the points, the equation that models the <em>relationship</em> is linear and you can find the slope-intercept equation which has the general form:
Where:
is the slope
is the y-intercept
<u>1. Find the slope</u>
You can use any two ordered pairs.
<u>2. Find the y-intercept</u>
The y-intercept is the value of y when x = 0; thus it is 275.
<u>3. Substitute in the slope-intercept equation</u>
That is the last option.
