Answer:
miles per minute represents the speed of the bird and 3 miles represents the original distance of the bird from its nest.
Step-by-step explanation:
As there is no graph mentioned here but the information are quite sufficient to answer the question.
We have points
From these points we can find the slope of the line .
From point slope formula
And assigning and
This slope is also the speed of the bird which is
As by plugging the values of any coordinate point we can confirm this.
Lets put , y-axis is the distance so in
minutes the the distance covered by the bird must be equal to to y-axis value which is
miles.
Now as in the bird has started from y-intercept value
so we can say that,the original distance of the bird from its nest is
.
So the correct choices are: and
The birds speed is per minute and is
away from its nest.
<u>Answer:</u>
29 years
<u>Step-by-step explanation:</u>
- Given the function
, where x stands for the number of years since the material was put into the vault, we can plug 140 into x to find the amount leftover.
- Another way of doing this is to change the function to
which are equivalent functions, and then plug 140 into x. This function is helpful if you also needed to find the rate.
- I'll use the 1st function because the question doesn't ask for the rate
From here I'll just use a calculator & get 28.7, or 29 years.
