Answer:
Slope, m = 1100
y-intercept,c = 2491
Step-by-step explanation:
We are given the following in the question:
The above gives the altitude of the airplane above the sea level in feet(y) after x minutes since the take off.
Comparing the above equation, to a general linear equation, we have,
where m is the slope and c is the y-intercept.
Comparing we get,
Slope, m = 1100
y-intercept,c = 2491
Interpretation:
- The slope of equation tells us about the rate of change of function with unit increase in value of x. Thus, the altitude of airplane increases 1100 feet when the time increases by 1 minute.
- The y-intercept is the value of y when x is 0. Thus, the altitude of airplane is 2491 feet when the airplane has not taken off.
<u>Ashely have </u><u>56 ways</u><u> to choose from</u>
This question can be solved using a system in mathematics called Permutation and it's in a topic of mathematics called combinatorics.
<h3 /><h3>Permutation</h3>This is the process of arranging a particular set of data in different ways.
Since Ashely is choosing 3 desserts out of 8 in no specific ways
Where n = total number of ways available
r = total numbers that would be selected.
Data given
- n = 8
- r = 3
Let's substitute these values into the equation.
From the calculation above, Ashley have 56 ways in which can choose 3 dessert from an 8 choice.
