The paths will cross when the coordinates are (1,9) and (4, 15).
<h3>What is a model?</h3>
A model is a representation of reality. Now we have that the path of the frisbee is y = -x² + 7x + 3 while the path of the dog is y = 2x + 7.
The both paths will cross when;
-x² + 7x + 3 = 2x + 7
-x² + 5x - 4 =0
x=1 or x=4
If x = 1, y = 2(1) + 7 = 9
If x = 4, y = 2(4) + 7 = 15
Thus the paths will cross when the coordinates are (1,9) and (4, 15).

Answer: 28.
Step-by-step explanation:
The median of a data set is defined as the middle value of a data set.
For instance, the median of the data set [4, 7, 8] would be 7 because it is the "middle value".
You can find this by sorting the numbers by smallest to largest:
2, 9, 15, 16, 21, 24, 28, 32, 34, 35, 37, 39, 40
There are 13 numbers in the set, so you can exclude the first 6 and last 6 numbers from the set to get your median, 28.

Answer:
Step-by-step explanation:
A line has the following slope-intercept equation:
In which a is the slope.
Write the equation of a line that has a slope of -3 and passes through the point (1.25, -4).
Slope of -3 means that . So
Passes through the point (1.25, -4). Means that when
So
the answer is false because y= 0
