.17 because there is a zero behind the 7! .170 and .165. .17 is bigger
Domain means the values of independent variable(input) which will give defined output to the function.
Given:
The height h of a projectile is a function of the time t it is in the air. The height in feet for t seconds is given by the function
Solution:
To get defined output, the height h(t) need to be greater than or equal to zero. We need to set up an inequality and solve it to find the domain values.

Conclusion:
The domain of the function is the time in between 0 to 6 seconds
The height will be positive in the above interval.
Answer:
No, because it does not have a constant rate of change.
Step-by-step explanation:
On the <em>x</em><em> </em>side of the table, there is a constant rate of change (+1). However, on the y side, it is not. The first change is +7, the next +5, and the last +6. The rate of change has to be constant on both sides for the table to be considered linear.
Answer:
Classify by angles: <u>Equiangular</u>
Classify by sides: <u>Equilateral</u>
Step-by-step explanation:
An equiangular triangle has angles that all measure 60 degrees. An equilateral triangle is a triangle that has sides will all of the same lengths. This triangle meets both of these requirements.
