In the graph is shown: x-axis is the hours that student spend studying for the test and y-axis is a grade obtained by student. The best fit equation is y=3.75x+52.5.
If student spend 0 hours, then x=0 and y=3.75*0+52,5=52.5. It is that the student most likely earn <span>grade of 52.5 in the test. </span>
The average rate of change in h(t) between t = 1 second and t = 3 is:
(h(3) - h(1))/(3 - 1) = ((3 + 70*3 - 16*3^2) - (3 + 70*1 - 16*1^2))/2 = 6
The average rate of change in h(t) between t=1 and t=3 tells us that that average speed between these points is 6 ft/s.
Answer: First option is correct.
Step-by-step explanation:
A number in an expression is a term that contains no variables.
So, it is known as constant term.
if any term is with variable or variables, then it can't be consider as a number.
Then, it becomes only a term.
But if there is no variables in a term is present, then it is called to be number.
Hence, First option is correct.
