Step-by-step explanation:
rate of change formula
f(b) - f(a) / b-a
f (5)- f (1) / 12-0
5-1 / 12-0

Answer:
Step-by-step explanation:
Use the Pythagorean theorem to find the length x of the third side.
x² + 6² = √90²
x² = 90-36 = 54
x = √54 = 3√6
Answer:
Maximum number of students=41
Step-by-step explanation:
Total allotted=£2500
Regular theatre Tickets=£45
1/5 off= 4/5*45
=£36
Train tickets=£20 each
Total cost per person=£36+£20
=£56
If 3 teachers and maximum number of students attend
Let x=maximum number of students
Therefore
£56(x+3) <or= £2500
56x+168 <or= 2500
56x <or= 2500-168
56x <or= 2332
x <or= 2332/56
x<or=41.643
Maximum number of students that will go on the trip=41 students
Total money left over for the school=
Total allotted - cost per person multiplied by number of teacher+students
=2500 - 56(3+41)
=2500-56(44)
=2500-2,464
=£36
