Answer:
= 80
Step-by-step explanation:
64000/80 = 80
From the data given, generate first the quadratic equation which best describe the height of the ball. The quadratic function has a general form of
f(x) = Ax^2 + Bx
Substituting the known data,
(1) 148 = A(1^2) + B(1)
(2) 272 = A (2^2) + B (2)
solving for A and B simultaneously,
A = -12
B = 160
To answer this problem, substitute 6 to x. Thus, after 6 seconds, the height is 528 feet.
Answer:
2 units because there is no change in size.
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
Answer:5.38
Step-by-step explanation:
From Pythagoras principle
radius=√(3.6^2+4^2)
radius=√(3.6x3.6+4x4)
radius=√(12.96+16)
radius=√(28.96)
radius=5.38
