Answer:
The length of metal band around the given clock is 50. 24 cm.
Step-by-step explanation:
Here, the diameter of given clock = 16 cm
Now, Diameter = 2 x Radius
So, Radius = D/2 = 16 cm/2 = 8 cm
⇒The radius of the clock = 8 cm
Now, The metal Band around it = The CIRCUMFERENCE of the watch
Circumference of the clock = 2 π r
= 2 x ( 3.14) x ( 8) = 50.24 cm
or, C = 50.24 cm
Hence, the length of metal band around the given clock is 50. 24 cm.
The ticket price which will maximize the student's council is: C. $3.10.
<h3>What is price?</h3>
Price can be defined as an amount of money which is primarily set by the seller of a product, and it must be paid by a buyer to the seller, so as to enable the acquisition of this product.
Based on the information provided about Valley High School student council, we can logically deduce the following data:
- Total number of students = 420 students.
- Lowest ticket price = $2.00.
- Increase in ticket price = $0.20.
- Attendance = 20 fewer students
<h3>How to determine the ticket price?</h3>
Mathematically, the equation which model the profit is given by:
Profit = price × number of tickets sold
P(x) = (2 + 0.2x)(420 - 20x)
P(x) = 840 + 84x - 40x - 4x²
P(x) = -4x² + 44x + 840.
For any quadratic equation with a parabolic curve, the axis of symmetry is given by:
Xmax = -b/2a
Xmax = -44/2(-4)
Xmax = -44/-8.
Xmax = 5.5
Ticket price for maximum profit is given by:
Ticket price = 2 + 0.2x
Ticket price = 2 + 0.2(5.5)
Ticket price = $3.10.

Parallel is MN and QP and perpendicular is MQ and OP
No because 0x14 would be 0 BUT it is still multiplication.
