Answer:
176 mm
Step-by-step explanation:
The circumference of a circle is the perimeter of a circle (length of a circle). The circumference of a circle is given as:
Circumference (C) = 2πr = πd, where d is the diameter
The circumference of a circle with diameter 7 mm is:
C = πd = 22/7(7) = 22 mm
The length of the paper to round the cylindrical pencil is the same as the perimeter of the pencil which is 22 mm.
To round the pencil 8 times, the length of the paper needed = 8 × 22 mm = 176 mm

Answer:
x ≈ 0.309906932381 or 4
Step-by-step explanation:
There are no algebraic methods of solving a mixed exponential and polynomial equation. The value of x can be found by guessing, or by other means such as trial and error or graphing.
Attached is a graph showing two solutions. x = 4 is the integer solution (2^4 = 4·4). The irrational solution is approximately x ≈ 0.309906932381. That precision is obtained by Newton's method iteration, easily done by a graphing calculator.
Slope is 1 bc u see where the points are and go up until u find the other point

Ironically, buying a lot at a time is cheaper than buying bit by bit. Places like Sam's Club specialise in having bulk supplies. People might not be planning to buy bulk, but after seeing how cheap it is, they'll decide to buy more than they planned. It creates the illusion of saving money to the consumer, but in reality, they spent more just because they liked the idea of getting more product. Hope that made since! :D
