Answer:
B) 4
Step-by-step explanation:
We can solve this by observing some pattern.
The powers ending in 4 as unit digit are:
The exponents form the sequence:
2,6,10,14,20,...
We need to check if 62 belongs to this sequence.
This is an arithmetic sequence with a common difference of 4 and a first term of 2.
The explicit formula is
We equate this to 62 and solve for n.
Since n is a natural number, 62 belongs to the sequence.
Hence
will have a unit digit of 4.

Answer B
Answer:
Step-by-step explanation:
Given that a projectile is launched vertically upward from the ground with an initial velocity of 70 ft per sec
Neglecting air resistance, its height s (in feet) above the ground t seconds after projection is given by
When height = 10 feet we have to find the time
Hence substitute s = 10 ft
We may get two answers as
The first time is for going up and the second is for coming down.
Answer:
Step-by-step explanation:
Well certainly friction alone will not hold it there.
c² = a² + b²
15² = 14² + b²
15² - 14² = b²
b² = 29
b = √29 = 5.385164... = 5.39 ft
Answer:
hexagons are the only regular shapes which tessellate by themselves. You can have other tessellations of regular shapes if you use more than one type of shape. You can even tessellate pentagons, but they won't be regular ones. Tessellations can be used for tile patterns or in patchwork quilts!
