The motion of the hour hand of a clock is a periodic motion that repeats every 12 hours.
- The equation that can be used to models the height as a function of time, based on the given options, is presented as follows;
Reasons:
The given parameters are;
The variation of the height of the tip of the hour hand = 9 feet to 10 feet
At t = 0, the time = 12.00 a.m.
Required: The equation that can be used to model the height as a function of time.
Solution:
The general form of the cosine function is presented as follows;
y = a·cos(b·x - c) + d
The amplitude = a
Therefore;
b = The cycle speed
The period, T, is given as follows;
The period of a block, T = 12 hours
Therefore;
At t = 0, H = The highest point = 10 ft.
Which gives;
-c = arcos(1) = 0
-c = 0
c = 0
The equation is therefore;
The above equation is the same as; <u>H = 0.5cosine (StartFraction pi Over 6 EndFraction t) + 9.5</u>

Answer:
- 36
- 64
- 100
- 10
Step-by-step explanation:
The area of a square is the square of the side length. Then the side length is the square root of the area.
- 6² = 36 . . . area of the square of leg 6
- 8² = 64 . . . area of the square of leg 8
- 36+64 = 100 . . . sum of the two leg squares = area of hypotenuse square
- √100 = 10 . . . hypotenuse length
Answer:
Step-by-step explanation:
Umm well mean you just have to use like terms. start by doing any math until there are no parenthesis, and then you basically just use like terms to solve it. (like if you have then you use like terms) I would need specifics to be able to evaluate more, but I hope this helps!
