Rhett made a simple drawing of his house. it is a three dimensional figure with four faces that are rectangular and two that are
square. What kind of figure is it.
1 answer:
Answer: Rectangular prism
Step-by-step explanation:
Details culled from the information supplied :
1.) A 3 - dimensional figure
2.) Four rectangular faces
3.) Two square faces
Using the above information to form the basis of our inference, It could be inferred that the figure of Rhett's house is a rectangular prism.
Three dimensions: length, width, and height
Six faces in total; four of which are rectangular and 2 squared faces.

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>
