Answer:
(2pi)/5
Step-by-step explanation:
The cosine function cos(x) has a period of 2*pi.
If we change the argument of the cosine, the new argument will have a period of 2*pi. If the new argument is 5x, we have that the period will be:
5x = 2*pi
x = 2*pi/5
The period of this function will be (2pi)/5, because for every (2pi)/5 change in the value of x, the function will have the same value. The value of 5 multiplying the cosine does not interfere in the period.
Answer:
6 cm
Step-by-step explanation:
wire was bent into the shape of a rectangle with width 5 and length 7. If this wire is bent into shape of a square, what is the length of a side of the square
Given that:
Rectangular wire with the following dimension :
Width = 5
Length = 7
To obtain the total length of the wire :
Perimeter of rectangle :
2 (length + Width)
2 (5 + 7)
2(12)
= 24 cm
The length of each side of the square will be :
Number of sides = 4
Length of each side :
24 / 4 = 6 cm
In decimal form that is 2.03125, in fraction that would be 65/32
Answer:
50.80 cm^3
Step-by-step explanation:
the polyhedron is a rectangular pyramid
Volume of a rectangular pyramid = 1/3 x ( width x height x length)
1/3 ( 4 x 5 x 3) = 20 inches
we need to convert inches to cm
1 in = 2.54 cm
20 x 2.54 = 50.80 cm^3
