Answer:
1/27 in ^3
Step-by-step explanation:
where length - 1/3 inches
width - 1/3 inches
height - 1/3 inches
the formula to find volume is as follows
volume =
numerators should be multiplied by numerators and denominators by denominators
volume =
volume of the cube is 1/27 in.³
We are to verify the identity:
cos(α-B)-cos(α+B) = 2 sinα sinβ
Left hand side = cos(α - B)-cos(α + B)
= cosα cosβ + sinα sinB - (cosα cosB - sinα sinβ)
= cosα cosβ + sinα sinB - cosα cosB + sinα sinβ)
= sinα sinβ + sinα sinβ
= 2 sinα sinβ
= Right Hand side
An example of a ratio would be:
1:2
3:4
5:6
An example of a proportion would be:
1/2
3/4
5/6
