Answer: B. A cube with side lengths of 4 feet has a volume of 64 cubic feet.
Step-by-step explanation:
The input is 4, so we are talking about a cube with a side length of 4 feet.
The output is the volume, so we know the volume is 64 cubic feet.
Nah they make night lamps for lizards that is basically a black light but still puts off heat
For the right triangle shown in the picture, recall the trigonometric identity of the cosine function:
![\cos (B)=\frac{a}{c}](https://tex.z-dn.net/?f=%5Ccos%20%28B%29%3D%5Cfrac%7Ba%7D%7Bc%7D)
Isolate <em>a</em> from the equation:
![a=c\cdot\cos (B)](https://tex.z-dn.net/?f=a%3Dc%5Ccdot%5Ccos%20%28B%29)
Substitute for <em>c=6.3</em> and <em>B=43.8°</em>:
![a=6.3\cos (43.8)](https://tex.z-dn.net/?f=a%3D6.3%5Ccos%20%2843.8%29)
