the answer I got is 5.184
Answer:
12m - 4
☆ putting the value of m in the above formula
12 × 4 - 4
= 48 - 4
= 44
6r - 4
☆ Putting the value of r in the above formula
6 × 6 - 4
= 36 - 4
= 32
Answer:
Step-by-step explanation:
- There are 4 of them (acute angles that is)
- Those 4 are less than 90 degrees.
- They have supplementary angles which are greater than 90 degrees.
- There are 4 of them also.
- The total number of angles should be 8 if there are 2 parallel lines and 1 transversal.
The dot product is used to determine the magnitude of the resultant vector of two component vectors. It is expressed as a·b. It does not literally mean that you multiply their values. Instead, you multiply their matrices. However, since we cannot find matrices, let's just find the resultant vector through theorems involving triangles. By cosine law:
R = √[a² + b² - 2abcos(3π/4)]
R = √[60² + 30² - 2*60*30*cos(3π/4)]
R = 83.94
Thus, a·b = 83.94
4/3(pi)(radius)^3 is the volume formula for a sphere, so you can use that to find the volume. Hope that helped :D
