Answer:
Step-by-step explanation:
No because √2 and 3i come in pairs. The four roots are ±√2, 3i and -3i. The 5 guarantees that there are at least 5 roots to this equation. This is a good question to know the answer to. It looks like something that could be put on a test.
Answer:
Its the domain of real numbers Written diferently ( R ) or in interval notation ( ( ( −∞, +∞ )
Step-by-step explanation:
Answer:
A. 6x + 4
B. 22 cm
Step-by-step explanation:
The perimeter of the triangle is equal to the sum of all the side lengths, which is (2x+3) + (x+1) + (3x), or 6x + 4.
When x = 3cm, the perimeter is 6(3) + 4, which is 22 cm.
Answer:
10^-3
Step-by-step explanation:
Answer:
C. 7790.83 cm^3
Step-by-step explanation:
The volume of a sphere is given by
V = 4/3 pi r^3
We know the radius is 12.3
Using 3.14 for pi (This will give us an approximation, not an exact value)
V = 4/3(3.14) (12.3)^3
=7790.82984 cm^3
