Answer:
a. n² +10n +25 = 0
b. 0
c. 1 real solution
Step-by-step explanation:
a. Add 25 to put the equation in standard form.
n² +10n +25 = 0
__
b. The discriminant is d = b²-4ac.
d = 10² -4(1)(25) = 0
The discriminant is 0.
__
c. A discriminant of 0 means there is 1 real solution.
Answer:
d ≈ 14.6 units; M (2.5, 2, 6)
Step-by-step explanation:
Using the distance formula for 3-D dimensions, you get the √(213) which equals 14.6
Then, using the midpoint formula for 3-D dimensions, you find the coordinates 2.5 for x, 2 for y, and 6 for z.
