Answer:
a. -216, 0 real roots
Step-by-step explanation:
The discriminant of ...
ax² + bx + c = 0
is ...
d = b² -4ac
When we put your equation into the standard form shown above, we get ...
7n² +8n +10 = 0
Then we can identify a=7, b=8, c=10. The discriminant is then ...
d = 8² - 4·7·10 = 64 -280 = -216
___
The interpretation of the discriminant is ...
- < 0; no real roots (2 complex roots)
- = 0; one real root (multiplicity 2)
- > 0; 2 real roots
Your discriminant is -216, so there are 0 real roots.

Square root is always dividing by a whole factor :)
Answer:
Hey there!
Velocity is a vector, not a scalar because it also has direction.
Let me know if this helps :)
Related to ur last question......food totaled 17.42
17.42 - 1.75 = 15.67...this is with the coupon added
15.67 + 0.87 = 16.54....this is the final total....with tax included

Answer:
Subjective
Conditional
Step-by-step explanation:
The 0% probability of accepting the offer is a subjective probability, since it is derived from candidate 4's individual personal judgment without calculations.
As for the 100%, it is a conditional probability, since it is linked to the probability of another event also happening. It is that probability of candidate 4 accepting the offer, given that candidate 5 is also hired.
