Let's find the discriminant of <span>x^2+9x+14=0. Here, a=1, b=9 and c=14.
The discriminant is b^2-4ac. Substituting the above numeric values,
9^2-4(1)(14) = 81-56 = 25
The sqrt of 25 is 5. Thus, your polynomial has two unequal, real roots.
Off the point example: If the discriminant were zero, your poly would have two real, equal roots.</span>

Answer:
A. 4.8 units
Step-by-step explanation:
Segment ZX can divide the figure into two right triangles. Then angle XZY is 136°/2 = 68°. The tangent relation tells you ...
Tan = Opposite/Adjacent
tan(68°) = XY/r
r = 12/tan(68°) ≈ 4.848 ≈ 4.8
The radius of the circle is about 4.8 units.
Answer:
<u>60 people per square mile</u>
Step-by-step explanation:
<u>Given</u> :
- Population of Mississippi = 2,844,658
- Area of Mississippi = 47,691 square miles
- Population density is the rough calculation of people (population) per square mile
<u>Population Density</u>
- Population / No. of square miles
- 2,844,658 / 47,691
- ⇒ 59.6476903 (approx.)
- ⇒ <u>60 people per square mile</u>
