Quadratic formula: (-b +/- sqrt(b^2 - 4ac)) / 2a
a = 10
b = -1
c = 9
1 +/- sqrt((-1)^2 - 4(10)(9)) / 2(10)
1 +/- sqrt(1 - 360) / 20
x = 1 +/- sqrt(359i) / 20
Hope this helps!

Answer:From the attached graphic, Half-life = ln (.5) / k
Half-life =.693147 / 0.1142
= 6.0695884413 days
Step-by-step explanation:The value of "k" should be negative and should have units associated with it.
Answer: C) exactly one triangle
<u>Step-by-step explanation:</u>
Given: ∠A = 45°, ∠B = 65°, side c = 4 cm
By the Triangle Sum Theorem, ∠C = 70°
Now you have a proportion so you can use the Law of Sines to find the exact length of side a and of side b.

Thus, there is exactly one triangle.
Answer:
each time the numbers are being multiplied by 10
Step-by-step explanation:
1 × 10 = 10
10 × 10 = 100
100 × 10 = 1,000
