Answer:
101 Songs
Step-by-step explanation:
At 100 songs, both service will equal the same amount:
NEW SERVICE- 15+0.8(100)= $95.00
OLD SERVICE- 0.95(100)= $95.00
After 1 more song the new service becomes less expensive:
NEW- 15+0.8(101)=$95.80
OLD- 0.95(101)=$95.95
how is the volume of a solution used in calculating concentration?
Answer:
No real roots
Step-by-step explanation:
Given
7x² + 5x + 1 = 0 ← in standard form
with a = 7, b = 5, c = 1
To determine the nature of the roots use the discriminant
Δ = b² - 4ac
• If b² - 4ac > 0 then roots are real and distinct
• If b² - 4ac = 0 then roots are real and equal
• If b² - 4ac < 0 then the roots are not real
Here
b² - 4ac = 5² - (4 × 7 × 1) = 25 - 28 = - 3
Thus the 2 roots are not real
