mid point formula
Answer:
2 real solutions
Step-by-step explanation:
To determine the nature of the solutions use the discriminant
Δ = b² - 4ac
• If b² - 4ac > 0 then 2 real solutions
• If b² - 4ac = 0 the 2 real and equal solutions
• If b² - 4ac < 0 then no real solutions
Given
x² + 9x + 20 = 0 ← in standard form
with a = 1, b = 9, c = 20, then
b² - 4ac
= 9² - (4 × 1 × 20 ) = 81 - 80 = 1
Since b² - 4ac > 0 then there are 2 real solutions
Answer: If you want to make more cookies then what is called for in this situation then you would need <u><em>6 cups of milk.</em></u>
Step-by-step explanation: You have 2 cups of milk and 3 cups of flour of course. In order to make a complete batch you need 2 cups of milk and 3 cups of flour. In order to make a second batch you need the same things as you did for the first batch. Therefore two batches of cookies requires 4 cups of milk and 6 cups of flour. In this situation you want to make 3 batches of cookies. The required items are <u><em>6 cups of milk</em></u> and 9 cups of flour.
Answer:
After 30 hours Plan B will be more profitable than Plan A
Step-by-step explanation:
Plan A. $300 + 65(30) = 2250
Plan B. $75(30) = 2250
Afterwards . . . Plan A. $300 + 65(31) = 2315
Plan B. $75(31) = 2325
You're welcome!
