Answer:
x-intercept means the advertising expense when the company's profit was zero dollars ⇒ D
Step-by-step explanation:
Let us solve the question
∵ P = -250x³ + 1,505x² - 300, for 0 < x < 6
∵ P is the profit in tens of thousands of dollars
∵ x is the advertising expense in tens of thousands of dollars
∴ x is the independent variable
∴ P is the dependent variable
→ x-intercept means value x when P is 0
∵ The x-intercept is the value x at P = 0
∴ x-intercept means the advertising expense when the company's
profit was zero dollars

Without a calculator, choose the statement that best describes the value of√74.
Choose 1 answer:
A: the value of √74 is between 8 and 8.5
B: the value of √74 is between 8.5 and 9
C: the value of √74 is between 9 and 9.5
D the value of √74 is between 9.5 and 10
Answer:
B
Step-by-step explanation:
Well you can get rid of c and d since 9^2 = 81. so 74 is less than 81 so it's definitely less than 9. Now, we know it's between 8 and 9. try multiplying 8.5 x 8.5 = 72.25. So our ranges are
A) 64 - 72.25
B) 72.25 - 81.
74 falls between 72.25 - 81. So it'll be B
