answer is below
Step-by-step explanation:
A) The function that can be used to get the total
profit is; f(x) = 18x - 900
Answer:
No
Step-by-step explanation:
It will be a right triangle if it follows Pyhthagoras Theorem . Where the sum of squares of two smaller sides is equal to the square of the 3rd side. Let's check ,
→ 11²+ 12² = 13²
→ 121 + 144 = 169
→ 265 ≠ 169
<h3>Hence the ∆ is not a right angled triangle </h3>
Answer:
9 and -2
Step-by-step explanation:
9 - 2 = 7
9 * -2 = -18
Answer:
See explanation
Step-by-step explanation:
The discriminant is
1. 9² - 4(1)(20) = 81 - 80 = 1 so there are 2 solutions
2. (-9)² - 4(3)(-13) = 81 + 156 = 237, so there are 2 solutions
3. The first answer is correct
