Answer:
The minimum value = -38
Step-by-step explanation:
∵ f(x) = x² - 12x - 2
∵ -12x ÷ 2 = -6x ⇒ -6 × x
∴ (x - 6)² = x² - 12x + 36
∴ Add and subtract 36 in f(x)
∴ f(x) = (x² - 12x + 36) - 36 - 2
∴ f(x) = (x - 6)² - 38 ⇒ completing square
∴ The vertex of the parabola is (6 , -38)
∵ Its minimum point because the coefficient of x² is positive
∴ The minimum value = -38
Answer:
Triangular prism
Step-by-step explanation:
Answer:f(t)=4/9t — 12
Step-by-step explanation:
1. 4 is being multiplied by t first then divided by 9 not by 4/9 so there shouldn’t be any parentheses.
2. 12 is being subtracted from this so it should be 4/9t—12.
3. Final answer: f(t)= 4/9t — 12
Answer:
2
the answer is 2 coz it's like terms
Answer:
12 should be 41
Step-by-step explanation:
12) the pattern is an increase by 5 each time. This would mean the 8th term is 40. However, it starts at 1, so you should add 1 to this answer, making it 41. This pattern is y=5x+1 if x is that number in the pattern and y is the answer.
