Area = 1/2 * base * height
= 1/2 * 20 * 6
= 1/2 * 120
= 60 ft^2
Answer:
The function increasing ⇒ 3 ≤ x ≤ 6 answer C
Step-by-step explanation:
∵ The vertex of the parabola is (3 , -6)
∴ The minimum value = -6 at x = 3
∵ The left part of the parabola is decreasing because the value of y decreased from 3 to -6 when 0 ≤ x ≤ 3
∵ The right part of the parabola is increasing because the value of y increased from -6 to 3 when 3 ≤ x ≤ 6
∴ The function is increasing at interval 3 ≤ x ≤ 6
Answer:
b) -6x - 3
Step-by-step explanation:
3(-2x-1)=3*(-2x)+3*(-1)= -6x - 3
