Use the left-hand rule to estimate the area under the graph of y = (x + 1)2 – 1 for values of x from 0 to 3.

11 square units

Step-by-step explanation:

Using the left-hand rule to estimate the area under a graph y = f(x) between the interval x = a to x = b is given by

.......... (1)

{Where n is the number of rectangles we want to make the area under curve.}

Now, in out case a = 0 and b = 3 and ....... (2)

Let us assume that  n = 3, then there will be 3 rectangles.

Therefore, from the equation (1), we can write

⇒ = 11 square units

{Since we have from equation (2), f(0) = 0, f(1) = 3 and f(2) = 8} (Answer)

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

answer: you need the equation in the question so i can answer it
