Question

Which estimate best describes the area under the curve in square units?

10 units²

15 units²

30 units²

35 units²

Answer 1

The best estimate that describes the area under the curve in square units is 15 units². To calculate the area, we find the area of the right triangle formed by the curve and x-axis.

Step-by-step explanation:

The best estimate that describes the area under the curve in square units is 15 units². To calculate the area under the curve, we can find the area of the right triangle formed by the curve and the x-axis. In this case, the base of the triangle is 5 units and the height is 3 units. Multiplying base and height and dividing by 2, we get an area of 7.5 units². However, since the triangle is under the x-axis, we take the absolute value of the area, which is 15 units².

Answer 2

B) 15 units^2
each box equals 0.5 × 1 = 0.5 units^2, so add up how many boxes, and it's close to around 30, so 30×0.5 = 15 units^2
