find the exact atea under y=x^2 on the interval [0,2] by using an infinite number of circumscribed rectangles. (Hint: 1^2 + 2^2

sergeinik [125]

Answer: $\bold{\dfrac{8}{3}}$

Step-by-step explanation:

$\int\limits^2_0 {x^2} \, dx =\dfrac{x^3}{3}\bigg|^2_0=\bigg(\dfrac{2^3}{3}\bigg)-\bigg(\dfrac{0^3}{3}\bigg)=\dfrac{8}{3}-0=\dfrac{8}{3}$

NOTE: Neither the Trapezoidal Rule or Reimann Sums can be used without the number of rectangles (n) you are separating the interval into. Besides, they only provide an estimate. If you want the EXACT area, you must use integration.

On the graph of the equation 5x - y = 8, the point whose y-coordinate is 7 has an x-coordinates of ?

Lemur [1.5K]

Answer:

x = 3

Step-by-step explanation:

To find the x-coordinate, substitute y = 8 into the equation abd solve for x

5x - 7 = 8 ( add 7 to both sides )

5x = 15 ( divide both sides by 5 )

x = 3

Thus (3, 7) is a solution to the equation
