<u>Answer</u>

-5/3, -1, 0.7, √2, √5

<u>Explanation</u>

√5 = 2.236

-1 ⇒ this is less than 1.

-5/3 = -1.666667 this is less than 1. -5/3 < -1

0.7 > -1

√2 = 1.414 ⇒ √5 > √2

Arranging them from the least to the greatest;

-5/3, -1, 0.7, √2, √5

Answer:

Answer is $\frac{4}{3}$

Step-by-step explanation:

To find the interval of x. Use our equations to equal each other.

$-x^2+2x=y,y=0$

$-x^2+2x=0\\-x(x-2)=0\\-x=0 , (x-2)=0\\x=0 ,2$

$\int\limits^2_0 {-x^2+2x} \, dx$

Integrate.

$\frac{-x^3}{3}+x^2\\(\frac{-2^3}{3}+2^2)-[\frac{-0^3}{3}+0^2]\\-\frac{8}{3} +4-0\\-\frac{8}{3}+\frac{12}{3} =4/3$

Using Desmos I have Graphs of both of the equations you have provided. The problem asks us to find the shaded region between those curves/equations.

Proof Check your interval of x.
