Answer:

5x^2 - 7x - 10.

Step-by-step explanation:

11x^2+2-7x-6x^2-12

Bring like terms together We get:

11x^2 - 6x^2 - 7x + 2 - 12

= 5x^2 - 7x - 10.

What is the following quotient? StartFraction RootIndex 3 StartRoot 60 EndRoot Over RootIndex 3 StartRoot 20 EndRoot EndFraction

FrozenT [24]

Answer:

$\sqrt[3]{3}$

Step-by-step explanation:

We are required to simplify the quotient: $\dfrac{\sqrt[3]{60} }{\sqrt[3]{20}}$

Since the <u>numerator and denominator both have the same root index</u>, we can therefore say:

$\dfrac{\sqrt[3]{60} }{\sqrt[3]{20}} =\sqrt[3]{\dfrac{60} {20}}$

$=\sqrt[3]{3}$

The simplified form of the given quotient is $\sqrt[3]{3}$ .

Evaluate the upper and lower sums for f(x) = 2 + sin(x), 0 ≤ x ≤ π, with n = 2, 4, and 8. Illustrate with diagrams like the figu

larisa [96]

$f(x)=x+sin(x)\\ a=0\\ b=\pi \\ x_i=a+idelta(x)\\ Upper sum for n=2:\\ \\ delta(x)=\frac{b-a}{n} =\frac{\pi-0}{2} =\frac{\pi}{2}$

$x_0=0, x_1=\frac{\pi}{2} ,x_1=\pi \\$

Length of the subintervals: $[0,\frac{\pi}{2}], [\frac{\pi}{2}, \pi}]$

Using Upper Riemann sum,

$\int\limits^0_\pi{x+sin(x)\, dx =$ ∑Max{f(x_i) delta(x)

$=[max{(f(x_1))+max(f(x_2))]delta(x)\\ =(3+3)\frac{\pi}{2} \\=9.42$

Lower sum for n=2:

The minimum value for the function on $[0,\frac{\pi}{2}], [\frac{\pi}{2}, \pi]$ is 2.

$\int\limits^0_\pi {x+\sin x} \, dx =\sum_{n=0}^{n=2} min {f(x_i)} delta (x)\\$

$= (2+2)\frac{\pi}{2}\\ =6.28$
