-√12 + 3√3

Rewrite √12 as 2√3

-2√3 + 3√3

Just add the numbers before the radical.

-2 + 3 = 1

1√3 = √3

<h3>The simplified form of the provided expression is √3 or 1.73</h3>

$(13^4 - 11^4)(13^2+11^2)$

add all together with exponents

=48*290

= Then turn into a smaller exponent

= $2^4 * 3 * 2*145$

combine like terms

Find the average value of the function on the given interval.<br> f(x)=2 ln x; [1,e]

JulijaS [17]

Answer:

$f_{avg}=\frac{1}{e-1}$

Step-by-step explanation:

We are given that a function

$f(x)=2lnx$

We have to find the average value of function on the given interval [1,e]

Average value of function on interval [a,b] is given by

$\frac{1}{b-a}\int_{a}^{b}f(x)dx$

Using the formula

$f_{avg}=\frac{1}{e-1}\int_{1}^{e}lnx dx$

By Parts integration formula

$\int(uv)dx=u\int vdx-\int(\frac{du}{dx}\int vdx)dx$

u=ln x and v=dx

Apply by parts integration

$f_{avg}=\frac{1}{e-1}([xlnx]^{e}_{1}-\int_{1}^{e}(\frac{1}{x}\times xdx))$

$f_{avg}=\frac{1}{e-1}(elne-ln1-[x]^{e}_{1})$

$f_{avg}=\frac{1}{e-1}(e-0-e+1)=\frac{1}{e-1}$

By using property lne=1,ln 1=0

$f_{avg}=\frac{1}{e-1}$

vovangra [49]

Answer:

X = 70, y = 21

Step-by-step explanation:

53 + 6y + 1 = 6y + 54

6y + 54 = 180

180 - 54 = 126

6y = 126

126 ÷ 6 = 21

Y = 21

21 × 6 + 1 = 127

127 = 2x - 13

127 + 13 = 140

140 ÷ 2 = 70

X = 70

Opposite angles are congruent and consecutive angles are supplementary.
