To find the perimeter add up all the sides

There are 5 sides

3x+ 5+ 2x+2x+5

Combine like terms

3x+2x+2x +5+5

7x + 10

The perimeter is 7x+10 cm

Please help me struggling

Liula [17]

Answer:

Step-by-step explanation:

find the composition of g(x)=x−1 and h(x)= $\sqrt{x}$

hence we will get,

(g∘h)(x)=g(h(x))= g(x−1)= f(√x)= -1+√x = √x -1

Now to find f(g(h(x))),

f(x)=x4+6 and g(h(x))=√x -1

hence , putt g(h(x)) in f(x) ,

f(g(h(x)))= $(\sqrt{x}-1)^{4}$ +6 -

Evaluate triple integral ∫ ∫ ∫ 8xydV, where E lies under the plane z = 1+x+y and above the E region in the xy-plane bounded by t

vazorg [7]

Answer:

$\mathbf{=\dfrac{163.384}{15}}$

Step-by-step explanation:

$\int \int \limits_{E} \int \ 8 xy dV = \int\limits^{1}_{0} \int\limits^{\sqrt{x}}_{0} \int\limits^{1+x+y}_{0} \ 8xy dz dydx$

$= \int\limits^{1}_{0} \int\limits^{\sqrt{x}}_{0} [ 8xyz]^{z=1+x+y}_{z=0} \ \ dy dx$

$= \int\limits^{1}_{0} \int\limits^{\sqrt{x}}_{0} 8xy (1+x+y) dy dx$

$= \int\limits^{1}_{0} \int\limits^{\sqrt{x}}_{0} 8xy+8x^2y+8xy^2 \ \ dy dx$

$= \int\limits^{1}_{0} \ [ 4xy^2+4x^2y^2+2.7xy^3]^{ y= \sqrt{x}}_{y-0} \ \ dx$

$= \int\limits^{1}_{0} \ 4x (\sqrt{x})^2+4x^2(\sqrt{x})^2+2.7x(\sqrt{x})^3\ \ dx$

$= \int\limits^{1}_{0} \ 4x^2+4x^3+2.7x^{5/2} \ dx$

$\mathbf{=\dfrac{163.384}{15}}$
