Answer:

Step-by-step explanation:

Givens

4 sides = 4*p

3 sides = 3(4p) = 12p

Other sides

Total length = 138 inches

Equation

4p + 12p + 10 + 12 + 4 = 138

Solution

Collect like terms

16p + 26 = 138

Subtract 26 from both sides

16p + 26 - 26 = 138 - 26

16p = 112

Divide by 16

16p/16 = 112/16

p = 7

Longest Side (Answer)

7 * 4 = 28 inches

Answer:

x = 0

Step-by-step explanation:

3(x - 1) = 2x - 3 + 3x

3x - 3 = 2x - 3 + 3x

0 - 3 = 2x - 3

0 = 2x

2x = 0

x = 0 ÷ 2

x = 0

∫c x sin y ds, C is the line segment from (0, 1) to (3, 5)

Mnenie [13.5K]

Parameterize the line segment $C$ by

$\mathbf r(t)=\langle x(t),y(t)\rangle=(1-t)\langle0,1\rangle+t\langle3,5\rangle=\langle3t,1+4t\rangle$

where $t\in[0,1]$ . Then

$\mathrm ds=\|\mathbf r'(t)\|\,\mathrm dt$
$\mathrm ds=\|\langle3,4\rangle\|\,\mathrm dt$
$\mathrm ds=5\,\mathrm dt$

So the integral is

$\displaystyle\int_Cx\sin y\,\mathrm ds=5\int_0^1x(t)\sin y(t)\,\mathrm dt$
$=\displaystyle5\int_0^13t\sin(1+4t)\,\mathrm dt$
$=\dfrac{15}{16}(\sin5-\sin-4\cos5)\approx-2.7516$

Given

Balthazar,Rudy,Jebediah and Ezekiel in a single-File line to pull sleigh

Jebediah and Ezekiel Stay together

i.e. we need to arrange three person considering Ezekiel and jebediah as Single person

therefore 3 person can be arrange in 3! ways =6

and also Ezekiel and Jebediah can be arranged in 2 ways

Therefore a total of $2\times 6$ ways are possible

Answer:

The number of solutions of the system is 0

Step-by-step explanation:

we know that

When solving a system of equations by graphing, the solution of the system is equal to the intersection point both graphs.

In this problem the graphs do not intersect

therefore

The number of solutions of the system is 0
