Answer:

This term would not change at all when combining like terms.

Step-by-step explanation:

Because the first term has a variable and the second does not, they can not be combined. Therefore, there is not change to this assignment

ABCD is a quadrilateral work out CD

Paladinen [302]

In a quadrilateral ABCD, the measure of the length of the quadrilateral CD will be 25.98 cm.

<h3>What is trigonometry?</h3>

The connection between the lengths and angles of a triangular shape is the subject of trigonometry.

The length of AD will be

tan θ = AB/AD

AD = 12/ tan 35

AD = 17.14 cm

Then the value of the BD will be given by the Pythagoras.

BD² = AB² + AD²

BD² = 12² + 17.14²

BD² = 144 + 239.78

BD² = 437.78

BD = 20.92 cm

Then operate the sine rule in triangle BCD, we have

$\dfrac{BD}{\sin C} = \dfrac{CD }{\sin B}\\\\\\\dfrac{20.92}{\sin 52} = \dfrac{CD }{\sin 102}\\\\\\CD = \dfrac{20.92 \times \sin 102}{\sin 52}$

On further solving, the value of CD will be

CD = 25.98

A recent article in the paper claims that business ethics are at an all-time low. Reporting on a recent sample, the paper clai

Savatey [412]

Answer:

P=0.3726 or 37.26%

Step-by-step explanation:

The success, with 41% of probability of occurring, is that the employee believes the company's president possesses low ethical standards. For more than 8 and less than 12 successes, it means the probability of having 9, 10 or 11 successes (all these summed).

The formula is:

$b(x;n,p)= \ _nC_x*p^x*(1-p)^{n-x}$

Where x is the number of successes,n the number of trials, p the probability of success, $_nC_x$ refers to the combinations that can occur, and it's formula is:

$_nC_x=\frac{n!}{x!(n-x)!}$

Calculating each case:

$b(9,20,0.41)=\frac{20!}{9!(20-9)!}*0.41^9*(1-0.41)^{20-9}=0.1658$

$b(10,20,0.41)=\frac{20!}{10!(20-10)!}*0.41^{10}*(1-0.41)^{20-10}=0.1267$

$b(11,20,0.41)=\frac{20!}{11!(20-11)!}*0.41^{11}*(1-0.41)^{20-11}=0.0801$

Adding each case:

$P=0.1658+0.1267+0.0801= 0.3726$

A fluid has density 810 kg/m3 and flows with velocity v = z i + y2 j + x2 k, where x, y, and z are measured in meters and the co

mixas84 [53]

Denote the cylindrical surface by $S$ , and its interior by $R$ . By the divergence theorem, the integral of $\vec v$ across $S$ (the outward flow of the fluid) is equal to the integral of the divergence of $\vec v$ over the space it contains, $R$ :

$\displaystyle\iint_S\vec v\cdot\mathrm d\vec S=\iiint_R(\nabla\cdot\vec v)\,\mathrm dV$

The given velocity vector has divergence

$\vec v=z\,\vec\imath+y^2\,\vec\jmath+x^2\,\vec k\implies\nabla\cdot\vec v=\dfrac{\partial(z)}{\partial x}+\dfrac{\partial(y^2)}{\partial y}+\dfrac{\partial(x^2)}{\partial z}=2y$
