Answer:

36 <127

(36,127°)

36 [ cos (127) + i sin (127)]

Step-by-step explanation:

w1 = 2 < 95

w2 = 18 < 32

w1 * w2

We multiply the magnitude and add the angles

w1 * w2 = 2*18 < (95+32)

=36 < 127

36 [ cos (127) + i sin (127)]

Based on a kc value of 0.210 and the data table given, what are the equilibrium concentrations of xy, x, and y, respectively?

a_sh-v [17]

The activation energy for the forward and the one for the reverse reaction are similar because they attained chemical equilibrium. A chemical equilibrium happens when both of the reactant and products achieve the same concentration.

39 3.3 5.1 3.3 x find the value in the triangle shown below

prohojiy [21]

9514 1404 393

Answer:

x = 102

Step-by-step explanation:

Isosceles triangles have equal angles opposite equal sides. There are two 39° angles in this triangle (opposite the 3.3 sides), so the third one is ...

x° = 180° -2(39°)

x° = 102°

_____

<em>Additional comment</em>

The triangle is "overspecified", meaning more measures are provided than are necessary to completely describe the triangle. As is often the case in such situations, the measures provided are sufficiently inconsistent that two different "right" answers are possible, depending on how you work the problem. The first attachment shows the solution above.

The second attachment shows the solution you might get by using the Law of Cosines. Note that x=101 in this case.

Find the sum of <br> -6 1/8+1 1/4

Vlad [161]

Answer:

$\large\boxed{-4\dfrac{7}{8}=-4.875}$

Step-by-step explanation:

To add two fractions, they must have the same denominator.

LCD = 8

$1\dfrac{1}{4}=1\dfrac{1\cdot2}{4\cdot2}=1\dfrac{2}{8}$

$-6\dfrac{1}{8}+1\dfrac{1}{4}=-6\dfrac{1}{8}+1\dfrac{2}{8}=-\left(6\dfrac{1}{8}-1\dfrac{2}{8}\right)=(*)\\\\\text{We know}\ 1=\dfrac{8}{8},\ 6=5+1=5+\dfrac{8}{8}=5\dfrac{8}{8}.\\\\\text{Therefore}\ 6\dfrac{1}{8}=5\dfrac{8+1}{8}=5\dfrac{9}{8}\\\\(*)=-\left(5\dfrac{9}{8}-1\dfrac{2}{8}\right)=-\bigg((5-1)+\dfrac{9-2}{8}\bigg)=-\bigg(4+\dfrac{7}{8}\bigg)=-4\dfrac{7}{8}$

You can convert the fractions to the decimals.

$6\dfrac{1}{8}=8.125\\\\1\dfrac{1}{4}=1.25\\\\-6\dfrac{1}{8}+1\dfrac{1}{4}=-6.125+1.25=1.25-6.125=-4.875$
