3 0

Answer:

-11/20

Step-by-step explanation:

    2      8   1

 (0-— ÷ (0-—))+—

    3      9   5

           8

Simplify   —

           8/9

2         8     1

 (0 -  — ÷ (0 -  —)) + —

       3         9     5

Simplify   —

           2/3

2   -8     1

 (0 -  — ÷ ——) +  —

       3   9      5

2      -8

Divide  —  by  ——

        3      9

To divide fractions, write the divison as multiplication by the reciprocal of the divisor :

2     -8       2      9

—  ÷  ——   =   —  •  ——

3     9        3     -8

(0--3/4)+1/5

Least Common Multiple:

     20

Left_M = L.C.M / L_Deno = 5

Right_M = L.C.M / R_Deno = 4

      3 • 5 + 4                 -11

—————————  =  ———

      20                            20

-11/20

Given sin theta= 6/11 and sec theta < 0, find cos theta and tan theta.
bekas [8.4K]

Answer: option a.

Step-by-step explanation:

By definition, we know that:

cos^2(\theta)=1-sen^2(\theta)\\\\tan(\theta)=\frac{sin(\theta)}{cos(\theta)}

Substitute sin(\theta)=\frac{6}{11} into the first equation, solve for the cosine and simplify. Then, you obtain:

cos(\theta)=\±\sqrt{1-(\frac{6}{11})^2}\\\\cos(\theta)=\±\sqrt{\frac{85}{121}}\\\\ cos(\theta)=\±\frac{\sqrt{85}}{11}

As sec\theta then cos\theta:

cos(\theta)=-\frac{\sqrt{85}}{11}

Now we can find tan\theta:

tan\theta=\frac{\frac{6}{11}}{-\frac{\sqrt{85}}{11}}\\\\tan\theta=-\frac{6\sqrt{85}}{85}

Determine whether the vectors u and v are parallel, orthogonal, or neither. u = (5,4) v = (-10,9)
12345 [234]

Answer:

Neither

Step-by-step explanation:

5 x -10 = -50

4 x 9 = 36

-50 + 36 = -14 and therefore can not be orthogonal

sqrt(25+16)=sqrt(41)

sqrt(100+81)=sqrt(181)

sqrt(41) x sqrt(181) is not equal to -14 so therefore it is not parallel

So the answer is then neither

Which of the following verifies that AABC is similar to A DEF?
emmainna [20.7K]

Answer:

D

Step-by-step explanation:

According to the SAS theorem, if the 2 sides of the 2 triangles are multiples of each other by the same scale factor, with the angle in between them being the same for each triangle. The triangles are similar.

The SSS theorem is not appropriate here because we do not know the side lengths of AB or DE in the diagram. For SSS theorem we need to know all of the side lengths.

A is incorrect because the similarity can be determined.
