Answer: The value of sin∠A = 36.86°.

Step-by-step explanation:

Since we have given that

AB = 5 units

AC = 4 units

BC = 3 units

So, we need to find the sine ∠A.

As we know the formula for "Sine":

\sin A=\dfrac{Opposite}{Adjacent}\\\\\sin A=\dfrac{BC}{AB}\\\\\sin A=\dfrac{3}{5}\\\\\sin A=0.6\\\\A=\sin^{-1}((0.6)\\\\A=36.86^\circ

Hence, sin∠A = 36.86°.

Find the length of the missing side.
White raven [17]

Answer:

14.4 inches

Step-by-step explanation:

Use the Pythagorean theorem: a^{2} + b^{2}

So, this will be: 8^{2} + 12^{2} = c^{2}

By simplifying we get:

c = \sqrt{208}

The missing side is: 14.4 (rounded to the tenth)

1/5z -5/6 = -4/5z -1/3
sveta [45]

Answer:

z = 15/30 = 3/6

Step-by-step explanation:

1/5z - 5/6 = - 4/5z - 1/3

1/5z + 4/5z = - 1/3 + 5/6

5/5z = - 2/6 + 5/6

5/5z = 3/6

z = 3/6 / 5/5

z = 3/6 * 5/5

z = 15/30

What is this please help?
mestny [16]

Answer:

y = 2/3x - 1

Step-by-step explanation:

The simpliest way to determine the slope of the line is to see the rise over run of the line. In this case, we are given two points which are at (0, -1) and (3,1)

By calculating rise of run, we can see that the starting point goes up by 2 units, from -1 to 1 and goes to the right 3 units, from 0 to 3

In this case, that means we have a slope of 2/3x.

The +b plays into the y-intercept of the line, which is actually the same of one of our points: (0,-1)

Since this number is a negative, it would actually be y = (2/3)x + (-1) which is the same as y=2/3x - 1

Answer:

Option Y is correct.

Step-by-step explanation:

We are given the table representing the relation between new students and returning students for difference classes.

It is required to form the relative frequency table for the given situation.

So, relative frequency table is obtained by dividing the valued by the total number of values in the data set.

<em>Thus, we will get the relative frequency table by dividing the given table values by 500.</em>

Hence, we will get the following table,

                          New Students               Returning Students           Total

10th                         0.01                                   0.34                             0.35

11th                          0.006                                0.324                           0.33

12th                         0.004                                0.316                            0.32

Total                        0.02                                  0.98                                1

Thus, option Y is correct.
