Answer:

x = 13°

Step-by-step explanation:

Check the diagram attached below to see how the angles labelled A and B, which are interior angles of the triangle where x is found.

Let's find the measure of angle A and angle B.

m<A = 85° (vertical angles are congruent)

m<B = 180° - 98° = 82° (corresponding angles/supplementary angles)

Thus:

x + A + B = 180° (sum of interior angles of a ∆)

x + 85° + 82° = 180° (substitution)

x + 167 = 180

x = 180 - 167 (Subtraction property of equality)

x = 13°

The graph of a sinusoidal function has a max point (0,8) and min point (5,2) whats the formula
AleksandrR [38]

Answer:

                                                          π

The desired formula is    y = 3cos(----- t) +        5

                                                          5

Step-by-step explanation:

From maximum point  to minimum point, the change in x is  5 and the change in y (min to mx) is (8 - 2), or 6.  The graph repeats itself beginning at x = 6 and thus has period 10 (e. g., from first max to next max).

                                                                                         2π

Period and frequency are related through    period = ------

                                                                                            b

and so if the period is 10 (as it is here),

                            2π                                          2π         π

 period = 10 = ------------          Therefore, b = ------- = -------

                              b                                           10          5

                                                          π

The desired formula is    y = 3cos(----- t) +        5

                                                          5

3 is the amplitude and 5  is the vertical offset from y = 0.

similarly for faculty  members  ways (8,3)       and  for students C (20,5)

the number of possible committee = 4!/2!2!  ×  8!/3!5!   ×20!/5!15!

                                                          = 6  ×56 ×15504

                                                          = 5,209,344

A college football stadium has a capacity of 100,000 people. The team is sponsoring a family day when tickets are $50 per person
Keith_Richards [23]

Answer:

I believe the variable N would be 100,000 because it is saying that tickets are $50 a person so you have to multiply that by how many people are at the stadium. So you would do 50(100,000) which equals 5,000,000.

Step-by-step explanation:

Explanation is in the answer above.
