The Secant of angle A is -5/4. a) What quadrants could angle A be in? b) Determine the measure(s) of angle A

Answers

Answer 1

Answer:

a) 2nd and 3rd quadrant

b) 143.13° and 36.87°

Step-by-step explanation:

Secant A = 1/cosecant A

sec A = 1/cosA

If Sec A = -5/4

Cos A = 1/(-5/4)

CosA  = -4/5

Since cos A is a negative values, hence the angle A will be in the 2nd and 3rd quadrant

b) If CosA  = -4/5

A = arccos(-0.8)

A = 143.13

A = 180 - 143.13

A = 36.87

Hence the measures of angle A are 143.13° and 36.87°

12 hours? Explain your reasoning.
Answer quick PLZZ no website

Answers

Answer:

5 rooms

Step-by-step explanation:

4 rooms = 9 hours

9 hours = 540 minutes

1 room = 540 ÷ 4 = 135 minutes

60 x 12 = 720 minutes (12 hours)

720 ÷ 135 = 5.33333

5.3333 estimated to nearest whole number = 5

Given sin y = -4/5, where π < y < 3π/2, and cos x = 12/13, where 0 < x < π/2. Find the exact value of sin (x - y).

Please show all the exact steps in order I am really lost on how to solve this.

Answers

Answer:

Solution given:

sin y = -4/5

p/h=4/5

p=4

h=5

b=√{5²-4²)=3

cos y = b/h=-3/5

again

cos x=12/13

b/h=12/13

b=12

h=13

p=√(13²-12²)=5

sin x=p/h=5/13

now

sin[x-y]=sinxcosy-cosxsiny

If f (-8)= 0 and f (x)= x^3-x^2-58x+112, find all the zeros of f(x) write your answer in ascending order

Answers

Answer:

The zeros in ascending order are 2, 7, 8.

Step-by-step explanation:

Since f(-8) = 0, it means that (x + 8) is a factor of the function f(x)= x³ - x² - 58x + 112.

I have attached the long division of this to get the remaining factors of the polynomial function.

The remaining factor is;

x² - 9x + 14

Using quadratic formula via a calculator, we have; x = 7 and x = 2

Thus,the zeros of the polynomial function f(x)= x³ - x² - 58x + 112 in ascending order are;

2, 7, 8

Answers

Answer: 34 books

Step-by-step explanation:

Since Erik read a total of 4 books over 2 months. This means that every month, he read (4/2) = 2 books.

After belonging to the book club for 17 months, the number of books that he'll have read will be the number of books he read per month multiplied by 17 months. This will be:

= 2 × 17

= 34 books
