cos x= 3/4, s in quadrant 1

Answers

Answer: x = 41.4°

Step-by-step explanation:

We want to solve:

Cos(x) = 3/4

Such that this is on quadrant 1.

(if x is in degrees, the possible values of x will be: 0° ≤ x ≤ 90°)

To solve this we need to remember the inverse functions.

If we have two functions f(x) and g(x), these functions are inverses if:

f( g(x) ) = x

g( f(x) ) = x

Then the inverse of the cosine function (this function is "arcos(x)") is such that:

Arcos( cos(x) ) = x

Then in our equation:

Cos(x) = 3/4

We can apply the inverse function to both sides to get:

Arcos(Cos(x)) = Arcos(3/4)

x = Arcos(3/4)

(To find the Arcos function in your calculator, you need to use the button "inv" and then the "cos" button, and remember to have your calculator in deg mode)

x = Arcos(3/4) = 41.4°

(C) The sum of the measures of ∠P, ∠Q, and ∠R is 180°

Step-by-step explanation:

All triangles, when their three angles are added up, gets us 180°.

This goes without saying, even with scalene triangles.

Additionally, the angles in squares add up to 360°, the angles in a pentagon add up to 540°.

The point (–3, –5) is on the graph of a function. Which equation must be true regarding the function?
a. f(–3) = –5
b. f(–3, –5) = –8
c. f(–5) = –3
d. f(–5, –3) = –2

Answers

Answer:

a. f(–3) = –5

Step-by-step explanation:

On a graph,  point (x, y) can be also represented as function f (x) = y

it means that if f(x) has input value as x then its output value will be y.

Now given that  in the problem that

The point (–3, –5) lies on the graph

it means that for function  input value of of -3 has the  out put value of  -5

which can also be written as

f(-3) = -5

Hence the correct choice is a. f(–3) = –5.

which of the following is not an empty set? A. {vowels in the word rhythm} B. {day in a week that starts with the letter J} C. {bicycle with four wheels} D. {soldiers in the philippines}​

Answers

Answer:

B. {day in a week that starts with the letter J}

Step-by-step explanation:

In the given situation if we go option B that the day in the week started from the letter J

So if we write the total days in a week i.e.

Monday, Tuesday, wednesday, thursday and friday

Now as we can see that there is no day in a week started with J letter

So the option b is correct

What is the decimal 0.84 (84 repeating) as a fraction? Help pretty please

Answers

Answer:

28/33

Step-by-step explanation:

We first let 0.84 be  x.

Since  x  is recurring in 2 decimal places, we multiply it by 100.

100x=84.84

Next, we subtract them.

100x−x=84.84−0.84

99x=84

Lastly, we divide both sides by 99 to get  x  as a fraction.

x=84/99

=28/33
