Answers
Answer:
[tex]\cos^{-1}( \cos 43^{\circ}) = 43^{\circ}[/tex]
Step-by-step explanation:
The correct answer of the given function [tex]cos^{-1}[/tex] (cos 43°) will be 43°.
What is a trigonometric function?The fundamental 6 functions of trigonometry have a range of numbers as their result and a domain input value that is the angle of a right triangle.
It will be possible to comprehend the graphs, domains, differentiation, and integration of the four quadrants' trigonometric functions.
The trigonometric function is only valid for the right angle triangle and it is 6 functions which are given as sin cos tan cosec sec cot.
We know that the inverse trigonometric function of any function will vanish.
[tex]cos^{-1}[/tex] (cos 43°) = 43° cos inverse has vanished with cos and thus 43° is coming out to be the answer.

The number of more hours spent on baseball than volleyball is 3 hours. The correct option is B:3
Calculating time spent on sportFrom the question, we are to determine how many hours Elsa played baseball than volleyball
From the given information,
Elsa played sports for 20 hours
From the circle graph,
She spent 25% of the time on baseball
Time spent on baseball = 25% × 20 hours
Time spent on baseball = (25/100) × 20 hours
Time spent on baseball = 0.25 × 20 hours
Time spent on baseball = 5 hours
For time spent on volleyball
From the circle graph, she spent 10% of the total time on volleyball
Time spent on volleyball = 10% × 20 hours
Time spent on volleyball= (10/100) × 20 hours
Time spent on volleyball= 0.1 × 20 hours
Time spent on volleyball= 2 hours
The number of more hours spent on baseball than volleyball
= 5hours - 2 hours
The number of more hours spent on baseball than volleyball = 3 hours
Hence, the number of more hours spent on baseball than volleyball is 3 hours. The correct option is B:3

What is trigonometry?Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
Let's suppose the distance between the Lisa and Penny is x feet.
We can draw a right-angle triangle for this situation.
As we can see in the right angle triangle.
tan54.5 = x/50 (from the right-angle triangle)
x = 50tan54.5
x = 70.09 ≈ 70.1 feet
Thus, the straight-line distance between penny and Lisa is 70.1 feet if Lisa is laying on a towel at the beach, which is 50 feet from the base of the hotel.

Pam earns x dollars, Ryan earns (x+60) dollars and Rufus earns (x - 10) dollars. Together they earn a total of 530 dollars.
a) Calculate the value of x
b) the amount Ryan earns.
Answers
Answer:
A) 160 B) 220
Step-by-step explanation:
Combine like terms.
3x + 50 = 530.
Subtract 50 from both sides.
3x = 480.
Divide both sides by 3.
x = 160.
Since Ryan earns x + 60, add 60.
160 + 60 = 220.
What two operations would you use to solve the equation 3/4m - 6 = 12
-multiplication
-division
-addition
-subtraction
Answers
To solve this expression, we can use the mathematical operations: addition, multiplication and division. So the correct value, will be m = 1/24
This expression is an equation of the first fractional degree. To calculate, let's:
— move the negative - term to the other side of the positive equation, thus adding:
3/4m - 6 = 12
3/4m = 12 + 6
3/4m = 18
— Now, let's calculate without being fractional. We will isolate the variable multiply the terms with each other:
3/4m = 18
3 = 4m . 18
3 = 72m
— Finally, we'll turn this equation into a fraction, like this - simplifying the numerator and denominator by the same real number:
3 = 72m
m = 3/72
m = 3÷3 / 72÷3
m = 1/24
Therefore, the correct value of this expression is m = 1/24
