The inverse of this trigonometric function is y = arccosx. Then the correct answer is option D.

The trigonometric functions in mathematics are real functions that connect the right-angled triangle's angle to the ratios of its two side lengths.

The given graph is represented by the function y = cosx. The inverse function will be y = arccosx.

Hence, the correct answer is option D.

Answer:

4. 120

5. 20

6. 55

Step-by-step explanation:

All straight lines have a degree of 180, so the angle measures all have to add up to 180 degrees.

Answer:

4) 120°

5) 20°

6) 55°

Step-by-step explanation:

4) 180°-60°=120°

5) 180°-160°=20°

6) 90°+35 = 125°

   180°-125°=55°

Answer:

61, C

Step-by-step explanation:

So, congruent means all the same. The question is just saying that 3 lines intersect at one point and form 6 angle. The 6 angles are not all the same. Given that, what is the smallest possible largest angle. Obviously, if all angles could be congruent, then, it would be 6 60° angles. However, they aren't. So, to minimize the largest angle, we can just make 1 angle 61° and another 59°. Therefore, the answer should be C which is 61° as you would have the 6 angles being:

59°, 60°, 60°, 60°, 60°, and 61°.

The distance we have to hike to reach the top of the mountain is

2.92 miles.

We know a right-angled triangle has three sides they are -: Hypotenuse,

Opposite and Adjacent.

We can remember SOH CAH TOA which is,

sin = opposite/hypotenuse, cos = adjecen/hypotenuse and

tan = opposite/adjacent.

Given, A mountain has a 20-degree slope and is 1 mile tall and we have to hike the mountain so we want to know the distance.

Here hypotenuse is the distance we have to hike and according to the reference, the angle opposite has a distance of 1 mile.

We know sin = opposite/hypotenuse.

sin20° = 1/hypotenuse.

0.342 = 1/hypotenuse.

hypotenuse = 1/0.342.

hypotenuse = 2.92 miles.

if you were to create a two way table, it would make sense, but you would still need more information.

Parent and meal choice describes the variables he can use in the first row and first column of his table.

The sample space S of a random experiment is defined as the set of all possible outcomes of an experiment. In a random experiment, the outcomes, also known as sample points, are mutually exclusive.

Given, Ketut is organizing a barbecue for his parents. He knows that 13 of his mom’s friends prefer hot dogs and 9 of his dad’s friends prefer hamburgers.

Variable in a graph should be an object, event, idea, feeling, time period, or any other type of category you are trying to measure. There are two types variables-independent and dependent.

#SPJ6

Answer:

x = 6, and x = 1

Step-by-step explanation:

If each expression equals y, the simplest approach would be to equate them;

x^2 - 5x + 7 = 2x + 1 => Isolate all the terms on one side

x^2 - 5x - 2x + 7 - 1 = 0 => Combine like terms

x^2 - 7x + 6 = 0 => solve using quadratic equation

x = ( - (- 7) + √( - 7)^2 - 4 * 1 * 6 )/ 2 * 1

= 7 + √25 / 2 = 7 + 5 / 2

= 6

x =  ( - (- 7) - √( - 7)^2 - 4 * 1 * 6 )/ 2 * 1

= 7 - √25 / 2 = 7 - 5 / 2

= 2 / 2 = 1

2y+7x= -5 + 5y-7x=12

a = 25

b = 12

Hi there !

a + b = 37

a = 2b + 1

replace a

(2b + 1) + b = 37

3b = 37 - 1

3b = 36

b = 36 : 3

b = 12

a = 2×12 + 1

a = 24 + 1

a = 25

a + b = 37

25 + 12 = 37

37 = 37 (true)

Answer:

1/3

Step-by-step explanation:

If you want to write the fraction in its lowest terms, all you have to do is simplify!! Simplifying is easy; all you have to do is divide on the top and bottom of the fraction by the same number.

So, to simplify 6/18, figure out what the highest number is that can go into both numbers in the fraction. For this problem, the highest number is 6.

6 divided by 6 is 1.

18 divided by 6 is 3.

The simplified answer comes out as 1/3...you can also check it by multiplying 1 and 3 by 6.

1 multiplied by 6 is 6.

3 multiplied by 6 is 18.

So, 6/18 in lowest terms is 1/3!!

I hope you understood...have a great day :)
