The domain (input values) of the sine function is:
O A. angle measures between 0 and 7 radians.
O B. angle measures less than 90°.
C. all angle measures, including negative angles.
O D. angle measures between 0 and 21 radians.

Answer:

x = 20

y = 20√2  

Step-by-step explanation:

This is a 45 - 45 - 90° special right triangle

In a 45 - 45 - 90° triangle the legs are congruent and the hypotenuse = leg * √2

If one leg = 20 then the other leg also = 20

Thus, x = 20

If leg = 20

Then hypotenuse = 20 * √2 or 20√2

Thus, y = 20√2

Answer:

Step-by-step explanation:

The anwser is 479 - 2:5 as a decimal is .4 , 342 x .4 is 126.8

342+126.8 = 178.8

round it and get 479

By using given ratio, Members does the club have are 1197.

"A ratio can be defined as the relationship or comparison between two numbers of the same unit to check how bigger is one number than the other one."

We have,

Ratio of health club members who use trainers and who do not  is 2:5.

Members who use trainers = 342

Members who does not use trainers

= [tex]\frac{342}{2}[/tex]×[tex]5[/tex]

= 171 × 5

= 855

Total members

= 855 + 342

= 1197

Hence, Members does the club have are 1197.

Answer:

Ethan cycles from home for x km at 9km/h to the MRT station.

He waited for 3 mins before catching the next MRT train.

The MRT train travels at an average speed of 60km/h.

He walks for 1/2km at an average speed of 6km/h before reaching his school.

The distance from his home to the school by the above route is 12km and the total time he spent is 28 mins.

:

(i) Express, in terms of x, the time he spent cycling from home to the MRT station.

time = dist/speed

f(x) = x%2F9

:

(ii) Find the distance travelled by Ethan when he was travelling to school using the MRT

dist by train

d = 12 - x - .5

d = 11.5 - x

(iii) Form an equation in x and solve it.

Subtract the 3 min of waiting, change to hrs: 25/60 = 5%2F12

Write a time equation

bike time + train time + walk time = 5/12 hrs

x%2F9 + %28%2811.5-x%29%29%2F60 + .5%2F6 = 5%2F12

multiply by 180, resulting in

20x + 3(11.5-x) + 30(.5) = 15(5)

20x + 34.5 - 3x + 15 = 75

20x - 3x + 49.5 = 75

17x = 75 - 49.5

17x = 25.5

x = 25.5/17

x = 1.5 km by bike

but where is the diagram

Elena drops her pencil into her cup and notices that it just fits diagonally. The pencil is 17 cm long and the cup is 15 cm tall. The diameter of the cup is 8 cm.

The Pythagoras theorem states that the square of the longest side must be equal to the sum of the square of the other two sides in a right-angle triangle.

Elena drops her pencil into her cup and notices that it just fits diagonally. The pencil is 17 cm long and the cup is 15 cm tall.

Answer:

10 pizzas

Step-by-step explanation:

Jaxson is throwing a pizza party. He has 1\tfrac{1}{4}1 4 1 ​ pounds of cheese available and he needs \tfrac{1}{8} 8 1 ​ pound of cheese to make each pizza. How many pizzas can he make?

We can interprete the above question as:

1/8 pounds of cheese = 1 pizza

1 1/4 pounds of cheese = x pizzas

Cross Multiply

1/8 × x = 1 1/4 × 1

x = 1 1/4 ÷ 1/8

x = 5/4 ÷ 1/8

x = 5/4 × 8/1

x = 10 pizzas

x = 10 pizzas

Answer:

3, 1

Step-by-step explanation:

Slope is rise/run, with the rise being the y increase, and x being the x increase.

Since the run represented is 3, and the rise is 9:

9/3 = 3

The y-intercept is the value of f(x) (which is y) when x = 0

since the equation of the line is:

f(x) = 3x + b

we need to go down 3 units of x since x = 0

3 x 3 = 9

10 - 9 = 1

b = 1

The y-intercept is 1.

Answer: B

Uh... nothing much to say for this one. When you divide with fractions, you always flip the second number. 1/2 flipped is 2/1, or 2. So the final problem is 50x2, which is 100. And yeah, that's all I have to say...

Answer:

B. 50 * 2

Step-by-step explanation:

When there is a division sign and then you are having a fraction which also means dividing you will in the end just be multiplying. and we would be  *2 because you were 1/2 and if you flip  the fraction it = 2

The length of string = 32.35 meter (Approx.)

Step-by-step explanation:

Given:

Vertical height of kite = 22 meter

Angle with horizontal = 43°

Find:

The length of string

Computation:

Using trigonometry function;

Vertical height of kite [Perpendicular]  = 22 meter

The length of string[Hypotenuse]

Sin θ = Perpendicular / Hypotenuse

Sin 43 = 22 / Hypotenuse

0.68 = 22 / Hypotenuse

Hypotenuse = 22 / 0.68

Hypotenuse = 32.35 meter

The length of string = 32.35 meter (Approx.)

Answer:

m∠N = 32°

NQ = 106°

When finding inscribed angles like ∠N with the intercepted arc, the equation is ∠N=1/2MP. (Inscribed angles are always half the degree of the arc length.) Plug in the corresponding value to get ∠N=1/2(64) to get 32°. When finding the angle of the intercepted arc with inscribed angles like NQ, the equation is NQ=2(∠P). Plug in the corresponding value to get 2(53) to get 106°.

Answer:

The mode of the data sets

Step-by-step explanation:

The measure of central tendency is a value that aims to give the description of a data set by providing a pointer to the central position of the data set

The item under comparison = The most common women running shoe color and the most common women sandal color

The characteristics of the items under comparison = Color (nominal characteristic)

Therefore, the measure of central tendency will aim to show the frequency with which particular colors are worn, which is represented by the mode of the data set
