What is the domain of f?

Answer:

Step-by-step explanation:

[tex]cos15=cos\frac{30}{2}[/tex] so the angle we will use in our identity is 30 degrees. The formula is

[tex]cos\frac{30}{2}=\sqrt{\frac{1+cos30}{2} }[/tex] which simplifies to

[tex]\sqrt{\frac{1+\frac{\sqrt{3} }{2} }{2} }[/tex] which simplifies to

[tex]\sqrt{\frac{\frac{2+\sqrt{3} }{2} }{2} }[/tex] which simplifies to

[tex]\sqrt{\frac{2+\sqrt{3} }{4} }[/tex] which simplifies, finally, to

[tex]\frac{\sqrt{2+\sqrt{3} } }{2}[/tex], choice a.

Answer:

[tex]\frac{1}{4} \div 3 = \frac{\frac{1}{4} }{3} = \frac{1}{12}[/tex]

Answer:

1/12

Step-by-step explanation:

1/4 / 3/1

1*1/4*3

= 1/12

Answer:

No

Answer:

so its means that ahmad can blow balloons at fastest rate...

Step-by-step explanation:

Saima:

15b = 20min

1 b = 1 min 20sec

Sarah;

18b = 25min

1 b = 1 min 23sec

ahmad;

16b = 21min

1 b = 1 min 19sec

Bilal;

12b = 23min

1 b = 1 min 55 sec

Answer:

y = 4

Step-by-step explanation:

Since the 2 rectangles have the same area, then

12.5 × 2y = 5 × 20

25y = 100 ( divide both sides by 25 )

y = 4

Answer:

y = 4/3x - 2, B is your answer

Step-by-step explanation:

Y intercept is the number next to slope(b).

The co efficient of x will be your slope so therefore the co efficient of x will be 4/3

y is always there because it will always be the dependent variable on the left side.

Answer:

the answer is B

Step-by-step explanation:

Y=(slope)x+y-intercept/y=mx+b

plug in the slope then the Yy intercept

im not sure but i think its a bargraph if the answer is coreect please tell

Answer:

6,561

Step-by-step explanation:

Given that;

[tex]log_3x + log_9x = 12\\log_3x+1/2log_3 x = 12\\(1+1/2)log_3x = 12\\3/2log_3x = 12\\log_3x = 12 *2/3\\log_3x = 8\\x = 3^8\\x = 6,561[/tex]

Hence the value of x is 6,561

Answer:

15 horas

Step-by-step explanation:

Representemos:

El número de horas que Patrice puede pintar solo = P = 10 horas

El número de horas que April puede pintar por su cuenta = A = X horas

El número total de horas que pueden trabajar juntos para hacer el mismo trabajo = T = 6

Por tanto, nuestra fórmula es:

1 / P + 1 / A = 1 / T

1/10 + 1 / A = 1/6

1 / A = 1/6 -1/10

Denominador común más bajo = 30

1 / A = 5 - 3/30

1 / A = 2/30

1 / A = 1/15

Multiplicar cruzada

A × 1 = 15 × 1

A = 15 horas

Por lo tanto, la cantidad de horas que April puede pintar cuatro habitaciones si trabaja sola es de 15 horas.

Answer:

A. 96

C. 48

D. 24

Step-by-step explanation:

Multiples of 8

8 = 8, 16, 24, 32, 40, 48, 56, and 64, 72, 80, 88, 96, 104,.......

Multiples of 12

12 = 12, 24, 36, 48, 60, 72, 84, 96, 108,........

Common multiples of 8 and 12 = 24, 48, 72 and 96

The correct answers are:

A. 96

C. 48

D. 24

Answer:

The equation would be y=mx+b so plugging in the slope which is, 11, so y=11x+b WE DO NOT KNOW THE Y INTERCEPT

Answer:

20% loss

Step-by-step explanation:

(32000-40000)/40000 * 100 = -20%

Answer:

Step-by-step explanation:

CP of a TV=40000

Sp of a TV=32000

here CP is greater than Sp so there is loss

loss=CP-SP

=40000-32000

=8000

loss%=loss amount/cp*100%

=8000/40000*100

=800000/40000

=20%

Sorry if you need to show work it's really hard to type it out since I don't have the symbols

Answer:

Step-by-step explanation:

6 no

1.angle 2=92 degree(being vertically opposite angle)

2.angle 1+33+92=180(sum of interior angles of a triangle)

angle 1+125=180

angle 1=180-125

angle 1=55

3.angle 3+angle 2+115+90=360(sum of four angles is always 360 degree)

angle 3+92+205=360

angle 3+297=360

angle 3=360-297

angle 3=63

Answer:

93.8858 pounds

How to convert:

1 pound (lb) = 0.479305709 quart (qt). Pound (lb) is a unit of Weight used in Standard system. Quart (qt) is a unit of Volume used in Cooking system. Please note this is weight to volume conversion, this conversion is valid only for pure water at temperature 4 °C.

1 US qt = 0.946352946 liters = 0.946352946 kg of pure water at temperature 4 °C.

US oz = 28.349523125 g

US fl oz = 29.5735295625 ml (milliliters) = 29.5735295625 g (grams) of pure water at temperature 4 °C.

US cup = 8 fl oz = 236.5882365 ml (milliliters) = 236.5882365 g (grams) of pure water at temperature 4 °C.

The US liquid quart equals to 0.946352946 liters.

Answer:

45 quarts is equal to exactly 93.8858 pounds.

Step-by-step explanation:

1 quart (qt) = 2.086351113 pound (lb).

Multiply 2.086351113 pounds by 45 to get your answer.

Answer:

4 there all adding by 13 so do 13-9 to get 4

Answer: 22

Step-by-step explanation: The answer is 22 because all you have to do it keep adding 13 to the number like.

9 + 13 = 22

22 + 13 = 35

35 + 13 = 48

48 + 13 = 61
