Answer:

Its A. I took the quiz.

Step-by-step explanation:

Soluions for the given expression in the given interval will be {0, π/2, 3π/2}.

Option A will be the answer.

Given expression in the question,

[tex]\text{sin}^2(\theta)=2\text{sin}^2(\frac{\theta}{2} )[/tex]

[tex][2\text{sin}(\frac{\theta}{2} )\text{cos}(\frac{\theta}{2} )]^2=2\text{sin}^2(\frac{\theta}{2} )[/tex]

[tex]4\text{sin}^2(\frac{\theta}{2} )\text{cos}^2(\frac{\theta}{2} )=2\text{sin}^2(\frac{\theta}{2} )[/tex]

[tex]4\text{sin}^2(\frac{\theta}{2} )\text{cos}^2(\frac{\theta}{2} )-2\text{sin}^2(\frac{\theta}{2} )=0[/tex]

[tex]2\text{sin}^2(\frac{\theta}{2} )[2\text{cos}^2(\frac{\theta}{2} )-1)]=0[/tex]

[tex]\text{sin}\frac{\theta}{2}=0[/tex]

[tex]\frac{\theta}{2} =n\pi[/tex]

[tex]\theta=2n\pi[/tex] [Here, n = integer]

[tex]\theta=0,\pi,2\pi.....[/tex]

Therefore, [tex]\theta=0[/tex] [Since, [tex]0\leq \theta < 2\pi[/tex]]

[tex]2\text{cos}^2(\frac{\theta}{2})-1=0[/tex]

[tex]\text{cos}\theta=0[/tex]

[tex]x=\frac{\pi}{2}+\pi n}[/tex] [Here, n = integer]

Therefore, [tex]\theta=\frac{\pi}{2},\frac{3\pi}{2}[/tex] [Since, [tex]0\leq \theta < 2\pi[/tex]]

    Hence, soluions for the given expression will be {[tex]0,\frac{\pi}{2} ,\frac{3\pi}{2}[/tex]}.

Answer:

The equation that represents the number of minutes that Imay talk using the card is [tex]m =28.571\cdot C[/tex].

Step-by-step explanation:

From statement we know that balance ([tex]C[/tex]), measured in US dollars, is directly proportional to remaining call time ([tex]m[/tex]), measured in minutes. That is:

[tex]C \propto m[/tex]

[tex]C = k\cdot m[/tex] (Eq. 1)

Where [tex]k[/tex] is the proportionality ratio, measured in US dollars per minute.

If we know that [tex]k = 0.035\,\frac{USD}{min}[/tex], then the equation is:

[tex]C = 0.035\cdot m[/tex]

Now we clear remaining call time within equation:

[tex]m =28.571\cdot C[/tex]

The equation that represents the number of minutes that Imay talk using the card is [tex]m =28.571\cdot C[/tex].

Answer:

Sample Response: When you divide 153 by 3, there is no remainder. This means that 3 goes into 153 evenly and so there can be the same number of parakeets in each cage.

Answer:

x = 10

Step-by-step explanation:

-x - 4 = 4x - 54

Add x to both sides

-4 = 5x - 54

Add 54 to both sides

50 = 5x

Divide both sides 5

10 = x

Answer:

k= -1

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

(10k-16)+11= -2

[tex](\frac{1}{2} ) (10k)+(\frac{1}{2} )(-16)+11 = -2[/tex]

(5k)+(-8+11)= -2

5k+ 3= -2

Step 2: Subtract 3 from both sides.

5k+3−3=−2−3

5k=−5

Step 3: Divide both sides by 5.

[tex]\frac{5k}{5} = \frac{-5}{5}[/tex]

k= -1

Step-by-step explanation:

Answer:

a) all real numbers

b) v = -2.5

Step-by-step explanation:

a) 2x - 1.5 = 2x - 1.5

subtract 2x from both sides of the equation

2x - 1.5 - 2x = 2x - 1.5 - 2x

1.5 = 1.5

since 1.5 will always equal 1.5 regardless of what x is,

the solution is all real numbers

b) 2v + 4 = -1

subtract 4 from both sides of the equation

2v + 4 - 4 = - 1 - 4

2v = -5

divide both sides of the equation by 2

2v/2 = -5/2

v = -2.5

Answer:

1.8m per minute

Step-by-step explanation:

Answer:

[tex]\frac{1.8 \ m}{1 \ min}[/tex] ; (1.8 meters per minute)

Step-by-step explanation:

Use dimensional analysis to solve this problem.

The proper units of conversion are given in parentheses on this question: 100 cm = 1 m.

Start with the given value, 3 centimeters/1 second.

Convert this rate to meters/minute by multiplying 3 cm/1 sec by 1 m/100 cm.

The top and bottom units should cancel out, so that's how you know to put the cm units on the bottom to cancel out with the 3 cm on the top.

Multiply the fractions together. The "cm" units cancel out.

Now you want to make the bottom units = minutes. There are 60 seconds in 1 minute, so you can use [tex]\frac{60 \ sec}{1 \ min}[/tex] to multiply with [tex]\frac{3\ m}{100 \ sec}[/tex].

The "seconds" unit cancels out, so you are left with meters on the top and minutes on the bottom. Multiply the fractions together.

We want the rate to be meters per minute (1), so completely simplify this fraction and divide the fraction by (100/100), so the denominator is 1 min.

Answer:

She spent $38.7 on the remaining boxes.

Step-by-step explanation:

total number of boxes of pencil bought by Ms. Smith, = 30 boxes

cost of each box = $2.15

fraction of boxes of pencil used = 6 / 15

number of boxes of pencil used = [tex]\frac{6}{15} *30 \ boxes = 12 \ boxes[/tex]

number of boxes of pencil remaining = 30 boxes - 12 boxes = 18 boxes

Cost of the 18 boxes remaining = 18 x $2.15

                                                    = $38.7

Therefore, she spent $38.7 on the remaining boxes.

Answer:

0.8 ounces

Step-by-step explanation:

Given that:

Ounce of basil Hayley wishes to purchase = 5/6 ounces

Since the scale is displaying as decimal, then the fraction of basil to be purchased will be could be converted to decimal;

5/6 = 0.83333

To the nearest tenth ;

5/6 = 0.8 ounces

Once the display on the scale shows 0.8, then it is equivalent to 5/6 ounces of basil.

Answer:

After 20 days, they will have the same number of cards

Step-by-step explanation:

Given;

number of cards with Anthony, = 260 cards

rate of his sale = 5 cards/day

number of cards with Ben, = 100 cards

rate of his purchase, = 3 cards/day

let the number of days when they will have the same number of card = n

set up the linear equation, consider sale as subtraction from the initial value and also consider purchase as an addition to the initial value.

260 - 5n = 100 + 3n

260 -100 = 3n + 5n

160 = 8n

n = 160 / 8

n = 20 days

Therefore, after 20 days, they will have the same number of cards

Answer:

x=3

y=2

Step-by-step explanation:

you can either use substitution or elimination method

I find substitution method better

substitute x with 3 and in this method u use one of the equation

10(2)-20y=-10

20-20y=-10=2

y=2

now use y=2 with the same equation

10x-40=-10=30

10x=30

x=3

therefore

x=3

y=2
