Which values are two of the possible solutions to the equation? sin(5x-pi)= sqrt2/2, for x is greater than or equal to 0 and less than 2pi
A) pi/20, 3pi/20
B) pi/4, 7pi/20
C) pi/4, 7pi/4
D) 5pi/4, 7pi/4

Step-by-step explanation:

The two of the possible solutions to the equation sin(5x - π) = (√2)/2 are,

⇒ (π/4, 7π/4).

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Here, The given equation is;

sin(5x - π) = (√2)/2

Now, We can write 2 as √2 × √2

So, We get;

sin(5x - π) = √2/√2*√2

sin(5x - π) = 1/√2

Taking sin⁻¹ on both side,

sin⁻¹ (sin(5x - π)) = sin⁻¹ (1/√2)

5x - π = sin⁻¹ (1/√2)

Hence, From the trigonometry table we know that sin⁻¹ (1/√2) = π/4

Thus,

5x - π = π/4

5x = π + π/4

5x = 5/4π

Divide by 5 on both side, we get

x = π/4

Now, since x < 2π, then it means it is in the fourth quadrant. Thus;

x = 7π/4

So, the two of the possible solutions to the equation sin(5x - π) = (√2)/2 is (π/4, 7π/4).

Answers

Answer:

20 cakes

Step-by-step explanation:

Given

28 cakes in 7 days

Required

Determine the number of cakes in 5 days

Represent the required with x. The question illustrates proportionality.

First, we need to represent the given and required as a ratio

[tex]28 : 7 = x : 5[/tex]

Convert ratios to fraction

[tex]\frac{28}{7} = \frac{x}{5}[/tex]

[tex]4 = \frac{x}{5}[/tex]

Solve for x

[tex]x = 4 * 5[/tex]

[tex]x = 20[/tex]

Compared to last month, there was a 50% increase in the number of houses sold this month.

Answers

Answer:150%

Step-by-step explanation:because 50% increases

The number of houses sold this month are -

y = 3x/2.

What is percentage?

In mathematics →

a percentage is a number or ratio expressed as a fraction of 100.it is often denoted using the percent sign "%".

Given is that compared to last month, there was a 50% increase in the number of houses sold this month.

Assume that the number of houses sold of previous moth were [x]. Then, we can write -

y = {x} + 50% of {x}

y = {x} + (50/100) × {x}

y = {x} + {x/2}

y = 3x/2

Therefore, the number of houses sold this month are -

y = 3x/2.

Triangle ABC measures are as follows; Angle A measures 30 degrees, angle B measures (3x-9) degrees and angle C measures 29 degrees. What is the value of x?

Answers

Answer:

x = 43 1/3 degrees

Step-by-step explanation:

sum of interior angles in a triangle = 180 degrees

30 + (3x - 9) + 29 = 180

30 + 29 + (3x - 9) = 180

59 + (3x - 9) = 180

(3x - 9) = 180 - 59

(3x - 9) = 121

3x = 121 + 9

3x = 130

x = 43 1/3

okay so it says Sophia's friend has saved $118 so she already knows she has $118 and then the next step is to figure out about Part B so she does not know how many songs you can afford to buy so the expression in Part B whatever the expression is if you figured out the answer to Part B and there's a number what you want to do what you would want to divide that number into 118 to see how how many equal groups you can make and you don't want to go overboard 18 so what you would want to do it if you would want to do if you figure out the number to expression be in the boring part B they don't want to take that and keep making a go go to that until you reach 118 and then you would get your total

The half-life of a certain radioactive substance is 45 days. There are 6.2 grams present initially. On what day
will there be less than 1 gram remaining? Day

Answers

Answer:

There will be less than 1 gram of the radioactive substance remaining by the elapsing of 118 days

Step-by-step explanation:

The given parameters are;

The half life of the radioactive substance = 45 days

The mass of the substance initially present = 6.2 grams

The expression for evaluating the half life is given as follows;

[tex]N(t) = N_0 \left (\dfrac{1}{2} \right )^{\dfrac{t}{t_{1/2}}[/tex]

Where;

N(t) = The amount of the substance left after a given time period = 1 gram

N₀ = The initial amount of the radioactive substance = 6.2 grams

[tex]t_{1/2}[/tex] = The half life of the radioactive substance = 45 days

Substituting the values gives;

[tex]1 = 6.2 \left (\dfrac{1}{2} \right )^{\dfrac{t}{45}[/tex]

[tex]\dfrac{1}{6.2} = \left (\dfrac{1}{2} \right )^{\dfrac{t}{45}[/tex]

[tex]ln\left (\dfrac{1}{6.2} \right ) = {\dfrac{t}{45} \times ln \left (\dfrac{1}{2} \right )[/tex]

[tex]t = 45 \times \dfrac{ln\left (\dfrac{1}{6.2} \right ) }{ln \left (\dfrac{1}{2} \right )} \approx 118.45 \ days[/tex]

The time that it takes for the mass of the radioactive substance to remain 1 g ≈ 118.45 days

Therefore, there will be less than 1 gram of the radioactive substance remaining by the elapsing of 118 days.

Let y represent the total cost to rent a car and m represent the number of kilometers a person drives. If you are solving the equation, how many km would you have to drive for the total cost to be the same?
0.35m + 25.95= 0.55m + 19.95

Let adult tickets be a and children tickets be c.

System of equations as per given:

a  + c = 4753a + 2c = 1200

Substituting c in the second equation

c = 475 - a3a + 2(475 - a) = 12003a + 950 - 2a = 1200a = 1200 - 950a = 250

Then, finding c:

c = 475 - 250 = 225

They can only be seen when the moon shines behind them, and what is more, with the more cunning sort it must be a moon of the same shape and season as the day when they were written.'"2."Bilbo never forgot the way they slithered and slipped in the dusk down the steep zig-zag path into the secret valley of Rivendell. The air grew warmer as they got lower, and the smell of the pine-trees made him drowsy, so that every now and again he nodded and nearly fell off, or bumped his nose on the ponys neck.
