I NEED HELP can anyone help me, please??

We have been given graph of a sinusoidal function. We are asked to write function formula for our given graph.

We know that [tex]\sin(0)=0[/tex] and [tex]\cos(0)=1[/tex]. We can see that our given function is starting at origin, so our graph is sine function.

We know that general form of sine is [tex]y=A\sin[B(x-c)]+D[/tex], where,

A = Amplitude,

Period: [tex]\frac{2\pi}{B}[/tex]

C = Horizontal shift,

D = Vertical shift.

We have been given that function has no horizontal shift, so the value of C is 0.

We can also see that midline of our function is x-axis, so there is no vertical shift as well that is [tex]D=0[/tex].

We can see that function goes up to 1 from midline and goes down to [tex]-1[/tex] from midline, so amplitude of function is 1 that is [tex]A=1[/tex].

We can see that period of our given function is [tex]4\pi[/tex] because it completes one cycle from [tex]-\pi[/tex] to [tex]3\pi[/tex]

[tex]4\pi=\frac{2\pi}{B}[/tex]

[tex]B=\frac{2\pi}{4\pi}=\frac{1}{2}[/tex]

[tex]y=\sin(\frac{1}{2}x)[/tex]

We can see that our function is reflected about x-axis, so our function will be [tex]y=-f(x)[/tex].

[tex]y=-\sin(\frac{1}{2}x)[/tex]

Therefore, our required function is [tex]y=-\sin(\frac{1}{2}x)[/tex].

Answer:

It would be number 2. measure of angle BAC is equal to half the measure of angle BOC.

Step-by-step explanation:

This is because of inscribed angles.

In the diagram below of circle O, OB and OC are radii, and chords AB, BC, and AC are drawn. The correct statement is B. m < BAC = 1/2 m < BOC.

From the information given, (a + b) + (a + c) + (b + c) = 180°

2a + 2b + 2c = 180°

2a + 2b = 180° - 2c

2(a + b) = 180° - 2c

Therefore, m < BAC = 1/2 m < BOC.

In conclusion, the correct option is B.

Step-by-step explanation:

i looked it up on a website and got this question right on my test

The given expression is a linear function and has a unique solution.

Given,

For what value of b, would the equation 3/4(12x−9)+b/4=5−3(2−3x) have infinitely many solutions?

Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in set of y. x is the independent variable while Y is the dependent variable.

Here,
3/4(12x−9)+b/4=5−3(2−3x)
12x - 27 / 4 + b / 4 = 5 - 6 + 9x
12x - 9x = -1 + 27/4 - b / 4
3x = 23 - b / 4

Here the expression is a linear function of x, so the expression has a unique solution not infinitely many solutions.

Thus, the given expression is a linear function and has a unique solution.

Step-by-step explanation:

The Quadratic function is the best models for the given graph.

A quadratic function is a "polynomial function with one or more variable in which highest exponent of variable is two".

According to the question,

Horizontal axis or x-axis quadratic function of numbered 2-8 and vertical axis or y-axis quadratic function numbered to 10-50.

In order to find the best models function is quadratic function.

f(x) = ax²+bx+c   a < 0

Domain = All real numbers

Range y ≤ f(-[tex]\frac{b}{2a}[/tex])

Increases on left of x = -[tex]\frac{b}{2a}[/tex]

Decreases on right of x = -[tex]\frac{b}{2a}[/tex]

The vertex of the parabola lies on the axis of the parabola so the graph of the quadratic function increases on one side axis and decreases on the other side.

Answer:

0.233298 kg is the mass of 234 ml of water

Step-by-step explanation:

Mathematically,

mass = density * volume

henry, to get the mass of that volume, we shall need to multiply it by the density of water.

The density of water is 997 kg/m3

To achieve consistency in units, we shall convert 234 ml to m3

Mathematically 1ml = 1 * 10^-6 m^3

Thus, 234 ml = 234 * 10^-6 m^3

Therefore the mass of water will be = 234 * 10^-6 * 997 = 0.233298 kg

1-0.5357142857142857=0.4642857142857143

Answer:

= 46%

Step-by-step explanation:

● Original = 84 gallons

● New = 45 gallons

● Decrease = 84 - 45 = 39 gallons

If 84 gallons = 100%

What about 39 gallons = ?

= (39 x 100) ÷ 84

= 3900 ÷ 84

= 46.42

= 46%

Step-by-step explanation:

To solve this problem, we need to find the Greatest Common Factor (GCF) which is the greater factor possible in common for all three numbers 5000, 2500 and 245 liters.

5,000 | 2

2,500 | 2

1,250  | 2

625    | 5

125     | 5

25      | 5

5        | 5

1

So, [tex]5,000 = 2 \times 2 \times 2 \times 5 \times 5 \times 5 \times 5[/tex], [tex]2,500 = 2 \times 2 \times 5 \times 5 \times 5 \times 5[/tex]

245 | 5

49   | 7

7     | 7

1

[tex]245 = 5 \times 7 \times 7[/tex]

As you can observe, the greatest common factor is 5, because it's the greater number in common for all three numbers.

Therefore, the greatest recipient possible must be 5 liters capacity.

Answer:

[tex]p\geq 1.15(4,500)[/tex]

Step-by-step explanation:

If she makes a minimum profit, we need to use the symbol [tex]\geq[/tex], which indicates minimum quality.

Let's call [tex]p[/tex] profit, so the inequality which represent this problem would be

[tex]p\geq 1.15(4,500)[/tex]

The price of the car is multiplied by 1.15, because she must add her profit comission which is 0.15 or 15%.

Therefore, the right answer is the last choice.

Answer:

Step-by-step explanation:

Let x be the random variable representing the height of players on the football team. Since it is normally distributed and the population mean and population standard deviation are known, we would apply the formula,

z = (x - µ)/(σ/√n)

Where

x = sample mean

µ = population mean

σ = standard deviation

n = number of samples

From the information given,

µ = 74 inches

σ = 1 inch

n = 50

x = 74 inches

the probability that a player is less than 74 inches tall is expressed as

P(x < 74)

For x = 74,

z = (74 - 74)/(1/√50) = 0

Looking at the normal distribution table, the probability corresponding to the z score is 0.5

Therefore,

P(x < 74)

The players less than 74 inches is

0.5 × 50 = 25 players

Answer:

8 weeks

Step-by-step explanation:

We are to find the number of weeks that they will have the same account balance.

Let the number of weeks be x.

Megan started by putting $80 in her account, and she will deposit an additional $15 each week. This means after x weeks, she will have:

80 + 15x

Noah made no initial deposit, but he will add $25 more each week. After x weeks, he will have:

25x

To find the number of weeks for their amounts to be the same, we equate their amounts to one another:

80 + 15x = 25x

Collexting like terms and solving for x:

80 = 25x - 15x

80 = 10x

=> x = 80 / 10 = 8 weeks

After 8 weeks, the money in their accounts will be the same.

Answer:

Value of House = $98000

Step-by-step explanation:

The sum of all of the assets and liabilities + value of the house =  $101,800

Value of House + $900 - $3400 + $16900 - $16300 + $4500 + $1200 = $101,800

=> Value of House + $3800 = $101,800

=> Value of House = $101,800 - $3800

=> Value of House = $98000

The current value of Peter's house will be $98000.

A table is given which shows Peter's net worth and assets are shown as positive numbers, and liabilities are shown as negative numbers.

We have to find out the current value of Peter's house if , Peter's net worth is $101,800.

What will be the resulting value ;  35 - 10 - 5 + 10 = ?  

The resulting value will be 30.

As per the question ;

The sum of all of the assets and liabilities plus value of the house is equal to $101,800.

Assume value of house = x

⇒ x + $900 - $3400 + $16900 - $16300 + $4500 + $1200 = $101,800

⇒ x + $3800 = $101,800

⇒ x = $101,800 - $3800

⇒ x = $98000

Thus , the current value of Peter's house will be $98000.
