The general equation of the sinusoid is  [tex]f(x)=sinx[/tex]

"A sine wave or sinusoidal is a continuous or mathematical curve which is used to describe a smooth periodic oscillation."

We know,

A Sinusoidal function is a function that can be modelled using a sine wave.

The sine graph repeats itself after a period of 2π, which shows the function is periodic with a period of 2π.

f (x) = sin x and f (x) = cos x are similar apart from a phase shift, both functions are sinusoidal.

f (x) = tan x is a trigonometric function, but its graph is completely different.

The graph of a sinusoidal function is a smooth periodic graph.

The graph is continuous all over the x-axis and also it repeats itself after every fixed interval.

∵ A phase shift is the only difference between sine and cosine, any sinusoidal function that can be modelled using sine can also be modelled using cosine.

The general sinusoidal function is  [tex]f(x)=[/tex]±[tex]a.sin(b(x+c))+d[/tex]

Where as,

± controls the reflection across the x - axis, coefficient a controls the amplitude , constant d controls the vertical shift, coefficient b controls the horizontal stretch.

∴ The general equation of the sinusoid is  [tex]f(x)=sin x[/tex]

Step-by-step explanation:

Answer:

evaluate parenthesis first:

67/100(consider 67% out of 100) x 119 = 79.73

Answer:

79.73

Step-by-step explanation:

First, it would be finding 67% of 119

Then we find 10% = 11.9   and 1% = 1.19

The 11.9 multiplied by 6 to equal 71.4 and 1.19 multiplied by 7 to equal 8.33

Then add 71.4 and 8.33 to get the answer of 79.73.

Answer:

17 meters

Step-by-step explanation:

Plug x=30 into the equation H(x) = 11 + 0.2x

H(30) = 11 + 0.2 * 30

H(30) = 11 + 6

H(30) = 17

Thus, the answer is 17 meters.

Answer: -30h +9

Step-by-step explanation:

Answer:

25h²-30h+9

Step-by-step explanation:

we need to multiply binomials

to multiply binomials using the FOIL method, we first multiply the First terms (F for first) together (in this case, 5h and 5h)

That gives us 25h²

Next up, we do the Outer terms (O for outer), which in this case are 5h and -3. This gives us -15h

then, we do the two Inner terms, (I for inner)  which are -3 and 5h. This gives us -15h

finally, we do the two Last terms (L for last), which are -3 and -3. This gives us 9

here's what we have  from doing FOIL:

25h²-15h-15h+9

we can combine the 2 -15h's together to get:

25h²-30h+9

Answer:

1332.8 ft^3

Step-by-step explanation:

separate the two figures into a flat cylinder and a flat box

Volume of a cylinder= [tex]\pi r^{2} h[/tex]

where radius= 3ft and height= 3ft

therefore

[tex]=\pi (3)^{2} (3) \\= 84.8 ft^{3}[/tex]

now for the flat box:

volume of box= [tex]w*l*h[/tex]

where width= 6ft, length= 16ft, height= 13ft

therefore

[tex]=(6)(16)(13)\\=1248 ft^{3}[/tex]

now add the volume of the cylinder and box together

[tex]84.8 + 1248\\= 1332.8 ft^{3}[/tex]

Answer:

3.5

Step-by-step explanation:

The interquartile range is the difference between the third and first quartile

IQR = Q3 - Q1

From the dot plot given :

The data, X could be culled :

X = 43, 44, 44, 44, 45, 45, 47, 48, 48

n = 9

Q3 = 3/4(n + 1)th term

Q3 = 3/4(10) = 7.5th term = (47 + 48) / 2 = 47.5

Q1 = 1/4(n + 1)th term

Q1 = 1/4(10) = 2.5th term = (44 + 44) / 2 = 44

Q3 - Q1 = 47.5 - 44 = 3.5

Complete question :

One gallon of gasoline in buffalo, New York costs $2.29. In Toronto, Canada, one liter of gas costs $0.91. There are 3.8 liters in one gallon. How much does one gallon of gas cost in Toronto?

Answer:

$3.458

Step-by-step explanation:

Given that :

Cost per gallon in Buffalo, New York = $2.29

Cost per Litre in Toronto, Canada = $0.91

Number of litres in 1 gallon = 3.8

The cost per gallon in Toronto, Canada will be :

3.8 * cost of a Litre

3.8 * $0.91 = $3.458

Hence, cost of a gallon in Toronto, Canada = $2.73

The distance between the boat and the hiker

To do this, we make of sine rule.

[tex]\frac{a}{\sin A} = \frac{b}{\sin B} =\frac{c}{\sin C}[/tex]

In this case:

[tex]x = ??[/tex]

[tex]X = 68[/tex]

[tex]a = 66[/tex]

[tex]A = 35[/tex]

So, we have:

[tex]\frac{x}{\sin 68} = \frac{66}{\sin 35}[/tex]

Make x the subject

[tex]x = \frac{66}{\sin 35} * \sin 68[/tex]

Using a calculator, we have:

[tex]x = \frac{66}{0.5736} * 0.9272[/tex]

[tex]x = 115.063* 0.9272[/tex]

[tex]x = 106.68[/tex]

[tex]x \approx 107[/tex]

Answer:

V would equal -7.1.

Step-by-step explanation:

It appears you have set the decimal points as commas. Let's remove that and replace it with decimal points. (AkA ".")

First, we move every term with "V" in this problem to the left.

-9.45 - 3.3v = 13.98

Next, we add -9.45 to 13.98 which equals 23.43.

We then make 3.3v negative.

-3.3v = 23.43

We then divide 23.43 and 3.3v by 3.3.

We cancel out 3.3v to leave 23.43/3.3.

We can now divide 23.43 by 3.3 to get -7.1.

V = -7.1

Answer:

V would equal -7.1.

Answer:

C and A

Step-by-step explanation:

So first, off, to find the length of a line, we can use pythagreons theorm.(A^2+B^2=C^2) The cahnge in x squared and the change in y squared will give us C, which is the line length. You can count the tiles like this:

From the bottom point, lets count up the x coordinates till we hit the x coordinates of the top point. I got 3.

Next is the y coordinates.

When I count up until I reach the top point, I get 7. Lets plug these numbers in:

3^2+7^2=C^2

Use the square root on eahc number except for the unknown(C)

=

9+49=c^2

Add the two numbers together:

=

58=c^2

Take square root:

7.61=c^2

This can just be rounded to 7.6

This looks like C

So that is your first answer.

Next we have a table.

We need to look at the section of people that have both brown hair and eyes.

When I look at the table, I see 30 people whom how both these charcteristics.

When you looka the total people in the bottom right corner, you see that there are 120 people.

We do not even need to calculate percentage.

30 is 1/4 of 120.

What is 1/4 of 100%

25%

So the people with both brown eye/hair color is 25%

THis looks like answer A

I hope this helps! :)
