Answer:

The period is 360° ( in radians, the period is 2π)

Step-by-step explanation:

For a sine/cosine (sinusoidal) function in the form

y = ASin(Bx-C) + D, we can say

A is the amplitude

360/B is the period

C is the phase shift

D is the vertical translation

The function given is y = 2Sinx

To find the period, we need 360/B. Since "B" is just "1", the period is

360/1 = 360

Answer:

The period of the function [tex]y = 2sinx[/tex] is [tex]2\pi[/tex]

Step-by-step explanation:

The sinosuidal functions have the following form

[tex]y = Asin (bx) +k[/tex]

Where A is the amplitude of the function

k is the vertical displacement

[tex]\frac{2\pi}{b}[/tex] is the period.

In this case we have the function

[tex]y = 2sinx[/tex]

Therefore the amplitude A = 2

The vertical displacement is k = 0

The period is [tex]\frac{2\pi}{1} = 2\pi[/tex] because b=1

Therefore the function completes a cycle every [tex]2\pi[/tex]

ANSWER

[tex]y = 5 \sin( \frac{6}{5} x - \pi)-4 [/tex]

EXPLANATION

The given function is

[tex]y = 5 \cos( \frac{3}{5} x - \pi) + 4[/tex]

The period of this function can be determined using the formula:

[tex]T= \frac{2\pi}{ |b| } [/tex]

.

The period is

[tex]T= \frac{2\pi}{ \frac{3}{5} } = \frac{10\pi}{3} [/tex]

Half the period of this function is:

[tex] \frac{ \frac{10\pi}{3} }{2} = \frac{5\pi}{3} [/tex]

The function which has this period is

[tex]y = 5 \sin( \frac{6}{5} x - \pi) -4[/tex]

The first choice is correct.

Hope this helps you out!

Answer:

All the polar coordinates of point P are [tex]P(4,-\frac{\pi}{3})=(4,2n\pi-\frac{\pi}{3})[/tex] and [tex]P(4,-\frac{\pi}{3})=(-4,(2n+1)\pi-\frac{\pi}{3})[/tex], where n is any integer and θ is in radian.

Step-by-step explanation:

It a polar coordinate is given as P(r,θ), then all the polar coordinates of point P  are defined as

[tex]P(r,\theta)=(r,2n\pi+\theta)[/tex]

[tex]P(r,\theta)=(-r,(2n+1)\pi+\theta)[/tex]

Where, n is any integer and θ is in radian.

The given point is

[tex]P(4,-\frac{\pi}{3})[/tex]

So, all the polar coordinates of point P  are defined as

[tex]P(4,-\frac{\pi}{3})=(4,2n\pi-\frac{\pi}{3})[/tex]

[tex]P(4,-\frac{\pi}{3})=(-4,(2n+1)\pi-\frac{\pi}{3})[/tex]

Therefore all the polar coordinates of point P are [tex]P(4,-\frac{\pi}{3})=(4,2n\pi-\frac{\pi}{3})[/tex] and [tex]P(4,-\frac{\pi}{3})=(-4,(2n+1)\pi-\frac{\pi}{3})[/tex], where n is any integer and θ is in radian.

Step-by-step explanation: They all divide evenly when divided by 30.

Answer:

The value of x is -3

Step-by-step explanation:

* Lets explain how to solve the problem

- The slope of a line that passes through points (x1 , y1) and (x2 , y2) is

  [tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

* Lets solve the problem

∵ The points (4 , 1) and (x , -6) lie on the same line

∵ The slope of the line is 1

- Let the point (4 , 1) is (x1 , y1) and the point (x , -6) ix (x2 , y2)

∵ x1 = 4 , x2 = x and y1 = 1 , y2 = -6

∴ [tex]m=\frac{x-4}{-6-1}[/tex]

∴ [tex]m=\frac{x-4}{-7}[/tex]

∵ The slope of the line is m = 1

∴ [tex]\frac{x-4}{-7}=1[/tex]

- By using cross multiplication

∴ x - 4 = -7 ⇒ add 4 to both sides

∴ x = -3

* The value of x is -3

the value of x for the point on the line is -3.

The student is asking how to find the value of x for a point on a line with a given slope. Since the slope of the line is 1, we can use the slope formula, which is (y2 - y1) / (x2 - x1) = slope, to find the value of x. Here, we have two points, (4, 1) and (x, -6), and a slope of 1.

Using the formula, we get (-6 - 1) / (x - 4) = 1. Simplifying, we get -7 / (x - 4) = 1. To find the value of x, we solve the equation -7 = x - 4, which gives us x = -3. So, the value of x for the point on the line is -3.

The equation that can be used to find the volume of the cylinder is V = π(4.5)²h (option C).

The equation that can be used to find the volume of the cylinder is V = π(4.5)²h (option C). To find the volume of a cylinder, you need to use the formula V = πr²h, where r is the radius of the base and h is the height of the cylinder. In this case, the radius is 4.5 cm and the height is not given, so it is represented as h. By substituting the values into the formula, you get V = π(4.5)²h.

The formula for finding the circumference of the circle is 2 pi r or pi d. R stand for radius and D stand for diameter. The problem gave you the length of the diameter so can either put it in form of pi as in 30pi or multiply it by pi (3.14) which will give you the result of 94.2

Given step 1

324π = π × 12² h

Then second step should read

324π = π × 144h ← 144 not 24 is the error

Answer:

6 inches

Step-by-step explanation:

area of triangle = 1/2 b* h

24 = 1/2 * 8* h

4h = 24

divide both sides by 4

h = 6 inches

Area is 1/2 x base x height.

24 = 1/2 x 8 x H

Multiply both sides by 2:

48 = 8 x Height

Divide both sides by 8:

Height = 48 / 8

Height = 6 inches.

The total cost of 1 pair of pants and 1 shirt is $18 . If s represents the cost of 1 shirt, which equation could you use to find .

For this case we propose a system of equations:

p: Variable representing the cost of a pair of pants

s: Variable representing the cost of a shirt

A pair of pants costs twice as much as a shirt, means:

[tex]p = 2s[/tex]

The total cost of 1 pair of pants and 1 shirt is $ 18:

[tex]p + s = 18[/tex]

We substitute the first equation in the second:

[tex]2s + s = 18\\3s = 18\\s = \frac {18} {3}\\s = 6[/tex]

The following equation can be used:

[tex]2s + s = 18[/tex]

Check the picture below.

let's notice that the angle at K is an inscribed angle with an intercepted arc

[tex]\bf \stackrel{\textit{using the inscribed angle theorem}}{K=\cfrac{\widehat{LI}+\widehat{IJ}}{2}}\implies 9x+1=\cfrac{(10x-1)+59}{2} \\\\\\ 9x+1=\cfrac{10x+58}{2}\implies 18x+2=10x+58\implies 8x+2=58 \\\\\\ 8x=56\implies x=\cfrac{56}{8}\implies x=7 \\\\[-0.35em] ~\dotfill\\\\ K=9x+1\implies K=9(7)+1\implies \boxed{K=64}[/tex]

now, let's notice something again, the angle at L is also an inscribed angle, intercepting and arc of 97 + 59 = 156, so then, by the inscribed angle theorem,

∡L is half that, or 78°.

now, let's take a look at the picture down below, to the inscribed quadrilateral conjecture, since ∡J and ∡I are both supplementary angles, then

∡I = 180 - 64 = 116°.

∡J = 180 - 78 = 102°.

The measure of all the angle of KLIJ which is inscribed in circle k(O) are, 64, 78, 116, 102 degrees.

Inscribed angle theorem is the theorem, which state that the angle inscribed in a circle will be half of the angle which delimits the same arc on the circle.

The quadrilateral KLIJ is inscribed in circle k(O). In this the measure of the angle are given as,

[tex]m\angle K = (9x+1)^o[/tex]

m (arc) LI = (10x−1)°

m (arc) IJ = 59°,

m (arc) KJ =97°

All angles of the quadrilateral KLIJ has to be found out. By the inscribed angle theorem,

[tex]K=\dfrac{LI+IJ}{2}\\9x+1=\dfrac {10x-1+59}{2}\\18x+2=10x+58\\8x=56\\x=7[/tex]

Therefore, the value of the angle k is,

[tex]m\angle K = (9(7)+1)^o\\m\angle K = 64^o[/tex]

Similarly, the measure of the angle L is,

[tex]m\angle L=\dfrac{KJ+IJ}{2}\\m\angle L=\dfrac {97+59}{2}\\m\angle L=\dfrac{156}{2}\\m\angle L=78^o[/tex]

Now the angles I and J are the supplementary angles of the angle K and angle L respectively. Therefore,

[tex]m\angle I=180-m\angle K=180-64=116^o\\ m\angle J=180-m\angle L=180-78=102^o[/tex]

Hence, the measure of all the angle of KLIJ which is inscribed in circle k(O) are, 64, 78, 116, 102 degrees.

Answer:

x < - 1

Step-by-step explanation:

Given

5x + 8 < 3(x + 2) ← distribute

5x + 8 < 3x + 6 ( subtract 3x from both sides )

2x + 8 < 6 ( subtract 8 from both sides )

2x < - 2 ( divide both sides by 2 )

x < - 1

The inequality 5x + 8 < 3(x + 2) simplifies to x < -1.

To solve the inequality 5x + 8 < 3(x + 2), we must simplify and isolate the variable x. We start by distributing the 3 on the right side:

5x + 8 < 3x + 6

Next, we'll subtract 3x from both sides to get:

2x + 8 < 6

Now subtract 8 from both sides to isolate the term with x:

2x < -2

Finally, we divide both sides by 2:

x < -1

The solution to the inequality is all x-values that are less than -1.

Since we can see from the scatter plot that it has negative correlation.

Equation for the line of best fit is given by

f(x)=-4.28402x+0.0875

f(x) = x³ – 2x² – x + 2

 0 = x3 – 2x2 – x + 2

 (x-2)(x-1)(x+1)=0

 x3=2

For this case we must follow the steps below:

We factor the polynomial, starting by factoring the maximum common denominator of each group:

[tex]x ^ 2 (x-2) - (x-2)[/tex]

We factor the maximum common denominator[tex](x-2):[/tex]

[tex](x-2) (x ^ 2-1)[/tex]

Now, by definition of perfect squares we have:

[tex]a ^ 2-b ^ 2 = (a + b) (a-b)[/tex]

Where:

Answer:

The answer is .800

To round .796 to the nearest hundredth, we observe the third decimal place (6) and round up the second decimal place from 9 to 10, which effectively turns .796 into .80.

The question asks us to round .796 to the nearest hundredth. To do this, we look at the third decimal place, which is 6. Since 6 is greater than 5, we round up the second decimal place from 9 to 10. However, since the second place cannot literally take the value of 10, it effectively rolls over and adds 1 to the first decimal place, changing .796 to .80. Therefore, the answer is .80 when rounded to the nearest hundredth.
