The point t on the unit circle is ( -1/2, √3 /2 ).

The intersection of the x-axis (the horizontal number line) and the y-axis in the cartesian system divides the coordinate plane into four equal pieces. Because each of these four areas occupies a quarter of the entire coordinate plane, they are collectively referred to as quadrants.

Consider the point t = - 4π/3 on the circle.

Now, the reference angle is π / 3.

- 4π / 3 is in quadrant 2 where the value of cosine is negative and sine is positive.

Therefore, the point t(x,y) will be:

( x, y ) = ( - cos ( π / 3 ), sin ( π / 3 ) )

( x, y ) = ( - 1/ 2 , (√3 )/ 2 )

Mean x = ( 29 / 5 )

Var X= ( 199 / 5 ) - 29 =10.8,

Mean Y = 7.4, Var Y = ( 481/5 ) - 37 = 96.2 - 37 = 59.2

Now,

r = { n(∑xy ) - (∑x)(∑y) } / √ { n( ∑x²) - (∑x )² ) × [ n(∑y²) - (∑y)² ] }

r = { 5 × 289 - 29 × 37 } / √ { ( 5 ( 199 ) - (29)² ) × [ 5( 481 - ( 37 )² ] }

r = { 1445 - 1073 } / √ { ( 995 - 841 ) × [ 2405 - 1369 ] }

r = 372 / √ { ( 154 ) × [ 1036 ] }

What is breakeven amount of sugar for the two companies?

The amount of sugar that the two companies charge the same is derived at the point when the total cost of both companies are the same, bearing in mind that the total cost in this case is made of fixed cost to rent truck and variable cost, which is additional fee for each ton of sugar moved.

The inequality that can be used to determine x, the number of outfits Zendaya can purchase  is 329.92 + 65.65x <= 540

The given parameters are:

Budget = $540

New bicycle = $269.88.

4 bicycle reflectors = $10.57 each

Pair of a bike gloves = $17.76.

New biking outfits = $65.65 each.

Let the number of new biking outfits be x

So, we have

New bicycle + 4 * price of bicycle reflectors + Pair of a bike gloves + New biking outfits <= Budget

This gives

269.88 + 4  * 10.57+ 17.76 + 65.65x <= 540

This gives

329.92 + 65.65x <= 540

Solve the inequality

65.65x <= 210.08

Divide by 65.65

x <= 3.2

Hence we would conclude that If Frances left the tip of 22 percent on a meal, the cost of the meal before the tip would be 18 dollars.

Let us define x to be the cost of the meal

such that we would have

x  + 22%x =  21.96

= x + 0.22x = 21.96

1.22x = 21.96

We would have to divide through the equation that we have by 1.22

x = 21.96 / 1.22

x = 18

Step-by-step explanation:

The perimeter CDE of the triangle is solved to be 9.66 (to the nearest hundredth)

How to find the perimeter of CDE

Given data

C ( 4, -1 )

D ( 4, -5)

E ( 2, -3 )

perimeter of CDE = CD + CE + DE

length = √(x2 - x1)^2 + (y2 - y1)^2

using C ( 4, -1 ) and D ( 2, -3 )

CD = √(4 - 4)^2 + (-1+5)^2

CD = √(4)^2

CD = 4

using C ( 4, -1 ) and E ( 2, -3 )

CE = √(4 - 2)^2 + (-1+3)^2

CE = √(2)^2 + (2)^2

CE = √8

using D ( 4, -5) and E ( 2, -3 )

CD = √(4 - 2)^2 + (-5 + 3)^2

CD = √(2)^2 + (-2)^2

Answer:

x = -1

y = -2

Step-by-step explanation:

We are given the following equations:

[tex]y = -2x - 4[/tex]

[tex]y = 3x + 1[/tex]

As we can see, the expressions [tex]{-2x - 4}[/tex] and [tex]3x + 1[/tex] are both equal to [tex]y[/tex]. Therefore, we can equate them:

[tex]-2x - 4 = 3x + 1[/tex]

Now we can solve for [tex]x[/tex] by making [tex]x[/tex] the subject of the equation:

⇒ [tex]-2x - 4 -3x = 3x + 1 - 3x[/tex]      [Subtracting [tex]3x[/tex] from both sides]

⇒ [tex]-5x - 4 = 1[/tex]

⇒ [tex]-5x - 4 + 4 = 1 + 4[/tex]                 [Adding 4 to both sides of equation]

⇒ [tex]-5x = 5[/tex]

⇒ [tex]\frac{-5}{-5}x = \frac{5}{-5}[/tex]                                     [Dividing both sides by -5]

⇒ [tex]x = \bf -1[/tex]

Now that we know the value of [tex]x[/tex], we can calculate the value of [tex]y[/tex] by replacing the [tex]x[/tex] with -1 in any of the equations for  [tex]y[/tex] given above:

[tex]y = 3x + 1[/tex]

⇒ [tex]y = 3(-1) + 1[/tex]

⇒ [tex]y = -3 + 1[/tex]

⇒ [tex]y = \bf -2[/tex]

Therefore, the solution to the system of equations is : x = -1, y = -2.

Answer:

x = -1

y = -2

Step-by-step explanation:

Given system of equations:

[tex]\begin{cases}y = -2x - 4\\y= 3x + 1\end{cases}[/tex]

Use the method of substitution to solve for x:

[tex]\begin{aligned}& \textsf{Substitute}: & 3x+1 & = -2x-4\\& \textsf{Add $2x$ to both sides}: & 3x+1+2x & = -2x-4+2x\\& \textsf{Combine like terms}: & 5x+1 & = -4\\& \textsf{Subtract $1$ from both sides}: & 5x+1 -1& = -4-1\\& \textsf{Simplify}: & 5x & = -5\\& \textsf{Divide both sides by $5$}: & \dfrac{5x}{5} & = \dfrac{-5}{5}\\& \textsf{Simplify}: & x & = -1\end{aligned}[/tex]

Substitute the found value of x into one of the equations and solve for y:

[tex]\begin{aligned}& \textsf{Equation}: & y& = 3x+1\\& \textsf{Substitute in $x=-1$}: & y & = 3(-1)+1\\& \textsf{Multiply the numbers}: \quad & y & = -3+1\\& \textsf{Simplify}: & y & = -2\\\end{aligned}[/tex]
