Answer:

2√61/19

Step-by-step explanation:

sin^2 x = 1 - cos^2 x

            =  1 - (3√13/ 19)^2

             =   1 - 117/361

              =  244/361

sin x       = √244/19

              = 2√61/19.

Step-by-step explanation:

     7x - 8 = 20

⇔ 7x - 8 + 8 = 20 + 8

⇔ 7x = 28

Answer:

2 tons and 1824 pounds

Step-by-step explanation:

Ton= 2,000 pounds

We know that 2,000 will go into 5824 twice, resulting in 4,000. Subtract 4,000 from 5,284, and you will have an answer of 1284. 1,284 does not go into a ton, therefore you have a remainder of 1,284 pounds.

The coordinate of the point C from the given triangle ABC after translation is C' = (4, -2)

A triangle is a 2D figure with 3 sides and angles. Given the coordinate C points of the triangle;

C = (-2, -3)

If these coordinate point is translated 6 units to the right and 1 units up, the resulting coordinate will be at:

C' = (-2 + 6, -3 + 1)

C' = (4, -2)

Hence the coordinate of the point C from the given triangle ABC after translation is C' = (4, -2)

Step-by-step explanation:

The graph will start repeating after every 13 degrees

The period of the function is of 12 units.

The period of the function is the interval between repetitions of any function. A trigonometric function's period is the length of one whole cycle. As a starting point, we can use x = 0 for any trigonometry graph function.

The period of a function is given by the distance between it's repetitions.

Also, it is the distance between two peak value.

Looking at the graph, the distance between the repetitions is of

= 13- 1

= 12 units, which is the period of the function.

The equation representing the given case is 2(x - 8) = 3(x + 3), where x is the number.

The number satisfying this equation is -25.

In the question, we are asked to find the number when twice the difference of the number and 8 is equal to thrice the sum of the number and 3.

We assume the number to be x.

The expression representing twice the difference between the number and 8, can be shown as 2(x - 8).

The expression representing thrice the sum of the number and 3, can be shown as 3(x + 3).

We are informed that these two expressions are equal. This can be shown as the equation:

2(x - 8) = 3(x + 3).

Thus, the equation representing the given case is 2(x - 8) = 3(x + 3), where x is the number.

Now, to find the number, we solve the equation as follows:

2(x - 8) = 3(x + 3),

or, 2x - 16 = 3x + 9 {Simplifying},

or, 2x - 16 + (16 - 3x) = 3x + 9 + (16 - 3x) {Adding (16 - 3x) to both sides of the equation},

or, 2x - 16 + 16 - 3x = 3x + 9 + 16 - 3x {Simplifying},

or, -x = 25 {Simplifying},

or, -x(-1) = 25(-1) {Multiplying both sides of the equation with -1},

or, x = -25 {Simplifying}.

Thus, the number satisfying the equation is -25.

Here, we are concerned about two variables from the above data set, namely, Condo or co-ops and the Unemployment rate. We use the CORREL function of Excel to calculate the correlation coefficient rate and it is = R = -0.01873.

A Weak (negative) correlation exists between the list price of condominiums and co-ops and the unemployment rate.

The correlation coefficient is a statistical measure of the strength of the connection between the relative actions of two variables. The values varied between -1.0 and 1. zero. A calculated wide variety greater than 1. zero or less than -1.zero means that there was an error within the correlation size.

The correlation coefficient is decided with the aid of dividing the covariance by way of the product of the 2 variables' popular deviations.

Correlation values above 0. eight are deemed to signify a strong tremendous linear courting between the variables. Values among zero and 0. three imply a vulnerable relationship or none.

Answer:

1.6

Step-by-step explanation:

To find the constant of proportionality, we do [tex]\frac{x}{y}[/tex]. We see that 2/1.25=1.6, 4/2.5=1.6, 6/3.75=1.6, and 10/6.25=1.6. This means that the constant of proportionality is equal to 1.6.

The area of ​​the trapezoid is x+11 cm.

Given a trapezoid has one side of (x+6) cm, the other side is 5 cm, and the height is 2 cm.

A two-dimensional quadrilateral consisting of the sum of non-adjacent parallel sides and a suitable non-parallel side is denoted as a trapezoid.

Now we will use the formula to find the area of ​​a trapezoid

Area = 1/2 × (base 1 + base 2) × height

Here base 1 = (x+6) cm, base 2 = 5cm and height = 2cm

Substituting the values ​​into the formula,  we get

Area = 1/2 × (x+6+5) × 2

Area = 1/2 × (x+11) × 2

Area = x+11

Thus, the area of ​​the given figure when one side is x+6, the other side is 5 cm and the height is 2 cm is x+11 cm.

We can see that the base price for a canoe is $12, as you have to spend the $12 to get the canoe.

You also have to spend $5 per hour in the canoe, which is why "t" is being multiplied by 5.

We can also look at this graphically.

The x-axis is the number of hours, while the y-axis is the price. When x is 0 (no hours on canoe), you can see that the price is $12. But as it increases by 1 hour, the price increases by $5.
