In the figure below, BL, AM, and CK are medians of △ABC. If KC = 108 and OC = 2n + 10, then n=

The picture is attached below.

The value of n is 31.

The median is the line connecting the vertex and its midpoint on the opposite side of the triangle.

The intersection of all 3 medians of the triangle is called the centroid.

As we know centroid divides the median in the ratio of 2:1.

In the given picture,

Medians of triangle △ABC are AM, BL, and CK.

So the centroid of the triangle is O.

Given that KC= 108

As the centroid O divides the line KC in 2:1.

Let OC=2x

KO= X

As KC= KO+OC

⇒ 108= x+2x

⇒ 3x=108

⇒ x=108/3

⇒ x=36

Then OC= 2x= 2*36= 72

As given in the question OC= 2n+10

putting the value of OC in above equation

⇒ 72= 2n+10

⇒ 2n= 72-10

⇒ 2n=62

⇒ n=62/2

⇒n=31

Therefore the value of n is 31.

The appropriate values are; [tex]sin \theta = \frac{3\sqrt{10} }{10 }[/tex], [tex]cos\theta = -\frac{\sqrt{10} }{10}[/tex], [tex]cot\theta= -\frac{1}{3}[/tex], [tex]sec\theta=-\sqrt{10}[/tex] and [tex]csc\theta= \frac{\sqrt{10} }{3}[/tex].

Given the equation and interval.

tanθ = -3, [ π/2 < θ < π ]

First, we use the definition of tangent to determine the known sides of the unit circle right triangle.

Note that; the quadrant determines the sign of each values.

tanθ = opposite / hypotenuse

We can use Pythagoras theorem to find the hypotenuse of the unit circle right triangle as the opposite and adjacent sides are known.

Hypotenuse = √( opposite² + adjacent² )

Hence, we have;

Hypotenuse = √( [3]² + [-1]² )

Hypotenuse = √( 9 + 1 )

Hypotenuse = √10

1) To find sinθ

sinθ = opposite / hypotenuse

sinθ = 3/√10

We simplify

sinθ = 3/√10 × √10/√10

sinθ = 3√10 / 10

[tex]sin \theta = \frac{3\sqrt{10} }{10 }[/tex]

2) cosθ

cosθ = adjacent / hypotenuse

cosθ = -1 / √10

Simplify

cosθ = -1 / √10 × √10/√10

cosθ = -√10 / 10

[tex]cos\theta = -\frac{\sqrt{10} }{10}[/tex]

3) cotθ

cotθ = adjacent / opposite

cotθ = -1 / 3

[tex]cot\theta= -\frac{1}{3}[/tex]

4) secθ

secθ = hypotenuse / adjacent

secθ = √10 / -1

[tex]sec\theta=-\sqrt{10}[/tex]

5) cscθ

cscθ = hypotenuse / opposite

cscθ = √10 / 3

[tex]csc\theta= \frac{\sqrt{10} }{3}[/tex]

Therefore, the appropriate values are; [tex]sin \theta = \frac{3\sqrt{10} }{10 }[/tex], [tex]cos\theta = -\frac{\sqrt{10} }{10}[/tex], [tex]cot\theta= -\frac{1}{3}[/tex], [tex]sec\theta=-\sqrt{10}[/tex] and [tex]csc\theta= \frac{\sqrt{10} }{3}[/tex].

Answer:

22.6

Step-by-step explanation:

a^2 + b^2 = c^2  We know one of the legs and the hypotenuse.  The hypotenuse must be c.  The leg that we do know can be a or b.  It is our choice.  I am going to let it be a

8^2 + b^2 = 24^2  Plug in the numbers that I know

64 + b^2 = 576   Square the numbers that I know

b^2 = 512   Subtract 64 from both sides

b = 22.6  Put this in your calculator to find the square root and round.

Using proportions, it is found that:

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The unit price is given by the cost divided by the number of ounces, and the better deal is given by the deal with the lowest unit price.

Hence, for the 11.3 ounce package:

u = 3.68/11.3 = $0.33 per ounce.

For the 29.3 ounce package:

u = 8.98/29.3 = $0.31 per ounce.

Due to the lower unit cost, the 29.3 ounce package is the better deal.

Adam's weekly money deposit is a linear relation with a slope of $6 per week.

A) Money deposited by Adam each week is $6.

B) The answer can be determined by observing the graph provided to us, in which the point representing 1 week on the x-axis is intersected by the point representing $6 on the y-axis. This helps us determine that Adam's weekly deposit is $6.

C) An alternative strategy of calculating the slope can be used.

The slope can be calculated in the following way:

m = (y₂ - y₁)/(x₂ - x₁), where (x₁, y₁) and (x₂, y₂) are two points on the line.

Thus slope of this line can be calculated as,

m = (12 - 6)/(2 - 1) = 6/1 = 6 {Since, the line passes through the points (2, 12) and (1, 6)}.
