In triangle IJK , O is the intersection of the three medians . If IN = 12 find IK. please help
Answer:
IK = 24
Step-by-step explanation:
Since is says that O is the point of intersection of the three medians (also known as centroid) the segment JN which passes through a vertex of the triangle, would have to be a median to segment IK.
Medians divide a segment into two congruent parts, so IN = NK = 12 as we are given IN = 12.
IK is the sum of the measure of IN and NK, so in other words:
IK = IN + NK = 12 + 12 = 24

Sides of three square rooms measure 13 feet each, and sides of two square rooms measure 15 feet each. Which expression shows the total area of
these five rooms?
A fraction is a fragment of a whole number, used to define parts of a whole. The whole can be a whole object, or many different objects. The number at the top of the line is called the numerator, whereas the bottom is called the denominator.
We know that a square has 4 sides of the same length, meaning that the length and the width are the same length. You can solve for the area of the first three rooms with a length of 13 feet using an equation like this:
(13 × 13) × 3
Now, for the other two rooms with the length of 15 feet:
(15 × 15) × 2
Simply add them together.
([13 × 13] × 3) + ([15 × 15] × 2)
Simplified, the expression would look like this:
(169 × 3) + (225 × 2) = 957
Therefore, the expression that shows the total area of these five rooms would look like this: ([13 × 13] × 3) + ([15 × 15] × 2), or it being simplified would look like this: (169 × 3) + (225 × 2) = 957

If f(x) = 8 – 10x and g(x) = 5x + 4, what is the value of (fg)(–2)?
Answer:
(fg)(-2) = 18
Step-by-step explanation:
f(x) = 8 – 10x
g(x) = 5x + 4
To find (fg)(-2) or f(g(-2)), first let's find g(-2) by subbing -2 in for x in g(x):
g(x) = 5x +4
g(-2) = 5(-1) +4 = -5+4 = -1
Knowing g(-2)=-1, we can now find f(g(-2)) by subbing -1 in for x in f(x):
f(x) = 8 – 10x
f(-1) = 8 - 10(-1) = 8+10 =18

1. How many faces, vertices, and edges do the pyramids have? Name at least
three patterns you notice.
Pyramid have faces=n triangles & 1 n-sided polygon
Edges=2n
vertices=n + 1
What are edges?An edge is a line segment that serves as a transition between two faces. It is also sometimes referred to as the line segment that connects two vertices.
What are vertices?The location where two or more edges intersect is the formal definition of the vertex in mathematics. The corner points are called vertices.
What are faces?A solid's face refers to each unique flat surface. Solids have multiple faces.
The number of faces in a pyramid is equal to one more than the base's polygon's number of sides.
faces = n triangles & 1 n-sided polygon
One more than the number of sides at the base of the polygon makes up the number of vertices in a pyramid.
hence, vertices = n + 1
Two times the number of sides at the base of a polygon equals the number of edges on a pyramid.
Therefore, edges = 2n
A pyramid has n triangles & 1 n-sided polygon Faces
A pyramid has 2n Edges.
A pyramid has n + 1 Vertices.

Sum of interior angles in Polygon:A polygon is a geometric object with two dimensions and a finite number of sides. A polygon's sides are made up of segments of straight lines that are joined end to end. As a result, a polygon's line segments are referred to as its sides or edges.
The geometric shape known as a pentagon has five sides and five angles. Penta here means five, and gon means angle. One of the different kinds of polygons is the pentagon. A regular pentagon's internal angles add up to 540°.
Here we have a five-sided Polygon
And the angles are 127°, 112°, 108°, 120°, and x°
As we know the sum of angles = 540°
=> 127° + 112° + 108° + 120° + x° = 540°
=> 467° + x° = 540°
=> x° = 540° - 467°
=> x° = 73°

Deena bought some shirts at the store for $9 each and received a $25 discount. Her total bill was $74. Find the number of shirts she bought
Answer:
11
Step-by-step explanation:
If we know that she paid $74, and the discount is $25, we need to figure out the total price of the shirts before the discount.
74 + 25 = 99
Now that we know she spent $99 on shirts, we can divide that by 9 to get the number of shirts purchased.
99 ÷ 9 = 11
Therefore, she bought 11 shirts.

Identify the key features of the graph of the function g(x)= log 2 (x-1)+2
The key features of the graph of the function would be
1) Domain - (1, infinity).
2) The range of the function is (2, infinity).
3) The graph of the function is a monotonically increasing function.
4) The graph of the function is asymptotic to the x-axis as it approaches x = 1.
5) The graph is a straight line, that is passing through the point (1,2) and has a slope of 1.
6) The graph is a shifted version of the function log2(x) by 2 units upward.
What is the graph of the function?
The graph of a function is a visual representation of the relationship between the inputs and outputs of the function. It is a diagram that shows the set of all possible points (x,y) that satisfy the equation of the function y = f(x) or in the case of a multivariable function y = f(x,z).
The graph of the function g(x) = log2(x-1) + 2 has several key features. Some of these features include:
1) The domain of the function is (1, infinity) since the logarithm is defined for x>0 and x-1 >0.
2) The range of the function is (2, infinity) since the minimum value of log2(x-1) + 2 is 2.
3) The graph of the function is a monotonically increasing function, meaning that as the input x gets larger, the output g(x) also increases.
4) The graph of the function is asymptotic to the x-axis as it approaches x = 1. This means that as x gets closer to 1, the graph of the function gets closer to the x-axis but never touches it.
5) The graph is a straight line, that is passing through the point (1,2) and has a slope of 1.
6) The graph is a shifted version of the function log2(x) by 2 units upward.
Hence, the key features of the graph of the function would be
