Answer:

Step-by-step explanation:

Median of triangle: It is a line segment joining a vertex to the midpoint of the opposite side.

Consider ΔABC, point F id the midpoint of line segment AB and E is the midpoint of luine segment AC.

Draw line segments FC and BE(medians of triangle). G is the point where line segment FC and BE meet. Now, Join AG.

Let H be the point outside the ΔABC and AG passs through the point H such that AG intersects BC at D. BH and HC are dashed lines.

We need to show that D is the midpoint of BC. The correct logical order for proof will be:

III. GC is parallel to line segment BH and line segment BG is parallel to line segment HC.

IV. Line segment FG is parallel to line segment BH and line segment GE is parallel to line segment HC.

I. BGCH is a parallelogram as opposite sides are parallel (from III.)

II. Since, diagnols of a parallelogram bisect each other. Henc, we get BD=DC.

Therefore, D is mid pont of BC.

It implies that AD is also a median.

Hence, all the three medians that are: BE,FC and AD passes through a common vertex G.

How does the graph of f(x) = (x – 8)^3 + 4 compare to the parent function g(x) = x^3?

Ludmilka [50]

Answer:

Therefore, the graph of f(x) = (x – 8)^3 + 4, is the parent graph [g(x) = x^3] transformed 8 units to the right, and transformed 4 units up

Step-by-step explanation:

Recall,

If f(x) is a parent function:

• Horizontal shift: If h is the horizontal shift then f(x+h)) represents a graph which is formed when the parent graph is transformed to left (when h>0) or to right (when h<0))

• Vertical shift: If h is the vertical shift then f(x)+h represents a graph which is formed when the parent graph is transformed to up(when h>0) or to down (when h<0).

Therefore, the graph of f(x) = (x – 8)^3 + 4, is the parent graph transformed 8 units to the right, and transformed 4 units up.

Ms.Friedman and Mrs.Elliot both teach sixth grade math. They share a storage closet. What is the total area of both rooms and th

Citrus2011 [14]

Answer:
Total area of both rooms and the storage = 2844 ft^2

Explanation:
Total area would initially be the summation of the area of Ms. Friedman's room and storage added to Mrs. Elliot's room and storage.
However, we are given that the storage is shared.
So now, the total area would be equal to Ms. Friedman's room and storage + Mrs. Elliot's room and storage - area of closet

Now, we can notice that:
Ms. Friedman's room and storage = Mrs. Elliot's room and storage

Therefore:
Total area = 2*Ms. Friedman's room and storage - area of storage

1- getting area of Ms. Friedman's room and storage:
length = 36 ft
width = 40 ft
area of Ms. Friedman's room and storage = length * width
area of Ms. Friedman's room and storage = 36 * 40
area of Ms. Friedman's room and storage = 1440 ft^2

2- getting area of closet:
length = 36 - 30 = 6 ft
width = 40 - 34 = 6 ft
area of closet = length * width
area of closet = 6 * 6 = 36 ft^2

3- total area of both rooms and the storage:
Total area = 2*Ms. Friedman's room and storage - area of storage
Total area = 2*1440 - 36
Total area = 2844 ft^2

Hope this helps :)

If 64x=82, what is the value of x?<br> Round your answer to three places.

labwork [276]

Answer:

1.28

Step-by-step explanation:

First, you need to do 82/64, which will give you just x. Then, you need to round to three places. Without rounding it would be 1.28125

So with rounding it would be 1.28. Hope this helps and Happy learning!

An inequality for x is less than 12

mixer [17]

Answer:

x < 12

Step-by-step explanation:

Note that the symbol for:

"less than" is <

"greater than" is >

"less than or equal to" is ≤

"greater than or equal to" is ≥

In this case, the question states that the variable "x" is less than 12. Set the equation: x < 12

x < 12 is your answer.

Dida bought a scratch ticket for $2.00. The potential payoffs and probability of those payoffs are shown below.

kakasveta [241]

9514 1404 393

Answer:

(b) $1.15

Step-by-step explanation:

The expected value is the sum of products of payoff and probability:

$0×0.15 +0.50×0.5 +1.0×0.2 +2.0×0.1 +10×0.05

= $0 +0.25 +0.20 +0.20 +0.50

= $1.15 . . . . expected value of the scratch ticket
