Answer:

( 2 , \frac{1}{2} )

Step-by-step explanation:

A(-2, 4) , B(6, -3)

\boxed{midpoint = ( \frac{x1 + x2}{2}, \frac{y1 + y2}{2})  }

Midpoint between points A and B

= ( \frac{ - 2 + 6}{2} , \frac{4 - 3}{2} )

= ( \frac{4}{2} , \frac{1}{2} )

= (2 , \frac{1}{2} )

Answer:

The midpoint between A and B is a point with coordinates (2, 0.5).

Step-by-step explanation:

The "y" coordinate of the midpoint will be equal to the sum of A's and B's y coordinates divided by 2,  and the x coordinate of the midpoint will be equal to the sum of A's and B's x coordinates divided by 2.

x coordinate of the midpoint = (6 - 2) / 2 = 4 / 2 = 2

y coordinates of the midpoint = (4 - 3) / 2 = 1 / 2 = 0.5

Therefore midpoint between A and B is a point with co0rdinates (2, 0.5).

oakwood has a mass of 2.85 kilograms and a volume of 4100 cubic centimeters. determine the density of oak in grams per cubic cen
bogdanovich [222]

Answer:

The density of oak is <u>0.695</u> grams per cubic centimeter.

Step-by-step explanation:

Given:

Oakwood has a mass of 2.85 kilograms and a volume of 4100 cubic centimeters.

Now, to find the density of oak in grams per cubic centimeter.

Mass (m) = 2.85 kilograms.

So, using conversion factor we convert into grams:

2.85\times 1000=2850\ grams.

Volume (v) = 4100 cubic centimeters.

Now, to get the density by using formula:

Density=\frac{mass}{volume} \\Density=\frac{m}{v}

Density=\frac{2850}{4100}

Density=0.695\ grams\ per\ cubic\ centimeter.

Therefore, the density of oak is 0.695 in grams per cubic centimeter.

The chart below lists the original and sale prices of items at a clothing store.
Tom [10]

Answer: C) For every original price, there is exactly one sale price.

For any function, we always have any input go to exactly one output. The original price is the input while the output is the sale price. If we had an original price of say $100, and two sale prices of $90 and $80, then the question would be "which is the true sale price?" and it would be ambiguous. This is one example of how useful it is to have one output for any input. The input in question must be in the domain.

As the table shows, we do not have any repeated original prices leading to different sale prices.
