The verticles of triangle A are (-1,3) B (7,9) and C (15,-3) Find the coordinates of the intersection of the medians.

Mathematics
1 answer:
Annette [7]3 years ago
6 0

Step-by-step explanation:

Coordinates of A≡(−1,3)

Coordinates of B≡(7,9)

Coordinates of C≡(15,-3)

The median through the vertex C will meet at the mid point of AB.

Coordinate of mid-point on AB=[(-1+7)/2 , (3+9)/2]= (3,6)

Now,

Length of median through vertex C= Distance between (15,-3) and (3,6)

Therefore,

Length of median = √(3-15)²+(6-(-3))²=√144+81=15unit

Hence the length of median through the vertx C is 15 units.

The perimeter of a rectangle is 35cm. The length is 5cm. Write and
boyakko [2]

Answer:

P = 2L + 2W

35 cm = 2(5 cm) + 2(W cm)

W = 12.5 cm

Step-by-step explanation:

P = 2L + 2W

35 cm = 2(5 cm) + 2(W cm)

35 cm - 10 cm = 2W cm

2W cm = 25 cm

w cm = 12.5 cm

Accuracy refers to A) a statement or idea that can be falsified B) how close repeated measurements of the same sample are to one
Vedmedyk [2.9K]

Answer: D) how close a measured value is to the actual value.

Step-by-step explanation: Accuracy is simply a measurement metric which is used to establish how a measured or predicted value conforms to the actual measurement usually in terms of closeness. Accuracy is different from precision which measures closeness in values obtained from repeated measurement of the same sample. For instance;

If the actual vale of a measurement is : 11.34

Prediction 1 : 11.30

Prediction 2 : 11.32 ;

Prediction 2 will be said to be more accurate than prediction 1 becuase it is closer to the actual value than prediction 1.
