We have to know divide the total meters that has been traveled by the tortoise which is for 4.8 meters to the time it was completed which is 3 minutes. The formula for speed is: [ speed = distance/time ]. So the equation will be 4.8 meters/3 minutes = 1.6 meters per minute. The speed of the tortoise is 1.6 meters per minute.
Answer:
the greatest common factor is 6
Matrices always go row x column.
Count the rows: 4
Count the columns: 3
The matrix is a 4 x 3 matrix
Answer:
<h2>50.8°</h2>
Step-by-step explanation:
First, we need to use the Pythagorean Theorem to find the third side. We will then use the law of cosines to find the angle.
2√15² = 2√6² + b²
60 = 24 + b²
Subtract 24
36 = b²
b = 6
Now, that we have all three sides, we will use the law of cosines to figure out the angle.
c² = a² + b² - 2abCosC°
Substitute the values in.
6² = 2√15² + 2√6² - 2(2√15)(2√6)CosC°
36 = 60 + 24 - 2(37.947331922)CosC°
36 = 60 + 24 - 75.894663844CosC°
36 = 84 - 75.894663844CosC°
Subtract 84
-48 = -75.9CosC°
0.63241106719 = CosC°
Arccos (0.63241106719) = 50.77176844°
The largest acute angle is approximately 50.8°
