Counterclockwise rotation about the origin by 180 degrees, followed by a reflection over the y-axis.
The second chloce.
Answer:
10 rounds.
Step-by-step explanation:
Let x represent number of rounds around the field.
We have been given that the distance around our playing field is 300 meters long. So distance covered in x rounds would be meters.
We are also told that your coach wants you to run 3 kilometers. Let us convert 3 km in meters.
1 km = 1000 m
3 km = 3*1000 m = 3000 m
Now, we will equate total distance covered in x rounds by 3000 as:
Therefore, you need to run 10 times around the field.
Answer:
70x³ - 73x² - 155x + 168
Step-by-step explanation:
Given
(5x - 7)(2x + 3)(7x - 8) ← expand the first pair of factors using FOIL
= (10x² + x - 21)(7x - 8)
Each term in the second factor is multiplied by each term in the first factor, that is
10x² (7x - 8) + x(7x - 8) - 21(7x - 8) ← distribute the 3 parenthesis
= 70x³ - 80x² + 7x² - 8x - 147x + 168 ← collect like terms
= 70x³ - 73x² - 155x + 168
