No, 1 is not a composite number because it needs one positive factor other than 1 and itself
Answer:
The area of the park is equal to 2,500 square meters.
Step-by-step explanation:
Given that a man runs around a square park and covers 1km in five rounds, the following calculation must be performed to determine the area of the park:
Assuming that the park was square in shape, to calculate its area its base must be multiplied by its height (which are equal).
Thus, if in 5 laps the man runs 1 km, for each lap he will run 200 meters (1000/5). Thus, dividing 200 by the 4 sides of the square, we get 50 meters (200/4). Therefore, since 50 x 50 is equal to 2,500, the area of the park is equal to 2,500 square meters.
Answer:
x < 0
Step-by-step explanation:
If you were to graph the function, you would get a parabola that opens down with the vertex at (0, 0). So, the graph is increasing from -∞ to 0.
Answer:
Divide by 1,000
Step-by-step explanation:
To get down from each level in the metric system, you need to divide by ten, Millimeters are 3 steps down from meters so you need to divide by 1000.
Answer:
3x³ + 12x² - 7x - 28
Step-by-step explanation:
(f • g)(x) = f(x) × g(x)
= (x + 4)(3x² - 7)
Each term in the second factor is multiplied by each term in the first factor, that is
x(3x² - 7) + 4(3x² - 7 ) ← distribute both parenthesis
= 3x³ - 7x + 12x² - 28
= 3x³ + 12x² - 7x - 28
