Answer:
38 minutes
Step-by-step explanation:
Yards covered in a minute = 4850/20 = 242.5
Time needed to cover 9215 yards = 9215/242.5 = 38 min
<u>Given</u>:
Given that the diameter of the circle is 10 kilometers.
We need to determine the area of the circle.
<u>Radius of the circle:</u>
The radius of the circle can be determined using the formula,

Substituting d = 10, we get;


Thus, the radius of the circle is 5 kilometers.
<u>Area of the circle:</u>
The area of the circle can be determined using the formula,

Substituting r = 5, we get;



Thus, the area of the circle is 78.5 square kilometers.
Answer:
The result is
x + b/2a= ±√[(b² - 4ac)/2a]
Step-by-step explanation:
In the derivation of the quadratic formula by completing the square, the equation is created by forming a perfect square trinomial
ax² + bx + c = 0
x² + (b/a)x + c/a = 0
x² + 2(b/2a)x + b²/4a² - b²/4a² + c/a = 0
(x + b/2a)² - b²/4a² + c/a = 0
(x + b/2a)² = b²/4a² - c/a
(x + b/2a)² = (b² - 4ac)/2a
Apply square roots to both sides
x + b/2a= ±√[(b² - 4ac)/2a]
So, 420 is the smallest positive integer with 4 prime factorizations in the E-zone.
