<span>Solutions or Roots of Quadratic Equations. A real number x will be called a solution or a root if it satisfies the equation, meaning . It is easy to see that the roots
are exactly the x-intercepts of the quadratic function , that is the
intersection between the graph of the quadratic function with the
x-axis.</span>
Answer:
3 rows/hour
Step-by-step explanation:
It is given that, Jose takes 120 minutes to weed 6 equal rows of vegetable plants in his garden.
120 minutes = 2 hours
We need to find the unit rate per hour for weeding these rows of his garden. It can be calculated as follows :
So, the rate for weeding these rows of his garden is 3 rows per hour.
Isiah is 5.83 miles away from his starting point.
When you draw the the miles Isaiah walks, you will discover that you are forming a right angle triangle.
To measure the length from the starting point to the ending point. We must used the Pythagorean equation. Where in the square of the hypotenuse is equal to the sum of squares of the other two sides.
a² + b² = c²
a = 3 miles 3² + 5² = c²
b = 5 miles 9 + 25 = c²
c = hypotenuse. 34 = c²
We must get the hypotenuse, since 34 is the square of the hypotenuse we must look for its square root.
c² = 34
c = √34
c = 5.83 miles
