For this case we have the following function:
To find the zeros of the function we make and solve for "x", then:
We multiply by -1 on both sides of the equation:
We factor the equation, for this we look for two numbers that, when multiplied, result in 36 and when added, result in -13. These numbers are -9 and -4.
Thus, the factored equation is:
Therefore, the roots are:
Answer:
Answer:
50.24 ft^2
Step-by-step explanation:
The radius of the circle in which the lawn sprinkler sprays water is 4 feet.
The formula to find the area of a circle is , where r = radius and π, in this case, is 3.14.
- 3.14 × 4^2
- 3.14 × 16
- 50.24 ft^2
Therefore, the answer is 50.24 ft².
