Answer:
7.0 < x < 7.6
X is the ideal pH of the swimming pool
Answer:
<u>2nd row</u>
Step-by-step explanation:
The y-intercept corresponds to the ordered pair having an x-value of 0. The second row of the table has an x-value of 0, and y-value of 2. Therefore, the y-intercept is (0, 2).
The area of the triangle is
= 3.4641 square feet.
Step-by-step explanation:
Step 1:
According to the Pythagorean theorem, the square of the hypotenuse will be equal to the sum of the squares of the other two sides.
In the given triangle, the hypotenuse is the side that is represented by c. The other sides on the triangle are represented by the values a and b.
Step 2:
Assume the other side of the triangle measures x units.
So according to the Pythagorean theorem,


So the other side of the triangle, b measures 2 feet.
Step 3:
The area of a triangle is half the product of its base length and height.
The base length of this triangle is
feet and the height is 2 feet.
The area of the triangle
The area of the triangle is
= 3.4641 square feet.
If they intersect at this point, that means this point is a solution (3,4)
