What is the constant of variation for the quadratic variation?x 2 3 4 5 6
y 20 45 80 125 180
A.5
B.10
C.15
D.25

Answers

Given:
x  =   2     3     4      5     6
y  = 20 ; 45 ; 80; 125;180

The constant variation for the quadratic variation is 5.

y = 5x²
y = 5(2²) = 5(4) = 20
y = 5(3²) = 5(9) = 45
y = 5(4²) = 5(16) = 80
y = 5(5²) = 5(25) = 125
y = 5(6²) = 5(36) = 180

The standard form of a linear equation is ax by = c. if b = 0 and a and c are positive, which best describes the graph of this equation? the graph is a vertical line. the graph is a horizontal line. the graph is a line with a positive slope. the graph is a line with a negative slope.

Answers

I think the correct answer from the choices listed above is the first option. The standard form of a linear equation is ax + by = c. If b = 0 and a and c are positive, then the graph is a vertical line which will be equal to c/a. Hope this answers the question. Have a nice day.

A pool company claims that for optimal results customers should use 20 cups of 73% chlorine solution to treat their pools unfortunately the company only has an 80% chlorine solution and a 60% chlorine solution In stock how many cups of Each chlorine solution should be mixed to create the optimal solution?

Answers

Answer:

13 cups of the 80% chlorine solution + 7 cups of the 60% chlorine solution

Step-by-step explanation:

The pool company recommendation is 20 cups of 73% chlorine to treat their pool

Concentration of chlorine solution in stock = 80% and 60%

Therefore to make 20 cups of 73% solution, we require;

X cups of the 80% chlorine solution and

Y cups of the 60% chlorine solution

That gives 0.8·X + 06·Y = 0.73 × 20

X + Y = 20

Solving gives X = 13 cups

and Y = 7 cups

Therefore to  make the optimal solution, 13 cups of the 80% chlorine solution should be mixed with 7 cups of the 60% chlorine solution.
