PLS ANSWER PLS 10 points and branliest Part 6
Pour the water from part B into one of the large containers. Pour the vinegar into the other large
container. Observe the two combinations. Pick up each container one at a time and place your palm on
the bottom to see whether you can feel a difference in temperature. Record what you see and feel.
Question Two
Explain whether a chemical reaction has occurred for each combination. Include the evidence you used to reach your conclusion.
PART B
Is this investigation a controlled experiment or an observational study? Explain your answer.
PART C
Why do you use the same amount of baking soda and same amount of liquid for each combination.

the answer is 5636.7

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

there is nothing below so i cannot
