Answer:
B) Chemical Change
Step-by-step explanation:
Physical change only changes the physical appearance of good, their chemical properties remaining same. These are usually reversible. Eg : Cutting a cake
Chemical change changes the physical composition of the product(s) involved. These are usually not irreversible. Eg : Baking of a cake, getting bubbles during bake process meanwhile
Answer:
hi, can you please answer mine too it's just a 1 question I really need the answer because I have to pass it later at 10 pm and it's already 9:01pm I hope you can help me:(
Step-by-step explanation:
about your question I'll just put it in the comment section:)
P(x) that will be R(x) - C(x):
Note the use of parentheses! Without them we would not realize that both the 21 and the 98 should be subtracted.
Now that we have our profit function, we can see that:<span>Its graph will be a parabola because of the squared term.The parabola will open downward because of the negative coefficient, -2, in front of the squared term.The highest point (which would be the maximum profit) on the downward parabola would be the vertex of the parabola.</span>From the above we now know that we want to find the vertex of the profit parabola.
The x coordinate of the vertex of a parabola will be -b/2a where the "b" is the coefficient of the x term and the "a" is the coefficient of the x squared term. From p(x)= -2^2 + 34x-98
we can see that your "a" is -2 and your "b" is 34. So the x coordinate of the vertex (which is where the maximum profit is) will be: -34/-2=17
Answer:
80%
Step-by-step explanation:
1/8 is only 0.125 and 80% is 0.8
Answer:
4/3
Step-by-step explanation:
y=mx+b
and B is y-intercept
m is the slop which is (y2-y1)/(x2-x1)
so m= (4-0)/(0+3)=4/3 that is the slop
