Liquid A and liquid B are mixed together in the ratio 3 : 11 by volume to make liquid C. Liquid A has density 1.31 g/cm3
Liquid B has density 1.12 g/cm3
A cylindrical container is filled completely with liquid C.
The cylinder has radius 4 cm and height 28 cm.
Work out the mass of the liquid in the container.
Give your answer correct to 4 significant figures.
You must show all your working.

correct answer:

i^31 = -i

i don't have the answer rn but go to math papa. it shows the steps and the answer. hope this : )

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1
