Tony thinks his pet goldfish , finn, might be lonely. so, tony buys another goldfish to keep finn company. he also buys a large 10-gallon tank so the fish can swim together. if finn currently lives in a 2-quart fish bowls, how many times bigger is his new tank than his old bowl?

20 times bigger.

Step-by-step explanation:

A quart is a liquid unit of measurement that is equal to a quarter of a gallon. Given that, 2-quarts is equal to half of a gallon (0.5-gallon). Now, you just need to divide the volume of the new tank by the volume of the old one.

10-gallons/0.5-gallons = 20

The new tank is 20 times bigger than the old bowl.

c

step-by-step explanation:

it would be see because your formula is f(x)=6x, so 6 times 1 is 6 and you go on and the best answer is c.

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
