Write as a unit rate: $12 for 5 boxes of cereal Be sure to label your answer. *

Step-by-step explanation:

A unite rate is a rate at which the quantity of something is set at one unit. We can write $12 for 5 boxes as:

To write that as a unit rate, we'll have to divide that fraction by :

÷

Label the answer above by providing the unit next to the number.

To check your work, you can multiply by to see if it will equal 12.

And of course, multiplied by will be 5:

And we're back with what we've started with, therefore our solution is correct!

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

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
