As a private contractor for a septic tank cleanup company, you oversee the draining of septic tanks in the county. Your company uses a truck with a storage tank capable of holding 30,500 gallons of waste.
Is there enough storage in the truck to drain a full septic tank in the shape of a cube measuring 191 inches on each
side? (231 cubic inches in 1 gallon.)A. There is enough storage in the truck. The volume of the septic tank is about 25,219 gallons.
B. There is enough storage in the truck. The volume of the septic tank is about 30,164 gallons.
C..There is not enough storage in the truck. The volume of the septic tank is about 36,481 gallons.
D. There is not enough storage in the truck. The volume of the septic tank is about 6,967,871 gallons.
E. There is not enough storage in the truck. The volume of the septic tank is about 7,045,500 gallons.

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.

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
