Mario is filling a fish tank with water at a rate of 1 gallon every 30 seconds. Which graph shows the relationship between the number of gallons in the tank and time in minutes?

i used to know how to do this in 7th but i forget easily

step-by-step explanation:

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

make sure you have version 2.50

try looking in the very back of the book : )
