A periscope (a tube with a lens at one end used for observation, typically associated with submarines) is located 24 inches above the surface of the water. The periscope
continues to emerge from the water at a rate of 6 inches per second. Write a function
that would model this situation and determine the height of the periscope after it has
ascended for 22 seconds.

the difference between a number and 5 is -2.

step-by-step explanation:

notice that the equation you are given has -2 (negative 2) on the right side, not 2. when you subtract 5 from a number n, you are finding the difference between the number and 5.

the difference between a number and 5 is -2.

john earns $14.00 for two hours of work.

(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
