A snail is crawling straight up the glass side of an aquarium at a constant rate toward the top of the aquarium.The equation y = 0.4x + 3 can be used to represent the situation, where y is the height of the snail in centimeters from the bottom of the aquarium and x is the number of seconds that the snail has been crawling.Which statement best describes the height of the snail from the bottom of the aquarium,

A snail sits at the bottom of a 30-foot wall. Each hour it can climb three feet, but it then slips down two feet. How long does it take the snail to reach the top?

Select the correct answer.A bottlenose dolphin is 10 feet below sea level. Then it begins to dive at a rate of 9 feet per second. What is the equation of the line that represents its elevation, y, after x seconds? A. y = 9x − 10 B. y = -9x − 10 C. y = 9x + 10 D. y = -9x + 10

The speed of a common snail is about 1 mm per second. It secretes a bit of mucus that coats the ground beneath and helps it to move along. This snail we are interested in now has a problem with this secretion and so it moves one mm in the first second and in the subsequent seconds it moves only half the distance covered in the previous second. Algae, the good it cherishes, is at 3 mm distance from this snail. In how much time it will reach its food? OptionsIt will never reach its food 2.5 seconds 2.7685 seconds 3 seconds

A snail moves forward by 3 cm in 1 minute, and then moves backward in next minute by 2 cm. He repeats this cycle in his movement. To reach food at a distance of 10 cm, how much time will he need?

A stone is dropped from the top of an overhead water tank and at the same time another stone is thrown vertically upwards from the ground level with a velocity of 20 ms^-1. If the stones met exactly 2 seconds after their release, determine the height of the overhead tank.
