A hot air balloon ascended to a height of 35 meters 2 minutes after launch. After some time, the balloon's altitude began to change by −3 1/4 meters every minute for 9 minutes. To avoid a tree, the hot air balloon flew up by 5 1/2 meters. What is the new altitude of the hot air balloon? I’m super confused! Please helpp.

Its called a blobfish

Step-by-step explanation:

Blobfishes are known to be one of the few animals that are pink (and as ugly). But it's not always like that. In its normal habitat, which is 2,000 to 4,000 feet underwater, the pressure there makes it look like any ordinary fish. But as it is brought up to the surface, caught in fishermen's trawling nets, the pressure of the water decreases and the blobfish begins to lose its shape. A you may know, deep sea fish have to survive a lot of pressure. There are many other fish that can change shape or even die if they get to close to the surface. Also, this fish is called Psychrolutes marcidus. It inhabits the deep waters off the coasts of mainland Australia and Tasmania, as well as the waters of New Zealand.

I hope you enjoy your new background!
