A geyser sends a blast of boiling water high into the air. During the eruption, the height h (in feet) of the water t
seconds after being forced out from the ground can be modeled by h(t) = –16t2 + 70t. What is the maximum height of
the boiling water? (round to the nearest tenth)

Im literally having a mental breakdown

Sandy is upgrading her internet service. fast internet charges $20 for installation and $52.45 per month. quick internet has free installation but charges $57.45 per month. part 1 out of 2 complete the equation that can be used to find the number of months after which the internet service would cost the same. use the variable x to represent the number of months of internet service purchased.

Find the value of x to the nearest tenth. a. 4.5 b. 5.4 c. 6.3 d. 7.2
