Brainliest! Rock is thrown upward from top of 112-foot high cliff overlooking ocean at speed of 96 feet per second. The rocks height above can be modeled by f(x)= -2t^2 + 92t - 480

256 feet

Step-by-step explanation:

Answer from: mfin11

40 seconds

Step-by-step explanation:

Find the value of t, when the value of f(x) is zero, assuming the ocean level is zero point.

Solve the equation:

-2t² + 92t - 480 = 0t² - 46t + 240 = 0t² - 40t - 6t + 240 = 0t(t - 40) - 6(t - 40) = 0(t - 6)(t - 40) = 0t = 6, t = 40

The first root is not to be considered, as the rock was thrown from the positive height, not negative.

"it's not the heat, it's the humidity". that's a partly valid phrase you may have heard in the summer, but it's actually both. the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature. this has important considerations for the human body's comfort. when the body gets too hot, it begins to perspire or sweat to cool itself off. if the perspiration is not able to evaporate, the body cannot regulate its temperature. evaporation is a cooling process. when perspiration is evaporated off the body, it effectively reduces the body's temperature. when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases. in other words, the human body feels warmer in humid conditions. the opposite is true when the relative humidity decreases because the rate of perspiration increases. the body actually feels cooler in arid conditions. there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).

75% of the temperatures are below what value? how do you know? 75% of the temperatures are above w
