An object is launched into the air. The projectile motion of the object can be modeled using the function h(t) = –16t2 + 72t + 5, where t is the time in seconds since the launch and h(t) represents the height in feet of the object after t seconds. What is true about the projectile motion of this object? Check all that apply. The initial height is 5 feet. The initial velocity of the object is –72 feet/second. The object will hit the ground after approximately 4.57 seconds. After 3 seconds, the object is 173 feet high. At t = 0, h(t) = 0.

A real estate office manages an apartment complex with 50 units. When the rent is $780 per month, all 50 units are occupied. However, when the rent is $825, the average number of occupied units drops to 47. Assume that the relationship between the monthly rent p and the demand x is linear (Note:The term demand refers to thenumber of occupied units.)(a) Write a linear equation giving the demand x in terms of the rent p. (b) Linear extrapolation - Use a graphing utility to graph the demand equation and use the trace feature to predict thenumber of units occupied when the rent is raised to $855. (c) Linear interpolation - Predict the number of units occupied when the rent is lowered to $795.

Recent studies indicate that the average surface temperature of the earth has been rising steadily. Some scientists have modeled the temperature by the linear function T − 0.02t 1 8.50, where T is temperature in °C and t represents years since 1900. (a) What do the slope and T-intercept represent? (b) Use the equation to predict the average global surface temperature in 2100.

I had this class in college where the semester’s four exams weighed 10%, 15%, 25%, and 50%, respectively. The class average on each of the exams where 75%, 91%, 63%, 87%, respectively. Create two vectors in to represent the data. Calculate the dot product of your two vectors. What does the scalar value represent in terms of the class?

Suppose you're heading off for a long weekend (Friday, Saturday, and Sunday) somewhere and the weather report for your destination says: Chance of rain on Friday: 10% Chance of rain on Saturday: 25% Chance of rain on Sunday: 30% In each part below, find the chance exactly if it can be found using no further assumptions. If it can't be found, then (again using no further assumptions) find the best lower bound and upper bound that you can. a) the chance that it rains in your destination sometime during the long weekend
