Sarah and Joshua are trying to estimate the height of a parking garage using a 50 yards-long rope. Joshua is in the floor while Sarah stands on the top level of the garage. Each holds an end of the rope. Joshua walks away until the rope is completely tense, making a 30° angle with the floor and 60° with the garage wall. Joshua says the height can be calculated using the function sin (30) and determines the height is 25 yards. Sarah says the correct expression to be used is cos (60) and her calculation is that the height is 25 yards. Which one is correct?​

The graph shown below expresses a radical function that can be written in the form f(x)=a(x+k)1/n+c what does the graph tell you about the value of n in this function

Proceed as in example 3 in section 6.1 to rewrite the given expression using a single power series whose general term involves xk. ∞ n(n − 1)cnxn − 2 n = 2 − 4 ∞ ncnxn n = 1 + ∞ cnxn n = 0

An airplane consumes fuel at a constant rate while flying through clear skies, and it consumes fuel at a rate of 64 gallons per minute while flying through rain clouds. let c represent the number of minutes the plane can fly through clear skies and r represent the number of minutes the plane can fly through rain clouds without consuming all of its fuel. 56c+64r < 900056c+64r< 9000 according to the inequality, at what rate does the airplane consume fuel while flying through clear skies, and how much fuel does it have before takeoff? the airplane consumes fuel at a rate of gallons per minute while flying through clear skies, and it has gallons of fuel before takeoff. does the airplane have enough fuel to fly for 60 minutes through clear skies and 90 minutes through rain clouds?
