Solve the problem.When exposed to ethylene gas, green bananas will ripen at an accelerated rate. The number of days for ripening
Alex Ar [27]

The table and the plotted data are in the attachment.

Answer and Step-by-step explanation: A line of best fit is the best approximation of the given data. It is used to show the relation of two variables and it can be determined, more accurately, by the Least Square Method.

To use the method, follow the steps:

1) Calculate the mean of the two variables:

X = \frac{\Sigma x_{i}}{n}

Y=\frac{\Sigma y_{i}}{n}

2) The Slope of the line is given by:

m=\frac{\Sigma (x_{i}-X)(y_{i}-Y)}{\Sigma (x_{i}-X)^{2}}

3) The y-intercept is found by the formula:

b=Y-mX

For the ripening of bananas, the least square method gives the line:

y = -0.142x + 5.56

The rate of change of a line equation is its slope, so

Rate of change = -0.14

The rate of change of ripening time with respect to exposure time is -0.14, which means the more expose the fruit is, the less time it needs to ripe.

A basketball is thrown with an initial upward velocity of 30 feet per second from a height of 6 feet above the ground. The equat
Elena L [17]
For this case we have the following equation:
 h = -16t ^ (2) + 30t + 6
 We substitute the value of h = 10 in the equation:
 10 = -16t ^ (2) + 30t + 6
 Rewriting we have:
 0 = -16t ^ (2) + 30t + 6-10
 0 = - 16t ^ (2) + 30t - 4
 We look for the roots of the polynomial:
 t1 = 0.144463904
 t2 = 1.730536096
 "the ball passes its maximum height, it comes down and then goes into the hoop". Therefore, the correct root is:
 t = 1.730536096
 Answer:
 
It goes into the hoop after:
 t = 1.73 seconds
