The cost of belonging to a gym can be modeled by the function C(m)=50m+79.50, where C(m) is the total cost for m months of gym m
1 answer:
Answer:
Slope = 50 [monthly cost is $50 per month]
Y-Intercept = 79.50 [this is the initial cost of the membership, $79.50]
Step-by-step explanation:
The equation is:
This follows the general function y = mx + b
Where m is the slope and b is the y-intercept.
So, matching coefficients, we see that:
Slope = 50
Y-Intercept = 79.50
<em>THe meaning of slope is for every change in x-values, we have a change of m in y value. Thus, for every change in m (1 month), we will have change of 40 in y-value (which is the cost)</em>
<em>Thus, monthly cost is $50 per month.</em>
<em />
<em>Now, y intercept means the value of y(cost) at x = 0 (which is months = 0).</em>
<em>Thus, we can say when months = 0, initially, the cost is 79.50. So, this is teh initial cost of joining the gym.</em>

Since x is the number of seconds it took the rock to hit the water, x is the value that we are looking for. When the rock hits the water, it's height is 0, therefore, f(x) = 0. So, we can set the expression on the right equal to 0, and solve for 0. Let's do just that:
We can divide by -16, nothing will happen because 0 divided by anything is 0:
To factor any trinomial in standard form (given below), we must find two numbers that add to "b" and multiply to "c":
So, for this specific question, let's find two numbers that add to -8 and multiply to 9. These are clearly 9 and -1. We can write it in this way now:
Both answers would be valid, but there can't be negative time, so your answer is "It takes 9 seconds for the rock to reach the water."

Given an exponential function, say f(x), such that f(0) = 1 and f(1) = 2 and a quadratic finction, say g(x), such that g(0) = 0 and g(1) = 1.
The rate of change of a function f(x) over an interval
is given by
Thus, the rate of change (growth rate) of the exponential function, f(x) over the interval
is given by
Similarly, the rate of change (growth rate) of the quadratic function, g(x) over the interval
is given by
Therefore, the exponential grows at the same rate as the quadratic in the interval <span>.</span>
