Answer:
The correct option is B.
Step-by-step explanation:
The amount of money, in dollars, in a savings account after x years is given by
This above equation represents that $10000 becomes M(x) after x years at a rate of interest 3% compounded in each year.
Therefore, the value in the expression 1.03 represents that there is a 3 percent increase in the savings account each year.
So, the correct option is B. (Answer)
Answer:
y-intercept is 30
Step-by-step explanation:
Given the model
comparing this model to the equation of a straight lines we can get the y- intercept
![y = 10x + 30\\\y= mx+c](https://tex.z-dn.net/?f=y%20%3D%2010x%20%2B%2030%5C%5C%5Cy%3D%20mx%2Bc)
The y- intercept is 30 which is the constant factor and it describes to us about the one-time registration fee of $30.
Answers:
f(-3) = -1
f(-1) = 2
f(3) = 5
======================================
Explanations:
Draw a vertical line through -3 on the x axis. Make sure this vertical line crosses the orange graph. Mark this point of intersection and then draw a horizontal line from this point to the y axis. You should find that it touches -1 on the y axis. Check out the attached image to see this process in action.
Those steps basically say that x = -3 leads to y = -1. Since y = f(x), this means f(-3) = -1
Through similar steps, you should find that f(-1) = 2 and f(3) = 5
Note that the open hole/circle does not count. So if you land on an open hole, just keep going until you hit a closed circle on the other piece of the graph.
Answer:
26.8
Step-by-step explanation:
x/145 = 18.5/100
cross-multiply:
100x = 2682.5
x = 26.8
