An easy way to tell whether a graph is a function or not is to employ the verical line test. If you see any two y values that correspond to one x value, that means it is not a graph of a function, but rather a relation. In a we see that if we were to scan a vertical line from the left to right, there would be a point where an x value corresponds to two y values, which is at 2 to the left from the origin. In graph c you can find an x value that correspons to more than one y value at the origin, the same with graph b. With graph d, though, we see that all x values corresponds to only one y value so that graph is the one that is a function.
If you are trying to simplify 36(pi)/4, then 9(pi) would be what you want because it is the simplest form of that fraction. It also depends on the answer choices. Sometimes they want simplest form and other times they’ll have you leave the fraction as is. Typically simplifying completely is your best bet though.
Hope this helps!
Answer:
$27.50
Step-by-step explanation:
The amount of interest she will earn in a year is basically the initial amount multiplied by the rate of interest per year (in decimal).
We have to first convert 5 1/2% to decimal.
First,
1/2 means 0.5 (by dividing), so it becomes:
5.5%
Converting percentage to decimal is easy. We divide by 100, so we have:
5.5/100 = 0.055
Now we multiply:
500 * 0.055 = $27.5
So, in 1 year, Isabella earns an interest of $27.50
8 is the common factor
24÷8=3
48÷8=6
144÷8=18
round you volume measure to a whole number. like if it was 80.4 it would be 80
