You get this by adding all the marbles to find the total number of marbles. <em>10+7+12+9</em>, which equals <em>38</em>.
You have <u>10 red marbles out of 38 total</u>, so that is represented by !
Answer:
Step-by-step explanation:
A circumference of a circle can be determined by this: 2*pi*r
We're given the diameter. Divide that by 2 to get the radius.
6.45/2 = 3.225
Now multiply that by 2*pi. That gives us 2 * 3.14 * 3.225 = 20.253.
This could've also been done easier by doing pi*d where d is the diameter and you give the answer by multiplying them both. Also works, but the above formula is just key to many things and can also be used to derive the simpler one. Hope it helps! :)
Answer:
The graph has a domain of all real numbers.
The graph has a y-intercept at .
The graph has an x-intercept at .
Step-by-step explanation:
Given: The graph is
The domain of a function is a set of input values for which the function is real and defined.
Thus, the graph has a domain of .
To find the y-intercept: To find the y-intercept, substitute in
.
Thus, the y-intercept is
To find the x-intercept: To find the x-intercept, substitute in
.
Thus, the x-intercept is
