Answer:
64
Step-by-step explanation:
total of a triangle adds up to 180 degrees
so:
76+37=116
180-116=64
C
Because .75 times 9 would give you the price of the books and then you would have to add C, the amount left to get to 20.
The answer is c because of Pythagorean’s theorem. a^2 + b^2 = c^2
So 5^2 + 12^2 = 13^2
25+144=169
First put the numbers in order to find the median:
26, 27, 28, 32, 32, 33, 35, 36, 38, 40, 42, 48
The number in the middle will be the median. In this case, there is an even number of data points so we will have to average the two numbers in the middle:
33 + 35 = 68...68/2 = 34. Therefore the median is 34
Now to get the inequality, add and subtract 6 from 34:
34 + 6 = 40
34 - 6 = 28
So the inequality is:
28 < x < 40
Answer:
The domain of the function is the set of all real numbers; the range of the function is the set of all nonnegative real numbers; the graph has an intercept at (0, 0); and the graph is symmetric with respect to the y-axis.
Step-by-step explanation:
This is not a square root function, this is a quadratic function, which has an x².
The domain, or set of x-values, is all real numbers. This is because all numbers work for x.
The range, or set of y-values, is the set of all nonnegative real numbers. This is because all numbers we get for y are positive real numbers.
The graph intersect both the x- and y-axis (x-intercept and y-intercept) at (0, 0).
The graph is decreasing on the interval x<0 and increasing on the interval x>0, not the other way around.
The graph has a minimum at (0, 0), not a maximum.
The graph can be folded in half along the y-axis, so it is symmetric with respect to the y-axis.
