To find the average of the data
Answer: x^12
Explanation: When the base (x) is the same and they are being multiplied the exponents are added. This is called/because of “The Product Rule for Exponents”.
Answer:
The. Answer. C
Step-by-step explanation:
Answer:
x^2-18x+y^2+18y+137=0
express both x and y term in completed square form
(x-9)^2 -81+(y+9)^2-81+137=0
(x-9)^2+(y+9)^2-25=0
(x-9)^2+(y+9)^2=5^2
here the x coordinate of the centre is +9
y coordinate is -9(the negative value of the value associated with the x and y square brackets)
radius=5
Answer:
B, C, D, and F
Step-by-step explanation:
The graph is an exponential curve rising upwards. By looking at the graph we can tell that the graph is only increasing, it touches the y-axis at 30 and it lies in the 1st quadrant.
So, option A is wrong, as the graph is increasing.
Option B is correct. The point where graph crosses/touches the y-axis is the y-intercept. So the y-intercept is 30.
Option C is correct. As the graph lies in 1st quadrant and is positive over the entire range of values.
Option D is also correct as the graph is increasing over entire range of values.
Option E is incorrect as y-intercept is 30.
Option F is correct. Since the graph is increasing, this means with every passing year the number of dolphins is increasing.
Therefore, the correct options are: B, C, D, and F
