Answer:
The vertex is (-3, 7)
Step-by-step explanation:
As the equation is already in 'rectangular form), to work out the vertex, we can just compare this equation to that of the standard parabola y = x^2, and in particular, consider how it has been translated:
the (x+3) part moves the graph the the left 3 (i.e in the negative direction), while the +7 moves the graph up 7.
So as the vertex of the simple parabola y = x^2 is (0,0), the vertex of this graph is just (-3,7).
Note that the -2 at the front doesn't impact this vertex - this -2 just changes the 'scale' of the parabola (i.e makes it more narrow, and also turns it upside down as it's a negative number).
Answer:
The mean is 15
Step-by-step explanation:
To find the mean, add up all the numbers and divide by the number of numbers
(23+13+17+11+11)/ 5
75 /5
15
Answer:
The process is 'Squaring 1.4142135'
Step-by-step explanation:
We are given that,
1.4142135 is used repeatedly to approximate 2.
Now, we can see that ,
1.4142135 × 1.4142135 = 1.999999 ≅ 2
Thus, using the number 1.4142135 two times and taking their product approximates the number 2.
Hence, we used the process 'squaring the number 1.4142135' to obtain 2 approximately.
