Answer:
y = -cos(x) -2
Step-by-step explanation:
Multiplying the function value by -1 reflects it across the x-axis. Adding -2 to the function value shifts it down by two units.
reflected: y = -cos(x)
then shifted: y = -cos(x) -2
Answer:
the first one
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
here (h, k) = (10, - 6) and r = 6, hence
(x - 10)² + (y - (- 6))² = 6², that is
(x - 10)² + (y + 6)² = 36

11.6 is the correct answer.
Answer:
Mean: 49
Step-by-step explanation:
The mean is the sum of all of the numbers divided by the total number of numbers. So, there are 7 numbers you gave.
The sum of 45+50+47+52+53+45+51 = 343.
Divide 343 by 7 and you get 49.
Answer:
Median: 50
Step-by-step explanation:
The median is the middle number when you sort out the entire list. First, you have to sort out the entire list:
45, 45, 47, 50, 51, 52, 53
Then, pick out the middle number. The middle number will always have the same number of numbers on either side. 50 is in the middle, and there are three numbers on either side of the 50.
