Yes this is an exponential function. One way we can determine this is to notice how each y term is multiplied by 6 to get the next y term
example: -2 times 6 = -12
another example: -12 times 6 = -72
The exponential function that models this data is y = -2*6^(x-1). Note how plugging in x = 1 leads to y = -2. Plugging in x = 2 leads to y = -12, and so on.
Answer:
D
Step-by-step explanation:
The first number in each co-ordinate is the same so -1 plus 4 is 5 units
The endpoints of a diameter of a circle are (4,-2) and (3,6). The area of the circle in terms of pi is 65pi
First, is to get the length of the diameter by getting the distance of the two points: (4, -2) and (3, 6)
dis = sqrt( (x2-x1)^2 + (y2-y1)^2)
dis = sqrt( (3-4)^2 + (6--2)^2 )
dis = sqrt( 1 + 64 )
dis = sqrt(65)
Next, is to find the area of the circle:
A = pi * r^2
A = pi * (sqrt(65))^2
A = 204.20 square units
The answer is b because you must simplify
