What exponential function is the best fit for the data in the table? x f(x) 1 −4 3 −1 4 3f(x) = 4(3)x − 1 + 4f(x) = 4(3)x − 1 −4f(x) = one fourth (3)x − 1 + 4f(x) = one fourth (3)x− 1 −4

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

the answer is 62.8 cubic units
