Pls help soon:)The graph below shows the total number of known cases of a virus over the weeks since the outbreak began.The curve of best fit to model the data is given below.y= 28, 141 (1.19)^xUse the exponential model to complete the following statements. Round to the nearest whole number, if necessary.There were initially ______ known cases of the virus.There were ______ known cases of the virus after six weeks.There were approximately 135,000 known cases after ______ weeks.
Accepted Solution
A:
Correct answers are: (1) 28, 141 known cases (2) 79913.71 known cases after six weeks (round off according to the options given) (3) After approx. 9 weeks (9.0142 in decimal)
Explanations: (1) Put x = 0 in given equation y= 28, 141 (1.19)^x y= 28, 141 (1.19)^(0) y= 28, 141
(2) Put x = 6 in the given equation: y= 28, 141 (1.19)^x y= 28, 141 (1.19)^(6) y= 79913.71
