(3x10,000) + (12x1,000) +(4x100) + (8x10)+(7x1)

The answer is 42487 and it was very complicated

You would do 3 x 10 but then add three zeros then if you x twelve by 10 you get 120 but the. You need to add 2 zeroes on 4 x 100 is four hundred eight times 10is eighty 7x1 is 7 then add
30,000
12,000
400
80
7
The work that out and there's your answer

Answer

1 number

explanation

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

 

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.

The correct answer is -4
