Write an expression so that the product of a whole number and a decimal is.0.28

Let

x-------> the whole number

y------> the decimal number

we know that

------> equation 1

assume the value of x and then calculate the value of y

Let

x=280

solve for y in the equation 1

substitute the value of x

therefore

the expression is equal to

280*0.001=0.28

1 number

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 answer is 5/14.

hope this .
