Charlie is evaluating the product of 0.09 and 0.05. He multiplies, and before placing the decimal, arrives at an answer of 45. After considering the decimal placement, what is Charlie’s final answer? ♡ please hel!!!♡

the answer will be 00. 45

when the decimal point would move 4 place to the left

0.09×0.05= 0.0045

Step-by-step explanation:

when multiplying decimal numbers the final answer will have a number of decimal points equal to the sum of decimal points of the numbers that were multiplied. eg, 0.09 has 2 dp and 0.05 has 2dp. 2+2=4. The answer will have 4dp.

step-by-step explanation:

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.
