Answer:
.
Step-by-step explanation:
For function , the notation
means that when the input to the function is
, the output would be
.
The inverse function of a one-to-one function is commonly denoted as
.
The inverse function undoes the action of the original function. In this question, maps
to
. Thus,
would need to map
back to
. Therefore,
should be the corresponding input and output values.
Answer:
$142.95
Step-by-step explanation:
Given Original value of the sofa = $349
Rate of depreciation each year = 20%
Number of years = 4
To find the value of the sofa after 4 years use depreciation formula:
If the constant decrease in population be R% per annum. Then the population after n years is
= 142.9504
= 142.95 (Nearest cent)
Hence, the value of sofa after 4 years is $142.95.
Answer:
<h3>(A)</h3>The answers will have the same value, beacuse both scientific notations have the same coefficient, 4.2 and 1.4. Also, if you mentally subtract the exponents of those powers, you would have the same exponent. So, equal coefficient and equal exponent will give the same result.
<h3>(B)</h3>The value of each expression can be found by dividing coefficients and powers.
The value of each expression in standard form is
Remember that standard form refers to the number without the ten-power.
