Answer:
90 arrangements
Step-by-step explanation:
Since there are no repititions of letters, there are unique 10 letters in total.
THe number of arrangements would be 2 permutation 10. We need the formula for permutation. That is:
Now, n = 10 [total] and r is 2, so we have:
So, there can be 90 arrangements
Answer:
A = $8406.6
Step-by-step explanation:
Given:
Average rate
Initial cost of painting
Time
We need to find the final amount of painting at the end of a 20-year.
Solution:
Using Exponential Growth rate formula as:
----------(1)
Where:
A = Final amount
a = Initial amount.
r = Rate as a decimal.
t = Time.
Now, we substitute all given values in equation 1.
Substitute in above equation.
A = $8406.62
Therefore, value of the painting at the end of a 20-year A = $8406.6
Hey there!☺
Equation
−(2x+5)+14=22 Simplify both sides
−2x + −5 + 14 = 22 Distribute
(−2x) + (−5+14) = 22 Combine Like Terms
-2x + 9 = 22
-2x + 9 - 9 = 22 - 9 Subtract 9 from both sides
-2x = 13
-2x/-2 = 13/-2
-13/2 Add the negative to 13
x = -13/2
Hope this helps!
