Answer:
-7 / (x^2 +3x-10)
Step-by-step explanation:
1/ (x+5) - 1/(x-2)
we need to get a common denominator
1/ (x+5) * (x-2)/ (x-2) - 1/(x-2) * (x+5)/(x+5)
(x-2) / (x+5)(x-2) - (x+5)/ (x+5)(x-2)
Combine the numerator
(x-2 -x-5)/ (x+5)(x-2)
-7/(x+5)(x-2)
FOIL the denominator
-7 /( x^2 -2x +5x -10)
Combine terms in the denominator
-7 / (x^2 +3x-10)
Answer:
1st drop down menu is number of minutes, 2nd drop down menu is x-axis, 3rd drop down menu is temperature, and the 4th drop down menu is y-axis.
Answer:
40,320 different ways
Step-by-step explanation:
Here, we want to arrange 8 flags in a row
In the row, there will be 8 places
The first place has 8 flags to be chosen from
The second place has 7 and like that
So mathematically, the number of ways that we can arrange the flags is 8 factorial ways
We have this as:
8! = 40,320 different ways
Answer:
The better deal would be simple interest rate of 3.2%
Step-by-step explanation:
In order to calculate which bank would be the better deal If Parker decides to deposit $7,000 for 25 years, we would have to make the following calculation:
A. simple interest rate of 3.2%.
Therefore, FV= P*r*t
=$7,000*3.2%*25
=$5,600.
B. compound interest rate of 3%
Therefore, FV=PV(1+r)∧n
FV=$7,000(1+0.03)∧25
FV=$14,656
The better deal would be simple interest rate of 3.2%
