F(x) should equal 3.36 because -1 time -.6^2 equals .36 and then you subtract 5 times -.6 from it so it'd be f(x)= 3.36. Sorry if I'm incorrect
Answer:
Step-by-step explanation:
12.82% increase
Step-by-step explanation:
((88-78)/78)*100 = 12.82%
Step 1. Find the difference between 78 and 88
Step 2. Divide that answer by the first number, 78
Step 3. Multiply that answer by 100 to get your percent
The total if all 236 coins were nickels would be $11.80, which is $3.95 short of the actual amount.
Replacing a nickel with a dime adds $0.05 to the total value, so there must have been $3.95/$0.05 = 79 such replacements.
There are 79 dimes.
There are 236 -79 = 157 nickels.
_____
Using the given variables, the problem statement gives rise to two equations. One is the based on the number of coins. The other is based on their value.
- n + d = 236
- .05n +.10d = 15.75
Solving the first for n, we get
... n = 236 - d
Substituting that into the second equation, we have
... .05(236 -d) +.10d = 15.75
... .05d = 15.75 -236·.05 . . . . . collect terms, subtract .05·236
... d = 3.95/.05 . . . . . . . . . . . . . divide by .05
... d = 79
... n = 236-79 = 157
___
The solution should look familiar, as it matches the verbal description at the beginning.
12*13*14*15*16 = 524160
Idk how to get this answer actually. It's just my first guess, and it happened to be right.
