Answer:
$855355.656503296, but we round to $855355.66
Step-by-step explanation:
Set up an equation where f(x)=650000(1.04)^n. The 1.04 represents the growth because if it were just .04 we wouldn't be including the initial value and it would decay. The 650000 is the initial value, and we put 1.04 to the nth power because it represents the amount of years. To plug in seven years, simply do 650000(1.04)^7 in your calculator.
Answer:
(x, y, z) = (2, 4, -5)
Step-by-step explanation:
You can use the last equation to write an expression for x that can be substituted into the first two equations.
... x = 11 +4y +5z
... 3(11 +4y +5z) -6y -3z = -3 . . . . substitute into the first equation
... 6y +12z = -36 . . . . . . . . . . . . . simplify, subtract 33
... y + 2z = -6 . . . . . . . . . . . . . . . . divide by 6 to put in standard form
___
... -3(11 +4y +5z) +2y -3z = 17 . . . . substitute into the second equation
... -10y -18z = 50 . . . . . . . . . . . . . simplify, add 33
... 5y +9z = -25 . . . . . . . . . . . . . . divide by -2 to put in standard form
Multiply the first of these equations by 5 and subtract the + 5(second.
... 5(y +2z) -(5y +9z) = 5(-6) -(-25)
... z = -5
You can use this in the first of the reduced equations:
... y + 2(-5) = -6
... y = 4 . . . . . . . . add 10
Then the expression for x will give that value:
... x = 11 +4(4) +5(-5)
... x = 2
The solution is (x, y, z) = (2, 4, -5).
Answer:
5/36
Step-by-step explanation:
Answer:
46.5 miles per hour
Step-by-step explanation:
Given that :
Speed of A car v in miles per hour based on length L in feets ;
V = √(20L)
Skid mark (L) = 108 feets
V = √(20 * 108)
V = √2160
V = 46.475800 miles per hour
V = 46.5 mph
