Future value = FV = $6000
Time period = n = 8
interest rate = r = 12%
Present value (PV) is calculated using the formula:
PV = FV/(1+r)n
Present Value = PV = 6000/(1+12%)8 = 6000/1.128 = 2423.299368
Answer -> 2,423
Answer:
If z =1/2, which expression has the greatest value?
1. (z^-2 z^5)^-2 = (z^3)^-2 = 1/z^6 = 1/(1/2)^6 = 2^6 = 64
2. (z^3)^5 = z^15 = (1/2)^15 = 1/(2^15)
3. z^-6 z^4 = z^-2 = (1/2)^-2 = 1/2^2 = 1/4
4.-(z^2 z^-4)^-3 is negative 64
1) x² + 8x + 15 = 0
Now what multiples to 15 and adds to 8? 5 and 3, 5x3=15, 5+3=8
so its
(x+5)(x+3)=0
now solve
x+5=0 x+3 =0
x = -5 x = -3
so the solution is -5, -3
4) x² - 11x + 28 = 0
what multiples to 28 and adds to -11? -7 and -4
(x-7)(x-4) =0
x= 7, 4
10) x² = 17x - 72 (okay ill do 3 of them)
first get numbers on same side where x² is positive
x² -17x + 72 = 0
what multiples to 72 and adds to -17? -9 and -8
(x-9)(x-8)=0
x= 9, 8
Answer:
Step-by-step explanation:
Use the cosine rule and see if the numbers hold true. a^2 = b^2 + c^2 - (2bc (cos x))
By substituting in our values I get that cos x = 0.838... which is possible. If cos x would equal 1.5, the there is no solution and the triangle would not be possible.
