Answer:
25
Step-by-step explanation:
We require to solve for n, hence
n(n + 1) = 325
multiply both sides by 2 to eliminate the fraction
n(n + 1) = 650
n² + n = 650
subtract 650 from both sides to have equation in standard form
n² + n - 650 = 0 ← in standard form
(n + 26)(n - 25) = 0 ← in factored form
equate each factor to zero and solve for n
n + 26 = 0 ⇒ n = - 26
n - 25 = 0 ⇒ n = 25
however, n > 0 ⇒ n = 25
Answer:21
Step-by-step explanation: solve whats in the numerator then solve whats in the denominator then you divide
Answer:
f(n) = 1
Step-by-step explanation:
Another answer for -3. FxN= -3
Given that <span>Jim uses the function f(x) = 0.7x + 23 to determine the amount he charges for each used drone he sells, where x is the original value of the drone and that t</span><span>he function g(x) = 1.08x is used to determine the amount a customer pays for a drone at Jim’s store including 8% sales tax.
</span> The <span>function to determine the total amount a customer pays for a used drone at Jim’s store including 8% sales tax is given by
f(x) + g(x) = 0.7 + 23 + 1.08x = 1.78x + 23.
