Answer:
Step-by-step explanation:
1.51 gram to $ 1567.01 = 2.23 gram to $ x
1.51 / 1567.01 = 2.23 / x
cross multiply because this is a proportion
(1.51)(x) = (1567.01)(2.23)
1.51x = 3494.43
x = 3494.43 / 1.51
x = $ 2314.19 <===== what 2.23 grams of gold is worth
==========================
x = first car and y = new car
x = 28,033.51
y = 2x - 301.26
y = 2(28,033.51) - 301.26
y = 56,067.02 - 301.26
y = $ 55,765.76 <====== new car cost
Step-by-step explanation:
Use the Maclaurin expansion:
f(x) = ∑ₙ₌₀°° f⁽ⁿ⁾(0) xⁿ / n!
For example, for f(x) = eˣ:
f(x) = ∑ₙ₌₀°° e⁰ xⁿ / n!
f(x) = ∑ₙ₌₀°° xⁿ / n!
15,000 x .05 = 750
750 + 15,000 = 15,750
$15,750 is the total Robert paid for the used car.
Express 0.0346 as a function.
