If we approximate the function y=sin(x) with a0+a1 x a2 x^2 +a3 x^3, what is a0,a2,a2,a3?
Rashid [163]

The coefficients a_0,a_1,a_2,a_3 could be chosen to be the coefficients in the Maclaurin series of \sin(x).

We have

y = \sin(x) \approx a_0 + a_1 x + a_2 x^2 + a_3 x^3 \\\\ \implies y(0) = 0 = a_0

y' = \cos(x) \approx a_1 + 2a_2 x + 3a_3 x^2 \\\\ \implies y'(0) = 1 = a_1

y'' = -\sin(x) \approx 2a_2 + 6a_3 x \\\\ \implies y''(0) = 0 = 2a_2

y''' = -\cos(x) \approx 6a_3 \\\\ \implies y'''(0) = -1 = 6a_3

It follows that a_0=0, a_1=1, a_2=0, and a_3 = -\frac16.

Mia and Luke made 85 origami together. Mia made 4 pieces of origami every 3 minutes. Luke made 3 pieces of origami every 4 minut
julia-pushkina [17]
For ease of solving, let's first find the rate of Mia and Luke per minute. Since Mia can do 4 pieces every 3 minutes, then she can do \frac{4}{3} of a piece per minute. Luke on the other hand can do \frac{3}{4} of a piece per minute.

To find how many pieces they made, we first need to find the time it took for them to make the pieces. We assign t as the time Mia spent making origami. Since Luke spent 5 more minutes, we can denote his time as t+5.

Putting this into an equation we'll get:
\frac{4}{3}t+ \frac{3}{4}(t+5)=85
\frac{4}{3}t+ \frac{3}{4}t+\frac{15}{4}=85
\frac{25}{12}t=81.25
t=39

Therefore, Mia made pieces of origami for 39 minutes. Knowing this, we can find out the number of pieces of origami she made:
39* \frac{4}{3} =52

ANSWER: Mia made 52 pieces of origami.
