Trevor is making 2/3 of a recipe for chicken noodle soup. He adds ½ cup of chopped celery. The equation 2/3 c = 1/2 can be used
Nikitich [7]

Answer:

Cups of chopped celery in original recipe = \frac{3}{4}\ cups

Step-by-step explanation:

Given that:

Trevor is making 2/3 of a recipe

Number of cups of chopped celery used = 1/2 cup

The following equation can be used to find the original number of cups of chopped celery used in recipe.

\frac{2}{3}c=\frac{1}{2}

Multiplying both sides by 3/2

\frac{3}{2}*\frac{2}{3}c=\frac{1}{2}*\frac{3}{2}\\\\c= \frac{3}{4}\\

Hence,

Cups of chopped celery in original recipe = \frac{3}{4}\ cups

The estimated value of the integral from 0 to 2 of x cubed dx , using the trapezoidal rule with 4 trapezoids is
bulgar [2K]
The integral is approximated by the sum,

\displaystyle\int_0^2f(x)\,\mathrm dx\approx\sum_{n=0}^4\frac12\times\frac{f(x_n)+f(x_{n+1})}2=\frac14\sum_{n=0}^3(f(x_n)+f(x_{n+1}))

where f(x)=x^3 and x_n=\dfrac12n, giving you

\displaystyle\frac14\sum_{n=0}^3\bigg(\left(\frac n2\right)^3+\left(\frac{n+1}2\right)^3\bigg)
\displaystyle\frac1{32}\sum_{n=0}^3(n^3+(n+1)^3)
\displaystyle\frac1{32}\sum_{n=0}^3(2n^3+3n^2+3n+1)

Faulhaber's formulas make short work of computing the sum. You have

\displaystyle\sum_{n=0}^k1=k+1
\displaystyle\sum_{n=0}^kn=\frac{k(k+1)}2
\displaystyle\sum_{n=0}^kn^2=\frac{k(k+1)(2k+1)}6
\displaystyle\sum_{n=0}^kn^3=\frac{k^2(k+1)^2}4

which gives

\displaystyle\frac1{16}\sum_{n=0}^3n^3+\frac3{32}\sum_{n=0}^3n^2+\frac3{32}\sum_{n=0}^3n+\frac1{32}\sum_{n=0}^31
\displaystyle\frac{36}{16}+\frac{42}{32}+\frac{18}{32}+\frac4{32}
\implies\displaystyle\int_0^2x^3\,\mathrm dx\approx\frac{17}4=4.25

Zepler [3.9K]

Answer:

no

Step-by-step explanation:
