Answer:

w = -15

Step-by-step explanation:

-5w = 7 - 4w + 8

Grouping like terms together,

-5w+4w = 7+8

-w = 15

w = -15

Veronika [31]

The expression of integral as a limit of Riemann sums of given integral \int\limits^5_b {1} \, x/(2+x^{3}) dxis 4 \lim_{n \to \infty}∑n(n+4i)/2n^{3}+(n+4i)^{3} from i=1 to i=n.

Given an integral \int\limits^5_b {1} \, x/(2+x^{3}) dx.

We are required to express the integral as a limit of Riemann sums.

An integral basically assigns numbers to functions in a way that describes displacement, area, volume, and other concepts that arise by combining infinite data.

A Riemann sum is basically a certain kind of approximation of an integral by a finite sum.

Using Riemann sums, we have :

\int\limits^b_a {f(x)} \, dx=\lim_{n \to \infty}∑f(a+iΔx)Δx ,here Δx=(b-a)/n

\int\limits^5_1 {x/(2+x^{3}) } \, dx=f(x)=x/2+x^{3}

⇒Δx=(5-1)/n=4/n

f(a+iΔx)=f(1+4i/n)

f(1+4i/n)=[n^{2}(n+4i)]/2n^{3}+(n+4i)^{3}

\lim_{n \to \infty}∑f(a+iΔx)Δx=

\lim_{n \to \infty}∑n^{2}(n+4i)/2n^{3}+(n+4i)^{3}4/n

=4\lim_{n \to \infty}∑n(n+4i)/2n^{3}+(n+4i)^{3}

Hence the expression of integral as a limit of Riemann sums of given integral \int\limits^5_b {1} \, x/(2+x^{3}) dxis 4 \lim_{n \to \infty}∑n(n+4i)/2n^{3}+(n+4i)^{3} from i=1 to i=n.

The answer is x-4. There is no way to find out the value of x because it is not an equation.

exis [7]

Answer:

24

Step-by-step explanation:

Let Noah = x.  I will write the equation in order of appearance with Noah first.

x + 3x + (3x + 5) + (3x + 12) + (x - 4) + 2(x-4) = 317

Distribute where needed and remove parentheses

x + 3x + 3x + 5 + 3x + 12 + x - 4 + 2x - 8 = 317

Collect like terms

13x + 5 = 317

Move the constant to the right of the equal sign and do the math

13x = 312

Divide both sides by 13
