Answer:

Option A is the correct choice.

Step-by-step explanation:

Please find the attachment.

We have been given an equation y=2x-4 and we are asked to find the graph that represents our given equation.

We can see that our given equation is slope-intercept form of equation y=mx+b, where,

m = Slope of line,

b = The y-intercept or initial value.

So, the graph for our given equation will have a slope of 2 and it will y-axis at y=-4.

Upon looking at our given options we can see that graph represented by option A has a slope of 2.

Slope=\frac{y_2-y_1}{x_2-x_1}

Upon substituting coordinates of points (2,0) and (3,3) in slope formula we will get,

Slope=\frac{2-0}{3-2}

Slope=\frac{2}{1}

Slope=2

Therefore, the graph represented by option A is the correct choice.

Express the limit as a definite integral on the given interval. lim n→[infinity] n xi ln(1 + xi2) Δx, [2, 7] i = 1
xenn [34]

Answer:

Step-by-step explanation:

Consider \  the \ following \ series

\lim_{n \to \infty}  \sum \limits ^n_{i=1} x_i \ In ( 1+ x_i^2) \Delta x , [2,7]

Let's \ recall \ the \ explanation \  of definite \ integral \ in  \ terms  \ of  \ Riemann \ sum

\int^b_a \ f(x) \ dx =  \lim_{n \to \infty}  \sum \limits ^n_{i=1} \ f(x_i) \Delta x , \ where \ \Delta x = \dfrac{b-a}{n}

By  \ efinition,  \ the \  limit \   is \  then \  expressed \   as  \  integral

\lim_{n \to \infty} \sum ^a_{i=1} \ x_i \ In (1+x_i^2) \Delta x = \int^7_2 xIn (1+x^2) \ dx

The amount of water decreases 16\frac{1}{2} pints in 12 weeks.

Solution:

The amount of water decreases in 7 weeks = 9\frac{5}{8} pints

The amount of water decreases each week is same.

Let us first change the mixed fraction into improper fraction.

9\frac{5}{8} pints = \frac{(9\times8)+5}{8}

             =\frac{77}{8} pints

The amount of water decreases in 1 week

              $=\frac{\frac{77}{8} }{7}

              =\frac{77}{8\times7}

              =\frac{11}{8}

So, the amount of water decreases in 1 week is \frac{11}{8} pints.

The amount of water decreases in 12 week

               =\frac{11}{8}\times12

               =\frac{132}{8}

               =16\frac{4}{8}

               =16\frac{1}{2} pints

Hence the amount of water decreases 16\frac{1}{2} pints in 12 weeks.
