let's firstly convert the mixed fractions to improper fractions.

\bf \stackrel{mixed}{2\frac{3}{5}}\implies \cfrac{2\cdot 5+3}{5}\implies \stackrel{improper}{\cfrac{13}{5}} \\\\[-0.35em] ~\dotfill\\\\ 4-\cfrac{13}{5}\implies \cfrac{4}{1}-\cfrac{13}{5}\implies \stackrel{\textit{LCD of 5}}{\cfrac{(5)4-(1)13}{5}}\implies \cfrac{20-13}{5}\implies \cfrac{7}{5}\implies 1\frac{2}{5}

express the limit as a definite integral on the given interval. lim n → [infinity] n ∑ i = 1 cos x i x i δ x , [ 2 π , 4 π ]
Lemur [1.5K]

The limit as a definite integral on the interval $\lim _{n \rightarrow \infty} \sum_{i=1}^n \frac{\cos x_i}{x_i} \Delta x$ on [2π , 4π] is $\int_{2\pi}^{4 \pi} \frac{\cos x}{x} d x$$.

<h3>What is meant by definite integral?</h3>

A definite integral uses infinitesimal slivers or stripes of the region to calculate the area beneath a function. Integrals can be used to represent a region's (signed) area, the cumulative value of a function changing over time, or the amount of a substance given its density.

Definite integral, a term used in mathematics. is the region in the xy plane defined by the graph of f, the x-axis, and the lines x = a and x = b, where the area above the x-axis adds to the total and the area below the x-axis subtracts from the total.

If an antiderivative F exists for the interval [a, b], the definite integral of the function is the difference of the values at points a and b. The definite integral of any function can also be expressed as the limit of a sum.

Let the equation be

$\int_a^b f(x) d x=\lim _{n \rightarrow \infty} \sum_{i=1}^n f\left(x_i\right) \Delta x$

substitute the values in the above equation, we get

= $\lim _{n \rightarrow \infty} \sum_{i=1}^n \frac{\cos x_i}{x_i} \Delta x$ on [2π, 4π],

simplifying the above equation

$\int_{2\pi}^{4 \pi} \frac{\cos x}{x} d x$$

Kate paid $118.65 for a jacket. the price includes a 5% sales tax. how much was the jacket before the tax?
Harman [31]

Let, the price of jacket before tax = x

it would be: x*105/100 = 118.65

x = 11865/105

x = $113

Solve the equation<br> 12 + 0.35x = 20.05
zubka84 [21]
X=23 First, you have to subtract 12 by 12 to cancel it out. Next, you have to do the same thing to 20.05. 20.05 minus 12 is 8.05. All you have left is .35x. To get rid of the this you have to divide .35x by .35. Now all you have left is x. Finally you have to do the same thing to 8.05. 8.05 divided by .35 is 23. So, x=23

Number 2 i need help
daser333 [38]
The table you drew under the question is exactly the right way to start.

-- Make a second column, next to the 6 and 7.  This column will be
the actual number of each thing.

-- You know that there are 42 marbles, so write '42' in the box
next to the 6, on the 'Marbles' line.
Now you need to figure out what to write in the 'Stones' line, next to the 7. 

--  Look at the 'Marbles' line.  There's a 6 and then a 42.
Ask yourself: "  Self !  What does the 6 have to be multiplied with to get 42 ?" 

-- Whatever the answer is, drop down to the 'Stones' line,
and multiply the 7 by the same number.
The product is the total number of stones, and it goes in the box.
.

(The mystery number is 7.  There are 49 stones.)
