Given:

a) A color printer prints 17 pages in 6 minutes.

\begin{gathered} 17\text{ pages=6 minutes} \\ 1\text{ minute=}\frac{17}{6}\text{pages} \\ 1\text{minute =2.83 pages} \end{gathered}

A color printer prints 2.83 pages (approximately) per minute.

b) Cheng;s bike cost $40 rent for 8 hours.

\begin{gathered} \frac{x}{1}=\frac{8}{40} \\ x=0.2\text{ hours per dollar} \end{gathered}

How can you use similar triangles to find a missing measurement?
Vlad1618 [11]

Answer:

By comparison of the sides.

Step-by-step explanation:

If triangles are similar, that means their angles are equal and sides are proportional.

If you already have a proportion of two corresponding sides between triangles, then use that proportion and set it equal to a side you already know the measurement to. Hopefully that side is corresponding to your missing measurement, and you can then solve it.

Determine whether the following series converges or diverges using the integral test. Be sure to verify that the integral test c
Finger [1]

By using the integral test, series converges

What is an integral test for convergence and divergence?

⇒ It is used to prove the divergence or convergence of series. This test is called the integral test, which compares an infinite sum to an improper integral. It is important to note that this test can only be applied when we are considering a series whose terms are all positive.

How to know if a series is converging or diverging?

If the limit exists and is a finite number (a number less than infinity), we say the integral converges. If the limit is ±∞ or does not exist, we say the integral diverges.

let aₓ= f (x) is any function

⇒ In order for the integral test to work The function must be positive it has to be continuous and it has to be decreasing when x≥1

If the integral converges it means the series is also converging

If the integral diverges it means the series is also diverging

The sequence k^{3} /{e^{k^{4} } is clearly positive and decreases for k∈N then by the integral test,

\int\limits^\infty_1 {x^{3} /e^{x^4} dx \leq\displaystyle \sum^{\infty}_{k = 1} {x^{3} /e^{x^{4}

and

\int\limits^\infty_1 {x^{3} /e^{x^4} dx=1/4\int\limits^\infty_1 {x^{3} /e^{-u} du

⇒ 1/4 < \infty

So it comes with a finite value hence the series converges
