Find the 25th of sequence 3,5,7,9,11
zubka84 [21]

Answer: The 25th term of the sequence is 75

Step-by-step explanation:

The given sequence depicts an arithmetic progression. The consecutive terms differ by a common difference. We will apply the formula for arithmetic progression.

Tn = a + (n-1)d

Tn = The value of the nth term of the arithmetic sequence.

a = first term of the sequence.

d = common difference (difference between a term and the consecutive term behind it)

n = number of terms in the sequence.

From the information given,

a = 3

d = 5-3 = 7-5 = 2

We want to look for the 25th term, T25

So n = 25

T25 = 3 + (25-1)2 = 3+ 24×2

T25 = 3 + 72 = 75

216 students enrolled in a freshman-level chemistry class. By the end of the semester, 5 times the number of students passed as
Semenov [28]

Answer:

The no. of student failed is 36.

Step-by-step explanation:

Given, the number of student enrolled= 216

Let us suppose number of student failed = x

Given,

no. of student passed is 5 times no. of student failed.

Then, no. of student passed = 5x

x +5x = 216

6x = 216

x = 216/6

x = 36

Thus, the no. of student failed is 36.

What is the answers to the question: Which rational expression is undefined when x = 0?
Rom4ik [11]

Answer:

option D

\frac{4x-8}{-2x^2}

Step-by-step explanation:

An expression is undefined when you get division by zero or in simple words when denominator is zero.

Now we will solve each expression one be one by plugging value of x = 0

<h3>1)</h3><h3>\frac{5x^2-4}{3x-3}</h3>

\frac{5(0)-4)}{3(0)-3}

-4/-3 = 4/3

<h3>2)</h3><h3>\frac{6x^2}{9x-3}</h3>

\frac{6(0)}{9(0)-3}

0/-3 = 0

<h3>3)</h3>

\frac{8x+6}{-x^2+1}

\frac{8(0)+6}{-0+1}

6/1

6

<h3>4)</h3>

\frac{4x-8}{-2x^2}

\frac{4(0)-8}{-2(0)}

<h3>-8/0</h3><h3>undefined</h3>
