Answer:

13 - 6n

Step-by-step explanation:

for the sequence 7, 1, -5, -11, -17

the sequence first term is 7

a= 7

Common difference (d) = T2 - T1 = T3 - T2

d = 1-7 = -5 -1

d = -6

Formula for nth term

Tn = a + (n-1)d

Tn = 7 + (n -1)-6

Tn = 7 -6n + 6

Tn = 13- 6n

= 13 - 6n

The sum of three consecutive even integers is 54. Find all three integers.

matrenka [14]

A good way to find the answer to these questions is to find it algebraically. Let's call the first number 'n'.
n + (n + 2) + (n + 4) = 54
3n + 6 = 54
3n = 48
n = 16
Therefore the numbers are 16, 18, 20

Answer:

hello your question is incomplete attached below is the complete question

answer :

for I1 = $\frac{1}{x^2} + \frac{4}{x^3}$ The integral converges

for I2 = $\frac{2x + 6}{2(x^2 + 6x + 4 )}$ The integral diverges

for I3 = $\frac{1}{x^2}$ The integral converges

for I4 = 1 The integral diverges

Step-by-step explanation:

The similar integrands and the prediction ( conclusion )

for I1 = $\frac{1}{x^2} + \frac{4}{x^3}$ The integral converges

for I2 = $\frac{2x + 6}{2(x^2 + 6x + 4 )}$ The integral diverges

for I3 = $\frac{1}{x^2}$ The integral converges

for I4 = 1 The integral diverges

attached below is a detailed solution

Plz help me Thx so much

Answer:

shipping and handling is <u>18.90</u> dollars

Step-by-step explanation:

percent means "per one hundred", so any percent can be written as a fraction over 100

30% = 30/100 = 0.30

Multiply 0.30 with the price 63 to get 0.30*63 = 18.90, which is the cost of shipping only. This result is added on top of the 63 dollars to get the total cost.
