Answer:

$a_{n}$ = 6n - 5

Step-by-step explanation:

There is a common difference d between the consecutive terms, that is

d =7 - 1 = 13 - 7 = 19 - 13 = 25 - 19 = 6

This indicates the sequence is arithmetic with n th term

$a_{n}$ = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 1 and d = 6, thus

$a_{n}$ = 1 + 6(n - 1) = 1 + 6n - 6 = 6n - 5

Answer:

Step-by-step explanation:

t1 = 1 = 6 * 1 - 5

t2 =7 = 6 * 2 - 5

t3 = 13 = 6 * 3 - 5

t4 = 19 = 6*4 - 5

t5 = 25 = 6*5 - 5

-------------------------

Tn = 6n - 5

Hope it helped :)

Why do you think a removable discontinuity (hole) doesn't produce an asymptote on the graph of a polynomial function, even thoug

Monica [59]

Because removable discontituity means that the limit of the function at that point has a finite value, and then you define the value of the function as that valu (the limit value).

An asymptote means that the limit of the function goes to positive or negative infinity.

You cannot meet both conditions, finite and infinity limit at the same time.

Answer:

1800

Step-by-step explanation:

Labor quantity variance= Actual quantity ×standard price - standard quantity ×standard price

Harper knows he is 50 yards from school. The map on his phone shows that the school is 34 inch from his current location. How fa

laila [671]

To solve this problem you must apply the proccedure shown below:

1. We know that 1 yard is 36 inches, therefore, 50 yards expressed in inches is:

$(50)(36)=1800in$

2. If he is 50 yards from school and the map shows that the school is 34 inches from his current location, when it shows 3 inches the real distance is:

$\frac{(1800in)(3in)}{34in}=158.82in$

3. If you can to express it in yards:

$\frac{158.82}{36} =4.41 yd$

Therefore, the answer is: 158.82 inches or 4.41 yards.
