Work must be shown for this problem! The figure shown below is a rectangle. Make sure to solve for x and BD. Give both answers b

Mila [183]

Answer:

x = 10

BD = 74

Step-by-step explanation:

Find x by setting 3x+7 equal to 37. Solve for x by subtracting 7 on both sides then divide by 3 to get x=10.

Since 37 is half of AC, multiply that by 2 to find AC or BD, which are the exact same length of 74.

Write a rule for the nth term of the sequence.

Helga [31]

Answer:

The rule for given sequence is: a_n = -27+16n

And the 100th term is: 1573

Step-by-step explanation:

Given sequence is:

-11, 5, 21, 37, 53, ...

Here

$a_1 = -11\\a_2 = 5\\a_3 = 21\\a_4 = 37$

First of all, we have to find if this is an arithmetic sequence

For that purpose, the common difference has to be found. Common difference, denoted by d, is the difference between consecutive terms of an arithmetic sequence

So,

$d = a_2 -a_1 = 5-(-11) = 5+11 = 16\\d = a_3 -a_2 = 21-5 = 16\\d = a_4-a_3 = 37-21 = 16$

As the common difference is same, the sequence is an arithmetic sequence

General rule for arithmetic sequence is:

$a_n = a_1+(n-1)d$

Putting values

$a_n = -11+(n-1)(16)\\a_n = -11+16n-16\\a_n = -27+16n$

For 100th term,

Putting n=100

$a_{100} = -27+16(100)\\a_{100} = -27+1600 = 1573$

Hence,

The rule for given sequence is: a_n = -27+16n

And the 100th term is: 1573
