Point (0, 0)

Point (1, -2)

Step 2: Find slope m

Substitute: $m=\frac{-2-0}{1-0}$
Subtract: $m=\frac{-2}{1}$
Divide: $m=-2$

marissa [1.9K]

Answer:

34.13 years

Step-by-step explanation:

Given formula:

G(t)= 63000(1 + 0.0255/4)^4t

Need to find the value of t when G(t) = 150000

150000 = 63000( 1+ 0.0255/4)^4t
( 1+ 0.0255/4)^4t = 150000/63000
( 1+ 0.0255/4)^4t = 2.3809
4t* log( 1+ 0.0255/4) = log 2.3809
4t *0.00275983965 = 0.37674115501
t = 0.37674115501/(4*0.00275983965)
t = 34.13 years rounded

What is the sum of the first 51 consecutive odd positive integers?

Angelina_Jolie [31]

We call:

$a_{n}$ as the set of the first 51 consecutive odd positive integers, so:

 $a_{n} = \{1, 3, 5, 7, 9...\}$

Where:
$a_{1} = 1$
$a_{2} = 3$
$a_{3} = 5$
$a_{4} = 7$
$a_{5} = 9$
and so on.

In mathematics, a sequence of numbers, such that the difference between two consecutive terms is constant, is called Arithmetic Progression, so:

3-1 = 2
5-3 = 2
7-5 = 2
9-7 = 2 and so on.

Then, the common difference is 2, thus:

 $a_{n} = \{ a_{1} , a_{1} + d, a_{1} + d + d,..., a_{1} + (n-2)d+d\}$

Then:

 $a_{n} = a_{1} + (n-1)d$

So, we need to find the sum of the members of the finite series, which is called arithmetic series:

There is a formula for arithmetic series, namely:

 $S_{k} = ( \frac{a_{1} + a_{k}}{2} ).k$

Therefore, we need to find:
 $a_{k} = a_{51}$

Given that $a_{1} = 1$ , then:

$a_{n} = a_{1} + (n-1)d = 1 + (n-1)(2) = 2n-1$

Thus:
$a_{k} = a_{51} = 2(51)-1 = 101$

Lastly:

$S_{51} = ( \frac{1 + 101}{2} ).51 = 2601$

help what is 3x+17=14

Brut [27]

To find the value of x we follow this:
3x+17=14
Take away 17 from both sides
3x=-3
Then divide by 3
x=-1
