How many terms of the arithmetic progression 2,5,8..Must be taken to get a sum of 392?

AveGali [126]

Answer:

Number of term = 48

Step-by-step explanation:

GIven:

Arithmetic progression

2,5,8..

Total sum of Arithmetic progression is 392

Find:

Number of term

Computation:

First term a = 2

Difference d = 5 - 2 = 3

Sn = [n/2][2a + (n-1)d]

392 = [n/2][2(2) + (n-1)3]

392 = [n/2][4 + 3n - 3]

784 = [n][1 + 3n]

784 = n + 3n²

3n² + n - 784

n = 48 , n = -49

Number of term = 48

Point A is on a number line halfway between −17−17 and 55. Point B is halfway between point A and 0. What integer does the point

julia-pushkina [17]

Find A first by using formula: (a+b)/2= midpoint
so: A = [(-17)+(55)]/2
= 36

Now find B using midpoint formula:
B: (a+b)/2
=36+0/2
=18

1. Find the distance between two

BigorU [14]

Answer:

$\mathrm{D)\:}9.4\: \mathrm{units}$

Step-by-step explanation:

<u>Solution 1:</u>

Notice the $x$ coordinate of both points are equal, meaning both points are on a vertical line. The distance between two points on a vertical line is the absolute difference of their y-coordinates. The absolute difference between $4.7$ and $-4.7$ is $|4.7-4.7|=\fbox{$9.4$}$ .

<u>Solution 2:</u>

The distance between two points $(x_1,y_1)$ and $(x_2,y_2)$ is:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Plugging in given values, we have:

$d=\sqrt{(-2.6-(-2.6))^2+(4.7-(-4.7))^2},\\d=\fbox{$9.4$}$ .
