The sum of the first three terms of A.P is 18 if the first term is 4 find their product​
Nataly_w [17]

Answer:

192

Step-by-step explanation:

The sum of the first 3 terms of the A. P is

a + a + d + a + 2d = 18, that is

3a + 3d = 18 ← substitute a = 4

12 + 3d = 18 ( subtract 12 from both sides )

3d = 6 ( divide both sides by 3 )

d = 2

Thus the first 3 terms are

4, 6, 8 and their product = 4 × 6 × 8 = 192

a rectangular prism is 11 3/5 meters long ,9 meters wide ,and 12 1/2 meters high. what is the volume,in cubic meters,of the pris
Katen [24]
The volume of this prism is 
V=l*w*h
rewrite the mixed number as fractions
V= 11 3/5* 9* 12 1/2=
V= 58/5 *9/1* 24/2
V=58*9*24/5*2
V=12528/10=1252 8/10 m^3
or
V=1252.80m^3

The proportionality constant of the given graph is k = 16.

<h3>How to find the proportionality constant of a graph?</h3>

The proportionality constant of a graph is the ratio of the y-coordinates to the x-coordinates.

Thus, it is written as k = y1/x1 = x2/y2 = ... = yn/xn

<h3>Calculation:</h3>

The given graph has the coordinates as

x = 0; y = 0 i.e., (0, 0)

x = 0.5; y = 8 i.e., (0.5, 8)

x = 1; y = 16 i.e., (1, 16)

x = 1.5; y = 24 i.e., (1.5, 24)

and so on.

Then, the ratio of y - coordinate to the x - coordinate is

k = 8/0.5 = 16

or

k = 16/1 = 16

or

k = 24/1.5 = 16

and so on.

So, the proportionality constant for the given graph is k = 16.
