The formula below is used to calculate the area of a trapezium.
• a and b represent the length of the two parallel sides.
• h represents the height of the trapezium
Calculate the area of the trapezium at right using the formula below.

14 cm^2

Step-by-step explanation:

from the data given ,

A = 3 cm

B = 5 cm

H = 4

according to the given formula  ,

Area = H / 2 ( A + B )

Substituting values ,

Area = 4/2 * ( 3 + 4 )

Area = 4/2 * ( 7)

Area = 28 / 2

Area = 14

geometric series converge the common ratio r has magnitude less than one.

which is equivalent to

for the example we need

|2-x| < 1

-1 < 2-x   and 2-x < 1

x < 3 and x > 1

we can write that

answer: 1 < x < 3

1a. common ratio r=250/25=10 > 1     diverges

1b.   r=50/100=1/2 converges

when these converge they converge to

where a is the first term.

answer: 200

1c. r=-1   so it's not the case that |r| < 1.     diverges

2a. x is the common ratio so we converge when |x|< 1

2b.   r=-10x / -2 = 5x.

we converge when

|5x| < 1

|x| < 1/5

2c.   r=3-2x

-1 < 3-2x and 3-2x < 1

-4 < -2x and 2 < 2x

x < 2 and 1 < x

1 < x < 2

2d. [/tex] r=-48x^3/12 = 4x^3[/tex]

|4x^3| < 1

|x^3| < \frac 1 4

|x| < 4^{-1/3}

it will be a cylinder. with a diameter of 8 and 4 single pieces high
