The geometric sequence a_ia i a, start subscript, i, end subscript is defined by the formula: a_1 = -\dfrac13a 1 =− 3 1 a,

slava [35]

Answer:

1.014*10^35

Step-by-step explanation:

Given the following geometric sequence

$a_1 = \frac{-1}{3} \\a_i = a_{i-1}*(-3)$

Sum of nth term of the GP is expressed as;

$S_n = \frac{a(1-r^n)}{1-r}$

a = -1/3

n = 75

r = a2/a1

a2 = -3a1

a2 = -3(-1/3)

a2 = 1

r = 1/(-1/3)

r = -3

Substitute the given values in the formula;

$S_n = \frac{-1/3(3^{75} - 1)}{3-1}\\S_n = \frac{3^{75}-1}{-6} \\S_{75} = 1.014*10^{35}$

Hence the sum of the first 75 terms is 1.014*10^35

The area of trapezium shaped field is 480 square meter, the distance between two parallel sides is 15m and one of the parallel s

marissa [1.9K]

Answer: 44 m

Step-by-step explanation:

Given

The area of the trapezium is $A=480\ m^2$

Distance between parallel sides $h=15\ m$

One of the parallel sides is $20\ m$

Suppose the other parallel side is $x$

The area of the trapezium is

$A=\dfrac{1}{2}\times [\text{Sum of parallel sides}]\times h$

Put values

$\Rightarrow 480=\dfrac{1}{2}\times [20+x]\times 15\\\\\Rightarrow 480\times 2=300+15x\\\Rightarrow 960-300=15x\\\Rightarrow x=44\ m$
