4x^5+16x^4+4x^3

Step-by-step explanation:

A=[2x^3-x+(8x^2+3x)]*4x^2/2=2x^2*(2x^3+8x^2+2x)

or A=4x^5+16x^4+4x^3

A prior study determined the point estimate of the population proportion as 58% ( = 0.58). The analysts decide to conduct a seco
Ksivusya [100]
The minimum sample size required for a test with a confidence interval of 100(1 - \alpha )% with a z-score of z_{ \alpha /2} and margin of error of E and a population proportion of p is given by:

n= \frac{p(1-p)z_{ \alpha /2}^2 \alpha }{E^2}

Given p = 58% = 0.58, E = 4% = 0.04, z_{ \alpha /2}=1.96

Therefore, 

n= \frac{0.58(1-0.58)(1.96)^2}{0.04^2} \\ \\ = \frac{0.58(0.42)(3.8416)}{0.0016} = \frac{0.93581376}{0.0016} \\ \\ =584.88=585

Find the 9th term of the following geometric sequence 1 -3 9 -27
gulaghasi [49]

Answer: The 9th term is 6561

Step-by-step explanation:

The geometric sequences have the following formula

a_n = a_1(r)^{n-1}

Where a_1 is the first term of the sequence and r is the common ratio between the consecutive terms of the sequence

In this case the sequence is   1 -3 9 -27

So a_1 = 1

Observe that the common ratio  r is:

r=\frac{-3}{1}=\frac{9}{3}=\frac{-27}{9}=-3

So the formula is:

a_n = (-3)^{n-1}

We want to find a_9

a_9 = (-3)^{9-1}

a_9 = (-3)^{8}=6561
