For the sequence given by a_n=2n+4 , answer the following:

artcher [175]

a. 6, 8, 10, 12, 14

Work:

a_1 = 2(1) + 4

a_1 = 6

a_2 = 2(2) + 4

a_2 = 8

a_3 = 2(3) + 4

a_3 = 10

a_4 = 2(4) + 4

a_4 = 12

a_5 = 2(5) + 4

a_5 = 14

b. 500

Work:

Since the common difference is 2, we can add 2 to each number until we reach the 20th term.

6 + 8 + 10 + 12 + 14 + 16 + 18 + 20 + 22 + 24 + 26 + 28 + 30 + 32 + 34 + 36 + 38 + 40 + 42 + 44 = 500

A trapezoid pyramid has a base area of 128 square centimeters. If it’s volume is 10,240 cubic centimeters, what is the height of

White raven [17]

Answer:

The height of the pyramid is $1.875\ cm$

Step-by-step explanation:

we know that

The volume of the trapezoid pyramid is equal to

$V=Bh$

where

B is the area of the trapezoid base

h is the height of the pyramid

we have

$B=128\ cm^{2}$

$V=240\ cm^{3}$

substitute and solve for h

$240=(128)h$

$h=240/(128)=1.875\ cm$

$Answer: \\ Since \: \widehat{SRT} = \widehat{STR} \: \\and \: \widehat{RTU} = \widehat{STR} + \widehat{STU} = 180^{\circ} \\ \Rightarrow \widehat{SRT} + \widehat{STU} = 180^{\circ} \\ \Leftrightarrow 4x - 20 + 6x = 180 \\ \Leftrightarrow10x = 200 \\ \Leftrightarrow x = 20 \\ \widehat{SRT} = 4 \times 20 - 20 = 60^{\circ}$
