the given sets are,

D= {4,7,9} , let E {4,6,7,8}, and let F={3,5,6,7,9}

now,

D U E = { 4 , 6, 7 , 8, 9}

and'

E intersection F = E n F = {6 , 7)

thus, the answer is

D U E = { 4 , 6, 7 , 8, 9} and

E n F = {6 , 7)

True or false: Every sequence is either arithmetic or geometric. If this is true, explain. If false,

tiny-mole [99]

In an arithmetic sequence, the difference between consecutive terms is constant. In formulas, there exists a number $r$ such that

$a_{n+1}-a_n=r\quad \forall n\geq 1$

In an geometric sequence, the ratio between consecutive terms is constant. In formulas, there exists a number $r$ such that

$\dfrac{a_{n+1}}{a_n}=r\quad \forall n\geq 1$

So, there exists infinite sequences that are not arithmetic nor geometric. Simply choose a sequence where neither the difference nor the ratio between consecutive terms is constant.

For example, any sequence starting with

$1, 15, -3,\ldots$

Won't be arithmetic nor geometric. It's not arithmetic (no matter how you continue it, indefinitely), because the difference between the first two numbers is 14, and between the second and the third is -18, and thus it's not constant. It's not geometric either, because the ratio between the first two numbers is 15, and between the second and the third is -1/5, and thus it's not constant.

Ben made a model (shown below) of the square pyramid he plans to build when he grows up.

elena-s [515]

Answer:

$336 m^2$

Step-by-step explanation:

The surface area of a square pyramid is the sum of the area of the squared base + 4 times the area of each triangular face, therefore:

$A=A_b + 4A_t$

where:

$A_b=L^2$ is the area of the base, where

L is the length of the base

$A_t=\frac{1}{2}Lh$ is the area of each triangular face, where

h is the height of the face

Substituting,

$A=L^2+2Lh$

For the model in this problem,

L = 12

h = 8

Therefore, the surface area here is:

$A=12^2 +2(12)(8)=336$

There is no solution for the first one

if you eliminate y you get 2 equations
-13x - 13z = -25
-13x - 13x = -15

- there is no solution to theses

a23 means the element in the second row and the 3rd column

so its -5
