False. Rhombuses can be a rectangle, but they not always are. Just like a rectangle can be a square, but they have to have the same amount for each side length

False. All rectangles can't be rhombuses because rectangles does not have to have all of the same sides, where on the other hand a rhombus does.

12 divided by 2 x the absolute value of 1.3 minus 2.16

yaroslaw [1]

The value of the expression (12/2)×| 1.3 - 2.16 | is 5.16 .

The Absolute Value of a number means writing the number without the negative sign .

For Example : the absolute value of -2 is |-2| = 2

In the question ,

an expression in words is given as "12 divided by 2 x the absolute value of 1.3 minus 2.16 "

the above expression in numbers can be represented by

= (12/2)×| 1.3 - 2.16 |

= 6 × | 1.3 - 2.16 |

= 6 × |-0.86|

= 6 × 0.86 .... because |-0.86| = 0.86

= 5.16

Therefore , The value of the expression (12/2)×| 1.3 - 2.16 | is 5.16 .

The given question is incomplete , the complete question is

Find the value of the expression " 12 divided by 2 x the absolute value of 1.3 minus 2.16 " ?

A sequence has an initial value (I) of -17 and its fourth term (a4) is 35. What is its general equation? Its 14th term?

aleksley [76]

Answer:

The sequence is an Arthemtic Progression

An=A1+(n-1)d

A1 is first term, An is nth term, n is number of term, and d is common difference

therefore

A4=35, A1= -17

A4=A1+(4-1)d

35= -17+3d

35+17=3d

52=3d

52/3=3d/3

14=d

common diffrence(d)=14

The general solution is given by

An= -17+(n-1)14

An= -17+14n-14

An= -31+14n

An= 14n-31

A14 term, means n=14

From An=A1+(n-1)d

A14= -17+(14-1)14

= -17+(13×14)

= -17+182

= 165.

Therfore, the 14th term is 165.

2. A sequence has a CR of 4/5 and its eighth term (a8) is (393216/3125). What is its general equation? Its 3rd term?

solution

common ratio(r)=4/5

eighth term(G8)=393216/3125

From Gn= G1r^(n-1)

G8 means n=8

G8=G1r^(n-1)

393216/3125=G1(4/5)^(8-1)

393216/3125=G1(4/5)^7

G1=(393216/3125)/(4/5)^7

G1=600

The first term is given by G1=600

Therefore

The General equation is given by

The General equation is given by Gn= 600(4/5)^(n-1)

3rd term (G3)

G3= G1(4/5)^(3-1) where n=3,

=600(4/5)^2

=600(16/25)

=384

Therefore, the 3rd term is given by G3= 384.
