Given that <span>p represents "The shape is a rhombus", q represents "The diagonals are perpendicular", and r represents "The sides are congruent".

"if and only if" is represented using the biconditional logic operator (↔) and "and" is represented using the logical conjuction operator (∧).

Therefore, "The shape is a rhombus if and only if the diagonals are perpendicular and the sides are congruent” is represented by "p ↔ (q ∧ r)"

Answer:

1. you start with $ 3 and save $1 each month

2. your total savings is 3 times the number of month multiplied by itself

3. you save $3 the first month and then each month the amount triples

Step-by-step explanation:

1.

as y axis represents savings while x axis represents months

the statement "you start with $ 3 and save $1 each month"

is best described by the graph of straight line having slope of 1 and intercept of 3.

2. your total savings is 3 times the number of month multiplied by itself

          = 3(x)(x)

          = 3x^2

3.  as y axis represents savings while x axis represents months

the statement  "you save $3 the first month and then each month the amount triples" is best described by the exponential graph starting to rise from point (1,3) which means $3 save at 1 month.

You just plug 0 in for either x or y to get the other intercept since it’s in standard form
8x=35
X= 35/8
-7y=35
Y=-5
X-intercept: 35/8
Y intercept: -5

You are buying a mirror for your room. the store you go to has square mirrors with areas of 2.25 square feet and 6.25 square fee
zzz [600]

The side lengths of the mirrors are 1.5 ft and 2.5 ft respectively.

<u><em>Explanation</em></u>

Given that, the area of smaller mirror is 2.25 ft² and the area of larger mirror is 6.25 ft²

<u>Formula for the area of a square</u> :  A= a^2 , where a is the side of the square.

Lets assume, the side length of smaller mirror is x ft and the side length of larger mirror is y ft.

So....

x^2= 2.25\\ \\ x= \sqrt{2.25}=1.5

and

y^2= 6.25\\ \\ y= \sqrt{6.25}=2.5

Thus, the side length of smaller mirror is 1.5 ft and side length of larger mirror is 2.5 ft.
