How can you use what you know about square numbers to find the square root of a non-perfect square number

Harrizon [31]

Finding the square<span> root of a </span>number<span> is the inverse operation of squaring that </span>number<span>. Remember, the </span>square<span> of a </span>number<span> is that </span>number<span> times itself. The perfect squares are the squares of the whole </span>numbers<span>. The </span>square<span> root of a </span>number<span>, n, written below is the </span>number<span> that gives n when multiplied by itself.

A type of organism's cells split every minute. If the organism has 4 cells when the cells begin to split, how many cells will th

snow_lady [41]

Answer:

The total of cells will the organism have after 6 minutes is 252

Step-by-step explanation:

* Lets consider this problem as a geometric series

- There is a constant ratio between each two consecutive numbers

Ex:

# 5 , 10 , 20 , 40 , 80 , ………………………. (×2)

# 5000 , 1000 , 200 , 40 , …………………………(÷5)

* General term (nth term) of a Geometric series:

∵ U1 = a , U2 = ar , U3 = ar^2 , U4 = ar^3 , U5 = ar^4

∴ Un = ar^n-1

- Where r is the ratio between each two consecutive terms and

n is the position of the number in the series

* The sum of first n terms of a Geometric Progression is calculate from

Sn = a(1 - r^n)/1 - r

- In the problem the cell split every minute

- The organism has 4 cells when the cells begin to split

∴ a = 4

# 4 , 8 , 16 , 32 , .......

∴ r = 2

- The total of cells will the organism have after 6 minutes can

calculate from the rule of the sum

∴ S6 = 4(1 - 2^6)/1 - 2 = 4(1 - 64)/-1 = 4(-63)/-1 = 252 cells

Answer:

-(5x-21)/6 so d

Step-by-step explanation:

to do inverse functions you want to replace the x in the function with y so x=(21-6y)/5, then solve for y and you will get the answer I got and its d

UNO [17]

Answer:

See explanation

Step-by-step explanation:

Consider given statement "If a figure is a cube, then it has eight vertices" in math terms. Let

statement p be "A figure is cube.";
statement q be "A figure has 8 vertices."

Then the statement "If a figure is a cube, then it has eight vertices" can be written as

$p\Rightarrow q$

Converse ( $q\Rightarrow p$ ): If a figure has eight vertices, then it is a cube.

Inverse ( $\neg p\Rightarrow \neg q$ ): If a figure is not a cube, then it has not eight vertices.

Contrapositive ( $\neg q\Rightarrow \neg p$ ): If a figure has not eight vertices, then it is not a cube.
