Sladkaya [172]

So first we want to say, 8 out of the 40 flowers were perennials.

8 out of 40 is 8/40, or simplified down to 1/5.

1/5 in percentage form is 20% because 1 divided by 5 = 20%.

What are the first three terms of the sequence modeled by the recursive function an=1/2an-1 when a1=1?

loris [4]

Answer:

Option A is correct that is $1,\frac{1}{2},\frac{1}{4}$

Step-by-step explanation:

We have been given a formula $a_n=\frac{1}{2}\cdot a_n-1$

$a_1=1$

We will put values of n in $a_n=\frac{1}{2}\cdot a_n-1$

when n=2 we get

$a_2=\frac{1}{2}\cdot a_2-1$

$\Rightarrow a_2=\frac{1}{2}\cdot a_1$

$\Rightarrow a_2=\frac{1}{2}\cdot 1$

$\Rightarrow a_2=\frac{1}{2}$

when n=3

$a_3=\frac{1}{2}\cdot a_2$

$\Rightarrow a_3=\frac{1}{2}\cdot \frac{1}{2}$

$\Rightarrow a_3=\frac{1}{4}$

Therefore, Option A is correct that is $1,\frac{1}{2},\frac{1}{4}$

Please help me answer this equation

krok68 [10]

Answer:

Step-by-step explanation:

What you do is try to find l by using the given information.

We can start by saying that

A=L*W

Now it's easy algebra

Divide both sides by W

L=A/W

Area and length are given .

A=((m^3-3m+2)/2m^2-7m+3)/(m^3+m-2)/(2m^3+3m-2)

Try to work it out if you can't then tell me in the comments we'll figure it out.
