A rectangular flowerbed at a city park has an area of 126 square meters.the width of the flowerbed is 3 meters.what is the perim

Alona [7]

First we need to find the length. So we do 126/3 to get 42. The length is 42. Now to find perimeter we do 2(42)+2(3) or 42+42+3+3.

Both ways are right ways. The perimeter is 90 meters.

Hope that helps!!

Question 18

ira [324]

Answer:

The function which represents this sequence will be:

$a_n=-15n+110$

Hence, option (A) is true.

Step-by-step explanation:

Given the sequence

$95, 80, 65, 50, ...$

An arithmetic sequence has a constant difference 'd' and is defined by

$a_n=a_1+\left(n-1\right)d$

computing the differences of all the adjacent terms

$80-95=-15,\:\quad \:65-80=-15,\:\quad \:50-65=-15$

As the difference is the same, so

$d = -15$

$a_1=95$

Thus, substituting $d = -15$ , $a_1=95$ in the nth term of an arithmetic sequence

$a_n=a_1+\left(n-1\right)d$

$a_n=-15\left(n-1\right)+95$

$a_n=-15n+110$

Therefore, the function which represents this sequence will be:

$a_n=-15n+110$

Hence, option (A) is true.

Answer:

4i√5

Step-by-step explanation:

$\sqrt{-80}=\sqrt{(-1)(16)(5)}=\sqrt{-1}\cdot\sqrt{16}\cdot\sqrt{5}=4i\sqrt{5}$
