The population of a local species of beetle can be found using an infinite geometric series where a1 = 880 and the common ratio

nasty-shy [4]

<span>Data:

infinite geometric series

Make a the subject of the formula x²=a²-a²w²

Gwar [14]

Answer:

a = ± $\sqrt{\frac{x^2}{1-w} }$

Step-by-step explanation:

Given

x² = a² - a²w ← factor out a² from each term on the right side

x² = a²(1 - w) ← divide both sides by (1 - w)

$\frac{x^2}{1-w}$ = a² ( take the square root of both sides )

± $\sqrt{\frac{x^2}{1-w} }$ = a

Which of the following is not a solution to the equation −2x + 3y = 9.

lakkis [162]

Given that the equation $-2x+3y=9$

We need to determine the coordinate that is not a solution to the equation.

<u>Option A</u>: (0,3)

Substituting the coordinate (0,3) in the equation $-2x+3y=9$ , we get;

$-2(0)+3(3)=9$

$0+9=9$

$9=9$

Since, both sides of the equation are equal, then the coordinate (0,3) is a solution to the equation.

Hence, Option A is not the correct answer.

<u>Option B</u>: (1,-3)

Substituting the coordinate (1,-3) in the equation $-2x+3y=9$ , we get;

$-2(1)+3(-3)=9$

$-2-9=9$

$-11\neq 9$

Since, both sides of the equation are not equal, then the coordinate (1,-3) is not a solution to the equation.

Hence, Option B is the correct answer.

<u>Option C</u>: (-3,1)

Substituting the coordinate (-3,1) in the equation $-2x+3y=9$ , we get;

$-2(-3)+3(1)=9$

$6+3=9$

$9=9$

Since, both sides of the equation are equal, then the coordinate (-3,1) is a solution to the equation.

Hence, Option C is the correct answer.

Therefore, the coordinate (1,-3) is not a solution to the equation $-2x+3y=9$
