Write an equation that represents each diagram and find the value of x.

[tex]\mathbb{ANSWER:}[/tex]

A.

The value of x by using the zero product property therefore option A is correct.

We have given that,

(x+3)(x+2)=0

we have to determine the technique that is most appropriate to use to solve each equation

The Zero Product Property simply states that if ab = 0, then either a = 0 or b = 0 (or both).

Therefore we have

(x+3)=0 and (x+2)=0

This implies that,

x+3=0

x=-3 and (x+2)=0 this implies that x=-2

Therefore we get the value of x by using the zero product property therefore option A is correct.

[tex]3\frac{3}{10}[/tex]

Step-by-step explanation:

Given: diameter = [tex]6\frac{3}{5}[/tex]

This is a mixed number.

We have to convert mixed numbers to improper fractions.

[tex]6*\frac{5}{5}+\frac{3}{5} \\ \frac{30}{5}+\frac{3}{5}=\frac{33}{5}[/tex]

diameter = 33/5

Now diameter = 2*radius so we divide 2 by diameter to get our radius.

[tex]\frac{33}{5} /2=\frac{33}{5}*\frac{1}{2} =\frac{33}{10}[/tex]

Improper fraction back to a mixed number.

10 can go into 33, 3 times so left with a 3 remainder.

[tex]\frac{33}{10}=3\frac{3}{10}[/tex]

Answer:

(x - 5)² + (y + 5)² = 9

Step-by-step explanation:

the equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k ) are the coordinates of the centre and r is the radius

here (h, k ) = (5, - 5 ) and r = 3 , then

(x - 5)² + (y - (- 5) )² = 3² , that is

(x - 5)² + (y + 5)² = 9

Answer: she was not correct, she messed up the equation.

Step-by-step explanation:

We will put this in y=mx +b form so first calculate the slope

m= (-4)-(-5)/(-4)-(-6)

m= 1/2. So y= x/2. +b

Now just substitute the x and y values of either given point to calculate b

I will use (-4,-4)

-4= (1/2)(-4) +b

-4= -2 +b

b=-2

So equation is y= x/2 -2

Answer:

Genetic drift

Step-by-step explanation:

I took da test

The term used to describe this phenomenon of future generation fluctuations would be Genetic drift.

Genetic drift refers to the random fluctuations in the number of offspring in a population.

Rabbits can exhibit several colors in their coats: black, white, tan, brown, red, and grey.

A disease randomly kills off most of the population and leaves only black and grey rabbits.

Future generations are only black or grey. We can see that the future rabbits have some common colors that are given by their parents.

So, this must be Genetic drift.

Answer:

[tex]a_{n}[/tex] = 1 + (n-1)84

Step-by-step explanation:

to solve a sequence there's a formula-

[tex]a_{1}[/tex]+(n-1)d

where a1 is the first term, and d is the common difference

since we know the first term, and we have a few subsequent terms we can solve for d and creat the general formula for the nth term

to find d we simply check the difference between two terms-

168-x = 84

168-84 = x

84 = x

we can confirm this by checking the next two even

252- x = 168

252 - 168 = x

84 = x

now we have enough for a general formula

[tex]a_{n}[/tex] = 1 + (n-1)84
