Using prime factorization to rewrite 156 +36 as a product of the GCF and a sum of numbers will be 12(13 + 3).

Prime factorization simply means the process of writing all numbers based on the product of their prime.

In this case, it's important to note that:

156 = 13 × 12

36 = 3 × 12

Therefore, 156 + 36 will be:

= 12(13 + 3)

It will take approximately 54 years for the element to decay from 18 grams to 2 grams at a rate of 4% per year.

An exponential function is defined as a function whose value is a constant raised to the power of an argument is called an exponential function.

To determine how long it takes for an element to decay from 18 grams to 2 grams, you can use the formula:

t = (ln(A/B)) / (-r)

where:

t is the time it takes for the decay to occur

A is the initial amount of the element, in this case 18 grams

B is the final amount of the element, in this case 2 grams

r is the decay rate, in this case 4% per year

Plugging these values into the formula gives you:

t = (ln(18/2)) / (-0.04)

t = (ln(9)) / (-0.04)

t = (2.1972) / (-0.04)

t = -54.30

Hence, It will take approximately 54 years.

Answer:

  f(x) = 3(x +1)² +2

Step-by-step explanation:

You want the equation in vertex form of the parabola 3x² after its vertex is translated to (-1, 2).

The given form is the "vertex form" of the equation for a parabola. That is, in the form ...

  f(x) = a(x -h)² +k

the value of 'a' is the leading coefficient, the scale factor, and the values of h and k are the x- and y-coordinates of the vertex.

Given that the scale factor of the desired parabola is a=3, and the desired vertex is (h, k) = (-1, 2). we can fill in these values in the equation to get ...

  f(x) = 3(x -(-1))² +2

  f(x) = 3(x +1)² +2

Using the factorization of polynomial, the factor of the given expression is (3x-4)(x+2).

In the given question we have to find the each polynomial expression of 3x^2+2x-8.

The given expression is 3x^2+2x-8.

Now finding the factor of the given expression.

The multiply of the first and third variable is 24. The middle term is 2.

So the possible factor is 6 and 4.

3x^2+2x-8 = 3x^2+(6-4)x-8

3x^2+2x-8 = 3x^2+6x-4x-8

3x^2+2x-8 = 3x(x+2)-4(x+2)

3x^2+2x-8 = (3x-4)(x+2)

Hence, the factor of the given expression is (3x-4)(x+2).

As given in the question,

Recursive formula of the sequence is given by,

Aₙ = 2Aₙ₋₁  - 3Aₙ₋₂

And the value of

A₁ = -1 , A₂ = 1

Substitute the n = 3 , 4, 5, 6, 7, 8  in the recursive formula to get the value of A₈ we have,  

A₃ = 2A₂ - 3A₁

    = 2(1) -3(-1)

    = 5

A₄= 2A₃ - 3A₂

    = 2(5) - 3(1)

    = 7

A₅ = 2A₄ - 3A₃

    = 2(7) - 3(5)

    = -1

A₆ = 2A₅ - 3A₄

    = 2(-1) - 3(7)

    = -23

A₇ = 2A₆ - 3A₅

   = 2(-23) - 3(-1)

   = -43

A₈ = 2A₇ - 3A₆

The value at which acceleration is zero is t = 5/3

Acceleration is defined as the rate at which velocity changes with time, in terms of both speed and direction

Given: the equation of motion, velocity, s = t⁶ - 2t⁵

Since acceleration is the rate at which velocity changes with time.  You need to differentiate the velocity with respect to time. Thus:

ds/dt = 6t⁵ - 10t⁴                  (Note: ds/dt is the acceleration)

Also, acceleration is equal to zero. That is:

6t⁵ - 10t⁴ = 0

6t⁵ = 10t⁴

6t = 10

t = 10/6 = 5/3

Therefore, the value of t at which acceleration is zero is t = 5/3

Total number of boxes is 21:

This is your first equation.

The volume of a small box is a (since it is not given, if you have it please replace it with that number), and the volume of all small boxes is as.

The volume of a larger box is 14 cubic feet, and the volume of all large boxes is 14l cubic feet.

Total volume is 252 cubic feet, add the two volumes together:

And this is your second equation (don't forget to replace a with the volume of a small box).

The slope of a line that passes through the points (1,−2) and (2,2) is 4.

The two given points are (1,-2) and (2,2).

We know that the slope of a line passing through two points ([tex]x_{1} ,y_{1}[/tex]) and ([tex]x_{2} ,y_{2}[/tex]) is -

[tex]m = \frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

[tex]m = \frac{y_{2} -y_{1} }{x_{2} -x_{1} }\\= > m = \frac{2-(-2)}{2-1}\\ = > m = \frac{4}{1}\\ = > m = 4[/tex]

Woah, both of those are squares!!

Take the square root of both of those numbers

The probability that their babies would have brown wool will be 25%.

When two or more alleles for the same characters are present at the same loci on homologous chromosomes, a cell, a nucleus, or a single organism is said to be heterozygous. In contrast to homozygous, where the alleles are identical, it signifies that the alleles that code for the same gene or characteristic are different.

Given, the two-parent sheep would need to have heterozygosity for their genotype if we were to assume straightforward Mendelian genetics. Black would not be dominant in this situation; instead, the parents would be, shall we say, Rr for color. Imagine that each parent can only contribute one allele (either the R or the r). If both should chance to deliver the r, the child would be black.

Therefore, 25% of the following generation's children are likely to be black. There would be a 25% probability of a homozygous dominant offspring, a 50% chance of a heterozygous offspring, and a 25% chance of a homozygous recessive offspring if you filled out a Punnett square for this issue. Since white is the dominant allele in this situation, both the homozygous dominant allele, which accounts for 75% of the possibilities and the heterozygous child will be white. Since two recessive alleles are required to manifest the recessive phenotype, the remaining 25% of people are black.

An event's probability is a number between 0 and 1. In this case, 0 denotes the impossibility of the event and 1 represents certainty.

The probability of getting a head in a coin is 1/2.

Therefore, the probability of getting three heads on there flips will be:
