Step-by-step explanation:

The zeroes of the polynomial f(x) are 7, 6 and -1. The solution is obtained by the method of polynomial long division.

What is polynomial long division?

A long division polynomial is a formula for dividing one polynomial by another of the same degree or lower. The divisor, quotient, dividend, and remainder are all components of the long division of polynomials, just like they are for long division of numbers.

We are given f(7) = 0.

This means that (x-7) is one factor of f(x).

Using Polynomial Long Division,

Dividing :  x^3 -12x^2 + 29x + 42 ("Dividend")

By         :    x-7    ("Divisor")

Dividend     x^3  -  12x^2  +  29x  +  42

- divisor  * x2   x^3  -  7x^2        

Remainder      -  5x^2  +  29x  +  42

- divisor  * 5x     -  5x^2  +  35x    

Remainder             -       6x           +  42

- divisor  * (-6)            -       6x           +  42

Remainder                                  0

Quotient :  x^2-5x-6  

Remainder:  0

Now, factoring x^2-5x-6 , we get

⇒x^2-6x+x-6

⇒x(x-6)+1(x-6)

⇒(x+1)(x-6)

Thus, the factors are (x+1), (x-6) and (x-7).

Hence, the zeroes of the polynomial f(x) are 7, 6 and -1.

The coordinate of the intersection is (k, m*k + b).

A parallelogram is a four-sided shape with opposite sides that are parallel. The diagonal of a parallelogram cuts the shape into two congruent triangles. The coordinates of the intersection of the diagonal of a parallelogram with the vertical line of the parallelogram can be found by solving the equation of the line that forms the diagonal and the equation of the vertical line.

If the diagonal of the parallelogram is given by the equation y = mx + b, where m is the slope of the diagonal and b is the y-intercept, and the vertical line is given by the equation x = k, where k is the x-coordinate of the vertical line.

To find the x-coordinate of the intersection point, we can substitute x = k into the equation of the diagonal:

x = k

Then, we can substitute this value of x into the equation of the diagonal:

y = mx + b

This will give us the y-coordinate of the intersection point.

So, the coordinate of the intersection is (k, m*k + b)

Note: You need the equation of the diagonal and the equation of the vertical line to find the intersection point.

Therefore, The coordinate of the intersection is (k, m*k + b).

The number of bags of pink beads that can be made from today's shipment is given as follows:

5 bags.

The number of bags is obtained applying the proportions in the context of this problem.

We have that each bag weights 1/10 of a pound.

The shipment was of 4/7 pounds of pink beads, hence the total number of bags of pink beads that can be made from today's shipment is calculated as follows:

4/7/(1/10) = 4 x 10/7 = 40/7 = 5.

Y = [tex]4^{x}[/tex] + 64 = 5y - 1, x = (5y - 65)/16, and x = (20*[tex]4^{x}[/tex] - 260). Take the logarithm of both sides, apply the laws of logarithms, and solve for x.

A logarithm is a mathematical function for expressing the relationship between two integers. It is the exponent to which a base number must be increased in order to equal a particular number. The base-10 logarithm of 100, for example, is 2, because 10 to the power of 2 equals 100.

Let y = [tex]4^{x}[/tex]

[tex]16^{x}[/tex] + 64 = 5y - 1

[tex]16^{x}[/tex] = 5y - 65

Dividing both sides by 16

x = (5y - 65)/16

x = (5*[tex]4^{x}[/tex] - 65)/16

Substituting y = [tex]4^{x}[/tex]

x = (5*([tex]4^{x}[/tex]) - 65)/16

Simplifying,

x = (5*[tex]4^{x}[/tex] - 65)/16

x = (20*[tex]4^{x}[/tex] - 260)/16

Divide both sides by 20

x = ([tex]4^{x}[/tex] - 13)/2

Take the logarithm of both sides:

log(x) = log([tex]4^{x}[/tex] - 13)/2

Apply the laws of logarithms:

log(x) = x*log(4) - log(13)/2

Solve for x:

x = (log(13)/2)/log(4) - log(x)/log(4)

x = (log(13)/2 - log(x))/log(4)

The derivative of log₇(x) is 1/(xln(7))

To find the derivative of log₇(x), we can use the chain rule and the properties of logarithms.

The chain rule states that if we have a composite function, such as y = f(g(x)), then the derivative of y with respect to x is given by

dy/dx = dy/dg * dg/dx.

In this case, y = log_7(x) and g(x) = x, so

dy/dx = d/dx (log_7(x))

As by logarithmic property log₇x = ln(x)/ ln(7)

dy/dx = d/dx (ln(x)/ln(7))

To find the derivative of ln(x), we can use the property that the derivative of ln(x) is 1/x. This is because the natural logarithm function is the inverse of the exponential function eˣ, and the derivative of eˣ is eˣ. Therefore, the derivative of ln(x) is the reciprocal of x, or 1/x.

The differentiation of log₇(x) is given by:

d/dx (log₇(x)) = (1/x) * (d/dx (x)) * (1/ln(7))

= (1/x) * 1 * (1/ln(7))

= 1/(x ln(7))

Answer:

Nick is 6 years old.

Erica is 18 years old.

Step-by-step explanation:

Hello!

We know that Erica is 12 years older than Nick, which also means she is 3 times older than Nick. We can represent this situation as two equations.

Let E be Erica's age, and x be Nick's age.

E = x + 12, and E = x* 3

Since E is equal to E, we can say that x + 12 = 3x.

The value of x is 6. Nick is 6 years old, and Erica is 18 years old.

The measure of ∠V of the parallelogram is = 150.5°

A parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure

The four types are parallelograms, squares, rectangles, and rhombuses

Properties of Parallelogram

Opposite sides are parallel

Opposite sides are congruent

Opposite angles are congruent.

Same-Side interior angles (consecutive angles) are supplementary

Each diagonal of a parallelogram separates it into two congruent triangles

The diagonals of a parallelogram bisect each other

Given data ,

Let the measure of the angle ∠Y = 10x + 27

Let the measure of the angle ∠W = 2x + 29

Now , for a parallelogram the opposite sides are congruent and opposite angles are congruent

Substituting the values in the equation , we get

10x + 27 = 2x + 29

Subtracting 2x on both sides of the equation , we get

8x + 27 = 29

Subtracting 27 on both sides of the equation , we get

8x = 2

Divide by 8 on both sides of the equation , we get

x = 1/4

Let the measure of the angle ∠Y = 10 ( 1/4 ) + 27

Let the measure of the angle ∠Y = 2.5 + 27

Let the measure of the angle ∠Y = 29.5°

Now , same-side interior angles (consecutive angles) are supplementary

Substituting the values in the equation , we get

angle ∠Y + angle ∠V = 180°

29.5° + m∠V = 180°

Subtracting 29.5 on both sides of the equation , we get

m∠V = 150.5°

Hence , the measure of m∠V = 150.5°

We will solve our question with the help of the Multiplication rule.

As per the question, the baseball team has won 25 games and lost 12 games. This will give us a total of 25+12= 37 games.

It is given that if the baseball team rate continues through a 148-game season which is 37*4 = 148 games.

So, we should multiply our initial won matches by 4 to get the final won matches as per the given condition, we will get:

25*4 = 100 matches.

We can also find the answer by:

You would multiply 25 by 148 divided by 37 to determine the number of games won if you were comparing the 25 of the 37 games won to the total of 148 games played.

(148*25)/(25+12)
