Step-by-step explanation:

I choose to work 3 problems to show how multiplication and division work with exponents.

12. You are looking for the coefficient of the x² term. It will be the sum of the coefficients of partial products that result in the variable being x². Those partial products will be of the form (ax²)(b) or (ax)(bx).

We note there are both x² and x terms in the first factor, but only x terms in the second factor. So, the x² term of the product will be ...

  (2x²)(4) +(5x)(x) = (8 +5)x² = 13x²

The missing coefficient is 13.

14. The rules of exponents are ...

  (a^b)(a^c) = a^(b+c)

  (a^b)^c = a^(bc)

  (a^b)/(a^c) = a^(b-c)

The given expressions can be simplified as ...

15. The given expression is of the form

  [tex]\dfrac{\text{dividend}}{\text{divisor}}=\dfrac{14x^2+10x-7}{2x}\\\\=\dfrac{14x^2}{2x}+\dfrac{10x}{2x}-\dfrac{7}{2x}=(7x+5)+(-\dfrac{7}{2x})=\text{(quotient)+(remainder)}[/tex]

The true statement is ...

  the quotient has a remainder of -7/(2x)

__

Additional comment

Strictly speaking, a division problem can be expressed as ...

  dividend = (divisor)(quotient) + remainder

In this instance, this would be ...

  14x² +10x -7 = (2x)(7x +5) -7

which is to say that -7 is the remainder. The term -7/(2x) is actually part of the quotient.

The above (quotient) + (remainder) should actually be ...

  (quotient) +(remainder)/(divisor)

You will notice the answer choices have the terms "dividend" and "divisor" swapped, and that the degree of the binomial quotient is 1, not 2. Thus the only choice that begins to make sense is the one highlighted above--even though it, too, is technically incorrect.

Step-by-step explanation:

Answer:

l = t/4v² - 1

Step-by-step explanation:

Given the expression

v = √l+t/2√l

We are to make l the subject of the formula as shown;

Cross multiply

2v√l =  √l+t

Square both sides

(2v√l)² =  (√l+t)²

4v²l = l+t

t = 4v²l - l

t = l(4v² - 1)

Divide both sides by 4v² - 1

t/4v² - 1 = l(4v² - 1)/4v² - 1

t/4v² - 1 = l

Swap

l = t/4v² - 1

Hence the required expression for l is t/4v² - 1

Decimal numbers are number that contains decimal points. The value  123.7561 rounded to nearest hundredth is 123.76

Decimal numbers are number that contains decimal points in between the values.

Given the decimal value 123.7561, we are to convert the decimal values to the hundredth place.

This means that there must only be two values after the decimal points and the values rounded up if greater than 4.

Hence the value  123.7561 rounded to nearest hundredth is 123.76

Answer:

0.37

Step-by-step explanation:

To resolve the given problem we will apply

persistent time Markov chain :   n = 0, 1, . . . , 4

 n = number of individuals pausing

where The equalization conditions are : πn = ( πn - 1/2 )

Given that  :

n = 0,1,2,3,4

π0 = 1/( 1 + 2−1 + 2−2 + 2−3 + 2−4) = 0.52 = 16/31

Also the normal number of travelers found by Ella will be represented as

E(N) = (π1 + 2π2 + 3π3) / ( π0 + π1 + π2 + π3) ------- ( 1 )

where : π1 = 8,  π2 = 4,  π3 = 2 , π0 = 16/31  input values into equation 1

E ( N ) =  22/30

given that the True to form hanging tight time = 0.5

hence Holding holding time = E(N ) * 0.5

therefore  the expected waiting time for Ella = ( 22/30 ) * 0.5 = 0.37

Answer:

The answer to your question is the third one

Step-by-step explanation:

The first graph is the graph of a

The second graph is of a rational function

The third one is of an exponential function

vasta third one dzuh

Any graph that looks like the above (big on the left and crawling along the x-axis on the right) displays exponential decay, rather than exponential growth. For a graph to display exponential decay, either the exponent is "negative" or else the base is between 0 and 1.

Given:

The line through (6, −3) and (7, 6) is perpendicular to the line through (−2, 5) and (x, −1).

To find:

The value of x.

Solution:

Slope formula: If a line passes through two points, then the slope of the line is:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

The slope of the line through (6, −3) and (7, 6) is:

[tex]m_1=\dfrac{6-(-3)}{7-6}[/tex]

[tex]m_1=\dfrac{6+3}{1}[/tex]

[tex]m_1=9[/tex]

The slope of the line through (−2, 5) and (x, −1) is:

[tex]m_2=\dfrac{-1-5}{x-(-2)}[/tex]

[tex]m_2=\dfrac{-6}{x+2}[/tex]

We know that the product of slopes of two perpendicular lines is -1.

[tex]m_1\cdot m_2=-1[/tex]

[tex]9\cdot \dfrac{-6}{x+2}=-1[/tex]

[tex]\dfrac{-54}{x+2}=-1[/tex]

Multiplying both sides by (x+2), we get

[tex]-54=-1(x+2)[/tex]

[tex]-54=-x-2[/tex]

[tex]-54+2=-x[/tex]

[tex]-52=-x[/tex]

Divide both sides by -1.

[tex]52=x[/tex]

Therefore, the value of x is 52.

Answer:

3. 30 degrees

4. 46 degrees

5. 55 degrees

Step-by-step explanation:

3. Let it be x

85+65+X=180

150 + x = 180

x = 180 - 150

x = 30 degrees

4. Let it be x

104 + 30 + x = 180

134 + x = 180

x = 180 - 134

x = 46 degrees

5. Let it be x

x + 85 + 40 = 180

x + 125 = 180

x = 55 degrees

Step-by-step explanation:

Remeber it's the half of the number (N).

The value of hydronium ion concentration in the vinegar is 3.162×10^-3 (optionD)

pH is defined as the negative log of the hydrogen ion concentration. The range of pH extends from zero to 14. A pH value of 7 is neutral, because pure water has a pH value of exactly 7.

pH can also be defined as the measure of acidity and alkalinity of a substance.

pH = –log(H+)

Therefore (H+) = 10^-(pH)

For a pH of 2.5, the hydronium ion concentration

= 10^-2.5

(H+) = 0.003162 = 3.162×10^-3

Therefore hydronium ion concentration of the vinegar is 3.162×10^-3
