Answer:

Logarithmic functions are the inverses of exponential functions. The logarithmic function y=log(x)  is called the logarithmic function with base a .

When a constant c is added to the input of the parent function f(x)=loga(x), the result is a horizontal shift c units in the opposite direction of the sign on c. Our function is shifted 3 units to the right.

It is shifted 2 units vertical.(2 units down).

or

First, multiply the x by -3 and shift it 9 units to the right. Then, shift the function 1 unit down.

Using the concepts of the mean and of the mean absolute deviation, the correct option is given as follows:

Last month, the amount of rain that fell each day varied less than the month before.

In this problem, we have that:

Due to the lower mean absolute deviation combined with the higher mean, the amount varied less than the month before, hence the last option is correct.

The value of the unknown angle is as follows:

An angle bisector or the bisector of an angle is a ray that divides an angle into two equal parts

Therefore, CH bisects ∠GCD.

Therefore, it divide ∠GCD into two equal halves.

GC bisect ∠BGD.

Therefore, it divides ∠BGD into two equal halves.

Hence,

m∠BGC = m∠CGF

Therefore,

m∠BGC  = 7x - 2

m∠CGF = 8x - 8

7x - 2 = 8x - 8

7x - 8x = -8 + 2

-x = -6

x = 6

Therefore,

m∠BGF = 7x -2 + 8x - 8

m∠BGF = 15x - 10

m∠BGF = 15(6) - 10

m∠BGF = 90 - 10

Therefore,

m∠BGF = 80 degrees

Equation of line in slope intercept form: y = mx +c

Pick any two points from the table and find the slope.

 (-2 , 9) ; (-1,7)

  [tex]\sf \boxed{\bf Slope= \dfrac{y_2-y_1}{x_2-x_1}}[/tex]

              [tex]\sf = \dfrac{7-9}{-1-[-2]}\\\\=\dfrac{-2}{-1+2}\\\\=\dfrac{-2}{1}\\\\=-2[/tex]

y = -2x + c

Substitute (-2,9) in the above equation and find the y-intercept 'c'.

      9 = -2*(-2) +c

      9 = 4 + c

 9 - 4 = c

        c = 5

Equation of line:

Medical insurance Jessica pays biweekly is $196.58 or 197 dollars.

Dental insurance Jessica pays biweekly is $22.3125 or 22 dollars.

Janice:

Medical insurance costs $6,740 annually

Dental costs $630

Solution:

Jessica:

70% of medical insurance = 70/100*6,740

= 674 * 7

=  $4,718/annum.

85% of dental insurance = 85/100 * 630

= 63 * 8.5

=  $535.5/annum

Medical insurance Jessica pays per month = 4,718/12 = $393.16

Medical insurance Jessica pays biweekly = 393.16/2 = $196.58 or $197

Dental insurance Jessica pays per month = 535.5/12= $44.625

Dental insurance Jessica pays biweekly = 44.625/2 = $22.3125 or $22.

Value of 'a' for the given statement  the negative a minus four sevenths equals two thirds for a after solving is equal to negative 26 over 21.

As given in the question,

Given statement :

Negative a minus four sevenths equals two thirds for a

Represent the statement in equation form :

-a -(4 / 7) = ( 2 / 3 )

Solve by adding both the side ( 4 / 7 ) we get,

-a - (4 /7) + (4 /7) = (2/3) +(4/7)

⇒ -a = (2/3) + (4/7)

least common multiple of 3 and 7 is 21.

-a = ( 14 /21) + (12 /21)

⇒ -a = 26 /21

⇒ a = -26/21

Therefore, value of 'a' for the given statement  the negative a minus four sevenths equals two thirds for a after solving is equal to negative 26 over 21.

The line which is parallel to the given line is 2x- y= 0 or y= 2x.

The given line y= 7+ 2x

this is written in the form y= mx +c where if we compare these two equations we get m= 2

Now consider a point which passes through the origin (0,0)

Thus y-y₁= m(x-x₁)

y- 0 = 2 ( x- 0)

y= 2x or 2x- y= 0

Thus, the line which is parallel to the given line is 2x- y= 0.

The rules of Perfect Square Trinomial are, an expression obtained from the square of the binomial equation is a perfect square trinomial. If a trinomial is in the form [tex]ax^{2} +bx+c[/tex] is said to be a perfect square, if and only if it satisfies the condition [tex]b^{2} = 4ac[/tex].

Perfect square trinomials are algebraic expressions with three terms that are obtained by multiplying a binomial with the same binomial. A perfect square is a number that is obtained by multiplying a number by itself. Binomials are algebraic expressions consisting of just two terms that are either separated by a positive (+) or a negative (-) sign. Similarly, trinomials are algebraic expressions consisting of three terms. When a binomial consisting of a variable and a constant is multiplied by itself, it results in a perfect square trinomial having three terms. The terms of a perfect square trinomial are separated by either a positive or a negative sign.

A perfect square trinomial is defined as an algebraic expression that is obtained by squaring a binomial expression. It is of the form [tex]ax^{2} +bx+c[/tex]. Here a, b, and c are real numbers and a ≠ 0. For example, let us take a binomial (x+4) and multiply it to (x+4). The result obtained is [tex]x^{2} +8x+16[/tex]. A perfect square trinomial can be decomposed into two binomials and the binomials when multiplied with each other gives the perfect square trinomial.

Therefore,

An expression obtained from the square of the binomial equation is a perfect square trinomial. If a trinomial is in the form [tex]ax^{2} +bx+c[/tex] is said to be a perfect square, if and only if it satisfies the condition [tex]b^{2} = 4ac[/tex].

The constant of proportionality in cups of water to minute is 80 cups/min

Here we have the proportional relation:

y = k*x

Where y is the number of cups and x the time in seconds, then:

y/x = k

Replacing the values we know:

y = 8 cups.

x = 6 seconds.

We can get the value of k, the constant of proportionality, but first, let's write the time in minutes.

x = 6 seconds

remember that 1 min = 60 sec, then:

6 sec = (6/60) min = 0.1 min

So the constant of proportionality is:

k = 8cups/0.1 min = 80 cups/min

Since both angles are the same, x has a value of 11

Angles are formed when two or more lines intersect. This in other words means that angles is the measure of space between the intersection of rays or lines

The given parameters are

m∠PQS=(3x−3)° and m∠RQS=(x+19)°.

From the question, the measures of both angles are the same

This means that

m∠PQS=(3x−3)° = m∠RQS=(x+19)°.

So, we have the following equation

3x − 3 = x + 19

Collect the like terms in the equation

So, we have the following equation

3x - x = 3 + 19

Evaluate the like terms in the equation

So, we have the following equation

2x = 22

Divide both sides by 2

So, we have the following equation

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The probability that we find a value X lower than x is given by the following formula.

[tex]P(X\leq x)[/tex] = x-a / b-a

Uniform distribution from 0 to 4.8 seconds.
