mEFG and mGFH is 61 and 119 respectively.

What is linear pair of angle?

Linear pair of angle are formed when two lines intersect each other at a single point and sum of angles of linear pair is always 180.

given, mEFG = 2n+17 and mGFH = 4n+31 and they both are linear.

Hence,

mEFG+mGFH = 180

2n+17+4n+31 = 180

6n+48=180

6n = 132

n = 22

hence, mEFG = 2(22)+17= 61 and mGFH = 4(22)+31 = 119

Given:

center of the circle = (3, -2)

radius = 4

To find:

the standard form of the equation of a circle

The standard form of the equation of circle is given as:

The equationof the circle in standard form:

3x+2y=10 This is the equation of the new line in standard form

Two parallel lines have the same slope,  to compute the slope (m) of the equation 3x+2y=19.  This can be obtained by converting the equation into slope-intercept form (i.e., y=mx+b, where m is the slope):

by subtracting 3x from both sides, and then simplifying:

3x+2y-3x=19-3x

     2y     =-3x+19

Then, let's divide both sides by 2, to obtain slope-intercept form:

      y      = (-3/2)x+(/2)     From this, we know that the slope (m) is -3/2

To determine the equation of the line we're being asked to solve for.  If we know the slope (in this case m=-3/2) along with any given point on the line ((x0,y0); in this case (4,1)), the equation of the line can be determined as y-y0=m(x-x0)

So substituting, the equation of the line is y-1=(-3/2)(x-5)

We now need to put this into standard form, with both x and y terms on the left side of the equation:

First, distribute the 3/2 on the right side:  y-1=(-3/2)x+(3/2)5  or y-1

= (-3/2)x+6

Next, add (3/2)x to both sides, add 1 to both sides, and simplify:

(3/2) x + y = 5

multiply both sides by 2, to eliminate the fraction (3/2): 3x+2y = 10 This is the equation of the new line in standard form

Applying the quotient rule, the derivative of the given function at x = 3 is of -2/3.

A quotient function is defined as follows:

i(x) = g(x)/f(x)

Applying the quotient rule, the derivative of the function defined above is of:

i'(x) = [g'(x)f(x) - f'(x)g(x)]/f(x)².

Hence, at x = 3, the numeric value of the derivative is given as follows:

i'(3) = [g'(3)f(3) - f'(3)g(3)]/f(3)².

Function f(x) is a linear function with slope of -3/2, hence:

Function g(x) is a linear function with slope of -1/2, hence:

Then the derivative is given as follows:

[tex]g^{\prime}(3) = \frac{-\frac{1}{2} \times \frac{3}{2} - \frac{3}{2} \times \frac{1}{2}}{\left(\frac{3}{2}\right)^2} = -\frac{\frac{6}{4}}{\frac{9}{4}} = -\frac{6}{9} = -\frac{2}{3}[/tex]

Hence the numeric value of the derivative at x = 3 is of -2/3.

Answer:

1 foot above the ground, positive 1

Step-by-step explanation:

you start at ground level let's call that 0

you go 10 down 0-10=-10

Now you climb up 20 feet so -10+20=10

Then you finally climb down 9 feet and 10-9=1

So you are one foot above the ground.

The solution to the rational inequality given in this problem is as follows:

(-1/2, 1/5].

The rational inequality is defined as follows:

[tex]\frac{3 - x}{2x + 1} \geq 2[/tex]

The first step to solve the inequality is isolate 0 on the right side of the inequality, hence:

[tex]\frac{3 - x}{2x + 1} - 2 \geq 0[/tex]

Then the least common multiplied is applied to represent the left side of the inequality as a single fraction, as follows:

[tex]\frac{3 - x - 2(2x + 1)}{2x + 1}\geq 0[/tex]

[tex]\frac{3 - x - 4x - 2}{2x + 1}\geq 0[/tex]

[tex]\frac{-5x + 1}{2x + 1}\geq 0[/tex]

There are two cases for the solution to the inequality:

The solution is the union of the solution of each of these cases.

-5x + 1 ≥ 0

-5x ≥ -1

5x ≤ 1

x ≤ 1/5

2x + 1 > 0 (only > as the denominator cannot be zero)

2x > -1

x > -1/2

The intersection of these solutions is given by the following interval:

(-1/2, 1/5].

-5x + 1 ≤ 0

-5x ≤ -1

5x ≥ 1

x ≥ 1/5

2x + 1 < 0

2x < -1

x < -1/2.

The intersection of these two cases is empty, hence the solution to the inequality is given by the following interval:

(-1/2, 1/5].

ANSWER

EXPLANATION

We want to find the domain and range of the function.

The domain of a function is the set of all input values of the function. Basically, the set of all x values of a function.

The range of a function is the set of all output values of the function. Basicallly, the set of all y values of a function.

To find the domain of the function, we have to look at the smallest and largest values of x.

The smallest value of x is -7.

The largest value of x is 3.

So, the domain is:

To find the range of the function, we have to look at the smallest and largest values of y.

The smallest value of y is -1.

The largest value of y is 9.

So, the range is:

Kira have $23 in his wallet.

Justin have $13 in his wallet.

Reuben have $46 in his wallet.

Given,

There are three persons, Kira, Justin, Reuben.

The total amount in their wallet = $82

The amount in Justin's wallet = x

The amount in Kira's wallet = x + 10

The amount in Reuben's wallet = 2(x + 10)

We have to find the amount in their wallets.

Here,

x + x + 10 + 2(x + 10) = 82

2x + 10 + 2x + 20 = 82

4x + 30 = 82

4x = 82 - 30

x = 52/4 = 13

Now,

The amount in Justin's wallet = x = $13

The amount in Kira's wallet = x + 10 = 13 + 10 = $23

The amount in Reuben's wallet = 2(x + 10) = 2(13 + 10) = 2 × 23 = $46

Answer:

Yes, 21.23 is a rational number.

[tex]21.23=\dfrac{2123}{100}[/tex]

Step-by-step explanation:

Terminating decimal numbers are decimals that have a finite number of decimal places.

A Rational Number is the division of an integer by another integer.

Therefore, 21.23 is a terminating decimal since it has a finite number of decimal places.

Let x be the rational number.

[tex]\implies x=21.23[/tex]

Multiply both sides by 100 so that the right side is an integer:

[tex]\implies 100x=2123[/tex]

Divide both sides by 100:

[tex]\implies x=\dfrac{2123}{100}[/tex]

(This fraction cannot be reduced any further).

Therefore, we have proved that 21.23 is a rational number.

Answer:

It is a rational number.

Step-by-step explanation:

Given value,

→ 21.23

Converting into rational number,

→ (21.23/1) × (100/100)

→ (21.23 × 100)/(1 × 100)

→ 2123/100

Hence, it is a rational number.

The probability of at most two hot peppers = 0.918

Total number of burritos ordered = 17

Number of burritos with hot peppers = 8

Number of burritos without hot pepper = 9

Number of burritos picked = 3

We need to find the probability of the event that at most two have hot peppers.

At most two have hot peppers means either there is one with hot pepper or there are two with hot pepper. So there should not be 3 burritos all with hot peppers.

Thus we can rewrite the probability that at most 2 out of 3 burritos are with hot peppers as, Total probability - the probability that all 3 burritos are with hot peppers.

So the probability that all three burritos are with hot peppers = P(3 with hot peppers)  = (8C3x9C0)/17C3

                       = 56 x 1/680

                       = 0.082

Then the probability that at most two burritos out of three are with hot peppers = 1 - P(3 with hot peppers)

              = 1 - 0.082

Use the rule that (A-B)^2 = A^2 - 2AB + B^2 to show (x-6)^2 = x^2-12x+36 is an identity. In this case, A = x and B = 6

You could also use the FOIL rule or the distributive property as two alternatives.
