If you dilate a figure with scale factor r = 1/2, what scale factor do you use to reverse that dilation and move it back?

Answer:

$25.44

Step-by-step explanation:

Although the starting price of the pair of jeans is $ 32, it is 25% off. Thus, 75% of its initial value (100-25) is being paid, with which the pre-tax price is determined as follows:

32 x 0.75 = X

24 = X

In turn, at that discounted price, 6% must be calculated as sales tax, with which the final price is determined through the following calculation:

24 x 1.06 = X

25.44 = X

Therefore, the price to pay for the pair of jeans is $ 25.44.

Answer:

y= -.25x+2.25

Step-by-step explanation:

Answer:

y = - [tex]\frac{1}{4}[/tex] x + [tex]\frac{9}{4}[/tex]  

Step-by-step explanation:

(-3, 3)

2y = 8x - 6 ⇔ y = 4x - 3

y - 3 = - [tex]\frac{1}{4}[/tex] (x + 3)

y = - [tex]\frac{1}{4}[/tex] x + [tex]\frac{9}{4}[/tex]

Answer:

The equilibrium quantity is 26.4

Step-by-step explanation:

Given

[tex]Q_d = 48 - 9P[/tex]

[tex]Q_s = 12 + 6P[/tex]

Required

Determine the equilibrium quantity

First, we need to determine the equilibrium by equating Qd to Qs

i.e.

[tex]Q_d = Q_s[/tex]

This gives:

[tex]48 -9P = 12 + 6P[/tex]

Collect Like Terms

[tex]-9P - 6P = 12 - 48[/tex]

[tex]-15P = -36[/tex]

Solve for P

[tex]P = \frac{-36}{-15}[/tex]

[tex]P =2.4[/tex]

This is the equilibrium price.

Substitute 2.4 for P in any of the quantity functions to give the equilibrium quantity:

[tex]Q_d = 48 - 9P[/tex]

[tex]Q_d = 48 - 9 * 2.4[/tex]

[tex]Q_d = 26.4[/tex]

Hence, the equilibrium quantity is 26.4

Complete question :

Find the standardized test statistic t for a sample with n = 15, x = 10, s = 0.8, H0: μ = 10.5. Round your answer to three decimal places.

Answer:

−2.420614

Step-by-step explanation:

Given that:

Given that:

n = 10

s = 0.8

X = 15

μ = 15.9

Using the relation :

(x - μ) / (s/√n)

(10 - 10.5) / (0.8/√15)

-0.9 / 0.2065591

= −2.420614

Hence, the standardized test statistic = −2.420614

I can't make a table but it would be like year to inches of percipitation Like:

Year | Precipitation (Inches)

2015 | 44.83

2016 | 45.18

2017 | 47.87

2018 | 35.73

2019 | 33.88

For the relationship just determine the pattern if it is addition subtraction e.t.c

Ex. The relationship is +30 or -56

Last but not least determine if it is a function pretty simple

Answer:

x = -47, y = 39

Step-by-step explanation:

2x+3y=23 →equation 1

3x+4y=15 →equation 2

by elimination method,

(2x+3y=23) × 4

(3x+4y=15) × 3

8x + 12y = 92

(-)      (-)       (-)

9x + 12y = 45

---------------------

-1x + 0    = 47

-x = 47

x = -47

substitute x=-47 in equation 1

2(-47) + 3y = 23

-94 + 3y = 23

3y = 23 + 94

3y = 117

y = 117/3

y = 39

therefore, x = -47 and y = 39

hope you understood ❤❤❤

Answer:

The domain (x values) is negative infinity to positive infinity since the graph keeps going in both directions ( left and right ) and the range (y values) is -1 to positive infinity since the graph starts at vertex (-1, -4) and continues infinitely upward.

Answer:

√10

Step-by-step explanation:

Pythagorean theorem. a^2+b^2=c^2.

In this case 9^2+b^2=√91^2. That equals 81+b^2=91. You isolate b^2, b^2=10. So b=√10.

Answer:

y = x + 7

Step-by-step explanation:

The equation of a line in slope - intercept form is expressed as y = mx+c

m is the slope

c is the intercept

Get the slope m;

m = tan theta

m = tan 45

m = 1

Get the intercept c;

Substitute m = 1 and (-2, 5) into the equation y = mx+c and get c;

5 = 1(-2)+c

5 = -2+c

c = 5+2

c = 7

Get the required equation;

y = 1(x)+ 7

y = x + 7

Hence the equation of the line is y = x+7

Answer:

[tex]x + 15 = 60[/tex]

[tex]x = 60 - 15[/tex]

Step-by-step explanation:

Given

[tex]Additional = 15[/tex]

[tex]Total = 60[/tex]

Required

What equation can be used to select the initial number of stickers

Represent the initial number of stickers with x

The equation can then be written as:

[tex]x + Additional = Total[/tex]

This gives:

[tex]x + 15 = 60[/tex] ---- This is one equation

Make x the subject

[tex]x = 60 - 15[/tex] --- This is another equation

Solving further for x

[tex]x = 45[/tex]

This implies that she started with 45 stickers

Answer:

no triangle can be formed with the given values (i.e 0 triangle).

Step-by-step explanation:

Given;

length of side a, = 10

length of side b, = 40

angle A, = 30°

Apply sine rule to determine the angle of the second side (B);

[tex]\frac{sin \ A}{a} = \frac{sin \ B}{b} \\\\\frac{sin \ 30^0}{10} = \frac{sin \ B}{40}\\\\sin \ B = 40(\frac{0.5}{10} )\\\\sin \ B = 2[/tex]

The maximum sine function is 1, there is no sine function that will be equal to 2, so there is no triangle that can be formed with the given values.

Answer:

The sample size is  [tex]n =  841 [/tex]

Step-by-step explanation:

From the question we are that

    The standard deviation is  [tex]\sigma = 5.6 \ hours[/tex]

     The margin of error is  [tex]E = 0.45[/tex]

From the question we are told the confidence level is  98% , hence the level of significance is    

      [tex]\alpha = (100 - 98) \%[/tex]

=>   [tex]\alpha = 0.02[/tex]

Generally from the normal distribution table the critical value  of  [tex]\frac{\alpha }{2}[/tex] is  

   [tex]Z_{\frac{\alpha }{2} } =  2.33[/tex]

Generally the sample size is mathematically represented as  

   [tex]n = [\frac{Z_{\frac{\alpha }{2} } *  \sigma }{E} ] ^2[/tex]

=>   [tex]n = [2.33 } *  5.6}{0.45} ] ^2[/tex]

=>   [tex]n =  841 [/tex]
