Answer:

[tex]\frac{r^{15}}{512}[/tex]

Step-by-step explanation:

Given

[tex](8r^{-5})^{-3}[/tex]

Required

Simplify

This can be simplified using the following law of indices;

[tex](ab)^n = a^{n}b^{n}[/tex]

The equation becomes

[tex](8^{-3})(r^{-5})^{-3}[/tex]

Express [tex]8^{-3}[/tex] as a fraction

[tex](\frac{1}{8^{3}})(r^{-5})^{-3}[/tex]

Simplify [tex]8^3[/tex]

[tex](\frac{1}{8*8*8})(r^{-5})^{-3}[/tex]

[tex](\frac{1}{512})(r^{-5})^{-3}[/tex]

The expression can further be simplified using the following law of indices;

[tex](a^m)^n = a^{mn}[/tex]

[tex](\frac{1}{512})(r^{-5})^{-3}[/tex] becomes

[tex](\frac{1}{512})(r^{-5*-3})[/tex]

[tex](\frac{1}{512})(r^{15})[/tex]

[tex]\frac{r^{15}}{512}[/tex]

Hence, the solution to [tex](8r^{-5})^{-3}[/tex] is [tex]\frac{r^{15}}{512}[/tex]

x = 15

Step-by-step explanation:

Using Pythagorean Theorem

=> [tex]c^2 = a^2+b^2[/tex]

Where c= x, a = 12, b = 9

=> [tex]x^2 = (12)^2+(9)^2[/tex]

=> [tex]x^2 = 144+81[/tex]

=> [tex]x^2 = 225[/tex]

Taking sqrt on both sides

=> x = 15

Answer:

The equation of the line that represents the landscaping company's fixed reservation rate and charge per hour is y=15.9x+77.025

Step-by-step explanation:

The first bill amount for 2.75 hours of  landscaping work = $120.75

The second bill amount for 5.25 hours of  landscaping work = $160.50

No we are supposed to find the equation of the line that represents the landscaping company's fixed reservation rate and charge per hour

So, we will us two point slope form to find the equation:

Formula : [tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

[tex](x_1,y_1)=(2.75,120.75)\\(x_2,y_2)=(5.25,160.50)[/tex]

Substitute the values in the formula

[tex]y-120.75=\frac{160.50-120.75}{5.25-2.75}(x-2.75)\\y=15.9x+77.025[/tex]

Hence  the equation of the line that represents the landscaping company's fixed reservation rate and charge per hour is y=15.9x+77.025

Answer:

V =2197 ft^3

Step-by-step explanation:

The volume of a cube is given by

V = s^3 where s is the length of a side

V = 13^3

V =2197 ft^3

Answer:

Volume = 2197ft³

Answer:

see explanation

Step-by-step explanation:

Given

2BD = 7BT , then

2(d - b ) = 7(t - b) ← distribute both sides

2d - 2b = 7t - 7b ( add 7b to both sides )

2d + 5b = 7t, thus

2[tex]\left[\begin{array}{ccc}10.5\\10\\\end{array}\right][/tex] + 5[tex]\left[\begin{array}{ccc}0\\3\\\end{array}\right][/tex] = 7t

[tex]\left[\begin{array}{ccc}21\\20\\\end{array}\right][/tex] + [tex]\left[\begin{array}{ccc}0\\15\\\end{array}\right][/tex] = 7t

[tex]\left[\begin{array}{ccc}21\\35\\\end{array}\right][/tex] = 7t , thus

t = [tex]\frac{1}{7}[/tex][tex]\left[\begin{array}{ccc}21\\35\\\end{array}\right][/tex] = [tex]\left[\begin{array}{ccc}3\\5\\\end{array}\right][/tex]

Hence T = (3, 5 )

Answer:

Please see the attached pictures for the full solution.

We reject x= -3 since x has to be between x=0 and x=10.5 since T lies on line BD.

We reject y= 1 since the y value has to be between 3 and 10 for T to lie on line BD.

Useful formula:

gradient=(y1-y2)/(x1-x2)

Further explanation:

1st picture, from line 12 to 13: cross multiply

line 14: expand

line 15: bring 9 over (or +9 on both sides)

line 16: ÷3 throughout

last picture: we have to show '(reject)' because whenever we introduce a square root, there must be a '±' sign.

Answer:

I think it's A but I could be wrong

Answer: B

Step-by-step explanation:

A graph or table is a function if it passes the vertical line test. That means, each x and only 1 y. One x cannot have more than 1 y because, that means it does not pass the veritcal line test. In the vertical line test, the vertival line only passes through 1 point, not 2. Since we know that this graph does not pass the vertical in test, we can eliminate C and D. We can eliminate A because 2 y-values can be the same as lone as there have different x. B fits the description of what we see on the table. Therefore, the answer is B.

Answer:

x < -16/3 or x > 4

Step-by-step explanation:

This is split into two inequalities: 3x + 2 > 14 and -(3x + 2) > 14.

3x + 2 > 14

3x > 12

x > 4

-(3x + 2) > 14

3x + 2 < -14

3x < -16

x < -16/3

Answer:

[tex]x > 4[/tex]

Step-by-step explanation:

Move the constant to the right-hand and change its sign:

[tex]3x > 14 - 2[/tex]

Subtract the number:

[tex]3x > 12[/tex]

Divide both sides of the inequality by 3:

[tex]3 \div 12 = 4[/tex]

Therefore, the answer will be x > 4.

Answer:

10 crows and 5 ground hogs

Step-by-step explanation:

10 ×2 is 20 because crows have 2 legs then we do 5×4 which is 20 because ground hogs have 4 legs 10 +5 equals 15 because each animal has one head

Answer:

(1) N or n = 20

(2) [tex]\bar X \text{ or } \mu[/tex] = 43.4

(3) σ = 9.78 and s = 10.04.

Step-by-step explanation:

We are given with the following data set below;

{51, 48, 42, 43, 48, 48, 46, 15, 29, 45, 47, 55, 46, 35, 47, 48, 54, 26, 53, 42}

(1) As we can see in the above data that there are 20 data values in our data set which means that the value of N or n (numner of observations) is 20.

(2) The formula for calculating Mean of the data, i.e. [tex]\bar X \text{ or } \mu[/tex] is given by;

        Mean  =  [tex]\frac{\sum X}{n}[/tex]

              =  [tex]\frac{51 +48+ 42+ 43+48+48+ 46+ 15+ 29+ 45+ 47+ 55+ 46+ 35+ 47+ 48+ 54+ 26+ 53+ 42}{20}[/tex]

              =  [tex]\frac{868}{20}[/tex]  = 43.4

So, the value of [tex]\bar X \text{ or } \mu[/tex] is 43.4.

(3) The formula for calculating population standard deviation ([tex]\sigma[/tex]) is given by;

        Standard deviation, [tex]\sigma[/tex] =  [tex]\sqrt{\frac{\sum (X - \bar X)^{2} }{N} }[/tex]

             =  [tex]\sqrt{\frac{(51-43.4)^{2}+(48-43.4)^{2}+.......+(42-43.4)^{2} }{20} }[/tex]

             =  9.78

Similarly, the formula for calculating sample standard deviation (s) is given by;

        Sample Standard deviation, s =  [tex]\sqrt{\frac{\sum (X - \bar X)^{2} }{n-1} }[/tex]

             =  [tex]\sqrt{\frac{(51-43.4)^{2}+(48-43.4)^{2}+.......+(42-43.4)^{2} }{20-1} }[/tex]

             =  10.04

Answer: Slope 1/4  therefore slope of new line would be -1/4

Step-by-step explanation:

The points of the inverse of the line provided on the graph are as under:

x=2,y=5

x=0,y=-5

x=1,y=0

It means interchanging the values of x with the values of y and form a line which is known a inverse of a line.

firstly point out the points from the graph given in the question as in the graph1 below

now by interchanging the values we get the values of inverse of the line as in the graph 2

By plotting these points on the graph we get the inverse of the line which is in the graph 3
