Answer:

2nd option

Step-by-step explanation:

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

leave the first fraction, change division to multiplication, turn the second fraction upside down , that is

= [tex]\frac{x+1}{x(x-1)}[/tex] × [tex]\frac{3(x-1)}{4}[/tex] ← cancel (x - 1) on numerator / denominator

= [tex]\frac{x+1}{x}[/tex] × [tex]\frac{3}{4}[/tex]

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

= [tex]\frac{3x+3}{4x}[/tex]

Answer:

h = 110°

Step-by-step explanation:

1) A pentagon has 5 sides that sum up to 540°. We know it is 540° because of this formula that is used to find the sum of the interior angles of any polygons. n is the number of sides.

= (n - 2) x 180

= (5 - 2) x 180

= 3 x 180

= 540°

2) We can now set up an equation.

70 + 100 + 120 + 140 + h = 540

430 + h = 540

h = 540 - 430

h = 110°

Given formula: [tex]\sf A_n= -4(2)^{n-1}[/tex]

simplify substitute the number of term by replacing n

Find first five terms:

[tex]\sf A_1= -4(2)^{1-1}[/tex]  ⇒  [tex]\sf A_1= -4[/tex]

[tex]\sf A_2= -4(2)^{2-1}[/tex]  ⇒  [tex]\sf A_2= -8[/tex]

[tex]\sf A_3= -4(2)^{3-1}[/tex]  ⇒  [tex]\sf A_3= -16[/tex]

[tex]\sf A_4= -4(2)^{4-1}[/tex]⇒  [tex]\sf A_4= -32[/tex]

[tex]\sf A_5= -4(2)^{5-1}[/tex]⇒  [tex]\sf A_5= -64[/tex]

Tenth term:

[tex]\sf A_{10}= -4(2)^{10-1}[/tex]   ⇒  [tex]\sf A_{10}= -2048[/tex]

Answer:

[tex]\sf a_1=-4\\a_2=-12\\a_3=-20\\a_4=-28\\a_5=-36\\a_{10}=-76[/tex]

Step-by-step explanation:

[tex]\textsf{Given sequence}: \sf a_n=-4(2n-1)[/tex]

This formula is for the nth term of the sequence.

Therefore, to find any term of the sequence, substitute the position of the term you wish to find as n.

For example, to find the 10th term, substitute n = 10 into the formula:

[tex]\begin{aligned}\sf a_{10} & =-4[2(10)-1)]\\ & = -4(20-1)\\ & = -4(19)\\ & = -76\end{aligned}[/tex]

To find the first 5 terms, substitute n = 1 through n = 5 into the formula:

[tex]\sf a_1=-4[2(1)-1]=-4(2-1)=-4(1)=-4[/tex]

[tex]\sf a_2=-4[2(2)-1]=-4(4-1)=-4(3)=-12[/tex]

[tex]\sf a_3=-4[2(3)-1]=-4(6-1)=-4(5)=-20[/tex]

[tex]\sf a_4=-4[2(4)-1]=-4(8-1)=-4(7)=-28[/tex]

[tex]\sf a_5=-4[2(5)-1]=-4(10-1)=-4(9)=-36[/tex]

Answer: So therefore your answer would be 7 3/4

Step-by-step explanation: Okay so sun's you are trying to increase the recipe by four times That means you need to do what the recipe calls for four times and times what the recipe calls for by four or how many times larger you want to make it. So first we would do 3/4 X 4 = 12/16 And then from there we need to simplify And for this I'm pretty for sure lol We are going to divide the top by three and then the bottom by four. So then it goes back to 3/4 and seven cups I'm pretty sure.

Answer:

[tex]\cfrac{\left(x+8\right)\left(x-8\right)}{x^2+13}[/tex]

Step-by-step explanation:

[tex]\cfrac{\left(x+8\right)\left(x+2\right)\left(x-8\right)}{\left(x+2\right)\left(x^2+13\right)}[/tex]

[tex]\cfrac{\left(x+8\right)\left(x-8\right)}{x^2+13}[/tex]

[tex]y = \stackrel{\stackrel{m}{\downarrow }}{5}x-3\qquad \impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}[/tex]

well, what's the equation of a line whose slope is 5 and passes through (-2 , -13) ?

[tex](\stackrel{x_1}{-2}~,~\stackrel{y_1}{-13})\qquad \qquad \stackrel{slope}{m}\implies 5 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{(-13)}=\stackrel{m}{5}(x-\stackrel{x_1}{(-2)})\implies y+13=5(x+2)[/tex]

Answer:

The last option

Step-by-step explanation:

There are 42 species in the sample

the proportions are:

frogs = 18/42 = 3/7

lizards = 18/42 = 3/7

worms = 6/42 = 1/7

The number of frogs and lizards is the same and exceeds that of worms

The only option that meets these proportions is the last

Answer:

Equations II and IV

Step-by-step explanation:

See attached image.

Find the equation of the line in the form of y=mx+b, where m is the slope and b the y-intercept.  Pick any two points to calculate the Rise/Run, or slope, of the line, as shown.  The y-intercept, b, is the value of y when x=0.  Rearrange the resulting equation, as necessary, to see if it matches any of the options.  In option IV, I rearranged the answer, as it was easier to get it into the desired form of y=mx+b.

As shown, equations II and IV both match.

Answer:

70 - 5√10 ft²

Explanation:

Perimeter is the distance around a two-dimensional shape.

                       area of rectangle: length x width

Here given:

length: (3√2 + 4√5) ft

width: (-5√2 + 5√5) ft

Solve for perimeter:

length x width

(3√2 + 4√5) x (-5√2 + 5√5)

apply distributive method

(3√2)(-5√2) + (3√2)(5√5) + (4√5)(-5√2) + (4√5)(5√5)

multiply

-15(2) + 15√10 -20√10 + 20(5)

Answer:

reggie made an error

the correct scale factor is 2/3

Step-by-step explanation:

we want to get from A to A', B to B', and ultimately C to C'

to get there, we must multiply each value in each point by the scale factor.

let's start out with reggie's scale factor. he multiplies each value in C by 3/2 to get to C'. we can try this out with one point, e.g. A

for A: 3/2 * (-12, -6) = (-18, -9). this is not A' = (-8, -4)! thus, 3/2 cannot be the scale factor

now, onto hillary's scale factor of 2/3

for A: 2/3 * (-12, -6) = (-8, -4). this is A'! thus, hillary is correct and reggie made an error

the correct scale factor is thus hillary's: 2/3

Answer:

A. (0,2) (4,2) (0,0)

b. (-2,0) (-2,-4) (0,0)

c. (0,2) (4,2) (0,0)

d. (0,2) (-4,2) (0,0)

These pointed are reflected into y-axis.

The drawing will take time to be drawn, that's why i only have written the points.

Answer And Step-by-step explanation:

1. b + 59 = 90

90 - 59 =b

⇒ b = 31

3. 29 + b = 90

90 - 29 = b

⇒ b = 61

5. 23 + b = 90

90 - 23 = b

⇒ b = 67

7. 32 + b = 90

90 - 32 = b

⇒ b = 58

18. 88 + b = 180

180 - 88 = 92

⇒ b = 92

20. 96 + b =180

180 - 96 = b

⇒ b = 84

22. 73 + b = 180

180 - 73 = b

⇒ b = 107

24. 91 + b = 180

180 - 91 = b

⇒ b = 89

The table is a linear regression model, and the equation of the regression model is y = 0.24x + 0.77

See attachment for the required scatter plot

From the attached scatter plot, we can see that the points are almost on a straight line

Hence, the best model that fits the scatter plot is a linear model

Using a graphing calculator, we have the following calculation summary:

The regression equation is represented as:

y = bx + a

So, we have:

y = 0.23929x + 0.77143

Approximate

y = 0.24x + 0.77

Hence, the equation of the regression model is y = 0.24x + 0.77

Answer:

Step-by-step explanation:

The range = 2 = (greatest number in the set) - (lowest number in the set)

→ If we took x < 1 then the range would be 3 - x > 3 - 1 then 3 - x > 2 which is impossible ,therefore x could not be less than 1

→ If we took x > 3 then the range would be x - 1 > 3 - 1 then x - 1 > 2 which is impossible ,therefore x could not be higher than 3

1 ≤ x ≤ 3

then

x = 1 or x = 2 or x = 3

Answer:

The missing side length is 5.7

Step-by-step explanation:

Using the pythagoream theorem you can find the missing side length of a right triangle.

The formula is [tex]a^{2} + b^{2} = c^{2}[/tex] where a and b are the lengths of the triangle legs and c is the hypotenuse.

So yours would be:

[tex]7^{2} + x^{2} = 9^{2}[/tex]

Square the numbers:

[tex]49 + b^{2} = 81[/tex]

Isolate b:

[tex]b^{2} = 32[/tex]

Square root both sides:

[tex]b=\sqrt{32}[/tex]

Simplify:

[tex]\sqrt{32} = 5.7[/tex]
