Answer:

  3. yes: a[1] = -8, a[n] = a[n-1] +7; an = -8 +7(n -1)

  4. no (no common difference)

Step-by-step explanation:

An arithmetic sequence is one in which each term has the same difference from the term before it.

__

3. -1 -(-8) = 7; 6 -(-1) = 7; 13 -6 - 7. The differences are all 7, so the terms have a common difference. This sequence is arithmetic.

The general form of the recursive rule for an arithmetic sequence with first term a1 and common difference d is ...

  a[1] = a1; a[n] = a[n-1] +d . . . . . recursive rule

  a[1] = -8; a[n] = a[n-1] +7

The general form of the explicit rule for an arithmetic sequence is ...

  an = a1 +d(n -1)

  an = -8 +7(n -1)

__

4. The differences are ...

  8 -1 = 7; 27 -8 = 19; 81 -27 = 54 . . . the differences are not common

This sequences is not arithmetic.

Answer: [tex]f= \frac{ C -4h -5p }{7}[/tex]

Isolate f

Subtract 5p from both sides

Subtract 4h from both sides

Divide both sides by 7

Si hacen un reparto directamente proporcional a los capitales aportados, a María le corresponden $4444,44, a Pepe $5555,55, a Ana $6666,66 y a Miguel $13333,33.

Dado que María, Pepe, Ana y Miguel crean una empresa en sociedad aportando un capital inicial de 4.000, 5.000, 6.000 y 12.000 dólares, respectivamente, y las utilidades netas en el primer año fueron de 30.000 dólares, para determinar qué cantidad corresponde a cada uno si hacen un reparto directamente proporcional a los capitales aportados se debe realizar el siguiente cálculo:

Por lo tanto, si hacen un reparto directamente proporcional a los capitales aportados, a María le corresponden $4444,44, a Pepe $5555,55, a Ana $6666,66 y a Miguel $13333,33.

Answer:

a) a +b= 13, ab= 40

b) length= 8m, width= 5m

Step-by-step explanation:

Perimeter of rectangle= 2(length +width)

Area of rectangle= length ×width

a) Perimeter= 26m

2(a +b)= 26

Divide both sides by 2:

a +b= 26 ÷2

a +b= 13 ----- (1)

Area= 40m²

ab= 40 ----- (2)

b) From (1): a= 13 -b ----- (3)

Substitute (3) into (2):

(13 -b)(b)= 40

Expand:

13b -b²= 40

b² -13b +40= 0

Factorise:

(b -5)(b -8)= 0

b -5= 0 or b -8= 0

b= 5 or b= 8

Substitute into (3):

a= 13 -5 or a= 13 -8

a= 8 or a= 5

Since the length is usually the longer side of the rectangle, the length and the width of the rectangular garden is 8m and 5m respectively.

Answer:

Step-by-step explanation:

Perimeter = 2length + 2 width

   2a + 2b = 26 m

Divide the equation by 2

[tex]\dfrac{2a}{2}+\dfrac{2b}{2}=\dfrac{26}{2}\\\\[/tex]

a + b  = 13         --------------(I)

a = 13 -b

Area = length *width

a*b = 40 sq.m

ab = 40   ----------------(II)

Plugin a = 13 -b in the equation (II)

(13 - b)*b = 40

13*b - b*b = 40

13b - b² = 40

0 = 40 + b² - 13b

b² - 13b + 40 = 0

Sum = - 13

Product  = 40

Factors = (-8) , (-5)      {-8 + (-5) = -13 & (-5)*(-8) = 40}

b² - 8b - 5b + (-8)*(-5) = 40

b(b - 8) - 5(b - 8)= 0

( b - 8) (b - 5) = 0

b - 8 =0     ; b -5 =0

b= 8   ; b = 5

Length = 8 cm

Width = 5cm

Additional comments

A graphing calculator provides a quick and easy solution to a system of equations. There are many calculators and apps and on-line sites that can solve a system of equations for you.

For the pair of equations in part A, you can eliminate the y-variable by adding 2 times the first equation to 3 times the second equation:

  2(2x -3y) +3(3x +2y) = 2(12) +3(31)   ⇒   13x = 117   ⇒   x = 9

Substituting in the first equation gives ...

  2(9) -3y = 12   ⇒   6 -y = 4   ⇒   y = 2

__

For the paired equation in part B, the ratio of the x- and y-coefficients is 6/-9 = -2/3, the same as it is for the given equation. The constants are different (even after dividing the second equation by 3), so the lines are parallel (not coincident). This means the system of paired equations has no solution.

Looks like the equation is

[tex]g(x) + x \cos(g(x)) = x^3[/tex]

Differentiate both sides with respect to x, using the chain rule on the left side:

[tex]g'(x) + \cos(g(x)) - x \sin(g(x)) g'(x) = 3x^2[/tex]

Solve for g'(x) :

[tex]g'(x) (1 - x \sin(g(x))) = 3x^2 - \cos(g(x)) \\\\ g'(x) = \dfrac{3x^2 - \cos(g(x))}{1 - x \sin(g(x))}[/tex]

When x = 0, we have

[tex]g'(0) = \dfrac{0-\cos(g(0))}{1-0\sin(g(0))} = \boxed{-\cos(g(0))}[/tex]

(This is all you can say without providing the value of g (0).)

Step-by-step explanation:

Answer:

simply 8c = 128

For 9 Kg ground ginseng needed =304.7

For  9 Kg golden chai needed =146.2

For the blend =225.5

It is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.

First, let us make a note of the information we have. There are 5 ice-creams. 5 ice-creams cost $125.

Step 1: Let’s find the cost of 1 ice cream. In order to do that, divide the total cost of ice-creams by the total number of ice-creams. The cost of 1 ice-cream = Total cost of ice-creams/Total number of ice-creams = 125/5 = 25. Therefore, the cost of 1 ice cream is $25.

Step 2: To find the cost of 3 ice-creams, multiply the cost of 1 ice cream by the number of ice-creams. The cost of 3 ice-creams is cost of 1 ice-cream × number of ice-creams = 25 × 3 = $75. Finally, we have the cost of 3 ice-creams i.e. $75.

given:

The blend, which costs $25.05 per kilogram.

For 9 Kg ground ginseng needed = 33.85* 9 =304.65 = 304.7

For  9 Kg golden chai needed = 16.25 * 9= 146.25=146.2

For the blend = 25.05 * 9= 225.45=225.5

Answer:

100

Step-by-step explanation:

16x + 19x + 5 = 180   {co-interior angles are supplementary}

Combine like terms;

35x + 5 = 180

Subtract 5 from both sides

35x = 180 - 5

35x = 175

Divide both sides by 35

x = 175/35

x = 5

19x + 5 = 19*5 + 5

           = 95 + 5

           = 100

Answer:

100⁰

Step-by-step explanation:

co interior angles add up to 180⁰

so l9x+5+16x=180⁰

35x+5⁰=180⁰

35x=180⁰-5⁰

35x=175⁰

Divide both side by the co-efficient of x which is 35

35x/35=175⁰/35⁰

x=5

Now to find the value of 19x+5,we have to substitute any x in it by 5

so 19x+5

19(5)+5

95+5

100⁰
