2 X (12 + 9)
2 X 12 + 9

Answer:

8620.53

Step-by-step explanation:

πr2h=π·142·14

Volume ~ 8620.53

Answer:

2,744π units^3

Step-by-step explanation:

V = πr²h = π14²(14)

V = 196π(14) = 2744π ≈ 8,620.53

Answer:

What r the options so i can get an idea

Answer:

Step-by-step explanation:instead, try making the subscripts and superscripts stand out:

                         n-1

a    =  a         * r

 n         n-1

Believe me, it's worth the extra work to do this!!

Given the sequence   -3, -6, -12, -24, you can easily see that the first term,

a         is    -3.  The common factor is 2.  Note how (-3)*2=-6, and so on.

  1

So, a       = -3 and r=2.

        1

So the formula for this geometric sequence is  

                  n-1

a     =  -3*2

  n

Answer:

Option D:  is the function

Explanation: Let the general form of quadratic equation be  The function passes through the intercepts  and  and also passes though the point  Substituting the points ,  and  in the equation , we get,   -----------(1)  ----------(2)     -----------(3) Subtracting (1) and (2), we get,   -----------(4) Subtracting (2) and (3), we get,   ------------(5) Multiplying equation (4) by 5 and equation (5) by 4, to cancel the term b when adding, we get, Thus, the value of a is  Substituting  in equation (4), we get, Thus, the value of b is  Now, substituting the value of a and b in equation (1), we have, Thus, the value of c is  Now, substituting the value of a,b and c in the general formula , we get, Taking out the common term as -2 we get, Factoring , we get, Thus, the function is

Answer:

all them are multiplied by 0.50. 0.50x0.50= 0.25 and then 0.25x0.50= 0.125. y= X• 0.50

Answer:

[tex]\Huge\boxed{25.13ft^3}[/tex]

Step-by-step explanation:

Hello There!

It says the tree has a cone like structure

The formula for volume of a cone is

[tex]V=\pi r^2\frac{h}{3}[/tex]

where r = radius and h = height

note it says to use 3.14 for pi

so given the dimensions all we have to do is plug in the values into the formula

[tex]V=3.14*2^2*\frac{6}{3}\\2^2=4\\4*3.14=12.56\\\\\frac{6}{3} =2\\2*15.56=25.133[/tex]

Our last step is to round to the nearest foot

So we can conclude that the tree has a volume of 25.13ft³

- Hindu symbols

  - This will be a great start to a Hindu themed poster as the symbols mean a lot, and you could even put a message with the symbols

- Ganesha (sacred elephant) or Hanuman (The monkey god)

  - Putting sacred animals in the poster will really bring out the theme and idea of the poster itself.

- A temple

  - Putting a temple in the poster will overall represent the theme of this poster, as Hindu's spend a lot of time in their temple's

- Murti (statue or image of the god being worshipped0

  - To top it off add a religious symbol in there

Hinduism: A major religion started in South Asia, which was developed by Vedic Religion

95% of the Hindus live in India.

Over 900 million people are considered to be Hindu.

Hindus formed over 4,000 years ago.

Answer:

2x = 6

Step-by-step explanation:

Simplify the following algebraic expressions.

- 6x + 5 + 12x -6

2(x - 9) + 6(-x + 2) + 4x

3x2 + 12 + 9x - 20 + 6x2 - x

(x + 2)(x + 4) + (x + 5)(-x - 1)

1.2(x - 9) - 2.3(x + 4)

(x2y)(xy2)

(-x2y2)(xy2)

Solution

Group like terms and simplify.

- 6x + 5 + 12x -6 = (- 6x + 12x) + (5 - 6)

= 6x - 1

Expand brackets.

2(x - 9) + 6(-x + 2) + 4x = 2x - 18 - 6x + 12 + 4x

Group like terms and simplify.

= (2x - 6x + 4x) + (- 18 + 12) = - 6

Group like terms and simplify.

3x2 + 12 + 9x - 20 + 6x2 - x

= (3x2 + 6x2) + (9x - x) + (12 - 20)

= 9x2 + 8x - 8

Expand brackets.

(x + 2)(x + 4) + (x + 5)(- x - 1)

= x2 + 4x + 2x + 8 - x2 - x - 5x - 5

Group like terms.

= (x2 - x2) + (4x + 2x - x - 5x) + (8 - 5)

= 3

Expand and group.

1.2(x - 9) - 2.3(x + 4)

= 1.2x - 10.8 - 2.3x - 9.2

= -1.1x - 20

Rewrite as follows.

(x2y)(xy2) = (x2 x)(y y2)

Use rules of exponential.

= x3 y3

Rewrite expression as follows.

(-x2y2)(xy2) = -(x2 x)( y2 y2)

Use rules of exponential.

= - x3 y4

Simplify the expressions.

(a b2)(a3 b) / (a2 b3)

(21 x5) / (3 x4)

(6 x4)(4 y2) / [ (3 x2)(16 y) ]

(4x - 12) / 4

(-5x - 10) / (x + 2)

(x2 - 4x - 12) / (x2 - 2 x - 24)

Solution

Use rules of exponential to simplify the numerator first.

(a b2)(a3 b) / (a2 b3) = (a4 b3) / (a2 b3)

Rewrite as follows.

(a4 / a2) (b3 / b3)

Use rule of quotient of exponentials to simplify.

= a2

Rewrite as follows.

(21 x5) / (3 x4) = (21 / 3)(x5 / x4)

Simplify.

= 7 x

(6 x4)(4 y2) / [ (3 x2)(16 y) ]

Multiply terms in numerator and denominator and simplify.

(6 x4)(4 y2) / [ (3 x2)(16 y) ] = (24 x4 y2) / (48 x2 y)

Rewrite as follows.

= (24 / 48)(x4 / x2)(y2 / y)

Simplify.

= (1 / 2) x2 y

Factor 4 out in the numerator.

(4x - 12) / 4 = 4(x - 3) / 4

Simplify.

= x - 3

Factor -5 out in the numerator.

(-5x - 10) / (x + 2) = - 5 (x + 2) / (x + 2)

Simplify.

= - 5

Factor numerator and denominator as follows.

(x2 - 4x - 12) / (x2 - 2x - 24) = [(x - 6)(x + 2)] / [(x - 6)(x + 4)]

Simplify.

= (x + 2) / (x + 4) , for all x not equal to 6

Solve for x the following linear equations.

2x = 6
