Answer:

C) 700 unit².

Step-by-step explanation:

Given : A rectangular prism .

To find : What is the surface area of the rectangular prism below.

Solution : We have given that a rectangular prism with

Length = 14 units,

Width = 12 units

Height = 7 units.

Surface area of rectangular prism = $2(length* width\ +\ height*width\ +\ height*length})$ .

Plugging the values

Surface area of rectangular prism = 2 ( 14* 12 + 7 *12 + 7 *14)

Surface area of rectangular prism = 2 ( 168 + 84 + 98)

Surface area of rectangular prism = 2 ( 350).

Surface area of rectangular prism = 700 unit².

Therefore, C) 700 unit².

Answer: $\Large\boxed{(-4,~-3)~\text{and}~(-2,~1)}$

Step-by-step explanation:

<u>Given the system of equation</u>

$1)~y=-(x+2)^2+1$

$2)~y=2x+5$

<u>Expand the parenthesis of the 1) equation</u>

$y=-(x+2)^2+1$

$y=-(x^2+4x+4)+1$

$y=-x^2-4x-4+1$

$y=-x^2-4x-3$

<u>Current System</u>

$1)~y=-x^2-4x-3$

$2)~y=2x+5$

<u>Substitute the y value of the 1) equation with the 2) equation</u>

$2x+5=-x^2-4x-3$

<u>Add ( x² + 4x + 3) on both sides</u>

$2x+5+(x^2+4x+3)=-x^2-4x-3+(x^2+4x+3)$

$2x+5+x^2+4x+3=0$

<u>Combine like terms</u>

$x^2+2x+4x+5+3=0$

$x^2+6x+8=0$

<u>Factorize the quadratic equation</u>

$(x+4)(x+2)=0$

$x=-4~\text{or}~x=-2$

<u>Substitute the x values into one of the equations to find the y value</u>

$y=2x+5$

$y=2(-4)+5=-8+5=-3$

$y=2(-2)+5=-4+5=1$

<u>Therefore, the two solutions are:</u>

$\Large\boxed{(-4,~-3)~\text{and}~(-2,~1)}$

Hope this helps!! :)

A manufacturing company is expected to pay a dividend of br. 1.25 per share at the end of the year (D1=br.1.25). The stock sells

Mama L [17]

Answer:

the equilibrium expected growth rate is 6.65%

Step by step Explanation:

We were given stock sold per share of $32.50

Dividend per share =$1.25

Required Return rate = 10.5%

Then we can calculate Percentage of Dividend for share as;

dividend of br. 1.25 per share at the end of the year (D1=br.1.25)

= 1.25×100= 125

Let the dividend percentage = y

stock sold per share × y= 125

125= 32.50y

y = 125/32.50

y= 3.85

y= 3.85*100%

Then the Dividend percentage = 3.85%

Growth rate=(required rate of return -Dividend percentage)

= 10.5 - 3.85 = 6.65

Therefore, the equilibrium expected growth rate is 6.65%

How do I factor 8x^2+12+48?

wolverine [178]

<h3><u>4(2x^2 + 3x + 12)</u></h3>

We can factor a 4 out of this expression.

4(2x^2 + 3x + 12)

Now that the expression is simplified, we can see if splitting the middle term is possible.

<em><u>Display factors of 24.</u></em>

1 * 24

-1 * - 24

2 * 12

-2 * -12

3 * 8

-3 * - 8

4 * 6

-4 * -6

All factors of 24 have been listed, and none of these digits satisfy the criteria.

Trinomial cannot be further factored.
