Answer: D) (x+1)(x + 2)(x-3)

This is because the roots are x = -1, x = -2 and x = 3
Simply get all the numbers to each side to have 0 on the right side

x = -1 turns into x+1 = 0
x = -2 turns into x+2 = 0
x = 3 turns into x-3 = 0

The three factors are (x+1), (x+2) and (x-3)
Which leads to (x+1)(x+2)(x-3)

Answer:

to serve hot chocolate to 14 people, you need:

7/6 cups boiling water

12.25 cups milk

2  5/8 teaspoons vanilla

7/4 half & half cream

To serve cookies to 14 people you need:

2.4 (rounded) cups flour

7/8 teaspoon baking soda

7/16 teaspoon baking powder

7/8 cup butter

21/16 cups white sugar

Step-by-step explanation:

The regular recipe for hot chocolate serves 4 people.  But 14 are being served; 14 is 3.5 times as much as 4, so multiply the measurements by 3.5.

The recipe for cookies makes 16 servings of 3 cookies (4 dozen total), so you must use slightly smaller quantities.  14 is 7/8 as much as 16, so just multiply the measurements by 7/8.

sergejj [24]

Answer:

Following are the solution to the given question:

Step-by-step explanation:

H_0: Management quality and corporate reputation are independent.  

H_1:  Management quality and corporate reputation are not independent.

Test statistic:

\to \chi^2 = \frac{\sum (O-E)^2}{E}

= 0.71429 + 0.0102 +2.8809+0.625+1.75 +0.3333    +0+3.2143+7.5\\\\= 17.02806

The critical \chi^2 fordf = (r-1)(c-1) = (3-1)(3-1)= 4 and \alpha = 0.05 is \chi^2= 9.4877

Test statistic:

17.02806 > 9.4877 therefore rejecting the null hypothesis H_0.

p-value= 0.001909

Interpretation:

There is no internal governance quality as well as the reputation of the organization.

The top and bottom margins of a poster are 6 ft and the side margins are each 8 ft. If the area of printed material on the poste
UNO [17]

Answer:

Dimension

Height =29.01

Breadth=38.70

Step-by-step explanation:

Printed area is =386 and margins as specified.

For printed area let height be x and breadth be y.

x*y=386 ⇒ y = \frac{386}{x}

Now considering the margins

Height = x+6+6=x+12

Weidth = \frac{386}{x} +8 +8= \frac{386}{x} + 16

Area of poster to be minimised =(x+12)(\frac{386}{x} + 16)

Differentiate above area with respect to x and equate to zero to find extrema.

 \frac{dA}{dx} = 16 -\frac{12*386}{x^{2} }=0

x=17.01

Now plug value of x in height and breadth

 Height =29.01

Breadth=38.70
