X2−3x−10 ( x - 4 ) ( x + 2 ) ( x - 4 ) ( x + 2 ) ( x - 5 ) ( x + 2 ) ( x - 5 ) ( x + 2 ) ( x + 8 ) ( x - 1 ) ( x + 8 ) ( x - 1 )
loris [4]

Answer:

(x+2)(x-5)

Step-by-step explanation:

Given the expression X^2−3x−10, we are to factorize it;

On factorizing;

= x² - 5x + 2x - 10

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

= (x+2)(x-5)

Hence the factored form of the expression is (x+2)(x-5)

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.

a cone has a volume of 1230.88 units cubed and a diameter of 14 units what is the height of the cone use 3.14 for pi
ANEK [815]

Answer:

h= 24

Step-by-step explanation:

v = \pi {r}^{2}  \frac{h}{3}

r =  \frac{d}{2}

r =  \frac{14}{2}

r= 7

1230.88=3.14×7^2×h/3

1230.88= 153.86h/3

h=1230.88/153.86

h= 24

The volume is ___ cubic cm.
Effectus [21]

Answer:

Step-by-step explanation:

This looked very difficult UNTIL I looked at the pyramid as ONE HALF of a larger pyramid!    Image a mirror image of the pyramid creating a pyramid that is 12 cm of the front and back side and 6 cm on the left and right edge.

IT IS NO LONGER A SQUARE PYAMID so you need the volume for a rectanglar pyramid

The volume of a square pyramide is .....    

      V = side² × (height / 3)

The volume of a rectangular pyramide is .....    

      V = base area × (height / 3)      

         =  length × width × (height / 3)

         =  12 × 6 × 10 / 3    cm³        BUT REMEMBER we want only HALF of the

         = [12 × 3 × 10] divide by 2 cm³          Rectangular pyamid

Volume of the image shown in the diagram is ....

          = 360 / 2  cm³

          = 180 cm³    <-----------------  Final Answer
