The number rounded to the nearest sum is 105 due to the fact that the decimal point is lower then 5
Answer:
a = 10 cm
Step-by-step explanation:
Area of triangle, A = 51 cm²
base, b = 10.2 cm
Let height of triangle be a cm
<em><u>Formula:-</u></em>
![A=\dfrac{1}{2}\times a\times b](https://tex.z-dn.net/?f=A%3D%5Cdfrac%7B1%7D%7B2%7D%5Ctimes%20a%5Ctimes%20b)
![51=\dfrac{1}{2}\times a\times 10.2](https://tex.z-dn.net/?f=51%3D%5Cdfrac%7B1%7D%7B2%7D%5Ctimes%20a%5Ctimes%2010.2)
![a=\dfrac{51\times 2}{10.2}](https://tex.z-dn.net/?f=a%3D%5Cdfrac%7B51%5Ctimes%202%7D%7B10.2%7D)
![a=10](https://tex.z-dn.net/?f=a%3D10)
hence, the missing length is 10 cm
Answer:
The roots of the given equation is x=4,3i,-3i
Step-by-step explanation:
The given cubic equation is
![y=x^3-4x^2+9x-36](https://tex.z-dn.net/?f=y%3Dx%5E3-4x%5E2%2B9x-36)
To find the roots we have to equate the equation to zero
ie, ![x^3-4x^2+9x-36=0](https://tex.z-dn.net/?f=x%5E3-4x%5E2%2B9x-36%3D0)
It can be done by using Synthetic division method
Therfore [tex](x-1) is not a factor or root
now put x=-1
Therfore [tex](x-1) is not a factor or root
similarly let x=2,-2,3,-3 all not equal to zero so the are not roots.
let x-4 is a factor of given equation
then it satifies the equation ie (x-4) is a root
And it may be written as
[tex](x-4)(x^2+9)
