Select the quadratic equation that has roots x=8 and x=-5
stellarik [79]

Step-by-step explanation:

Since, x=8 and x=-5 are the roots.

Therefore, (x - 8) & (x - 5) will be factors.

Hence, required quadratic equation can be given as:

(x - 8)(x - 5) =0 \\  \\  \therefore  {x}^{2}  + ( - 8 - 5) x+ ( - 8) \times ( - 5) = 0 \\  \\ \therefore  {x}^{2}  + ( - 13) x+ 40= 0  \\  \\ \huge \red{ \boxed{ \therefore  {x}^{2}  - 13x+ 40= 0 }} \\ is \: the \: required \: quadratic \: equation.

Find x such that 3^x = 27 mod 32 (b)
gregori [183]

Answer:

The value of x is 11.

Step-by-step explanation:

Consider the provided information.

It is given that 3^x = 27 mod\ 32

We know that:

3^4=81

Now if we divide the number 81 with 32 it will gives us remainder 17.

This can be written as:

3^4\equiv 17(mod\ 32)

Now use the property: a^n\equiv b^n(mod\ m)

(3^4)^2\equiv 17^2(mod\ 32)

17²=289, if we divide 289 with 32 it will gives us remainder 1, thus.

3^8\equiv 1(mod\ 32)

Multiply both the sides by 3³.

3^8\times 3^3\equiv 3^3(mod\ 32)

3^{11}\equiv 27(mod\ 32)

Hence, the value of x is 11.
