Answer:

x = 30

Step-by-step explanation:

Using the sine ratio in the right triangle

sinx = \frac{opposite}{hypotenuse} = \frac{2.5}{5} = \frac{1}{2} , then

x = sin^{-1} (\frac{1}{2} ) = 30

Write the first five terms of the sequence described by the recursive formula f(1)=2,f(x)=f(x-1)*4
VladimirAG [237]

Answer:

2,8,32,128,512

Step-by-step explanation:

f(x)=f(x-1)*4

f(1)=2

f(2)=f(2-1)*4=f(1)*4=2*4=8

f(3)=f(3-1)*4=f(2)*4=8*4=32

f(4)=f(4-1)*4=f(3)*4=32*4=128

f(5)=f(5-1)*4=f(4)*4=128*4=512

Find a polynomial function of lowest degree with rational coefficients
xxMikexx [17]

Since -5i is a zero, then its complex conjugate +5i is also a zero of the function.

Therefore,

x + 5i, x - 5i , and x - 3 are factors of the polynomial.

Hence, the polynomial function, P(x), of the lowest degree with rational coefficients​ is given by

P(x)=(x+5i)(x-5i)(x-3)

Which implies that

\begin{gathered} P(x)=(x^2-(5i)^2)(x-3)=(x^2-25i^2)(x-3) \\ \text{ Since i}^2=-1,\text{ then we have} \\ P(x)=(x-3)((x^2+25)=x^3+25x-3x^2-75 \end{gathered}

Hence the polynomial is

P(x)=x^3-3x^2+25x-75
