kramer

Answer:

26

Step-by-step explanation:

→ Utilise Pythagoras theorem

a² + b² = c²

→ Substitute in the values

10² + 24² = c²

→ Simplify

100 + 576 = c²

→ Simplify further

676 = c²

→ Square root both sides to isolate c

26 = c

Help me out! I always mark brainliest. Unless of course, it is incorrect or inadequate. Please include how you did the problem.

If 2 + 5i is a zero, then by the complex conjugate root theorem, we must have its conjugate as a zero to have a polynomial containing real coefficients. Therefore, the zeros are -3, 2 + 5i, and 2 - 5i. We have three zeros so this is a degree 3 polynomial (n = 3).
f(x) has the equation
                        f(x) = (x+3)(x - (2 + 5i))(x - (2 - 5i))
If we expand this polynomial out, we get the simplest standard form
                        f(x) = x^3-x^2+17x+87
Therefore the answer to this question is f(x) = x^3-x^2+17x+87

A sequence is defined recursively by the formula f(n+1)=-2f(n). The first term of the sequence is -1.5. Whis is the next term in
podryga [215]
We are told that f(1) = -1.5, and that f(n+1) = -2f(n).
                                                 Then: f(2) = -2f(1) = -2(-1.5) = +3 (answer)

The resolvent is:
 x = (- b +/- root (b2 - 4ac)) / 2a
 To apply it we must have a polynomial of the form:
 ax2 + bx + c = 0
 Where,
 One side of the equation is zero.
 The polynomial must be only grade 2.
 The coefficient a must be different from zero.
 Answer:
 
options: B, C, D are correct
