Find all real and non-real roots of the function ƒ(x) = x2 + 49. Question 1 options: A) x = –7, 7 B) x = –7i, 7i C) x = –49i, 49

malfutka [58]

Given:

The function is:

$f(x)=x^2+49$

To find:

The all the real and non-real roots of the given function.

Solution:

We have,

$f(x)=x^2+49$

For roots, $f(x)=0$ ,

$x^2+49=0$

$x^2=-49$

Taking square root on both sides, we get

$x=\pm \sqrt{-49}$

$x=\pm \sqrt{-1}\sqrt{49}$

$x=\pm 7i$ $[\because \sqrt{-1}=i]$

The roots of the given function are -7i and 7i.

Therefore, the correct option is B.

Need help finding the missing angle

lys-0071 [83]

Answer:

Step-by-step explanation:

Sinθ = opp/hyp

Sinθ = 12/13

θ = ArcSin (12/13)

θ =67.38

Let x = adj

Tan (67.38) = 15/x

2.4= 15/x

x2.4= 15

x=6.25

Therefore the missing value is 6.25
