Answer:

  20.6 km

Step-by-step explanation:

Using (East, North) coordinates, the hiker's position ends up being ...

  22.2(cos(-45°), sin(-45°)) +40.1(cos(65°), sin(65°))

We're only interested in the second coordinate of this total, which is ...

  22.2sin(-45°) +40.1sin(65°) ≈ -15.698 +36.343 = 20.645 . . . km

The y-component of the hiker's position at the end of the second day is 20.6 km north of her starting location.

Kipish [7]

Answer:

f(g(x)) = x^4 + 12x^3 + 14x^2 -132x + 123

Step-by-step explanation:

Here, we simply will place g(x) into f(x)

So every x in f(x) is replaced by g(x)

Thus, we have;

(x^2 + 6x + 11)^2 + 2

= (x^2+6x-11)(x^2 + 6x -11) + 2

= x^4 + 6x^3 -11x^2 + 6x^3 + 36x^2 - 66x -11x^2 -66x + 121 + 2

= x^4 + 12x^3 + 14x^2 -132x + 123

PLS HELP ! Will give brainliest
Darina [25.2K]

Answer:

Step-by-step explanation:

The quadratic formula would be the following...

x = \frac{-b (+-)\sqrt{b^{2} - 4ac } }{2a}

where the original quadratic equation would be represented as follows

ax^{2} + bx +c = 0

Using this information and the information provided in the image we can plug in the quadratic equation values in the image to form the quadratic formula.

\frac{-(-20)±\sqrt{(-20)^{2} - 4(16)(-6) } }{2(16)}

That would be the correct order for the values.

What is the value of (7 + 2i)(3 - i)?
Harrizon [31]
There are two ways to work this out: normal variables or using "imaginary" numbers.

Normal variables:
(7+2i)(3-i)\\(7*3)+[7*(-i)]+(3*2i)+[2i*(-i)]\\21-7i+6i-2i^{2}\\\\21-i-2i^{2}

Imaginary numbers:
Using the result from earlier:
21-i-2i^{2}
Now since i = \sqrt{-1}, then the expression becomes:
21-i-2i^{2}\\21-i-2(\sqrt{-1})^{2}\\21-i+(-2)(-1)\\21-i+2\\\\23-i
