Answer:

7 sqrt(2)

Step-by-step explanation:

We can use trig functions

sin theta = opposite side/ hypotenuse

sin 45 = 7/x

Multiply each side by x

x sin 45 = 7

Divide each side by sin 45

x = 7 / sin 45

x = 7 (sqrt(2) /2)

x = 14 / sqrt(2)

We do not leave square roots in the denominator

x = 14 / sqrt(2) * sqrt(2)/ sqrt(2)

   12 sqrt(2)/ 2

  = 7 sqrt(2)

(7 + 10i)+(4-10i)-(7-5i)
AleksAgata [21]

Answer:

4 + 5i

Step-by-step explanation:

To calculate this you have to combine the like terms until they cannot be combined any further:

7 + 10i + 4 - 10i - (7 - 5i)

11 + 0i - 7 - 5i

7 & 4 are liked terms so add them together + subtract 10i and 10i

4 + 5i  <--- Final answer

Hope this helps!

Complete the square to transform the quadratic equation into the equation form (x – p)2 = q. x2 + 14x + 34 = 5
Bezzdna [24]
<h3>Answer:</h3>

B) (x + 7)^2 = 20

<h3>Step-by-step explanation:</h3>

You can subtract 34 from the original equation to get

... x^2 +14x = -29

Now, you can add the square of half the x-coefficient, and you will have ...

... x^2 +14x +49 = -29 +49

... (x +7)^2 = 20 . . . . . . matches selection B

_____

<em>Comment on answer choice A</em>

The question asks for the form (x -p)^2 = q, but that does not mean that p must be positive. Here, p=-7 and q=20.
