Hey there!!
We have:
... x² + y² = 25
... x² + y² = 5²
... y² = 5² - x²
and
... y² - 2x = 25
... y² - 2x = 5²
We know y² = 5² - x²
... 5²-x²-2x = 5²
... -x² - 2x = 5²-5²
... -x² - 2x = 0
... x(-x-2) = 0
... -x-2 = 0
... -x = 2
... x = -2
<em>Hence, the value of x is -2. </em>
... x² + y² = 25
... (-2)² + y² = 25
... 4 + y² = 25
... y² = 25 - 4
... y² = 21
... y = √21
<em>Hence, the value of 'y' is √21. </em>
Hope my answer helps!!
Answer:
tan (48°19'23'') => 1.1232
Step-by-step explanation:
60' minutes are present in a degree, and 60 * 60' seconds are present in a degree;
48°19'23'' = 48 + 19/60 + 23/3600
=
=
= = 48.323°
tan(48.323°) = 1.1232

Answer:
I believe it would be 4x^2-20x+26
Step-by-step explanation:
Substitute the f(x) equation in where the x is in the g(x) equation, so...
g(f(x)) = (2x-5)^2+1 = (2x-5)(2x-5)+1 = 4x^2-20x+26.
If you want, you could factor out a 2 also to get 2(2^2-10x+13)
