Answer:
4*sqrt(2)
Step-by-step explanation:
lets use Pythagorean Theorem
a^2+b^2=c^2
4^2+4^2=c^2
16+16=c^2
32=c^2
|c|=sqrt(32)
|c|=sqrt(4*4*2)
|c|=4*sqrt(2)
c= ±4*sqrt(2)
since distance can't be negative, the answer is +4*sqrt(2) or just 4*sqrt(2)
No solution for this question
Answer:
Step-by-step explanation:
1) In this question we've been given "a", the leading coefficient. and two roots:
2) There's a theorem, called the Irrational Theorem Root that states:
If one root is in this form 
then its conjugate 
. is also a root of this polynomial.
Therefore
3) So, applying this Theorem we can rewrite the equation, by factoring. Remembering that x is the root. Since the question wants it in this expanded form then:
Answer:
6
Step-by-step explanation:
4 * x + 12= 36
-12 -12
4x = 24
x= 6
Step-by-step explanation:
% calculations are totally easy, if you remember to always find and the use 1%.
100% = $2.85
1% = 100%/100 = 2.85/100 = 0.0285
the price difference was
2.91 - 2.85 = $0.06
how many % are these $0.06 compared to yesterday's price ?
that is how many times 1% can fit into this number.
0.06 / 0.0285 = 2.105263158...%
so, rounded this is 2.1%
