Answer:
x1=(-4+5i)/2
x2=(-4-5i)/2
Step-by-step explanation:
4x^2 +16x+49=8
4x^2+16x+49-8=0
4x^2 +16x+41=0
a=4, b=16, c=41
x1=(-b+sqrt(b^2-4ac))/2a
x2=(-b-sqrt(b^2-4ac))/2a
x1=(-16+sqrt(16^2-4*4*41))/2*4
x1=(-16+sqrt(256-656))/8
x1=(-16+sqrt(-400))/8
x1=(-16+20i)/8
x1=(-4+5i)/2
x2=(-4-5i)/2
Answer:
option 2
Step-by-step explanation:
In this number line, each interval equals 1/4.
P represents 1 1/4
So, opposite of number P is ( )
The square root of 400 is 20. It's a real number, 20 x 20 = 400
√400 = 20
I hope this helps!
59.4, because rounding to the nearest tenth means leaving one decimal place.
Answer:
Step-by-step explanation:
This might have been helpful to Newton as it allowed him to focus more clearly on his ideas. Newton was incredibly talented and ahead of his time in his field, which being in isolation helped him focus and develop on his ideas. This is not the case for the majority, most scientists tend to focus on a single aspect of a problem, usually the aspect that they have the most experience in. This can lead to them being blinded and not being able to see the possible solution. That is why working with others that are able to view the problem from a different perspective can help greatly.
