Answer:
Step-by-step explanation:
hello :
f(x) =-2x²+4x+1 Completing The Square : f(x) =2(x²+2x)+1
f(x) = -2((x²-2x+1)-1)+1
f(x) = -2((x-1)²-1)+1
f(x) =2(x-1)²+1 ... verex form when the vertex is (1,1)
the axis of symmetry is x=1
Using a scale that has increments that are somewhat large, you could get an error if you reach half of the measuring unit. This is because when you arrive at a measurement greater than half of the measuring unit, you would have to round it up. Therefore, the greatest possible error when measuring to the nearest quarter of an inch is 1/8 inch. The greatest possible error when measuring to the nearest quarter of an inch is how the reader reads the measurement. Sometimes, we base our answers to what we can see and what we see may be different from others.
I think it’s yes good luck!!!
This would be 45.9
Get a calculator or try long division :-)
Answer:
-a(a+4)/(16 - a²)
Step-by-step explanation:
a/(a - 4) Multiply by (a + 4)/(a + 4)
= a(a + 4)/[(a – 4)(a + 4)] Multiply the denominatorator terms
= a(a + 4)/(a² - 16) Multiply by -1/(-1)
= -a(a+4)/(-a² + 16) Reorder terms in denominator
= -a(a+4)/(16 - a²)
