Answer:
the vertex is (1,-1)
Step-by-step explanation:
y = −3x^2 + 6x − 4
the vertex is at
h= -b/2a where ax^2 +bx+c
h= -6/2(-3)
h= -6/-6
h=1
substitute this in to find the y value
y = -3(1)^2 +6(1)-4
y = -3+6-4
y = -1
the vertex is (1,-1)
98 inches is the correct answer.
That is a rational number.
The answer is 3.5 & 355 because the decimal shifts to the left or right, you move the decimal in the answer too.
Answer:

Step-by-step explanation:
Given
z = 119 + 120 i
Let 
Squaring both sides

Comparing real and imaginary part
Re(LHS)=Re(RHS)
...........................(1)
comparing Im(LHS)=Im(RHS)
120=2pq

Substitute q in 1


Let 



we take only Positive value because 
x=149.85

thus 

thus,
