Y=4x²-7x+13
y-13=4(x²-(7/4)x)
y-13+4*(7/8)²=4(x²-2*(7/8)x+(7/8)²)
y-13+4*(7/8)²=4(x-(7/8))²
y-13+ 3.0625=4(x-0.875)²
y-9.9375=4(x-0.875)²
y=4(x-0.875)² +9.9375
Answer:
3a^6, -2a^5, +1a^4
Step-by-step explanation:
Answer:
(16) is the homogeneous mixture
<em><u>Explanation</u></em><em> </em><em>:</em>
The line DF is parallel to OB, therefore Angle x = Angle y.
( because, they for corresponding angle pair which are equal. )
And the angle made by an arc at center is always double the angle made by the same arc at its boundary, hence
