Answer:
9.4.
Step-by-step explanation:
9^2 = 81 and 10^2 = 100
So the value of the square root of 89 is between 9 and 10.
The gap between the squares is 100-81 = 19 and the gap between 89 and 81 is 8 so an estimate of the square root would be 9 + 8/19 of the gap between 9 and 10.
9 + 8/19 = 8.42.

Answer:
The vertex is ( -5,0)
Step-by-step explanation:
The vertex form of a parabola is
y = a( x-h) ^2 +k
where ( h,k) is the vertex
y=2(x+5)^2
y=2(x - -5)^2 +0
The vertex is ( -5,0)
Answer:
=x2y−2xy2+7y2z
Step-by-step explanation:
Simplify
Let's simplify step-by-step.
4x2y+3y2z−2xy2−3x2y+4y2z
=4x2y+3y2z+−2xy2+−3x2y+4y2z
Combine Like Terms:
=4x2y+3y2z+−2xy2+−3x2y+4y2z
=(4x2y+−3x2y)+(−2xy2)+(3y2z+4y2z)
=x2y+−2xy2+7y2z
Answer:
=x2y−2xy2+7y2z
