Hello!</h3>
In order to find the vertex of a parabola, we use the following formula:
Remember, a parabola looks like so:
Now we know what a and b stand for.
In this case, b is -4, and a is -1:
Simplify:
Divide:

Volume of Rectangular prism= Area of base×Height of Prism
=22.9×7.5×4.6
=790.05 m³
to the nearest cubic meter:
=790 m³
1/2(4x-2)-2/3(6x+9)
(2x-1)-(4x+6)
2x-1-4x+62x-4x-1+6
-2x+5=2.5
So I believe that it is greater than 4
You can do the opposite, as in multiplying.
9.2× 5.3 = 48.76
48.76 = D
The radius of the sector of the circle with the given area is: B. 3.
<h3>What is the Area of a Sector?</h3>
Area of sector of a circle = ∅/360 × πr².
Given the following:
Area of sector = 9/8 π cm².
∅ = 45 degrees
Plug in the values into the formula
9/8π = 45/360 × πr²
1.125 = 0.125 × r²
1.125/0.125 = r²
9 = r²
r = 3 cm
