Four-hundred point twenty-nine
Step-by-step explanation:
The answer which you have chosen is <u>correct</u>.
<em><u>The equation of the function is:</u></em>
<em><u>Solution:</u></em>
<em><u>The vertex form of equation is given as:</u></em>
Where, (h, k) is the vertex
Given that, The graph of a quadratic function has the vertex (4, 2)
(h, k) = (4, 2)
Substitute in eqn
And passes through the point (5,5)
Substitute (x, y) = (5, 5) in above
Substitute a = 3 and (h, k) = (4, 2) in vertex form
Thus the equation of function is found
Surface area is the total area of the 2d cutout you have shown, because if folded it would be the area of the surface. Remember that each side of a rectangle has the same value on the other side. For example, where "2ft" is placed on the far left of the diagram, the side just to the right of it would also be 2ft. Once you have these values all written down, you can evaluate the area of each individual box within the entire diagram by multiplying the width by height. Once you have the area of each individual box, add all the area values together to find the surface area.
