<u>Given</u><u>:</u>
- Area of rectangular prism ( cuboid ) = 448 cm²
<u>To</u><u> </u><u>find</u><u> </u><u>out</u><u>:</u>
Find the height, h ?
<u>Formula </u><u>used </u><u>:</u>
Area of rectangular prism ( cuboid ) = 2 ( lb + bh + hl )
<u>Solution</u><u>:</u>
We know that that,
Area of rectangular prism ( cuboid ) = 2 ( lb + bh + hl )
=> 448 = 2 ( 14 × 6 + 6 × h + h × 14 )
=> 448 = 2 ( 84 + 6h + 14h )
=> 448 = 2 ( 84 + 20h )
=> 448 = 168 + 40h
=> 40h = 448 - 168
=> 40h = 280
=> h = 280/40
=> h = 7 cm
Answer:
f(x) = 3x²
Step-by-step explanation:
<u>Quadratic Function :- </u>
The function whose highest degree of variable is 2 is called a quadratic function .
- On looking at the given options , we see that the third options satisfies the definition of Quadratic Function . That is,
f(x) = 3x²
<h3>
<u>Hence</u><u> the</u><u> </u><u>third </u><u>option </u><u>is</u><u> </u><u>correct</u><u> </u><u>.</u></h3>
