Answer:
Surface area is, 478 square centimeter
Step-by-step explanation:
Surface area (S)of rectangle is given by:
.....[1]
where,
l is the length
w is the width
h is the height of the rectangle respectively.
As per the statement:
A rectangular solid has sides of 7 cm, 9 cm, and 11 cm
⇒ l = 7 cm , w = 9 cm and h = 11 cm
Substitute in [1] we have;
⇒
Therefore, the surface area is, 478 square centimeter
A graph shows the solutions to be
(x, y) = (-6, 312) or (6, 312)
To solve algebraically, remove a factor of 2 from the second equation and use that expression to substitute for y in the first equation.
10x^2 -(8x^2 +24) = 48
2x^2 = 72
x = ±√(72/2) = ±6
y = 8*36 +24 = 312
(x, y) = (-6, 312) or (6, 312)

y = 8*36 +24 = 312
By graphing the given points, we will get the attached figure
which represents:
f(x) = 3 sin x
but sin x = cos (x - π/2)
∴ f(x) = 3 cos ( x - π/2 )
The correct choice is option ⇒⇒⇒ <span>f(x) = 3 cos(x − pi over 2 ) </span>
