a giant pizza box in the shape of a rectangular prism measures 38m times 38m times 0.25m. what is the surface area of the box

Helga [31]

So the surface area of a box has this equation: A = 2 (wl + hl + hw)

w = width = 38
l = length = 38
h = height = 0.25

Plugging in:
A = 2 ((38*38) + (38*0.25) + (38*0.25))
= 2926 square meters

n + 1 = 4(n - 8)

n + 1 = 4n - 32

n - 4n = -32 - 1

-3n = -33 / : (-3)

n = 11

Find f if f′(x)=2x−3/x^4, x>0 and f(1)=2.

slavikrds [6]

$f'(x)=2x-\dfrac3{x^4}$
$\displaystyle\int f'(x)\,\mathrm dx=\int\left(2x-\frac3{x^4}\right)\,\mathrm dx$
$f(x)=x^2+\dfrac1{x^3}+C$

Given that $f(1)=2$ , we get

$2=1^2+\dfrac1{1^3}+C$
$2=2+C$
$\implies C=2$

so that

$f(x)=x^2+\dfrac1{x^3}$

Help me i have been trying to solve it. plzz

siniylev [52]

Because completementary angles add up to 180 degrees (angle 3 and angle 4)
and interior angles of a triangle will also add up to 180 degrees

if you compare these two facts, then angle 4 equals the 2 non adjacent interior angles
