If a 45º-45º-90º triangle has a hypotenuse of length 9, find the leg length.

iVinArrow [24]

Answer:

Step-by-step explanation:

x²+x²=9²

2x²=81

x²=81/2=(81×2)/4

x=9√2/2≈4.5√2≈6.36

x²+x²=11²

2x²=11²

x²=11²/2

x=11/√2=11√2/2≈7.78

Find f'(x) if f(x) = (2/(x^1/3)) + 3 cos x + x^pi

galben [10]

The derivative of $f$ is

$f'(x)=\left(2x^{-1/3}+3\cos x+x^\pi\right)'$

$f'(x)=\left(2x^{-1/3}\right)'+(3\cos x)'+\left(x^\pi\right)'$

By the power rule,

$f'(x)=-\dfrac23x^{-4/3}+(3\cos x)'+\pi x^{\pi-1}$

The derivative of $\cos x$ is $-\sin x$ :

$f'(x)=-\dfrac23x^{-4/3}-3\sin x+\pi x^{\pi-1}$

A gift bag shaped like a rectangular prism has a volume of 1152 cubic inches. The dimensions of the gift bag in terms of its wid

exis [7]

Answer:

Given below.

Step-by-step explanation:

Gift bag is shaped in a rectangular prism.

<em> rectangular volume: length * width * height</em>

( 2w + 4 ) ( w ) ( 18 - w ) = 1152

( 2w² + 4w ) ( 18 - w ) = 1152

-2w³+32w² +72w = 1152

-2w³+32w² +72w - 1152 = 0

$-2\left(w-16\right)\left(w+6\right)\left(w-6\right)=0$

w = 16 , -6 , 6

w = 16 , 6

length = ( 2w + 4 ) = 36 inch , 16 inch

width = ( w ) = 16 inch , 6 inch

height = ( 18 - w ) = 2 inch , 12 inch
