Give the domain on which the equation is defined. In particular, describe the set of x for which the equation is defined, using
Anestetic [448]


law's of exponents

e^(x-5)*e^(3x+8) = 19
e^(x-5+3x+8) = 19
e^(4x+3) = 19

take the natural log, which is base "e" of both sides.

ln[e^(4x+3)] = ln[19]
4x +3 = ln[19]
4x = ln[19] - 3
x = (ln[19] - 3) / 4
x = -0.0139

Hello!

Here we have sin=opp/hyp so the sin of 45deg= 7/b so we have

Sqrt(2)/2 = 7/b so b= 7/sqrt(2)/2= 14/sqrt(2)= 14*sqrt(2)/2= 7*sqrt(2) so the final simplified answer for the value of b= 7*sqrt(2)

Any questions please ask. Thank you kindly.

Jack cuts four squares with side length X inches from corners by a 5" x 7" cardboard rectangle. He folds the remaining cardboard
viktelen [127]

Answer:

V = x^3-24x^2+35x

Step-by-step explanation:

Jack makes a cuboid. If the length is <em>l</em>, the width is <em>w</em> and the height is <em>h</em>, then its volume is

V = lwh

The height is determined by the side of the square cut out of each corner.

h = x

Along the length of the width, the length of two sides of the square are cut.

l = 7 - 2x

w = 5 - 2x

V = lwh = (7-2x)(5-2x)(x)

V = x(35-24x+4x^2) = x(x^2-24x+35) = x^3-24x^2+35x
