Solve for x: ln(3x)^2=16.

1 answer:

5 0

Ln(3x)^2 = 16

ln 9x^2 = 16 => e^16 = 9x^2 making squarroot on both sides

e^8 =3x divide both sides by 3

x = e^8 /3

A rectangular box is 32 cm wide and 36 cm high. If the surface area of the box is 4344 square centimeters, find the length of t

AnnZ [28]

To find the surface area, multiply length x width x height.

let "length" = l

l x 32 x 36 = 4344

Simplify

l x (32 x 36) = 4344

l x 1152 = 4344

Isolate the length. Divide 1152 from both sides

(l x 1152)/1152 = (4344)/1152

l = 4344/1152

l = 3.77 (rounded)

3.77 cm is your length.

hope this helps

Use the discriminant to determine the number and type of solutions for the following equation. 12x2 + 10x + 5 = 0

Paul [167]

Discriminant D is given by:
D=b²-4ac
Implication of discriminant is as follows:

D<0 two zeros that are complex conjugate
D=0 one real zero of multiplicity 2
D>0 two distinct real zers
D= (+ve perfet square) two distinct rational zeros
From:
12x^2+10x+5=0
plugging in the equation we get:
10²-4×12×5
=100-240
=-140
thus
D<0

Answer is:
<span>A two irrational solutions </span>

pychu [463]

Answer: The distribution of the data set is positively skewed.

<u>Explanation: </u>

In order to see whether the given data set is symmetric, positively skewed or negatively skewed, we will find the mean, median and mode of the given data set.

For symmetric distribution, $Mean = Median=Mode$
