Write ln 2x + 2x ln x -ln 3y as a single logarithm.
andreev551 [17]

Answer: option c.

Step-by-step explanation:

 To solve this problem you must keep on mind the properties of logarithms:

ln(b)-ln(a)=ln(\frac{b}{a})\\\\ln(b)+ln(a)=ln(ba)\\\\a*ln(b)=ln(b)^a

Therefore, knowing the properties, you can write the expression gven in the problem as shown below:

ln2x+2lnx-ln3y=ln2x+lnx^2-ln3y\\\\=ln(2x)(x^2)-ln3y\\\\=ln(\frac{2x^3}{3y})

Therefore, the answer is the option c.

Virginia Beach is 10 miles wide and 30 miles long. If one inch of rain falls on Virginia Beach, how many cubic feet of rain fell
Arte-miy333 [17]

1 mile = 5280 feet.

Convert the dimensions to feet:

10 miles = 5280 x 10 = 52,800 feet

30 miles = 5280 x 30 = 158,400 feet

Multiply together to get the area:

52,800 x 158,400 = 8,363,520,000 square feet.

1 inch = 1/12 of a foot.

Multiply the area by 1/12 for the volume of rain:

8,363,520,000 x 1/12 = 696,960,000 cubic feet.

The length of a rectangle field is 20 less than its width. The area of the field is 12000 ft ^2. What is the width of the field?
Naddik [55]
L = w - 20

12000 = w × ( w - 20 )
12000 = w^2 - 20w
w^2 - 20w - 12000 = 0
( w - 10 ) ( w - 10 ) = 0

width = 10
