Answer:
x = 0
Step-by-step explanation:
-[(3^x - 1)(5^x - 1)] + 1 = 1
Subtract 1 form both sides
-[(3^x - 1)(5^x - 1)] = 0
Divide both sides by -1
(3^x - 1)(5^x - 1) = 0
Equate the factors to 0
3^x - 1 = 0
3^x = 1
Use ln both sides
ln(3^x) = ln(1)
xln(3) = 0
x = 0
5^x - 1 = 0
5^x = 1
Use ln both sides
ln(5^x) = ln(1)
xln(5) = 0
x = 0
The only solution is x = 0
Answer:
$50.40
Step-by-step explanation:
The garden has an area of ...
(15 ft)(12 ft) = 180 ft²
Amy wants to cover 1/4 of that with flowers, so the area devoted to flowers is ...
(1/4)(180 ft²) = 45 ft²
The cost for each square foot is $1.12, so the cost of the flowers will be ...
($1.12/ft²) × 45 ft² = $50.40 . . . . cost to cover 1/4 of the garden with flowers
