Answer:
it answer is 3 because it is trigonometry
Answer:
B. X=0.02
Step-by-step explanation:
The solution to the natural log equation is found by taking antilogs.
ln(x) = -4 . . . . . . . given equation
x = e^-4 . . . . . . . take antilogs
x ≈ 0.0183156
x ≈ 0.02 . . . . rounded to 2 decimal places
_____
<em>Additional comment</em>
Essentially, we use each side of the equation as a power of e.
e^ln(x) = e^(-4)
x = e^-4 . . . . . . . simplified
Choices C and D can be eliminated by the fact that ln(x) for x < 0 is undefined. x cannot be negative.
The unit rate of 32 is 12
Answer:
(B) $15
Step-by-step explanation:
Big Video: y = 2.49x + 9.99
Main Street: y = 1.79x + 20.49
easiest way to solve would be to graph and find the point of intersection or set 2.49x + 9.99 and 1.79x + 20.49 equal to each other
2.49x + 9.99 = 1.79x + 20.49
subtract 1.79x from each side to get:
.70x + 9.99 = 20.49
subtract 9.99 from each side to get:
.70x = 10.50
divide each side by .70
x = 15
