Mathematics
1 answer:
Anni [7]3 years ago

Answer:

0.5

Step-by-step explanation:

Circumference of a circle = 2πr.

Given, circumference = 3.14 meters.

Therefore,

2πr = Circumference of a circle

or, 2πr = 3.14.

or, 2 × 3.14r = 3.14,[Putting the value of pi (π) = 3.14].

or, 6.28r = 3.14.

or, r = 3.14/6.28.

or, r = 0.5.

Identify the error in the student solution shown below. Find the correct answer.
AlexFokin [52]

Answer:

Step-by-step explanation:

The answer is Since 0 in ln(3x) - 0 is not a logarithm, the property of logarithms cannot be used here.

The difference shown cannot be written as a quotient of logarithms.

The step ln(x2) = ln(3x) - (0) reduces to

ln(x2) = ln(3x).

The possible solutions are 0 and 3, with 0 being extraneous.

6y<18
myrzilka [38]
Until the end of the problem, pretend the "less-than" sign is an equal sign. What you wanna do is solve for y by getting it by itself. You do this by dividing both sides by 6:
y=18

Because both sides were divided by a positive number, you do NOT flip the sign and leave it as it is:
y<18
