Mathematics
1 answer:
AlexFokin [52]3 years ago

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.

If the divisor is a decimal then you must multiply by a power of 10 to make it a whole number. Why is it important to multiply t
kotegsom [21]

It is important to multiply the dividend and the divisor by the same power of 10 to remove the decimal point.

<h3>Division of whole numbers</h3>

When the numerator and denominator of improper fractions are in whole number form, it makes the division a lot easier.

<u>For example</u>;

what is the simplest form of 0.1/0.2?

To obtain the simplest form of the above function, we multiple the numerator and denominator by 10.

= (0.1 x 10)/(10 x 0.2)

= 1/2

<u>Note:</u> introducing factor of 10 to both numerator and denominator has not changed the function.

Thus, it is important to multiply the dividend and the divisor by the same power of 10 to remove the decimal point.

Solve 5m − 3h = 45 for h. Show your work.
mezya [45]

5m − 3h = 45

Subtract 5m from both sides

-3h = 45 - 5m

Divide both sides by -3

h = (45 - 5m)/ -3

h = -15 + 5m/3

Molly's jump rope is 6 1/3 feet long. Gail's jump rope is 4 2/3 feet long. How much longer is Molly's jump rope?
yaroslaw [1]
If you would like to know how much longer is Molly's jump rope, you can calculate this using the following steps:

6 1/3 feet long - 4 2/3 feet long = 6 1/3 - 4 2/3 = 19/3 - 14/3 = 5/3 = 1 2/3

The correct result would be 1 2/3 feet longer.

Pls help will give brainlist
Ivenika [448]

Answer:

1. Yes

2. No

3. Yes

4. Yes

Step-by-step explanation:

#1

Yes, this is a function.

None of the x-values have more than one possible value for y. None of the x-values are repeated in this table.

#2

No, this is not a function.

For each and every value of x, there can only be one y. The x-value 13 has two possible values of y, 4 and -4. This is represented in the coordinates (13, 4) and (13, -4).

#3

Yes, this is a function.

The graph passes the vertical line test. If you were the pass a vertical line through the graph, it would only be touching the graph once, wherever the vertical line is placed.

#4

Yes, this is a function.

The equation given is a quadratic equation for an original parabola. All parabolas, when not inverse, are functions. This parabola opens down, so it will pass the vertical line test.
