What is the value of log5 125

[tex]log_5125=3[/tex]

Step-by-step explanation:

Given : [tex]log_5125[/tex]

We have to find the value of [tex]log_5125[/tex]

Consider the given expression [tex]log_5125[/tex]

Rewrite 125 in power- base form, [tex]125=5^3[/tex]

[tex]\mathrm{Apply\:log\:rule}:\quad \log _a\left(x^b\right)=b\cdot \log _a\left(x\right)[/tex]

[tex]\log _5\left(5^3\right)=3\log _5\left(5\right)[/tex]

[tex]=3\log _5\left(5\right)[/tex]

[tex]\mathrm{Apply\:log\:rule}:\quad \log _a\left(a\right)=1[/tex]

[tex]\log _5\left(5\right)=1[/tex]

[tex]3\log _5\left(5\right)=3[/tex]

Thus, [tex]log_5125=3[/tex]

The value of log_5 125 is 3.

We have,

To find the value of log base 5 of 125, we need to determine the exponent to which we need to raise 5 to obtain 125.

In other words,

What power do we need to raise 5 to in order to get 125.

So,

By evaluating 5³ (5 raised to the power of 3), we find that 5³ = 125.

So, log base 5 of 125 is equal to 3, as log base 5 of 125 = 3.

So,

log base 5 of 125 equals 3 because 5 raised to the power of 3 gives us 125.

Thus,

The value of log_5 125 is 3.

A sports club plans to have its lawn mowed. The cost of mowing x square feet of lawn is given by the function f(x) = 0.04x + 3.5, where f(x) represents the cost in dollars. The total area that needs to be mowed is given by the function g(x) = 12x.

Which function best describes C(x), the total cost of mowing the lawn of the sports club?

A) C(x) = 0.48x + 3.5x
B) C(x) = 0.48x2 + 3.5
C) C(x) = 0.48x2 + 42x
D) C(x) = 0.48x2 + 42

Answers

To do this, you would substitute every instance of x in the equation f(x) with the value of the g(x) equation. So, it would be C(x)=0.04(12x)+3.5. First, multiply 0.04 by 12x, which would be 0.48x. Now, your equation is C(x)=0.48x2+3.5. This is answer choice B. Hope this helps!

g(0) = 3^0 + 1 = 2

g(1) = 3^1 + 1 = 4

As of this writing, the powerball lottery is run in 42 states. winning the jackpot requires that you select the correct five numbers between 1 and 59 and, in a separate drawing, you must also select the correct single number between 1 and 39. find the probability of winning the jackpot. 34.

Answers

Final answer:

The probability of winning the Powerball jackpot is 1 in 292,201,338.

Explanation:

To find the probability of winning the Powerball jackpot, we need to calculate the probability of selecting the correct five numbers between 1 and 59 and the correct single number between 1 and 39.

The probability for each part is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.

For the five numbers, there are 59 possible choices and we need to select 5, so the probability is 1/59 × 1/58 × 1/57 × 1/56 × 1/55.

For the single number, there are 39 possible choices, so the probability is 1/39.

To find the overall probability, we multiply the probabilities of both parts together: (1/59 × 1/58 × 1/57 × 1/56 × 1/55) × (1/39) = 1/292,201,338.

Triangle ABC and triangle DEC are A.Similar B. Nonsimilar

Answers

The answer is A. Similar

Answer:

(A) Similar triangles

Step-by-step explanation:

It is given that AB is parallel to DE, therefore ∠CAB=∠DEC=65°(Alternate angles),

Then from ΔACB and ΔDCE, we have

∠CAB=∠DEC=65°(Alternate angles)

and ∠ACB=∠DCE=50°(Vertically opposite angles)

Thus, by AA similarity, ΔACB is similar to ΔDCE.

Answer:

The set will have a direct variation if each pair is added or subtracted by a common number in each component. You also can see it graphically, if the points form a straight growing line then the set is a direct variation. Then,

In the first set we have

(0,0), (0+2,0+4), (0+2+3, 0+4+11). The behavior is not uniform, then it is not a direct variation.

Second set: (-1, -2); (0,0); (1, 2)

(-1,-2)(-1+1,-2+2), (-1+1+1, -2+2+2). The behavior is uniform and it is increasing, then it is a direct variaton.

Third set:

(-2, 4), (-2+1,4-2), (-2+1+4, 4-2+4). The behavior is not uniform, then it is not a direct variation.

Fourth set:

(0,5), (0+1, 5+1), (0+1+1, 5+1+1). The behavior is uniform and it is increasing, then it is a direct variaton.

Suppose that a person with a push mower can mow a large lawn in 2 hours, whereas the lawn can be mowed with a riding lawn mower in 1 hours. working together, how long will it take to mow the lawn

Answers

Working together, the job takes x hours to do.

If a lawn can be mowed with a push mower is 2 hours, then in 1 hour, you do 1/2 of the job.

If the same lawn can be mowed with a riding mower in 1 hour, then in 1 hour you do 1 job.

If the same lawn can be mowed by the two mowers together in x hours, then in 1 hour you get 1/x done.

1/2 + 1 = 1/x

3/2 = 1/x

x = 2/3

They take 2/3 of an hour. 2/3 * 60 min = 40 minutes.

2/3 hours take to mow the lawn.

Find the first partial derivatives of the function. f(x, y) = ax + by/ cx + dy

Answers

Final answer:

The partial derivatives of the given function f(x, y) = ax + by / cx + dy with respect to x and y have been calculated, showing how the function changes with each variable while holding the other constant.

Explanation:

For the function f(x, y) = ax + by / cx + dy, the first partial derivatives with respect to x and y are:

∂f/∂x = a(cy - by') / (cx + dy)²∂f/∂y = (ax - ay) / (cx + dy)²

These partial derivatives measure the rate of change of the function f(x, y) with respect to x and y while treating the other variable as constant.

Graham uses a 10 by 10 grid to model a decreasing pattern. He cuts off a section representing a percent of the current area so that the remaining area represents the next term in the pattern, rounded to nearest whole centimeter. The area after each cut is shown on the graph.
After each cut, the remaining area is___% of the previous area

Answers

Sent a picture of the solution to the problem (s).

After the first cut, the remaining area represents 70% of the previous area.

How to calculate the area

Let's assume the initial area of the 10 by 10 grid is 100 square centimeters. After the first cut, a certain percentage of the current area is removed, leaving behind the remaining area. Let's say the remaining area after the first cut is 70 square centimeters.

To calculate the percentage of the remaining area compared to the previous area, we can use the formula:

(remaining area / previous area) * 100

In this case:

(70 / 100) * 100 = 70%

So, after the first cut, the remaining area represents 70% of the previous area.

Roger can run one mile in 8 minutes. jeff can run one mile in 6 minutes. if jeff gives roger a 1 minute head start, how long will it take before jeff catches up

Answers

recall your d = rt, distance = rate * time.

now, if Roger can do 1 mile in 8 minutes, so in 1 minute, he has done then 1/8 of a mile, so his rate is 1/8 miles per minute.

if Jeff can do 1 mile in 6 minutes, he's faster, in 1 minute he has done 1/6 of a mile, so his rate is 1/6 miles per minute.

now, when Jeff catches up with Roger, the distance covered by both will be the same, say "d" miles, because, at that millisecond, Jeff will be neck and neck with Roger, and their covered distance will be the same.

now, Jeff is generous and let Roger roll on for 1 minute before him, so, by the time time Roger has covered "d" miles, he has been running for say "t" minutes.

however, since Jeff started later by 1 minute, he hasn't been running for "t" minutes, but for "t - 1" minutes.
