Answer:

  no

Step-by-step explanation:

If you mean

  27^4 - 9^5·3^9 = -1161730026

it has no factors of 5, so cannot be divisible by 25.

__

If you mean ...

  (27^4 -9^5)/3^9 = ((3^3)^4 -(3^2)^5)/3^9 = 3^10(3^2 -1)/3^9 = 3(9-1) = 24

it is not divisible by 25, either.

Answer:

[tex]3^9(25)[/tex]

Step-by-step explanation:

Let's rewrite all values with a base of 3:

[tex]27^4 = (3^3)^4 = 3^{12}\\\\\\9^5 = (3^2)^5 = 3^{10}\\\\\\3^9 = 3^9[/tex]

Now, let's factor the equation:  [tex]3^{12} -3^{10} + 3^{9}[/tex]

[tex]\\3^{12} -3^{10} + 3^{9}\\\\= 3^9(3^3 - 3 + 1)\\\\= 3^9(27 - 2)\\\\= 3^9(25)[/tex]

Your answer is    [tex]3^9(25)[/tex]

Data collection is the process of gathering and measuring information on variables of interest. strawberry yoghurt makes up less than 1/3 of their sales

Data collection is the process of gathering and measuring information on variables of interest, in an established systematic fashion that enables one to answer stated research questions, test hypotheses, and evaluate outcomes.

The data collection component of research is common to all fields of study including physical and social sciences, humanities, business, etc. While methods vary by discipline, the emphasis on ensuring accurate and honest collection remains the same.

Answer:

The number of games Sydney played is 5 and the number of rides she went on is 8.

Step-by-step explanation:

Given:

Sydney is going to a carnival that has games and rides. Each game costs $1.25 and  each ride costs $2.25. Sydney spent $24.25 altogether at the carnival and the number  of rides she went on is 3 more than the number of games she played.

Now, to find the number of games Sydney played and the number of rides she went on.

Let the number of games she played be [tex]x.[/tex]

As given, the number  of rides she went on is 3 more than the number of games she played.

So, the number of rides be [tex]x+3.[/tex]

Each game costs $1.25 and  each ride costs $2.25. Sydney spent $24.25 altogether at the carnival.

According to question:

[tex]1.25x+2.25(x+3)=24.25[/tex]

[tex]1.25x+2.25x+6.75=24.25[/tex]

[tex]3.50x+6.75=24.25[/tex]

Subtracting both sides by 6.75 we get:

[tex]3.50x=17.50[/tex]

Dividing both sides by 3.50 we get:

[tex]x=5.[/tex]

Number of games = 5.

So, number of rides:

[tex]x+3\\=5+3\\=8.[/tex]

Therefore, the number of games Sydney played is 5 and the number of rides she went on is 8.

n = -36

Step-by-step explanation:

Let the number be n.

Then n/3 + 11 = -1

Solve for n/3, and then for n:

Subtract 11 from both sides, obtaining

n/3 = -12

Multiplying both sides by 3 yields:

n = -36

The required number that Mo thought of is -36.

A number is determined that Mo is thinking of a number. 11 more than 1/3 of the number is -1.

The speed in running is 10 mph and speed in biking is 16 mph

Solution:

Given that, Cruz is training to compete in a triathlon

He left his house at 6:00 and ran until 7:30

Time taken for running = 1.5 hours

Then he rode his bike until 9:45

7: 30 to 9: 45 is biking time

Time taken for biking = 2.25 hours

He covered a total distance of 51 miles

Total distance = 51 miles

Let "x" be the speed in running

His speed when biking was 1.6 times his speed when running

Speed in biking = 1.6x

Total distance = distance in running + distance in biking

The distance is given by formula:

[tex]distance = speed \times time[/tex]

Therefore,

[tex]Total\ Distance = x \times 1.5 + 1.6x \times 2.25\\\\51 = 1.5x + 3.6x\\\\5.1x = 51\\\\x = 10[/tex]

Thus speed in running is 10 miles per hour

Speed in biking = 1.6x = 1.6(10) = 16

Thus speed in running is 10 mph and speed in biking is 16 mph

The maximum number of pages for which the time to print at Jerry's Print Shop is less than at Joe's Print Shop is 14.

This question deals with comparing two linear equations [tex]t1 = 45 + 5p[/tex] for Joe's Print Shop and t2 = 30 + 6p for Jerry's Print Shop. To determine the maximum number of pages (p) where Jerry's shop is quicker than Joe's, we need to find the value of p where t2 < t1.

Setting the two equations equal to each other, we get:

[tex]45 + 5p = 30 + 6p,[/tex]

Solving this equation, we find that p = 15.

However, p=15 is when the time at both shops is the same. Since we want the number of pages for which Jerry’s is less than Joe's, we should choose the next value lower, which is p=14.

The length of side CD is 11.

To find the length of side CD, we can use the distance formula, which is as follows:

distance = √((x2 - x1)^2 + (y2 - y1)^2)

where (x1, y1) and (x2, y2) are the coordinates of the two points.

In this case, the coordinates of the two points are (-4, -5) and (-4, 6). Substituting these coordinates into the distance formula, we get:

distance = √(((-4) - (-4))^2 + ((6) - (-5))^2)

distance = √(0^2 + 11^2)

distance = √121

distance = 11

Answer:

Step-by-step explanation:

72%

Answer: 72%

Step by Step Explanation:

1. We assume, that the number 25 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 100% equals 25, so we can write it down as 100%=25.

4. We know, that x% equals 18 of the output value, so we can write it down as x%=18.

5. Now we have two simple equations:

1) 100%=25

2) x%=18

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

100%/x%=25/18

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 18 is what percent of 25

100%/x%=25/18

(100/x)*x=(25/18)*x       - we multiply both sides of the equation by x

100=1.38888888889*x       - we divide both sides of the equation by (1.38888888889) to get x

100/1.38888888889=x

72=x

x=72

now we have:

18 is 72% of 25

The range is the resulting y-values we get after substituting all the possible x-values.

For the given function : [tex]f(x) = \frac{3}{4x} -4[/tex]

See the attached figure.

The zeros of the denominator at x = 0

The domain is: (-∞,0)∪(0,∞)

The range of the function is the domain of the inverse function of f(x)

y = 3/(4x) - 4

y + 4 = 3/(4x)

4x = 3/(y+4)

[tex]x=\frac{3}{4(y+4)}[/tex]

The zeros of the inverse function:

4(y+4) = 0

y + 4 = 0

y = -4

∴ The range is (-∞,-4)∪(-4,∞)

So, the answer is {y | y > –4} ∪ {y | y < – 4}

Step-by-step explanation:

Answer:

C.

Step-by-step explanation:

Consider the numerator;

When (x - 3)(x - 4) = 0

x = 3 or x = 4.

When x > 3 and < 4 (x - 3)(x- 4)  will be negative and the denominator  (x - 5(x + 6)^2 will be negative so the function will be positive.

So 3  < x < 4 is a part of the answer.

When x > 5 the denominator will be positive  and so will be the numerator.

So x > 5 also is a solution.

When x < 3 the numerator will be positive and the denominator will be negative so the function will be negative.

The minimum value for  [tex]f(x) = 0.15(x + 1)^2 - 3[/tex] is [tex]-3[/tex].

Step-by-step explanation:

Given function is [tex]f(x) = 0.15(x + 1)^2 - 3[/tex]

We need to find the maximum value or the minimum value for the function.

Now, differentiate [tex]f(x) = 0.15(x + 1)^2 - 3[/tex]  w.r.t [tex]x[/tex].

[tex]f'(x) =\frac{d}{dx}(0.15(x + 1)^2 - 3)\\f'(x)=\frac{d}{dx}(0.15(x+1)^2-\frac{d}{dx}(3)\\[/tex]

[tex]f'(x)=2\times 0.15(x+1)\frac{d}{dx}(x+1)-0\\f'(x)=0.3(x+1)(1)\\f'(x)=0.3(x+1)[/tex]

Now, we will equate [tex]f'(x)=0[/tex] to find critical point.

[tex]0.3(x+1)=0\\x=-1[/tex]

Plug this critical point in to the function [tex]f(x) = 0.15(x + 1)^2 - 3[/tex]  we get,

[tex]f(-1) = 0.15(-1 + 1)^2 - 3\\f(-1)=-3[/tex]

Also, [tex]f''(x)=0.3[/tex] which is positive, We have minimum value.

So, the minimum value for  [tex]f(x) = 0.15(x + 1)^2 - 3[/tex] is [tex]-3[/tex].

Answer:

2102

Step-by-step explanation:

Evaluate   -x³+3x²+5x+1   when x = -12

simply substitue x = -12 into the equation

-x³+3x²+5x+1   when x = -12

= -(-1728) + 3(144) - 60 + 1

= 1728 + 432 - 60 +1

= 2102

To evaluate the polynomial -x^3 + 3x^2 + 5x + 1 for x = -12, we substitute -12 for x and simplify, resulting in a final value of 2101.

The student is asking to evaluate the polynomial -x^3 + 3x^2 + 5x + 1 when x = -12. To solve this, we substitute -12 for x in the polynomial and simplify:

Therefore, when x = -12, the polynomial evaluates to 2101.
