Answer: [tex]48a^4[/tex]

Step-by-step explanation:

 In this case we know that the  legs of the given right triangle have these lenghts:

[tex]12a^4[/tex] and [tex]16a^4[/tex]

By definition, the sides of a right triangle are in the ratio [tex]3:4:5[/tex]

Since:

[tex]\frac{5}{4}=1.25[/tex]

We can multiply the lenght  [tex]16a^4[/tex] by 1.25 in order to find the lenght of the hypotenuse of the right triangle:

[tex](16a^4)(1.25)=20a^4[/tex]

Since the perimeter of a triangle is the sum of the lenghts of its sides, we can write the following expression for the perimeter of the given right triangle:

[tex]12a^4+16a^4+20a^4[/tex]

Simplifying, we get:

[tex]=48a^4[/tex]

The expression in the simplest form that represents the perimeter of the right triangle with legs 12a⁴  and 16a⁴ is 48a⁴

A right angle triangle has one of its angles as 90 degrees. The sides can be found using pythagoras theorem.

Therefore,

The perimeter of the right triangle is the sum of the whole sides. Therefore, let's find the hyotenuse.

c² = a² + b²

c² = (12a⁴)² + (16a⁴)²

c² = 144a⁸ + 256a⁸

c² = 400a⁸

c = √400a⁸

c = 20a⁴

Therefore, the perimeter is as follows:

perimeter = 12a⁴ + 16a⁴ + 20a⁴

perimeter = 48a⁴

Answer:

140°

Step-by-step explanation:

The interior angles of a regular nonagon are equal.

Equate the 2 given angles and solve for x

11x - 25 = 9x + 5 ( subtract 9x from both sides )

2x - 25 = 5 ( add 25 to both sides )

2x = 30 ( divide both sides by 2 )

x = 15

Substitute this value into one of the given angles

9x + 5 = (9 × 15) + 5 = 135 + 5 = 140

Thus the interior angle has a measure = 140°

The interior angle of a nonagon measure is 140°.

The given expressions are 9x+5 and 11x-25.

A regular nonagon is one in which all the 9 sides are of equal length and the 9 interior angles are of equal measure. On the other hand, when the sides of a nonagon are of unequal lengths and the angles are of different measures, it is called an irregular nonagon.

Now, equate the 2 given angles and solve for x.

That is, 11x - 25 = 9x + 5 ( subtract 9x from both sides )

⇒2x - 25 = 5 ( add 25 to both sides )

⇒2x = 30 ( divide both sides by 2 )

⇒x = 15

Substitute x = 15 value into one of the given angles

9x + 5 = (9 × 15) + 5 = 135 + 5 = 140

Therefore, the interior angle of a nonagon measure is 140°.

Answer:

See explanation

Step-by-step explanation:

A dog owner records the weight of her dog. She finds that from the age of 20 weeks to the age of 48 weeks, the dog’s weight can be modelled by the equation

[tex]w = 0.92t-0.15\ \ \ (20\le t\le 48)[/tex]

where

w = weight

t = number of week from 20 weeks to 48 weeks

If we want to extend this model to the dog's weight at birth, then find the dog's weigth when it was born.

At t = 0,

[tex]w=0.92\cdot 0-0.15\\ \\w=-0.15\ kg[/tex]

We get the dog's weight -0.15 kilograms at the day the dog was born. But this is impossible, because the dog's weight cannot be negative.

The model cannot predict the dog's weight at birth due to negative values and unrealistic linear growth for early development.

The equation w = 0.92t - 0.15 describes the weight of the dog as a function of time t in weeks, specifically for the age range of 20 weeks to 48 weeks. When t is set to 20 weeks, we can calculate the weight:

w = 0.92(20) - 0.15

= 18.4 - 0.15

= 18.25 kg.

However, if we try to extend this model to predict the dog's weight at birth (t = 0 weeks), we would get:

w = 0.92(0) - 0.15

= -0.15 kg.

A negative weight is nonsensical in this context, as animals cannot have negative weight. Moreover, the biological growth of a dog does not follow a linear pattern from birth to maturity. The model is designed to represent a specific growth phase after the initial rapid growth and development that occurs in the early weeks of life.

Growth models typically start with an exponential phase during early life, which cannot be accurately captured by a linear equation.

Answer:

The system has one solution: (4,1)

Step-by-step explanation:

We have the equations:

1) Y = -X + 5

2) Y = X - 3

Replace the "value" of Y of the 2nd eq into the 1st eq:

(X - 3) = -X + 5

Now let's leave X alone in one side of the iquality:

X + X = 5 + 3

2X = 8

X = 8/2

X = 4

Now, having the value of X, replace it into any of the aquations, let's use the 2nd:

Y = X - 3

Y = 4 -3

Y = 1

The ONE solution of this equations system is (4,1), which is the point in the xy plane where the two lines intersect.

The following equation has:

          Unique solution (one solution i.e. (4,1) )

The system of equation is given by:

                 y= -x + 5-----------(1)

             and   y= x - 3------------(2)

Now, on substituting the value of y from equation (1) into equation (2) we have:

[tex]-x+5=x-3[/tex]

On adding x on both the sides of the equation we have:

[tex]5=x+x-3\\\\5=2x-3[/tex]

on adding 3 on both the sides of the equation we have:

[tex]2x=5+3\\\\2x=8\\\\x=\dfrac{8}{2}\\\\x=4[/tex]

Now, on putting the value of x into equation (2) we have:

[tex]y=4-3\\\\y=1[/tex]

Hence, the solution is unique (one solution )

        Also, the point of intersection of the graph of two equations is solution to the system of equations.

Step-by-step explanation:

To find : How many times greater is the first 5 than the second 5 in 853,539?

Solution :

According to place value system,

Hundred Th.    Ten Th.   Thousand    Hundred    Tens   Ones

       8                    5                 3                5               3          9

The value of first 5 in the number 853,539 is at ten thousand place

So, The value of first 5 is 50000.

The value of second 5 in the number 853,539 is at hundred place

So, The value of second 5 is 500.

The times greater is the first 5 than the second 5 in 853,539 is

[tex]\frac{50000}{500}=100[/tex]

Therefore, 100 times greater is the first 5 than the second 5 in 853,539.

Final answer:

The first 5 in the number 853,539 is 1,000 times greater than the second 5 because it is in the ten thousands place, while the second 5 is in the tens place.

Explanation:

The question asks how many times greater is the first 5 compared to the second 5 in the number 853,539. To answer this, we compare the place values of each 5. The first 5 is in the ten thousands place while the second 5 is in the tens place.

The ten thousands place is 1,000 times greater than the tens place. Therefore, the first 5 (50,000) is 1,000 times greater than the second 5 (50).

Answer:

15x+100(3) ≥ $1500

x ≥ 80 pages

Step-by-step explanation:

Let x represent the number of  pages.

Manuel receives $15 per page = 15x

Plus $100 per month. Manuel would like to work for 3 months = 15x+100(3)

He wants to make at least $1500 during the summer

Thus the inequality we get is:

15x+100(3) ≥ $1500

Now solve the equation to find minimum number of pages:

15x+300 ≥ $1500

Combine the like terms:

15x ≥ 1500-300

15x ≥ $1200

Divide both sides by 15

15x ≥ $1200/15

x ≥  80 pages

Answer:

Step-by-step explanation:

Writing a system of equations is really just writing an equation for each part of the problem.  The parts here being the calories, and number of items.  It's not asking to solve it, so I will not unless you do want me to.

First variables, let's keep it simple.  O will be onion rings and M will be mozzarella sticks.

Now, I mentioned the two parts are the calories and number of items so we'll take it one at a time.  First calories.  

The total calories will equal 800, so we know the answer to the equation.  Now, how would we relate the variables?  if you had two of each item what would the total calories be?  it may be easy to figure out,  but for our purposes we want to think of it as multiplying the calories of each by the number of each item, or in other words 40*O+60*M, where O and M equal 2.  So for the general case we use the same thing, but we know what we want So our first equation is 40*O + 60*M = 800

The second is a bit simpler.  It just wants to know the total amount of things ordered.  So we are just adding O and M together.  So this gets us O + M = 14, since there are 14 things together.  Let me know if there's still something you don't understand though.  

The system of equations is: [tex]\( x + y = 14 \)[/tex] and [tex]\( 40x + 60y = 800 \)[/tex], where \( x \) represents the number of onion rings in the combination meal and \( y \) represents the number of mozzarella sticks in the combination meal.

Let's define:
- \( x \) as the number of onion rings in the combination meal.
- \( y \) as the number of mozzarella sticks in the combination meal.

The system of equations would be:

1. [tex]\( x + y = 14 \)[/tex] (since the combination meal has a total of 14 onion rings and mozzarella sticks altogether)
2. [tex]\( 40x + 60y = 800 \)[/tex] (since each onion ring has 40 calories and each mozzarella stick has 60 calories, and together they contain 800 calories)

Answer:

x = 5, -5

Step-by-step explanation:

Find the roots of [tex]x^{2} -25=0[/tex] by solving for x.

Add 25 to both sides

[tex]x^{2} =25[/tex]

Square root both sides

[tex]x = 5[/tex]

[tex]x=-5[/tex]

The solution to the quadratic equation x² - 25 = 0 is 5, -5 after using the identity a² - b² = (a + b)(a - b).

Any equation of the form [tex]\rm ax^2+bx+c=0[/tex]  where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.

As we know, the formula for the roots of the quadratic equation is given by:

[tex]\rm x = \dfrac{-b \pm\sqrt{b^2-4ac}}{2a}[/tex]

It is given that:

The quadratic equation:

x² - 25 = 0

As we know,

a² - b² = (a + b)(a - b)

Using the above identity:

x² - 5² = 0

(x + 5)(x -  5) = 0

x + 5 = 0  

x = -5

Or

x - 5 = 0

x = 5

We can also find the solution to the equation x² - 25 = 0 using the quadratic formula.

Thus, the solution to the quadratic equation x² - 25 = 0 is 5, -5 after using the identity a² - b² = (a + b)(a - b).

Answer:

The value of x in log x + log 3 = log 18 is 6.

Solution:

From question, given that log x + log 3 = log 18 ---- eqn 1

Let us first simplify left hand side in above equation,

We know that log m + log n = log (mn) ----- eqn 2

Adding log m and log n results in the logarithm of the product of m and n (log mn)  

By using eqn 2, log x + log 3 becomes log 3x.  

log x + log 3 = log 3x ---- eqn 3

By substituting eqn 3 in eqn 1, we get

log 3x = log 18  

Since we have log on both sides, we can cancel log and the above equation becomes,

3x = 18

[tex]x = \frac{18}{3} = 6[/tex]

Step-by-step explanation:

The vertex lies on the axis of symmetry which is situated at the midpoint of the zeros.

Find the zeros by letting f(x) = 0, that is

- (x - 3)(x + 11) = 0

Equate each factor to zero and solve for x

x - 3 = 0 ⇒ x = 3

x + 11 = 0 ⇒ x = - 11, thus

[tex]x_{vertex}[/tex] = [tex]\frac{-11+3}{2}[/tex] = [tex]\frac{-8}{2}[/tex] = - 4

Substitute x = - 4 into f(x) for y- value of the vertex

f(- 4) = - (- 4 - 3)(- 4 + 11) = - (- 7)(7) = 49
