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.

Final answer:

By rearranging the formula for the volume of a box to solve for width and substituting the given values, the width of the box is calculated to be 5 inches.

Explanation:

The student asks what the width of the box is, given that the volume of the box is 400 cubic inches (in³), the height is 10 inches (in), and the length is 8 inches (in). The formula to find the volume of a rectangular box is V = l × w × h, where V is the volume, l is the length, w is the width, and h is the height. Since we already have the volume, length, and height, we can rearrange the formula to solve for the width w as follows: w = V / (l × h). Substituting the given values, we get w = 400 in³ / (8 in × 10 in), which simplifies to w = 400 in³ / 80 in². After dividing 400 by 80, the result is w = 5 in. Therefore, the width of the box is 5 inches.

Answer:

b=2

Step-by-step explanation:

Changing the y-intercept would move the graph down or up.

So we have the equation [tex]y=\frac{-2}{3}x+5[/tex].

We want to move the graph down 3 units.  We want the y-intercept to be 3 units lower than what is was.  Since 5-3 is 2, then the new y-intercept is 2.

The equation would  then be [tex]y=\frac{-2}{3}x+2[/tex].

So b=2.

Answer:

AB = 2[tex]\sqrt{2}[/tex]

Step-by-step explanation:

Calculate the length using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = A(- 3, - 4) and (x₂, y₂ ) = B(- 1, - 6)

AB = [tex]\sqrt{(-1+3)^2+(-6+4)^2}[/tex]

     = [tex]\sqrt{2^2+(-2)^2}[/tex]

     = [tex]\sqrt{4+4}[/tex]

     = [tex]\sqrt{8}[/tex] = 2[tex]\sqrt{2}[/tex] ≈ 2.83 ( to 2 dec. places )

Answer:

Step-by-step explanation:

AB= √((-6+4)²+(-1+3)²)² = √(4+4)= √8 =2√2

w= x + y/z

w-x = y/z

z= y/(w-x)

y = (w-x)z

Fractions are division problems, ex 1/2 is the same as one divided by 2, so if you multiply the denominator you solve for the numerator, and to solve for the denominator just substitute what's on the other side

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).

Step-by-step explanation:

A. Given the equation

[tex]3+9=12[/tex]

Using the subtraction property of equality (subtracting 5 from both sides of equation), we'll get an equivalent equation

[tex]3+9-5=12-5[/tex]

B. Given the equation

[tex]x-4=7[/tex]

Using the addtion property of equality (adding 4 to both sides of equation), we'll get an equivalent equation

[tex]x-4+4=7+4[/tex]

C. Given the equation

[tex]2(6)=12[/tex]

Using the division property of equality (dividing  both sides of equation by 2), we'll get an equivalent equation

[tex]\dfrac{2(6)}{2}=\dfrac{12}{2}[/tex]

D. Given the equation

[tex]\dfrac{x}{2}=5[/tex]

Using the multiplication property of equality (multiplying  both sides of equation by 2), we'll get an equivalent equation

[tex]2\cdot \dfrac{x}{2}=2\cdot 5[/tex]

The operation displayed in the equation change from '3 + 9 = 12' to '3 + 9 - 5 = 12 - 5' is subtraction. The number 5 is subtracted from both sides of the original equation, altering the values while keeping the equation fundamentally equivalent and balanced.

The operation that occurred between the two equations, 3 + 9 = 12 and 3 + 9 - 5 = 12 - 5, is called subtraction. This operation is depicted by the inclusion of the -5 in both sides of the second equation. Essentially, the number 5 is being subtracted from the results of the first equation, resulting in an altered but comparable equation.

Think of it as taking the entire set of operations in the first equation, and applying an additional step to it - the step of subtracting 5, denoted in the equation as '- 5'. This step is applied to both sides of the equation to maintain its balance, keeping it equivalent to the initial equation, albeit with different values.

Continuing from our first equation, the left-hand side which was '3 + 9' (equals to 12) would become '3 + 9 - 5' (equals to 7), and the right-hand side which was '12', becomes '12 - 5' (also equals to 7). The fundamental rule being employed here is that the same operation should be performed on both sides of an equation to keep it balanced. Adjusting only one side would result in a different, non-equivalent equation.

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)

Your Question: How to calculate ratio.

The Answer/Explanation: To find an equal ratio, you can either multiply or divide each term in the ratio by the same number (but not zero). For example, if we divide both terms in the ratio 3:6 by the number three, then we get the equal ratio, 1:2.

To calculate the ratio, the width will be divided by the GCD and the height will be divided by the GCD. A colon will be placed between those two numbers. The result is 4:3 -- the ratio for those screen dimensions.

Remember to check study guides, lessons and notes to rely on; working hard is the way to success. Good Luck!

To calculate a ratio, you compare two quantities and express their relationship as a fraction, a colon-separated pair, or a "to" statement. You usually divide the larger number by the smaller and simplify to whole numbers to find the smallest whole-number ratio.

To calculate a ratio, you compare two quantities to each other. Ratios can be represented in a few different ways, such as fractions, with a colon, or with the word "to". For example, a ratio might be 2/3, 2:3 or "2 to 3". If you're dealing with a scenario where you are given two different molar amounts, you would follow these steps:

For example, if you're looking at a chemical equation and need to determine the mole ratio, divide all numbers by the smallest value presented. So, if the molar amounts are 5.5, 1, and 1.2, dividing each by the smallest amount (1 in this case) gives you the mole ratio of 5.5:1:1.2. Simplified, it would become 55:10:12 as a ratio of whole numbers.
