The equation for this parabola is y = -2x² - 2x + 4.

An equation in which is  the highest power of to the  variables 1 is knowns as the  linear equation. Mathematically: it is an  algebraic equations that can be also  written in the form of  ax + b = 0 or ax + by + c = 0, where a, b and c are definitely real numbers and x and y are variables with the highest power one.

In order to solve this problem, we must set up a proportion. Proportions are an equation that states that two ratios are equal. In this case, we are looking for the number of cats (c) in the animal shelter.
No, there does not have to be a parabola that will pass through any three points. For a parabola to pass through three points, the three points must be collinear, meaning that they must lie on the same straight line. If the three points are not collinear, then there is no parabola that will pass through them.

The shaded area contains area A and two of area B. The expression for that area can be written ...

  Area of trapezoid = A + 2×B

The overall rectangle has an area of D. The areas labeled C can be subtracted from that to leave the shaded area. The expression for that is ...

  Area of trapezoid = D - 2×C

This criterion can be defined based on the desired level of accuracy or when the change in the estimated parameters falls below a certain threshold.

When implementing a program for a nonlinear problem using the least square adjustment technique, it is essential to determine a termination condition. This condition dictates when the program should stop iterating and provide the final estimated parameters. A common approach is to set a convergence criterion, which measures the change in the estimated parameters between iterations.

One possible criterion is to check if the change in the estimated parameters falls below a predetermined threshold. This implies that the adjustment process has reached a point where further iterations yield minimal improvements. The threshold value can be defined based on the desired level of accuracy or the specific requirements of the problem at hand.

Alternatively, convergence can also be determined based on the objective function. If the objective function decreases below a certain tolerance or stabilizes within a defined range, it can indicate that the solution has converged.

Considering the chosen termination condition is crucial to ensure that the program terminates effectively and efficiently, providing reliable results for the nonlinear problem.

Answer:

$16.50

Step-by-step explanation:

$27.50/5=5.5

5.5*3=16.5

Answer:

What we can do is calculating what one bag cost. If we know that 5 cost 27.50 dollars, to know how much does one cost we only divide:

27.50/5 = 5.50 dollars

Now, we know how much does one bag cost, so we multiply it by three:

5.50 * 3 = 16.50

Now, we know 3 bags cost 16.5 dollars

Answer:

the angles of the triangle are 45 degrees, 60 degrees, and 75 degrees, and they are in the ratio of 3 : 4 : 5.

Step-by-step explanation:

Let's denote the angles of the triangle as 3x, 4x, and 5x, where x is a constant.

Since the sum of the angles of a triangle is 180 degrees, we can write the following equation:

3x + 4x + 5x = 180

Simplifying this equation, we get:

12x = 180

Dividing both sides by 12, we get:

x = 15

Therefore, the angles of the triangle are:

3x = 3(15) = 45 degrees

4x = 4(15) = 60 degrees

5x = 5(15) = 75 degrees

So the angles of the triangle are 45 degrees, 60 degrees, and 75 degrees, and they are in the ratio of 3 : 4 : 5.

F(3,3)

Step-by-step explanation:

The coordinate of F is (3, 3).

Three vertices of parallelogram DEFG are D(0, 2), E(-1, 5), and G (4, 0).

Diagonals of a parallelogram bisect each other, meaning they divide each other into equal parts.

The formula is used to find the midpoints are as follows;

\(\rm \dfrac{x_1+x_2}{2} , \ \dfrac{y_1+y_2}{2}\)

Let (x, y) = coordinates of vertex F.

DF and EG are diagonals of parallelogram DEFG, therefore:

The midpoint of DF = midpoint of EG

Then,

The midpoint of D(0, 2) and F(x, y) is;

\(\rm \dfrac{x_1+x_2}{2} , \ \dfrac{y_1+y_2}{2}\\\\\dfrac{0+x}{2}, \ \dfrac{2+y}{2}\)

The midpoint of E(-1, 5) and G(4, 0) is;

\(\rm \dfrac{x_1+x_2}{2} , \ \dfrac{y_1+y_2}{2}\\\\\rm \dfrac{-1+4}{2} , \ \dfrac{5+0}{2}\\\\\dfrac{3}{2}, \dfrac{5}{2}\)

Comparing the equation;

\(\rm \dfrac{0+x}{2} = \dfrac{3}{2}\\\\\dfrac{x}{2} = \dfrac{3}{2}\\\\x=3\)

\(\rm \dfrac{2+y}{2} =\dfrac{5}{2}\\\\2+y =5\\\\y = 5-2\\\\y =3\)

Hence, the coordinate of F is (3, 3).

The length of one side of the square park is approximately 26.87 meters.

To find the length of one side of the square park, we can use the Pythagorean theorem. In a square, the diagonal walkway forms a right-angled triangle with two equal sides (the sides of the square).

Let the length of one side be x meters. According to the Pythagorean theorem, the sum of the squares of the two shorter sides (x^2 and x^2) equals the square of the longest side (38^2).

x^2 + x^2 = 38^2

Combine the x^2 terms:

2x^2 = 38^2

Divide by 2:

x^2 = (38^2) / 2

Now, take the square root of both sides to find the length of one side:

x = √((38^2) / 2)

x ≈ 26.87 meters

Answer:

Da answer issss...7.4 x 10^4..I tink

The quotient of 5.846 x 10^7 and 7.9 x 10^2 expressed in scientific notation is 7.4*10⁴.

Given numbers are:

\(5.846*10^7\)

\(7.9*10^2\)

Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10.

For example, 850,000,000 can be written in scientific notation as 8.5 ✕ 10^8.

So, \(\frac{5.846*10^7}{7.9*10^2}\)

\(=\frac{5.846}{7.9} *\frac{10^7}{10^2}\)

\(=0.74*\frac{10^7}{10^2}\)

We know that \(\frac{a^m}{a^n} =a^{m-n}\)

So, \(0.74*\frac{10^7}{10^2} = 0.74*10^5\)

\(=7.4*10^4\)

Hence, the quotient of 5.846 x 10^7 and 7.9 x 10^2 expressed in scientific notation is 7.4*10⁴.

Answer:

The measure of angle B must be 81° because angles A and B are interior supplementary angles

Step-by-step explanation:

Let us revise the properties of a parallelogram

In any parallelogram:

Let us solve our question

In parallelogram ABCD

∵ AD and BC are opposite sides

∴ AD // BC

∵ ∠A and ∠B are adjacent angles

→ That means ∠A and ∠B are interior supplementary angles

∴ ∠A and ∠B are supplementary angles

∵ The sum of the measures of the supplementary angles is 180°

∴ m∠A + m∠B = 180°

∵ m∠A = 99°

∴ 99° + m∠B = 180°

→ Subtract 99° from both sides

∴ 99° - 99° + m∠B = 180° - 99°

∴ m∠B = 81°

The measure of angle B must be 81° because angles A and B are interior supplementary angles

-14.29%

Step-by-step explanation:

For #2:

Original price is $2.00, that price decreased by $0.25 is $1.75. First figure out what $0.25 out of $2.00 is as a percent:

0.25/2.00 = 0.125 = 12.5%

Then, since the price DECREASED by $0.25, the percent would be negative.

For #4:

Original price is $3.50, that price decreased by $0.50 is $3.00. Like #2, you need to figure out what $0.50 out of $3.50 is as a percent:

Answer:

\(x=2\)

Step-by-step explanation:

So we have the equation:

\(5^x+5^{x+1}=150\)

First, separate the second term:

\(5^x+(5\cdot5^x)=150\)

Let u equal 5ˣ. So:

\(u+5u=150\)

Combine like terms:

\(6u=150\)

Divide both sides by 6:

\(u=25\)

Substitute back u:

\(5^x=25\)

Take the base 5 logarithm of both sides:

\(\log_5(5^x)=\log_5(25)\)

The left cancels:

\(x=\log_5(25)\)

Evaluate the right:

\(x=2\)

So, our answer is 2.

The distribution function of M, FM(-), is given by FM(x) = x, 0 ≤ x ≤ 1.

The probability density function of M is\(fM(x) = n * x^(^n^-^1^)\), 0 ≤ x ≤ 1.

In order to understand the distribution function of M, we need to consider the probability that M is less than or equal to a given value x. Since each Xi is uniformly distributed over (0,1), the probability that Xi is less than or equal to x is x.

For M to be less than or equal to x, all of the random variables Xi must be less than or equal to x. Since these variables are independent, their joint probability is the product of their individual probabilities. Therefore, the probability that M is less than or equal to x can be expressed as the product of n x's: P(M ≤ x) = x * x * ... * x = \(x^n\).

The distribution function FM(x) is defined as the probability that M is less than or equal to x. Therefore, FM(x) = P(M ≤ x) = \(x^n\).

To find the probability density function (PDF) of M, we differentiate the distribution function FM(x) with respect to x. Taking the derivative of \(x^n\)with respect to x gives us \(n * x^(^n^-^1^)\). Since the range of M is (0,1), the PDF is defined only within this range.

The distribution function of M is FM(x) = x, 0 ≤ x ≤ 1, and the probability density function of M is \(fM(x) = n * x^(^n^-^1^)\), 0 ≤ x ≤ 1.
