Hi there!

To find the slope of a line when we have 2 points, we use this formula:

m=\(\frac{y2-y1}{x2-x1}\)

where m is the slope.

\(\frac{7-7}{7-3}\)

Notice that if we subtract the y-coordinates, we get 0. We know that 0 divided by any number is 0.

So the slope of this line is 0.

So if the y-coordinates are the same, then the slope is 0.

Now, let's find the slope of the next line.

\(\frac{-5-3}{-4-(-4)} \\\frac{-8}{-4+4} \\\frac{8}{0}\)

Do you see what I see?

We cannot divide by 0 because division by 0 is undefined. So the slope of this line is undefined.

Remember:

Hope this helps you!

The graph of the exponential function

The rule of an exponential function is that

The domain is the set of all real numbers

This means that the input value can take all real values

The solution to the operation in this problem is given as follows:

9.

First we solve the integrals inside the floor operation.

At the numerator, the integral is given as follows:

\(\int_0^1 (\sum_{n = 3}^{n = 5} 5n \sqrt{25}) dx\)

Applying the square root of 25 = 5, we have that:

\(\int_0^1 (\sum_{n = 3}^{n = 5} 25n) dx\)

The sum can be applied as follows:

\(\sum_{n = 3}^{n = 5} 25n = 25(3) + 25(4) + 25(5) = 300\)

Thus the integral is given as follows:

\(\int_0^1 300 dx\)

N = 300x, from x = 0 to x = 1.

Applying the Fundamental Theorem of Calculus, the numerator for the floor operation is given as follows:

N = 300(1) - 300(0) = 300.

The sum in the denominator is given as follows:

\(\sum_{n = 2}^{n = 5} 2 + 6 = \sum_{n = 2}^{n = 5} 8 = 4 \times 8 = 32\)

Thus the integral is given as follows:

\(\int_0^1 32 dx\)

D = 32x, from x = 0 to x = 1.

Meaning that the denominator has a value of 32.

Then the whole operation can be resumed as follows:

floor(300/32).

The quotient of 300 and 32 is given as follows:

300/32 = 9.375.

Then the floor operation gives the highest integer that is less than the decimal number, as follows:

floor(9.375) = 9.

To simplify the expression (2x-3)(5x^2-2x+7), we can use the distributive property.

First, multiply 2x by each term inside the second parentheses:

2x * 5x^2 = 10x^3

2x * -2x = -4x^2

2x * 7 = 14x

Next, multiply -3 by each term inside the second parentheses:

-3 * 5x^2 = -15x^2

-3 * -2x = 6x

-3 * 7 = -21

Combine all the resulting terms:

10x^3 - 4x^2 + 14x - 15x^2 + 6x - 21

Now, combine like terms:

10x^3 - 19x^2 + 20x - 21

So, the simplified expression is 10x^3 - 19x^2 + 20x - 21.

Answer:

\( \hat p=\frac{0.56137+0.60529}{2}= 0.58333\)

The critical value for 95% of confidence is \(z_{\alpha/2}=1.96\)

And since we know the total and the proportion is defined as:

\( \hat p=\frac{X}{n}\)

If we solve for X (number of people who say yes) we got:

\( X= 0.58333* 504= 293.998 \approx 294\)

And the best answer would be:

294

Step-by-step explanation:

We know that the confidence interval for the proportion is given by:

\( \hat p \pm z_{\alpha/2} \sqrt{\frac{\hat p(1-\hat p)}{n}}\)

The margin of error for the proportion interval is given by this formula:  

\( ME=z_{\alpha/2}\sqrt{\frac{\hat p (1-\hat p)}{n}}\)    (a)  

The margin of error can be calculated with this formula:

\( ME=\frac{0.60529- 0.56137}{2}= 0.02196\)

And the estimation for the true proportion is:

\( \hat p=\frac{0.56137+0.60529}{2}= 0.58333\)

The critical value for 95% of confidence is \(z_{\alpha/2}=1.96\)

And since we know the total and the proportion is defined as:

\( \hat p=\frac{X}{n}\)

If we solve for X (number of people who say yes) we got:

Answer:

Step-by-step explanation:

The given quadrilaterals, 1 and 2,  are parallelograms because the pair of opposite sides are parallel and the other pairs are congruent.

3. According to Theorem 7.9, quadrilateral ABCD is a parallelogram.

4. According to Theorem 7.12, quadrilateral PQRS is a parallelogram.

3. Quadrilateral ABCD with vertices A(0,0), B(7,1), C(5,6), D(-2,5), and Theorem 7.9:

Theorem 7.9 states that if the opposite sides of a quadrilateral are congruent, then the quadrilateral is a parallelogram.

Using the distance formula, we can calculate the lengths of the sides of quadrilateral ABCD:

AB = √((7 - 0)² + (1 - 0)²) = √50

BC = √((5 - 7)² + (6 - 1)²) = √29

CD = √((-2 - 5)² + (5 - 6)²) =√50

DA = √((0 - (-2))² + (0 - 5)²) = √29

We can see that AB = CD and BC = DA, indicating that the opposite sides are congruent.

Quadrilateral PQRS with vertices P(-2,0), Q(3,1), R(4,4), S(-1,3), and Theorem 7.12:

Theorem 7.12 states that if both pairs of opposite sides of a quadrilateral are parallel and congruent, then the quadrilateral is a parallelogram.

Using the slope formula, we can calculate the slopes of the sides of quadrilateral PQRS:

Slope of PQ = (1 - 0) / (3 - (-2)) = 1/5

Slope of RS = (4 - 3) / (4 - (-1)) = 1/5

Slope of QR = (4 - 1) / (4 - 3) = 3

Slope of SP = (3 - 0) / (-1 - (-2)) = 3

The lengths of opposite sides can be calculated using the distance formula:

PQ = √((3 - (-2))² + (1 - 0)²) = √(25 + 1) = √26

RS = √((4 - 4)² + (4 - 1)²) = √(9) = 3

QR = √((4 - 3)² + (4 - 1)²) = √(1 + 9) = √10

SP = √((-1 - (-2))² + (3 - 0)²) = √(1 + 9) = √10

We can see that PQ = RS and QR = SP, indicate that the opposite sides are parallel and congruent.

Answer:

Engineer: 9.5 hr

Assistant: 4.5 hr

Step-by-step explanation:

To solve this problem, we can create and solve a system of equations.

Define the variables:

Given the engineer's time is billed at $40 per hour, and her assistant's is billed at $10 per hour, and a customer received a bill for $425 for a certain job:

Given the assistant worked 5 hours less than the engineer:

Therefore, the system of equations that represents the problem is:

\(\begin{cases}40x+10y=425\\ \quad \qquad \;\;\;y=x-5\end{cases}\)

Substitute the second equation into the first equation to eliminate y:

\(40x+10(x-5)=425\)

Solve the equation for x to find the number of hours the engineer worked:

\(\begin{aligned}40x+10(x-5)&=425\\40x+10x-50&=425\\50x-50&=425\\50x&=475\\x&=9.5\end{aligned}\)

Therefore, the engineer worked 9.5 hours.

Substitute the found value of x into the second equation and solve for y to find the number of hours the assistant worked:

\(\begin{aligned}y&=x-5\\y&=9.5-5\\y&=4.5\end{aligned}\)

Therefore, the assistant worked 4.5 hours.

The correct value of Jessica's new net salary will be $225.

To calculate Jessica's new net salary after a 5% raise, we need to first determine Sarah's gross salary. We know that Sarah's net salary is $212.50, and 15% of her gross salary is withheld each week.

Let's denote Sarah's gross salary as "G." We can set up the following equation:

G - 15% of G = $212.50

Simplifying the equation, we have:

G - 0.15G = $212.50

0.85G = $212.50

G = $212.50 / 0.85

G ≈ $250

Sarah's gross salary is approximately $250.

Now, to find Jessica's new net salary after a 5% raise, we can calculate 5% of Sarah's gross salary and subtract the withheld amount:

Jessica's net salary = Sarah's gross salary + 5% of Sarah's gross salary - 15% of Sarah's gross salary

Jessica's net salary = $250 + 0.05 * $250 - 0.15 * $250

Jessica's net salary = $250 + $12.50 - $37.50

Jessica's net salary = $225

Therefore, Jessica's new net salary will be $225.

Answer:

45° and 135°

Step-by-step explanation:

let x be the angle then its supplement is 190 - x

Given x is 3 times its supplement , then

x = 3(180 - x) ← distribute parenthesis by 3

x = 540 - 3x ( add 3x to both sides )

4x = 540 ( divide both sides by 4 )

x = 135

and 180 - x = 180 - 135 = 45

The 2 angles are 45° and 135°

This is because the given expression factors to (x+4)(x+4), which condenses to (x+4)^2.

To factor, think of two numbers that A) multiply to 16, and B) add to 8. Those values would be 4 and 4

4+4 = 8

4*4 = 16
