8 square unit to find the area of the parallelogram with vertices A(-4, 2), B(-2, 5), C(2, 3), and D(0, 0), follow these steps:

Step 1: Find the base and height vectors of the parallelogram. Let's use AB and AD as the base and height vectors, respectively.
AB = B - A = (-2 - (-4), 5 - 2) = (2, 3)
AD = D - A = (0 - (-4), 0 - 2) = (4, -2)

Step 2: Calculate the cross-product of the base and height vectors.
Cross product = AB_x * AD_y - AB_y * AD_x = (2 * -2) - (3 * 4) = -4 - 12 = -16

Step 3: Find the area by taking the absolute value of the cross product divided by 2.
Area = |Cross product| / 2 = |-16| / 2 = 8

The area of the parallelogram with vertices A(-4, 2), B(-2, 5), C(2, 3), and D(0, 0) is 8 square units.

The value of x if given expression as (x-1)(2-x)<0 will be 1 and 2.

The solution of an equation refers usually to the values of the variables involved in that equation which if substituted in place of those variable would give a true mathematical statement.

We have been given an expression as  (x-1)(2-x)<0, then the value of x can be calculated as;

(x-1)(2-x) = 0

Therefore, Using the zero product property we get;

(x-1) = 0

x = 1

Similarly,

(2-x) = 0

2 = x

Therefore, the value of x if given expression as (x-1)(2-x)<0 will be 1 and 2.

Step-by-step explanation:

In most cases, we run into the problem of arranging objects that are repeated. This often occurs when we have a word that has repeated letters.

Let us recall that permutation deals with arrangements which are distinguishable.

Hence, for the word CONCLUSION, the number of distinguishable arrangements are;

10!/2!2!2!

Given:

The quadratic equation is:

\(x^2+13x+k=0\)

\(x_1=-9\)

To find:

The value of k and \(x_1\).

Solution:

We have,

\(x^2+13x+k=0\)                ...(i)

Putting \(x=-9\), we get

\((-9)^2+13(-9)+k=0\)

\(81-117+k=0\)

\(-36+k=0\)

\(k=36\)

Putting \(k=36\) in (i), we get

\(x^2+13x+36=0\)

Splitting the middle term, we get

\(x^2+9x+4x+36=0\)

\(x(x+9)+4(x+9)=0\)

\((x+9)(x+4)=0\)

\(x=-9,-4\)

Here, \(x_1=-9\) and \(x_2=-4\).

Therefore, the required values are \(k=36\) and \(x_2=-4\).

You have to find the slope of the line. It will give you the conversion rate from inches to centimetres or the other way around.

Looking closely at the graph, or using a ruler as reference, you can estimate that 30 cm ≈ 12 in. In terms of the graph, the line very nearly passes through the point (12, 30). It also passes through the origin, (0, 0), since 0 cm = 0 in exactly.

The slope of the line is then

\(\dfrac{30\,\mathrm{cm}-0\,\mathrm{cm}}{12\,\mathrm{in}-0\,\mathrm{in}} = \dfrac{30\,\rm cm}{12\,\rm in} = \dfrac{5\,\rm cm}{2\,\rm in} = 2.5\dfrac{\rm cm}{\rm in}\)

which means that 1 in ≈ 2.5 cm.

So, if Sarah's height is 64 in, we convert this to cm and find her height is (approximately)

\(64\,\mathrm{in} \times 2.5\dfrac{\rm cm}{\rm in} = \boxed{160\,\rm cm}\)

Subtract the second part from the first part:

Answer: 4/9 ≅ 0.4444444 = four ninths. ... Then simplify the result to the lowest terms or a mixed number.

The required value of x is 22 degrees for the given figure.

Adjacent angles are a sort of additional angle. Adjacent angles share a common side and vertex, such as a corner point. Their points do not overlap in any manner.

As we know that supplementary angles are defined as when pairing of angles addition to 180° then they are called supplementary angles.:

According to the given figure, it can be written as follows:

2x + 24 + 6x - 20 = 180

8x + 4 = 180

8x = 180 - 4

8x = 176

x = 176/8

x = 22

Therefore, the required value of x is 22 degrees for the given figure.

The area that the dog can wander based on the information provided will be 931π.

From the information, we are told that the dog dog is attached to a 35-foot rope fastened to the outside corner of a fenced-in garden that measures 28 feet by 36 feet.

In this case, the dog is in an outside corner. The dog can trace 3/4 of a circle when it starts walking in a circle away form the wall.

The area that the dog can wander will be:

= 3/4(π35²) + 1/4(π(35 - 28)²)

= 3/4π(35)² + 1/4π(7)²

= (3/4 × 1225)π + (1/4 × 49)π

= 918.75π + 12.25π

= 931π

Therefore, the area that the dog can wander based on the information provided will be 931π.

A B C is the correct condition for the researcher to calculate the mean.

When a researcher collects a simple random sample of grade-point averages of statistics students, the sample mean can be treated as a value from a population having a normal distribution under the following conditions:

A. The researcher collects more than 30 samples.

B. If the population of statistics students has a normal distribution.

C. If the population of grade-point averages has a normal distribution.

Hence, options A, B, and C are correct. In order to estimate P(at least 5)

with n = 13 and p = 0.5, the following formula should be used:μ = np = (13)

(0.5) = 6.5σ = sqrt(npq) = sqrt(13 × 0.5 × 0.5) = 1.802P(at least 5) = P(X ≥

Answer:

Equation of parabola in vertex form:
y = -5( x + 1)² + 3

Equation of parabola in standard form:
y = -5x² -10x - 2

Step-by-step explanation:

The vertex form equation for a parabola is

y = a(x - h)² + k

where (h, k) is the vertex and a is a constant

Given (h, k) = (- 1, 3)
h = -1 , k = 3

y = a( x - (-1) )² + 3
y = a(x + 1)² + 3

To find a, we know the parabola passes through point(- 2, - 2). Plug in x = -2, y = -2 and solve for a

- 2 = a( -2 + 1)² + 3

-2 = a(-1)² + 3

-2 = a · 1 + 3

-2 = a + 3

Subtract 3 from both sides:

-2 - 3 = a + 3 -3

-5 = a

or

a = -5

Equation of parabola in vertex form:
y = -5( x + 1)² + 3

The standard form of this parabola is y = ax² + bx + c

Expand (x + 1)² = x² + 2 · 1 · x + 1² = x² + 2x + 1

Therefore

y = -5( x + 1)² + 3 becomes
y = -5( x² + 2x + 1) + 3

y = -5x² -10x - 5 + 3

y = -5x² -10x - 2

The given circuit consists of an EMF (electromotive force) producing voltage E(t) in volts, a resistor with resistance R in ohms, and an inductor with inductance L in henries.

The current in the circuit is measured in amperes. The switch in the circuit controls the flow of current.

Given that E(t) = 40 sin(60t) volts, L = 1H, R = 20 ohms, and I(0) = 1A, we need to find the current I(t) and the charge Q(t).

To find the current I(t), we can use Ohm's Law and the relationship between current and voltage across an inductor. Since the inductor has inductance L, we have L di/dt = E(t) - IR, where di/dt represents the derivative of current with respect to time. Rearranging the equation and substituting the given values, we can solve for I(t).

To find the charge Q(t), we can integrate the current over time. Since Q(t) represents the accumulated charge, we can integrate I(t) with respect to time.

The test statistic (6.739) is greater than the critical value (3.106), we can reject the null hypothesis and conclude that there is a significant correlation in the population between study hours and performance in the course at the 0.01 significance level.

In order to determine whether there is a correlation in the population between the study hours and performance in the course at the 0.01 significance level (a

= 0.01.), we can use the correlation coefficient of r

= 0.885 and the criterion for testing correlation in the population between two variables. We can also use Table A-6 to find the critical value for the test.The formula to test for a correlation coefficient is given Where r

= correlation coefficient, n

= sample size, and t is the test statistic.To find the critical value, we will use Table A-6. From the table, we can see that the critical value for a two-tailed test at a 0.01 significance level with 11 degrees of freedom is 3.106 (rounded to three decimal places).Since our sample size is 13, we will use 11 degrees of freedom. We can calculate the test statistic using the formula as follows. The test statistic (6.739) is greater than the critical value (3.106), we can reject the null hypothesis and conclude that there is a significant correlation in the population between study hours and performance in the course at the 0.01 significance level.
