Answer:

area = 88 yd²

Step-by-step explanation:

area = 1/2(b1 + b2)h = 1/2(9 + 13)(8) = 88 yd²

Answer:

88 yd^2.

Step-by-step explanation:

Area of a trapezoid = 1/2 * h * (a + b) where h = height, a and b are lengths of 2 parallel side.

Area = 1/2 * 8(9+13)

= 4 * 22

= 88 yd^2.

The measure of angle DAB in the given quadrilateral can be calculated as: 109°.

To find the measure of an angle in a quadrilateral, you need to use the fact that the sum of all angles in a quadrilateral is always equal to 360 degrees.

Using the above fact stated, we can add up the three known angles in the given quadrilateral and then subtract it from 360 degrees to find the measure of angle DAB.

Thus, we have:

m<DAB = 360 - (90 + 97 + 64)

m<DAB = 360 - 251

m<DAB = 109°

The discount is 75% off the original price of $185.

To find the amount of the discount, we can multiply the original price by 0.75:

$185 x 0.75 = $138.75

Therefore, the dress has been discounted by $138.75.

To find the sales price, we can subtract the discount from the original price:

$185 - $138.75 = $46.25

Therefore, the sale price of the dress is $46.25.

if the password is alphabetic only, not case-sensitive, and has seven characters, there are a total of \(26^7\) possible combinations.

Since the password is alphabetic only and not case-sensitive, it means that there are 26 possible choices for each character of the password, corresponding to the 26 letters of the alphabet. The fact that the password is not case-sensitive means that uppercase and lowercase letters are considered the same.

For each character of the password, there are 26 possible choices. Since the password has seven characters, the total number of possible combinations is obtained by multiplying the number of choices for each character together: 26 × 26 × 26 × 26 × 26 × 26 × 26.

Simplifying the expression, we have 26^7, which represents the total number of possible combinations for the password.

The standard deviation of the heights of the dogs is approximately 42 mm.

To calculate the standard deviation of the heights of the dogs, we first need to calculate the mean height. We can do this by adding up the heights and dividing by the number of dogs:

mean height = (400 + 370 + 470 + 330 + 500) / 5 = 414 mm

Next, we need to calculate the variance, which is the average of the squared differences between each height and the mean height. We can do this using the formula:

variance = (1/n) \(\times\) Σ (xi - x\()^2\)

where n is the number of observations, xi is the height of the ith dog, and x is the mean height.

Using this formula, we get:

variance =\((1/5) \times ((400-414)^2 + (370-414)^2 + (470-414)^2 + (330-414)^2 + (500-414)^2)\)

= \((1/5) \times (196 + 1764 + 2304 + 1296 + 324)\)

= 1776

Finally, the standard deviation is the square root of the variance:

standard deviation = \(\sqrt{(variance)}\) =\(\sqrt{(1776) }\) = 42

Therefore, the standard deviation of the heights of the dogs is approximately 42 mm.

The statement "the basic structure of an argument in formal logic is called a syllogism" is false. While a syllogism is a common type of argument in formal logic, it is not the only structure that exists.

A syllogism consists of three parts: two premises and a conclusion. The premises are statements or propositions that serve as evidence or reasons, and the conclusion is the logical inference drawn from the premises. For example:

Premise 1: All mammals are animals.
Premise 2: All dogs are mammals.
Conclusion: Therefore, all dogs are animals.

However, there are other types of arguments in formal logic, such as hypothetical syllogisms, disjunctive syllogisms, and categorical syllogisms. Each of these argument structures has its own set of rules and patterns that govern how the premises and conclusion are constructed.

In summary, while a syllogism is one type of argument structure in formal logic, it is not the only one. There are various other structures that can be used to construct valid arguments.

The average score provides a general benchmark that represents the overall performance of the exam takers as a whole, independent of their hair length or any other unrelated characteristics.

The correlation between a person's hair length and their score on the exam being nearly zero indicates that there is no significant relationship between these two variables. Therefore, when your friend shaves his head, it does not provide any specific information about his exam score. In such a scenario, the best guess of what he scored on the exam would be the average score of all exam takers.

Hair length and exam performance are unrelated factors, and the absence of correlation suggests that hair length does not serve as a reliable predictor of exam scores. The nearly zero correlation indicates that the two variables do not exhibit a consistent pattern or trend. Consequently, shaving one's head does not offer any insight into their exam performance.

In the absence of any other information or factors that could help estimate your friend's score, resorting to the average score of all exam takers becomes the best guess. The average score provides a general benchmark that represents the overall performance of the exam takers as a whole, independent of their hair length or any other unrelated characteristics.

The set of points that includes all of the solutions for \(y = 5/2x + 3/2\) is \((x, 5/2x + 3/2)\) for all real numbers.

The set of points that includes all of the solutions for the given equation is \((x, 5/2x + 3/2)\) for all real numbers. This is because any point on this line will satisfy the equation \(y = 5/2x + 3/2\), which means that any solution to the equation will be included in this set of points.

Alternatively, we can find the equation of the line passing through the points (-1, -1) and (1, 4) and confirm that it is the same as the equation \(y = 5/2x + 3/2\).

Using the two-point form of a linear equation, the slope of the line passing through the two points is:

\(m = (y2 - y1) / (x2 - x1) = (4 - (-1)) / (1 - (-1)) = 5/2\)

Using the point-slope form of a linear equation with the slope and one of the points:

\(y - y1 = m(x - x1)\)

\(y - (-1) = (5/2)(x - (-1))\)

\(y + 1 = (5/2)(x + 1)\)

\(y = (5/2)x + (5/2) - 1\)

\(y = (5/2)x + (3/2)\)

This is the same equation as \(y = 5/2x + 3/2\), so we know that the set of points that includes all of the solutions is \((x, 5/2x + 3/2)\) for all real numbers.

Answer:

The height equation is:

h(t)=-16t^2 +100t+10

A) To find the maximum height, we must find the time where the velocity is 0, so we must derive it with respect to the time.

v(t) = -2*16*t + 100 = 0

       t = 100/(2*16) = 3.125s

Now we put this time in our height equation:

h(3.125s) = -16*3.125^2 + 100*3.125 + 10 = 166.25 ft.

B) The lowest heigth of the potato will be h = 0ft, when the potato hits the ground.

C) the lowest time that works for that function is t = 0s, when the potato is fired by the gun.

D) the maximum time can be finded when the potato hits the ground, afther that point the equation does not work anymore, let's find it,

h(t) = 0 = -16t^2 +100t+10

we can solve it using Bhaskara's equation:

\(t = \frac{-100 +- \sqrt{100^2 +4*16*10} }{-2*16} = \frac{-100 +- 103.2}{-32}\)

So the two solutions are:

t = 6.3s

t = -0.1s

We need to chose the positive time, as we already discused that the minimum time that works for the equation is t = 0s.

so here the answer is t = 6.3s

E) the domain is  0s ≤ t ≤ 6.3s

The range is 0ft ≤ h ≤ 166.25 ft.

2. You can solve for the slant height, s by applying Pythagorean's theorem.

3. To get from the base of the cone to the top of the hill, an ant has to crawl 29 mm.

In Mathematics and Geometry, the volume of a cone can be calculated by using this formula:

Volume of cone, V = 1/3 × πr²h

Where:

By substituting the given parameters into the formula for the volume of a cone, we have the following;

8792 =  1/3 × 3.14 × 20² × h

26,376 =  3.14 × 400 × h

Height, h = 26,376/1,256

Height, h = 21 mm.

Question 2.

In order to solve for the slant height, s, we would have to apply Pythagorean's theorem since the height of the cone has been calculated above.

Question 3.

Answer:

The information that we have is:

"The graph of y=-1/2x+2 is positive over the interval negative infinity and 4 and negative over the interval 4 and infinity."

Now, i guess that the question is:

"What happens on the graph when x = 4 ?"

Well, if for values of x smaller than 4 the graph is negative and for values of x larger than 4 the graph is positive, this must that the graph must cross the x-axis at some point, then with only that information, we can conclude that the graph is equal to zero when x = 4.

But we could also test it with the equation:

y = -(1/2)*x + 2

if we replace the x by a 4.

y = -(1/2)*4 + 2 = -2 + 2 = 0.

Then our previous hypothesis was correct.
