A triangle has sides that measure 3cm, 4cm, and 5 cm. What type of triangle is it?​

For the given function, the domain is D : { x ≥ 7} and the range is R: { y ≥ 9}

Here we have a square root, remember that the argument of the square root must be equal or larger than zero, so the domain is such that:

x - 7 ≥ 0.

Solving for x we get:

x ≥ 0 + 7

Then the domain is:

x ≥ 7

To get the range, we evaluate in the minimum of the domain:

f(7) = √(7 - 7) + 9 = 9

Then the range is the set of all values larger than 9, because the function is increasing.

So the range is R: y ≥ 9.

Therefore, the measure of the central angle whose radii define the given arc is approximately 83.077 degrees.

The length of an arc on a circle is given by the formula:

Arc Length = (Central Angle / 360°) * Circumference

In this case, we know the arc length is 6π centimeters, and the radius of the circle is 13 centimeters. The circumference of the circle can be calculated using the formula:

Circumference = 2π * Radius

Substituting the radius value, we get:

Circumference = 2π * 13

= 26π

Now we can use the arc length formula to find the central angle:

6π = (Central Angle / 360°) * 26π

Dividing both sides of the equation by 26π:

6π / 26π = Central Angle / 360°

Simplifying:

6 / 26 = Central Angle / 360°

Cross-multiplying:

360° * 6 = 26 * Central Angle

2160° = 26 * Central Angle

Dividing both sides by 26:

2160° / 26 = Central Angle

Approximately:

Central Angle ≈ 83.077°

Answer:

In Tyler scale, 1 inch equals 4 ft.

Step-by-step explanation:

Giving the following information:

Tyler made a scale drawing of a 24 ft longboat. In his drawing, the boat was 6 inches.

We know that 1 ft is 12 inches. Therefore, 24 ft:

24*12= 288 inches

Now, we have to determine the scale that Tyler used.

1 Tyler inch= 288/6= 48 inches

In ft:

1 Tyler inch= 48/12= 4 ft

In Tyler scale, 1 inch equals 4 ft.

Answer:

2n^2+n-3, 663

Step-by-step explanation:

This is the same as having (1, 0), (2, 7), (3, 18), (4, 33), (5, 52)

We know that this is a parabola because the difference of the differences is a constant:

7, 11, 15, 19

4, 4, 4

this means the nth term is an^2+bn+c

we know a = 2 because the 2a is the difference's difference of 4, 4/2 = 2

now we plug in points to find the others:

2*1^2 + b*1 + c = 0 = 2 + b + c

so b + c = -2

2*2^2 + b*2 + c = 7 = 8 + 2b + c

so 2b + c = -1

2b + c - (b + c) = -1 - - 2 = b = 1

so b = 1

b + c = -2 = 1 + c

c = -3

we put these together to get our answer

2n^2 + n - 3

for 18 this is 2 * 18^2 + 18 - 3 = 663

A) Pairwise ranking is an essential part of the weighted ranking method.

Pairwise ranking is one of the analytic techniques covered so far in class that is an essential part of the weighted ranking method.

Pairwise ranking, also known as pairwise comparison, is a process for comparing different options. Each option is compared to every other option to determine which one is better.

This is done by considering two options at a time and evaluating which one is preferred over the other, and then assigning a value to each option based on how many times it was chosen over the others.

The weighted ranking method, also known as the analytic hierarchy process (AHP), is a decision-making method that involves breaking down a complex problem into smaller, more manageable pieces, prioritizing them, and then making a decision based on the priorities.

Pairwise ranking is an essential part of this process because it helps to determine the relative importance of each option and thus how much weight should be given to each option in the final decision.

Hence, Pairwise Ranking is an essential part of the weighted ranking method.

Answer:

x<4

Step-by-step explanation:

To solve for x in the inequality equation, the terms should be rearranged such that x is on one side and integers are on the other side.

First, expand 4(x-3).

This will obtain:

\(4x - 12 < 2x - 4\)

Now, shift x terms and integers on each side.

\(4x - 2x < - 4 + 12\)

After simplifying, it will get:

\(2x < 8\)

Finally, we can solve for x.

\(x < 4\)

The cost of the car in U.S. dollars comes out to approximately 14,498.37 USD.

To find the cost of the car in U.S. dollars, you need to divide the cost in British pounds by the conversion rate.
The car costs 8,930 British pounds, and the conversion rate is 1 U.S. dollar = 0.6158 British pounds. So, to find the cost in U.S. dollars, you would use the following formula:
Cost in USD = (Cost in British Pounds) / (Conversion Rate)
Cost in USD = (8,930) / (0.6158)

When you perform the calculation, the cost of the car in U.S. dollars comes out to approximately 14,498.37 USD.

A collection of paired data consists of the number of years that students have studied Spanish and their scores on a Spanish language proficiency test.  r = 0.91; There is a significant linear correlation. Option A

Generally, The value of the linear correlation coefficient r is given in the display as 0.91. To determine whether there is significant linear correlation between years of study and test scores, we need to conduct a hypothesis test.

The null hypothesis for this test is that there is no linear correlation between years of study and test scores, and the alternative hypothesis is that there is linear correlation.

To test the null hypothesis, we can use the value of r and the sample size (10 pairs of data) to calculate a p-value. If the p-value is less than our significance level of 0.05, we can reject the null hypothesis and conclude that there is significant linear correlation between the variables.

Since r is given as 0.91 and the sample size is 10, we can conclude that there is significant linear correlation between years of study and test scores.

Firstly, we will find the third angles of both triangles,

The sum of angles in a triangle is 180 degrees.

If we know that two angles of one triangle are 112° and 39°

Let the third angle be x

The third angle is 29 degrees

And two angles of another triangle are 39° and 29°

Let the third angle be y

The third angle is 112 degrees

Two triangles are similar if their corresponding angles are equal.

Since, their corresponding angles are equal

Hence, then the two triangles must be similar (option d)

The probability that Marshall wins a prize on his second spin =  0.1875

Consider an event X = the number of spins until Marshall wins a prize.

Given that a prize wheel with 4 segments of equal size, one of which is labeled winner.

So, the sample space n = 4

For given event x, the possible outcomes = 1

Using the formula of probability,

p = x/n

p = 1/4

p = 0.25

So, the probability of success p = 0.25

q = 1 - p

q = 1 - 0.25

q = 0.75

To find the probability that Marshall wins a prize on his 2nd spin.

Using formula, \(P(X = k) = (1 - p)^{k-1}p\)

For  k = 2,

\(P(X = 2) = (1 - 0.25)^{2-1}\times 0.25\)

P(X = 2) = 0.75 × 0.25

P(X = 2) = 0.1875

The formula for the perimeter of the sector of a circle is given below :

Step-by-step explanation:

Perimeter of sector = radius + radius + arc length

Perimeter of sector = 2 radius + arc length

Arc length is calculated using the relation :

Arc length = l = (θ/360)  × 2πr

Therefore,

Perimeter of a Sector = 2 Radius + ((θ/360)  × 2πr )

Answer:
