Answer:

-1250/1 or -1250

This tells us that the car depreciated in value by $1250 every year.

Step-by-step explanation:

11,095-13,595= -2500

This is the value that the car has depreciated over 2 years (from the first year to the third year)

Since we need to find the slope we divide this value by two.

That value would be -1250

Since the value is negative, we know the car has depreciated in value. We also now know that it depreciated in value by $1250 every year

Question 7

---------------------

Work Shown:

angle B = angle D = 56

angle C = angle F = 64

The missing angle A adds with B and C to get 180

A+B+C = 180

A = 180-B-C

A = 180-56-64

A = 60

Since angles B and D are congruent, and C and F are congruent, this must mean angle A = angle E. I'm using the angle angle (AA) similarity rule.

angle E = angle A

3x+15 = 60

3x = 60-15

3x = 45

x = 45/3

x = 15

Side note: I'm not sure why your teacher marked angle E as the same as angles C and F.  They should have used another angle marker to indicate that angles A and E are the same.

================================================

Question 8

------------------------------

Work Shown:

Triangle ABC is congruent to triangle EDF. The order is important. We have A first, then B, then C for ABC. Also, we have E first, then D, then F for EDF.

Therefore, we have these three pairings

We'll first need angle C

A+B+C = 180

C = 180-A-B

C = 180-42-108

C = 30

which we'll then solve for x

angle F = angle C

4x-4 = 30

4x = 30+4

4x = 34

x = 34/4

x = 8.5

which doubles to

2x = 2*8.5

2x = 17

Answer:

There's no A so I'm going to assume you meant X

X = 23

Step-by-step explanation:

X is equal to 23, because 23 - 18 = 5

or 5 + 18 = 23

Answer: Yes

Please provide the complete parametric equations r(t) = ⟨x(t), y(t), z(t)⟩ to calculate the curvature.

Mathematical formulas known as parametric equations specify a point's coordinates in terms of one or more independent variables known as parameters. Parametric equations employ separate equations for the x and y coordinates in instead of utilising a single equation to represent points on a graph.

This makes it possible to depict curves and forms in a more flexible way. The path that the point follows can be changed by adjusting the parameter values, which enables the construction of complex curves like ellipses and spirals. Where exact control over curves and motion is necessary, parametric equations have applications in a variety of domains, such as physics, engineering, computer graphics, and animation.

To calculate the curvature, we first need the tangent vector T(t) and its derivative dT/dt. It seems that you may have accidentally left out some parts of the question, specifically the parametric equations for the curve r(t).

Answer:

To find the area of sector BOC, given angle AOC has a measure of radians, the length of arc AB is units, and the radius is 12 units, follow these steps:

1. Determine the measure of angle BOC in radians. Since angle AOC has a measure of radians, we assume angle BOC is the remaining part of the angle. However, without the actual value for angle AOC, we cannot find the measure of angle BOC.

2. Find the length of arc BC. The length of arc AB is given as units, but we need the length of arc BC to calculate the area of sector BOC. To find the length of arc BC, we need the measure of angle BOC and the radius, which is given as 12 units. Arc length (BC) = radius x angle BOC in radians. However, since we don't have the angle BOC value, we can't calculate the arc length.

3. Calculate the area of sector BOC. To find the area of sector BOC, we use the formula: Area = (1/2) x radius² x angle BOC in radians. With a radius of 12 units, the formula becomes Area = (1/2) x (12²) x angle BOC in radians. However, we don't have the value for angle BOC, so we cannot calculate the area.

Without the actual values for angle AOC and the length of arc AB, we cannot find the area of sector BOC. Please provide the missing values for a more accurate answer.

The area of sector boc where angle aoc has a measure of radians is 6 times the length of arc AB.

Using the formula for the area of a sector, which is given by:

Area = (θ/2) *\(r^2\),

where θ is the measure of the angle in radians and r is the radius.

In this case, we are given that the angle AOC has a measure of θ radians, the length of arc AB is given in units, and the radius is 12 units. Let's assume that the length of arc AB is denoted by s.

First, we need to find the value of θ. The length of an arc is related to the circumference of the circle by the formula:

s = r * θ,

where s is the arc length, r is the radius, and θ is the angle in radians.

Rearranging this formula, we have:

θ = s / r.

Substituting the given values, we have:

θ = (length of arc AB) / (radius) = s / 12.

Now we can calculate the area of sector BOC:

Area = (θ/2) *\(r^2\) = [(s / 12) / 2] * \(12^2\) = (s / 24) * 144 = 6s.

Therefore, the area of sector BOC is 6 times the length of arc AB.

when you complete the square for a quadratic, you r answer can come in the form (x+p)^2+q.

in this form, p is the opposite of the x coordinate.

and q is the same as the y coordinate.

to get p and q from this, we find the opposite of the x coordinate and use the y coordinate we are given, and plug them into this equation.

we get: (x-2)^2+1

lets complete the equation now.

(x-2)^2 = x^2 - 4x + 4, then add the one we left out = x^2 - 4x + 5.

now our equation is in the same format as y=x^2+ax+b so we can just pull out the A and B which gives us:

Step-by-step explanation:

There are 347,760 ways to arrange the 9 balls of colors red, green, and blue such that no two blue balls are next to each other. The principle of inclusion-exclusion is used to solve this problem.

First, we calculate the total number of ways to arrange the 9 balls without any restrictions. This can be done using the formula for permutations of n objects, which is n! (n factorial) in this case. So we have:

9! = 362,880

Next, we calculate the number of ways to arrange the balls with two blue balls next to each other. We can treat the two blue balls as a single object and arrange the remaining 7 objects in 7! ways. However, we also need to consider the 3 different ways to choose which two blue balls are next to each other. So we have:

3 x 7! = 15,120

Finally, we need to subtract the number of arrangements with two blue balls next to each other from the total number of arrangements to get the number of arrangements without any two blue balls next to each other:

9! - 3 x 7! = 347,760

Therefore, there are 347,760 ways to arrange the 9 balls of colors red, green, and blue such that no two blue balls are next to each other.

Therefore, the probability of getting exactly 5 correct out of 10 when guessing randomly is 0.2461.

This is a binomial probability problem, where each question is a trial with a probability of success (getting the correct answer) of 1/4, since there are four possible answers and only one is correct. We want to find the probability of getting exactly 5 correct out of 10, so the number of trials is n = 10 and the number of successes we want is k = 5.

The formula for the probability of getting k successes in n trials, each with a probability of success p, is:

P(k) = (n choose k) * p^k * (1-p)^(n-k)

where (n choose k) is the number of ways to choose k successes out of n trials, and is calculated as n! / (k! * (n-k)!).

Plugging in the values for this problem, we get:

P(5) = (10 choose 5) * (1/4)^5 * (3/4)^5

= (252) * (1/4)^5 * (3/4)^5

= 0.2461 (rounded to four decimal places)

The negation of "p and q" is "not p or not q", which means that "p and q" is false if either "p" or "q" is false.

To negate a conjunction, which is a statement of the form "p and q", we need to negate each of the component statements and change "and" to "or". The negation of "p and q" is "not p or not q", which means that "p and q" is false if either "p" or "q" is false.

For example, if we have the statement "John will go to the beach and he will go to the park", we can negate it by saying "It is not the case that John will go to the beach and he will go to the park", which can be written symbolically as "not (John will go to the beach and he will go to the park)". Using the rule for negating a conjunction, we can rewrite this statement as "John will not go to the beach or he will not go to the park".

Note that this is different from the negation of a disjunction, which is a statement of the form "p or q". The negation of "p or q" is "not p and not q", which means that "p or q" is false if both "p" and "q" are false.
