Answer:

-3

Step-by-step explanation:

x - y = 12 is the same as -2x = -24 - 2y

                                         2x = 27 + 3y

                                     +  --------------------

                                         0 =   3  +  y

                                        -3 = y

Answer:

The center of this circle is (5, -4) and the radius is 1.

Step-by-step explanation:

First regroup these terms according to x and y :

x^2 - 10x + y^2 + 8y = -40

Next, complete the square for x^2 - 10x:  x^2 - 10x + 5^2 - 5^2.

and the same for y^2 + 8y:  y^2 + 8y + 16 - 16

Substituting these results into x^2 - 10x + y^2 + 8y = -40, we get:

x^2 - 10x + 5^2 - 5^2 y^2 + 8y + 16 - 16 = -40.

Next, rewrite x^2 - 10x + 25 and y^2 + 8y + 16 as squares of binomials:

Then x^2 - 10x + 5^2 - 5^2 y^2 + 8y + 16 - 16 = -40 becomes:

(x - 5)^2 + (y + 4)^2 - 25 - 16 = -40, or:

(x - 5)^2 + (y + 4)^2 = 1

This equation has the form (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center and r is the radius.  Matching like terms, we get h = 5, k = -4 and r = 1.

The center of this circle is (5, -4) and the radius is 1.

Answer:

Center (5,-4) Radius = 1

Step-by-step explanation:

Put it in the form of the standard circle equation after dividing everything by 2. (-10x/2=-5x) (8y/2=4y) Since the radius wasn't given, it's just going to be a 1.

(x-5)^2+y(-(-4))^2 = 1^2

Hence, center (5, -4) and radius 1.

Using elimination method, the solution of the system of equation is as follows:

x = 1 and y = 1

The system of equation can be solved using different method such as elimination method, substitution method and graphical method.

Therefore, let's solve the system of equation by elimination method.

-9 + 5y = -4x

-11x = -20 + 9y

Rearrange the equations.

4x + 5y = 9

11x + 9y = 20

multiply equation(i) by 11 and multiply equation(ii) by 4

44x + 55y = 99

44x + 36y = 80

subtract equation(ii) from equation(i)

19y = 19

y = 19 / 19

y = 1

Hence,

4x = 9 - 5(1)

4x = 4

x = 4 / 4

x = 1

Therefore,

x = 1 and y  = 1

Answer:

32 degrees

Step-by-step explanation:

119+29=148

180-148=32

Answer:

Step-by-step explanation:

Always remember that a triangles inner angles will always add up to 180 degrees.

So to find the missing angle you would use this equation

180 = angle + angle + angle

In this problem you know 2 of the angles, so input them into the equation above.

180 = 119 + 29 + angle

The next step is to subtract the known angles from 180 degrees.

You can add them both together first ... so 119 + 29 = 148

Now you can subtract 148 from 180, which = 32

So your missing angle is 32 degrees

Final equation should be a true math statement 180 = 119 + 29 + 32

The graph is only something to waste your time,use the equation to find the answers for each part

TOTAL AMOUNT (t) can be calculated by subtracting 10 from the ORIGINAL PRICE (p).

That is the equation t=p-10

The number of outcomes where team A wins 2 games, loses 3 games, and ties 2 games is 210.

In problem 1, there are three possible outcomes for each game: win, loose, or tie.

So, for seven games, there are 3x3x3x3x3x3x3 = 2187 different outcomes.

For problem 2, we need to calculate the number of ways that team A can win two games, lose three games, and tie two games.

To do this, we can use the binomial coefficient formula, which is (n choose k) = n!/(k!(n-k)!).

In this case, n=7 (the total number of games), k=2 (the number of games that team A wins), and m=2 (the number of games that team A ties).

So the number of outcomes where team A wins 2 games, loses 3 games, and ties 2 games is (7 choose 2)(5 choose 3)(2 choose 2) = 210.

We can determine coordinates if point t is between points u and v by checking if u < t < v or v < t < u.

To determine if point t is between points u and v, we need to compare their coordinates. If u < v, then point t is between points u and v if and only if u < t < v. On the other hand, if v < u, then point t is between points u and v if and only if v < t < u.

Whether or not point t is between points u and v depends on the relationship between the coordinates of u and v. If u < v, t must fall between them, and if v < u, t must also fall between them.

CS responding of 81 refers to the response to a conditioned stimulus. A suppression ratio of zero means no fear response is observed, indicating no learned association between the conditioned stimulus and the aversive outcome.


“CS responding” refers to the response elicited by a conditioned stimulus (CS). A conditioned stimulus is a neutral stimulus that, through repeated pairing with an unconditioned stimulus (UCS), acquires the ability to elicit a conditioned response (CR). The CS responding value represents the level or frequency of the conditioned response.
Now, let’s address the concept of a suppression ratio. In fear conditioning experiments, a common way to measure fear is through a suppression ratio, which is calculated by dividing the number of responses emitted during the CS presentation by the total number of responses emitted during a specific period, usually including both the CS and a baseline period.

A suppression ratio of zero indicates that no suppression of responding occurs during the presentation of the conditioned stimulus. This means that the individual is not showing any reduction in their responding when the CS is presented compared to the baseline period.
In terms of both responding and fear, a suppression ratio of zero suggests that the individual is not associating the CS with the aversive outcome (UCS) and does not exhibit any fear response. Essentially, there is no behavioral evidence of conditioned fear or a learned association between the CS and the aversive stimulus.

The value of x is 8 in.

A prism is a three-dimensional object.

There are triangular prism and rectangular prism.

We have,

Length = x + 4

Width = x

Height = x - 2

The volume of the rectangular prism = 385 in³

The volume of the rectangular prism = length x width x height

Now,

length x width x height = 385

(x + 4) x (x - 2) = 385

(x + 4) (x² - 2x) = 385

x³ - 2x² + 4x² - 8x = 385

x³ + 2x² - 8x = 385

This is a cubic polynomial.

f(x) = x³ + 2x² - 8x - 385

f(x) = a³ + bx² + cx + d = 0

Using the calculator we get,

In the discrete metric space defined on the real numbers, every subset (A) is both open and closed.

In the given context, where the real numbers are equipped with the discrete distance function, we have (d(x, y) = 0) if and only if (x = y), and (d(x, y) = 1) if (x \neq y).

Now let's consider a subset (A \subset \mathbb{R}). We want to determine when (A) is an open set, closed set, or neither.

Open Sets:

In this discrete metric space, every singleton {x} (a set containing a single element) is an open set because for any (x \in A), there exists a neighborhood around (x) that contains no other elements of (A) (except itself) due to the definition of the discrete metric.

So, if (A) consists of only isolated points (singletons), i.e., (A = {x_1, x_2, x_3, \ldots}) where (x_i \neq x_j) for (i \neq j), then (A) is an open set.

Closed Sets:

In this discrete metric space, any subset (A) of the real numbers can be considered closed because the complement of (A) is also open. This is because the neighborhoods around each point in (\mathbb{R} \setminus A) contain only points from (\mathbb{R} \setminus A).

Therefore, any subset (A) of (\mathbb{R}) is closed.

Neither Open nor Closed Sets:

There are no subsets in this metric space that are neither open nor closed since every subset is either open or closed.

The formula for calculating the effective annual rate of interest with quarterly compounding is:

(1 + r/4)^4 - 1 = A/P

where r is the quarterly interest rate, A is the final amount, and P is the principal.

In this case, P = $2,000, A = $3,000, and the time period is 7 years or 28 quarters.

So we have:

(1 + r/4)^4 - 1 = 3000/2000

(1 + r/4)^4 = 1.5

1 + r/4 = (1.5)^(1/4)

r/4 = (1.5)^(1/4) - 1

r = 4[(1.5)^(1/4) - 1]

To get the effective annual rate, we need to convert the quarterly rate to an annual rate by multiplying by 4:

effective annual rate = 4[(1.5)^(1/4) - 1] ≈ 8.84%

Therefore, the effective annual rate of interest at which $2,000 will grow to $3,000 in seven years if compounded quarterly is approximately 8.84%, rounded to 2 decimal places.

Answer: 12.65

Step-by-step explanation:

Ive never solved a problem like this, but this is how I would solve it. You first want to find the height of the triangle by using the Pythagorean theorem. Solve for the height by using the left triangle.

\((4\sqrt{2} )^2=4^2+b^2\\32=16+b^2\\16=b^2\\b=4\)

b is the height, the dotted line, of both triangles. Now do the Pythagorean theorem on the right triangle to find the value of x

\(12^2+4^2=x^2\\144+16=x^2\\160=x^2\\x=\sqrt{160} \\x=12.649=12.65\)

From the situation described in the problem, we have that:

a) The sinusoidal function that models the depth of the water is given by: D(t) = 2sin(π/6x) + 3.

b) After 4 hours, the depth is of 4.732 meters.

The sine function is defined as follows:

g(x) = a sin(bx+c)+d.

The coefficients are defined as follows:

For this problem, the minimum value is of 1 and the maximum value is of 5, having a difference of 4, hence the amplitude is found as follows:

2a = 4 -> a = 2.

A standard sine function with an amplitude of 2 varies between -2 and 2, while this varies between 1 and 5, meaning that it had a vertical shift up 3 units, and d = 3.

The period is of 12 hours, hence:

2π/B = 12

12B = 2π

B = π/6.

The function has no phase shift, hence c = 0 and the function is given by:

D(t) = 2sin(π/6x) + 3.

From point (4, 4.732) on the graph of the function, after 4 hours, the depth is of 4.732 meters.

Polynomials

A polynomial can be built if we know its zeros, also called roots

Suppose p,q, and r are the roots of a polynomial of degree 3, then:

p(x)=a(x-p)(x-q)(x-r)

Where a is a real number different from 0

Note we are only given two roots:

p=1

q=i

recall that i is the base of the complex numbers, that is:

The third root comes when we recall that, if a polynomial has real coefficients, the complex roots come in conjugate pairs, i.e. if a+bi is one root of the polynomial, then a-bi is also a root of the polynomial.

Thus, the other root is the conjugate of q:

r=-i

Now we have all the roots, we just apply the above equation to find:

p(x)=a(x-p)(x-q)(x-r)
