Step-by-step explanation:

Answer:

Option B: [tex](1, -1)[/tex]

Step-by-step explanation:

The two equations are linear simultaneous equations, which can be solved by either the substitution, elimination or graphical method.

Substitution method:

Formulate an expression for x in terms of y by isolating x and making it the subject of the equation:

   [tex]x + 2y = -1[/tex]

                  ∴ [tex]x = -2y -1[/tex] —— (equation i)

                     [tex]2x - 3y = 5[/tex] ——- (equation ii)

Substitute (equation i) in (equation ii) to solve for y:

                                      [tex]2(-2y -1) - 3y = 5[/tex]

Expand the brackets or parenthesis using the Distributive Law:

                                       [tex]-4y -2 -3y = 5[/tex]

Bring all the like terms together. Isolate the y terms together on one side of the equation and move all the other terms to the other side:

[tex]-4y -3y = 5 + 2[/tex]

= [tex]-7y = 7[/tex]

= [tex]y = -\frac{7}{7}[/tex]

∴ y = [tex]-1[/tex]

Substitute this calculated value of y into any of the equations to solve for x:

      [tex]x = -2(-1) - 1[/tex]

         [tex]= 2 - 1[/tex]

   ∴ x = [tex]1[/tex]

Together these x and y values form an ordered pair. In addition, this ordered pair is a solution to both the equations and also considered the point of intersection of the two equations

∴ Option B: [tex](1, -1)[/tex]

Simplifying, the exponents expression, we have 63y/xu⁴

Exponents are the powers to which a particular number is raised.

Given the expression 3y⁻⁴ . 3y⁵x⁸u⁻⁵.7x⁻⁹. To simplify the expression, we use the product rule of exponents which states that for a given base x, xᵃ xᵇ = xᵃ⁺ᵇ.

So, applying this rule to the expression and collecting common bases, we have that

3y⁻⁴ . 3y⁵x⁸u⁻⁵u.7x⁻⁹ = 3y⁻⁴ × 3y⁵ × x⁸ × 7x⁻⁹ × u⁻⁵ × u

= 3 × 3 × y⁻⁴ × y⁵ × 7 × x⁸ × x⁻⁹ × u⁻⁵ × u

Applying the product rule, we have that

= 3 × 3 × y⁻⁴ ⁺ ⁵ × 7 × x⁸ ⁺(⁻⁹) × u⁻⁵ ⁺ ¹

= 3 × 3 × y⁻⁴ ⁺ ⁵ × 7 × x⁸ ⁻ ⁹ × u⁻⁵ ⁺ ¹

= 3 × 3 × y × 7 × x⁻¹ × u⁻⁴

= 3 × 3 × 7 × y × x⁻¹ × u⁻⁴

Using the reciprocal rule that x⁻ⁿ = 1/xⁿ, we have that

= 3 × 3 × 7 × y × x⁻¹ × u⁻⁴

= 63 × y × 1/x × 1/u⁴

= 63y/xu⁴

The solution to the system of equations is x = 34.5, y = 19.

None of the operations that can be performed on these equations violate the rules of the elimination method, so they are all allowed.

To solve the system of equations using the elimination method, you can multiply equation 2 by 2 to obtain:

-2x + 4y = 26 (equation 2, multiplied by 2)

Then, you can add this equation to equation 1 to eliminate the x variable:

(2x - 3y) + (-2x + 4y) = 12 + 26

Simplifying and solving for y, you get:

y = 19

Substituting this value of y into either equation, you can solve for x:

Therefore , the solution of the given problem of probability comes out to be  probability of  not experiencing either symptom is 0.05.

Calculating the likelihood that a statement is true or that an event will take place is the focus of probability theory, a branch of mathematics. Any number range between 0 and 1, where 1 is frequently used to describe certainty and 0 is commonly used to denote possibility, can be used to represent chance. A probability diagram shows the likelihood that a particular event will occur.

Here,

To determine if the two symptoms are independent, we need to check if the probability of one symptom changes depending on whether the other symptom is present or not.

P(pain | swelling) = 40% / 75% = 0.533

P(pain | no swelling) = 20% / 25% = 0.8

Since the conditional probabilities are not equal, the two symptoms are dependent.

(c) The probability that the victim will experience at least one of these symptoms is the probability of experiencing pain, swelling, or both. This can be calculated as:

P(pain or swelling) = P(pain) + P(swelling) - P(pain and swelling)

= 60% + 75% - 40%

= 95%

So the probability of experiencing at least one of these symptoms is 95%.

(d) The probability that a victim will have intense pain given that they have swelling is the conditional probability:

P(pain | swelling) = 40% / 75%

= 0.533

So the probability of having intense pain given that there is swelling is 0.533.

(e) The probability that a victim will experience pain but not swelling can be calculated as:

P(pain and no swelling) = P(pain) - P(pain and swelling)

= 60% - 40%

= 20%

So the probability of having intense pain without swelling is 20%.

(f) The probability that a victim will not experience either symptom is the complement of the probability of experiencing at least one symptom:

P(neither pain nor swelling) = 1 - P(pain or swelling)

= 1 - 0.95

= 0.05

So the probability of not experiencing either symptom is 0.05.

The tens digit is 8, and the units digit is 9 (since y = x + 1). Therefore, the original number is 89.

In mathematics, an equation is a statement that asserts the equality of two expressions. An equation contains one or more variables, which are unknown values that can vary or change. The variables are usually represented by letters such as x, y, or z. The expressions on either side of the equals sign can be constants, variables, or functions of variables.

The simplest form of an equation is a linear equation, which can be represented as ax + b = c, where a, b, and c are constants and x is a variable. To solve a linear equation, we need to find the value of the variable that makes the equation true. This is done by performing arithmetic operations on both sides of the equals sign to isolate the variable.

Equations can also be more complex, involving multiple variables, powers, and functions. In such cases, algebraic techniques such as factoring, substitution, and solving systems of equations may be required to find the solution.

Equations are used to describe relationships between variables in many fields of study, including physics, chemistry, economics, and engineering. They are also used in everyday life, such as in calculating the cost of a purchase after applying a discount, or determining the amount of time it takes to travel a certain distance

Let's represent the tens and units digits with x and y, respectively. According to the problem statement, we have two equations:

y = x + 1 (the units digit is one more than the tens digit)

10x + y + 10y + x = 187 (the sum of the original number and the reversed number is 187)

Simplifying the second equation, we get:

11x + 11y = 187

x + y = 17 (dividing both sides by 11)

Substituting y = x + 1 into the second equation, we get:

x + (x + 1) = 17

2x + 1 = 17

2x = 16

x = 8

So the tens digit is 8, and the units digit is 9 (since y = x + 1). Therefore, the original number is 89.

Answer:

a. The sequence x_n = n^-2 converges quadratically to zero as n approaches ∞.

b. The sequence x_n = 2^-n converges linearly to zero as n approaches ∞.

c. The sequence x_n = 2^-2n converges quadratically to zero as n approaches ∞.

d. The sequence x_n = 2^-a_n with a_0 = a_1 = 1 and a_n+1 = a_n+a_n-1 for n≥2 converges superlinearly to zero as n approaches ∞.

Step-by-step explanation:

a. The sequence {x_n} = {n^(-2)} converges quadratically to zero as n approaches ∞.

To see this, we can calculate the limit of the ratio between consecutive terms:

lim_{n -> ∞} (x_{n+1} / x_n) = lim_{n -> ∞} ((n+1)^(-2) / n^(-2)) = lim_{n -> ∞} ((n / (n+1))^2) = 1

Since the limit is equal to 1, we know that the convergence rate of {x_n} is at least quadratic. This can also be seen from the fact that the error in the nth term is O(n^(-3)), which is smaller than the error in a linearly converging sequence (which is O(n^(-1))).

b. The sequence {x_n} = {2^(-n)} converges linearly to zero as n approaches ∞.

To see this, we can calculate the limit of the ratio between consecutive terms:

lim_{n -> ∞} (x_{n+1} / x_n) = lim_{n -> ∞} (2^(-(n+1)) / 2^(-n)) = lim_{n -> ∞} (1/2) = 1/2

Since the limit is strictly less than 1, we know that the convergence rate of {x_n} is linear.

c. The sequence {x_n} = {2^(-2n)} converges quadratically to zero as n approaches ∞.

To see this, we can calculate the limit of the ratio between consecutive terms:

lim_{n -> ∞} (x_{n+1} / x_n) = lim_{n -> ∞} (2^(-(2(n+1))) / 2^(-2n)) = lim_{n -> ∞} (1/4) = 1/4

Since the limit is equal to 1/4, we know that the convergence rate of {x_n} is at least quadratic. This can also be seen from the fact that the error in the nth term is O(n^(-2)), which is smaller than the error in a linearly converging sequence (which is O(n^(-1))).

d. The sequence {x_n} = {2^(-a_n)}, where a_0 = a_1 = 1 and a_{n+1} = a_n + a_{n-1} for n >= 2, converges superlinearly to zero as n approaches ∞.

To see this, we can use the fact that a_n grows exponentially with n. We can prove by induction that a_n >= phi^n, where phi is the golden ratio. Since the terms of {x_n} are decreasing and bounded below by 0, they must converge to a limit L. Taking the limit of the ratio of consecutive terms, we get:

lim_{n -> ∞} (x_{n+1} / x_n) = lim_{n -> ∞} (2^(-a_{n+1}) / 2^(-a_n)) = lim_{n -> ∞} (2^(-a_n - a_{n-1})) = 0

This shows that the convergence rate of {x_n} is superlinear.

Step-by-step explanation:

To solve this problem, we can use proportions.

If a 28 g serving of almonds has 160 calories, then:

28 g / 160 calories = 45 g / x calories

where x is the number of calories in a 45 g serving of almonds.

We can cross-multiply and solve for x:

28 g * x = 160 calories * 45 g

x = (160 calories * 45 g) / 28 g

x = 257.14 calories

Therefore, a 45 g serving of almonds has 257.14 calories (rounded to two decimal places).

Answer:

angle a: 70°

angle d: 70°

angle dce: 35°

x: 15m

y: 14m

Step-by-step explanation:

all triangles add to 180° so 35 + 75 = 110 and 180-110 = 70

where the two triangles connect and cross, the angles will be the same so it will have the same angle measures as the first triangle which makes the triangles similar

knowing that they are similar triangles will help with figuring out the lengths of the sides.

since they are similar, their sides will be proportional, we just need to figure out the ratio

if we lay the triangles on top of each other, the two 75° angles match up and therefore the sides do too so we can make a fraction 12/18 = 10/x

now we can solve for x

multiply both sides by x

12x/18 = 10

now multiply both sides by 18

12x = 180

divide both sides by 12

x = 15

now we do the same for y

12/18 = y/21

12*21/18 = y

y = 14

Answer:

Step-by-step explanation:

We can start by simplifying the denominator, which is cot(a) + tan(a):

cot(a) + tan(a) = cos(a)/sin(a) + sin(a)/cos(a)

To combine these terms, we can find a common denominator of sin(a)cos(a):

cos^2(a)/(sin(a)cos(a)) + sin^2(a)/(sin(a)cos(a))

= (cos^2(a) + sin^2(a))/(sin(a)cos(a))

= 1/(sin(a)cos(a))

Now we can substitute this expression into the original equation:

sec(a)/(cot(a) + tan(a))

= sec(a) / (1/(sin(a)cos(a)))

= sec(a) * (sin(a)cos(a))

= (1/cos(a)) * (sin(a)/cos(a))

= sin(a)/cos^2(a)

= csc(a)sec(a)

Therefore, the simplified form of sec(a)/(cot(a) + tan(a)) is csc(a)sec(a).

The value of x is given as follows:

x = 3.

Applying the secant-tangent theorem, we have that the following equation holds true:

The weight's height at t=1.5 seconds is roughly 8.07 feet.

a. The equation for simple harmonic motion can be used to find a model that describes the motion of the weight:

Acos(wt + phi) + D = y(t)

A represents amplitude, w represents angular frequency, phi represents phase shift, and D represents vertical shift.

The amplitude A is equal to half the difference between these two heights because we know the weight oscillates between a minimum height of 4 feet and a maximum height of 10 feet:

A = (10 - 4)/2 = 3

The weight completes a full cycle in three seconds, hence the weight's angular frequency is:

T = 2pi/3 and w = 2pi

where T, or the period, denotes the length of time for one complete cycle.

We can set phi to 0 because the weight begins at the lowest height of 4 feet. Last but not least, the vertical shift D is just the average of the highest and lowest heights:

D = (10 + 4)/2 = 7

Combining everything, we obtain:

Y(t) equals 3cos((2pi/3)*t) + 7

b. By simply entering t=1.5 into our model, we can determine the height of the weight at t=1.5 seconds:

3cos((2pi/3)*1.5)*y(1.5) + 7 + 8.07

Hence, the weight's height at t=1.5 seconds is roughly 8.07 feet.

c. We can plot y(t) for t ranging from 0 to 6 seconds in order to graph the model for two periods (two full cycles). The graph is shown here:
