Therefore , the solution of the given problem of equation comes out to be  ratio of y to x is not constant in this situation, y does not directly change with x.

The use of the same variable word in mathematical formulas frequently ensures agreement between two assertions. Mathematical equations, also referred to as assertions, are used to demonstrate expression the equality of many academic figures. Instead of dividing 12 into 2 parts in this instance, the normalise technique adds b + 6 to use the sample of y + 6 instead.

Here,

Checking whether there is a fixed ratio between y and x will help us determine whether y directly changes with x.

In general, straight variation is calculated as follows:

=>  y = kx

where k is the variational constant.

Let's split both sides by x to check if the equation 3y = -7x - 18 can be expressed in this way:

=>  3y/x = -7 - 18/x

Now, 3y/x ought to equal some constant k if the relation between y and x is constant:

=>  3y/x = k

When we add this to the solution we previously determined, we get:

=> k = -7 - 18/x

Since the ratio of y to x is not constant in this situation, y does not directly change with x.

The side length of the unknown segment x in the triangle has a value of 40.1cm

To find the unknown side x, we use the sine rule

The Law of Sines (or Sine Rule) is very useful for solving triangles:

a/sin A = b/sin B = c/sin C

It works for any triangle and it says that:

When we divide side a by the sine of angle A it is equal to side b divided by the sine of angle B, and also equal to side c divided by the sine of angle C

To find the third angle in the triangle, we use the known rule of the sum of angles in a triangle which is equal to 180°

unknown angle = 180° - 90°- 55° = 35°

Using the sine rule let us find the side x

23/sin35 = x/sin90

23/0.5736 = x/1

from here we cross multiply to get

0.5736x = 23

We can find the value of x by dividing both sides by 0.5736

x = 23/0.5736

x = 40.1cm

Hence, the value is 40.1 cm

Function is increasing in the domain of interval (1, ∞).

A quadratic function is a mathematical function of the form:

f(x) = ax² + bx + c

where "a", "b", and "c" are constants, and "x" is the variable.

From the given table of ordered pairs, we can see that the function k is a continuous quadratic function that passes through the points (-1, 0), (0, 2), (2, 5), (3, 4), and (4, 5).

We can estimate the slope of the function between each pair of consecutive points in the table. For example, between (-1, 0) and (0, 2), the slope is positive, so the function is increasing in the interval (-1, 0). Between (0, 2) and (2, 5), the slope is also positive, so the function is increasing in the interval (0, 2). However, between (2, 5) and (3, 4), the slope is negative, so the function is decreasing in the interval (2, 3).

Finally, between (3, 4) and (4, 5), the slope is positive, so the function is increasing in the interval (3, 4). Therefore, the function k is increasing over the intervals (-1, 0) and (3, 4).

(a) Keiko's monthly payment is $536.82. (b) The total amount Keiko will repay is approximately $64,419.19 over the 10-year term. c. (c) The total amount is approximately $14,419.19 in interest.

(a) To find Keiko's monthly payment, we can use the formula for the monthly payment of an amortized loan:

P = (r * A) / (1 - (1+r)^(-n))

where:

P = monthly payment

A = loan amount

r = monthly interest rate (annual interest rate / 12)

n = total number of payments

Plugging in the values we have:

A = $50,000

r = 0.055 / 12

n = 10 * 12 = 120

P = (r * A) / (1 - (1+r)^(-n))

P = (0.055/12 * $50,000) / (1 - (1+0.055/12)^(-120))

P ≈ $536.82

Therefore, Keiko's monthly payment is $536.82.

(b) If Keiko pays the monthly payment each month for the full term of 10 years (120 months), her total amount to repay the loan will be:

Total amount = P * n

Total amount = $536.82 * 120

Total amount ≈ $64,419.19

Therefore, Keiko will repay a total amount of approximately $64,419.19 over the 10-year term.

(c) If Keiko pays the monthly payment each month for the full term of 10 years (120 months), the total amount of interest she will pay can be calculated as:

Total interest = P * n - A

= $536.82 * 120 - $50,000

Total interest ≈ $14,419.19

Therefore, Keiko will pay a total of approximately $14,419.19 in interest over the 10-year term.

The length of the curve y=1/3x³/2-x⁻¹/² from (1, -2/3) to (4, 2/3) is approximately 0.236 units.

what is curve?

In mathematics, a curve refers to a continuous and smooth line or a geometric object that is formed by joining an infinite number of points. Curves can be defined algebraically or geometrically, and they can have different shapes and properties. Some examples of curves include lines, circles, ellipses, parabolas, hyperbolas, and spirals.

Curves are often used in various fields of mathematics, science, and engineering to represent real-world phenomena, such as the trajectory of a moving object, the shape of a surface, or the behavior of a system over time. They are also important in computer graphics and design, where they are used to create visual effects, animations, and models.

In calculus, the study of curves is an essential part of differential and integral calculus. The concepts of limits, derivatives, integrals, and differential equations are used to analyze the properties and behavior of curves, such as their slope, curvature, area, and length.

To find the length of the curve y=1/3x³/2-x¹/² from (1, -2/3) to (4, 2/3), we can use the formula for arc length:

L = ∫[a,b] √(1 + (dy/dx)²) dx

where a and b are the x-coordinates of the starting and ending points of the curve.

First, we need to find the derivative of y:

dy/dx = (d/dx) (1/3 x^³/²- x¹/²) = (1/2) x⁻¹/² - (1/2) x⁻¹/²= x⁻¹/²

Next, we need to find the definite integral of the square root of 1 + (dy/dx)² from 1 to 4:

L = ∫[1,4] √(1 + (x⁽⁻¹/²⁾⁾²) dx

L = ∫[1,4] √(1 + 1/x) dx

To evaluate this integral, we can use the substitution u = 1 + 1/x, which gives du/dx = -1/x²and dx = (1/u) du.

Substituting, we get:

L = ∫[u(1),u(4)] √u (1/u²) du

L = ∫[u(1),u(4)] u⁻¹/² du

L = 2(u(4)¹/²- u(1)¹/²

To find u(1) and u(4), we substitute x=1 and x=4 into the equation for u:

u = 1 + 1/x

u(1) = 2 and u(4) = 1.25

Substituting these values into the expression for L, we get:

L = 2(1.118 - 1)

L = 0.236

Therefore, the length of the curve y=1/3x³/²-x¹/²from (1, -2/3) to (4, 2/3) is approximately 0.236 units.

Answer: To construct a 99% confidence interval for the mean number of books people read, we can use the following formula:

CI = X ± Z*(S/sqrt(n))

where:

X = sample mean (11.3)

S = sample standard deviation (16.6)

n = sample size (1005)

Z = the z-score for the confidence level (99%)

To find the z-score for the 99% confidence level, we can look up the value in a standard normal distribution table or use a calculator. The z-score for a 99% confidence level is 2.576.

Substituting the values into the formula, we get:

CI = 11.3 ± 2.576*(16.6/sqrt(1005))

CI = 11.3 ± 2.576*(0.524)

CI = 11.3 ± 1.35

Therefore, the 99% confidence interval for the mean number of books people read is (9.95, 12.65). We can be 99% confident that the true population mean falls within this interval.

The total feet of steel wire needed to secure the pole is 26 using Pythagoras Theorem.

What is Pythagorean Theorem?

A fundamental idea in mathematics pertains to the lengths of the sides of a right triangle and is known as the Pythagorean theorem. It claims that the hypotenuse's square length, which is the side that faces the right angle, equals the sum of the squares of the lengths of the other two sides of any right triangle. The Pythagorean theorem, which is named after the ancient Greek mathematician Pythagoras who originally proved the theorem, has extensive applications in areas including geometry, trigonometry, and physics.

Let the length of the wire = x.

Using Pythagoras Theorem we have:

x² = 12² + 5²

x² = 144 + 25

x² = 169

x = √(169)

x = 13

Answer:

The value of m that satisfies the equation 6200 = 200^m is approximately 1.94.

Step-by-step explanation:

To find the value of m, we can take the logarithm of both sides of the equation:

log(6200) = log(200^m)

By the laws of logarithms, we can simplify this to:

log(6200) = m log(200)

Now we can solve for m by dividing both sides by log(200):

m = log(6200) / log(200)

Using a calculator, we can evaluate this expression to find:

m ≈ 1.94

Therefore, the value of m that satisfies the equation 6200 = 200^m is approximately 1.94.

We know that the formula for the circumference (C) of a circle is:

C = 2πr

where r is the radius of the circle.

We are given that the circumference is 8πm, so we can write:

8πm = 2πr

Simplifying this equation by dividing both sides by 2π, we get:

r = 4m

Now that we know the radius of the circle, we can use the formula for the area (A) of a circle:

A = πr^2

Substituting the value we found for r, we get:

A = π(4m)^2

Simplifying this equation, we get:

A = π(16m^2)

A = 16πm^2

Therefore, the area of the circle is 16πm^2. The answer is C

We can simplify cosec(t)tant(t) to sec(t). A trigonometric function is a mathematical function that relates the angles of a triangle to the ratios of its sides.

The most common trigonometric functions are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc).

To simplify the expression cosec(t)tant(t), we need to use the trigonometric identity:

cosec(t) = 1/sin(t)

tant(t) = sin(t)/cos(t)

Substituting these expressions into the original expression, we get:

cosec(t)tant(t) = (1/sin(t))(sin(t)/cos(t))

The sin(t) term in the numerator and denominator cancel out, leaving:

cosec(t)tant(t) = 1/cos(t)

Recalling the definition of secant, sec(t) = 1/cos(t), we can express the simplified expression as:

cosec(t)tant(t) = 1/sec(t)

Therefore, we can simplify cosec(t)tant(t) to sec(t).
