The cyclist will pedal at given speed for minimum 1.25 and maximum 2.25 hours.

The relation between speed, distance and time is as follows -

Speed = distance ÷ time. The maximum and minimum number of hours will depend on the distance. The maximum number of hours will be spent when maximum distance is covered, and minimum number of hours will be spent when minimum distance is covered.

Maximum distance = 35 + 10

Maximum distance = 45 miles

Minimum distance = 35 - 10

Minimum distance = 25 miles

Maximum number of hours = 45 ÷ 20

Maximum number of hours = 2.25 hours

Minimum number of hours = 25 ÷ 20

Minimum number of hours = 1.25 hours

Thus, cyclist will pedal at given speed for minimum 1.25 and maximum 2.25 hours.

Given question is not having enough information, so I am attaching the complete question below:

The least common denominator (LCD) for the rational expressions A and B is (x - 2)(x + 2).

To find the least common denominator (LCD) of rational expressions, you can follow these steps:

Identify the denominators of the rational expressions involved.

Factorize each denominator completely.

Identify the common factors among all the denominators. Include each factor the maximum number of times it appears in any of the denominators.

Multiply together all the common factors identified in step 3. This product represents the LCD.

Simplify the LCD if possible by canceling out any common factors that appear in both the numerator and denominator of any rational expression.

Here's an example to illustrate the process:

Consider the rational expressions:

A = (3x) / (x² - 4)

B = (2) / (x - 2)

Step 1: Identify the denominators

Denominator of A: x² - 4

Denominator of B: x - 2

Step 2: Factorize each denominator

x² - 4 = (x - 2)(x + 2)

Step 3: Identify the common factors

The common factor is (x - 2).

Step 4: Multiply together the common factors

LCD = (x - 2)(x + 2)

Step 5: Simplify the LCD

In this case, the LCD is already in its simplest form.

So, the least common denominator (LCD) for the rational expressions A and B is (x - 2)(x + 2).

The brokerage charge he has to pay will be $1,659.45.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.

Given, A first-time homebuyer is financing a house for $128,900.

The brokerage charge = 300 + 1.05% of house charge

The brokerage charge = 300 + 1.05% of 128,900

The brokerage charge = 300 + 1.05/100 * 128,900

Factorisation of a polynomial is the decomposition of a polynomial into smaller polynomials.

Thus, the polynomial that is factored in completely is the polynomial that can not be decomposed again.

Now,

g⁵ - g = g(g⁴ - 1) (it can be factored)

4g³ + 18g² + 20g = 2g(g + 2)(2g + 5)

Therefore, the integral evaluates to sin(t) + C, where C is the constant of integration.

Dividing both sides by (1 - v²), we get:

u² = v² / (1 - v²)

Taking the square root, we have:

Since v = u/√(1 + u²), we substitute this expression into the equation to solve for u:

u = √((u/√(1 + u²))² / (1 - (u/√(1 + u²))²))

Simplifying, we have:

u = √(u² / (1 + u²) / (1 - u² / (1 + u²)))

= u / √(1 + u^2)

Since u = sin(t), we have:

sin(t) = u / √(1 + u²)

Multiplying both sides by √(1 + u²), we get:

√(1 + u²)sin(t) = u

Using the original substitution u = sin(t), we have:

√(1 + sin²(t))sin(t) = sin(t)

Therefore, v = sin(t).

Going back to the integral ∫(1/√(1 + u²)) du = v + C, we have:

The standard cell potential Ecell∘ for the equation Fe(s) + F₂(g) ⟶ Fe²⁺(aq) + 2F⁻(aq) is 2.87 V.

To calculate the standard cell potential (Ecell∘), we need to use the standard reduction potentials (E°) for the half-reactions involved in the cell. The reduction potential for the reduction half-reaction of Fe²⁺(aq) + 2e⁻ ⟶ Fe(s) is given as +0.44 V (taken from the standard reduction potentials table). The oxidation half-reaction of F₂(g) ⟶ 2F⁻(aq) + 2e⁻ has a reduction potential of +2.87 V.

To find the overall cell potential, we subtract the reduction potential of the anode (F₂) from the reduction potential of the cathode (Fe²⁺/Fe):

Ecell∘ = Ered(cathode) - Ered(anode)

Ecell∘ = (+0.44 V) - (+2.87 V)

Ecell∘ = -2.43 V

Answer:

Approximately \(30\; \rm N\) toward the center of the object.

Step-by-step explanation:

Look up the gravitational constant and the mass of the earth:

\(\begin{aligned}G &\approx 6.67 \times 10^{-11}\; \rm m^{3} \cdot kg^{-1} \cdot s^{-2} \\ &= 6.67 \times 10^{-11} \; \rm N \cdot m^{2} \cdot kg^{-2}\end{aligned}\).

\(M \approx 5.97 \times 10^{24}\; \rm kg\).

Convert the unit of distance to standard units:

\(\begin{aligned}r &= 25600\; \rm km \\ &= (25600 \times 10^{3})\; \rm m \\ &= 2.56 \times 10^{7}\; \rm m\end{aligned}\).

Consider two spherical objects with mass \(m_{1}\) and \(m_{2}\). Let \(r\) denote the distance between the centers of the two objects. By Newton's Law of Universal Gravitation, the size of the gravitational force between these two objects would be:

\(\begin{aligned}F &= \frac{G \cdot m_{1} \cdot m_{2}}{r^{2}}\end{aligned}\).

Thus, the size of the gravitational force between this object and the earth would be:

\(\begin{aligned}F &= \frac{G \cdot m \cdot M}{r^{2}} \\ &\approx \frac{1}{2.56\times 10^{7}\; \rm m} \\ &\quad \times 6.67 \times 10^{-11}\; \rm N \cdot m^{2}\cdot kg^{-2} \\ &\quad \times 50\; \rm kg \times 5.97 \times 10^{24}\; \rm kg \\ &\approx 30\; \rm N\end{aligned}\).

Since gravitational force is attractive, the \(50\; \rm kg\) object in this question would attract the earth through the gravitational force. Thus, this force would point towards the center of this \(50\; \rm kg\!\) object.

Answer:

-2 is the answer

Step-by-step explanation:

y=mx+b

b= y intercept

because it is a negative it replaces the addition sign so that it is not a positive 2.

Since x > 0, the tangent of f'(x) is always positive, and the denominator is always positive. Therefore, f'(x) is always positive, which means that f(x) is always increasing and can only cross the x-axis once. Hence, f(x) has only one root on its entire domain.

To find the y-intercept of line L, we need to determine the equation of line L.

Since line L is tangent to the graph of y = ex at the point (k, ek), the slope of line L must be equal to the slope of the tangent line to y = ex at (k, ek), which is simply ek.

Therefore, the equation of line L is:

y - ek = ek(x - k)

Simplifying, we get:

y = ekx - ek2

To find the y-intercept, we set x = 0 and solve for y:

y = ek(0) - ek2 = -ek2

Therefore, the y-intercept of line L is -ek2.

We need to find the value of k such that the y-intercept of line L is 1/2.

-ek2 = 1/2

Solving for k, we get:

k = ln(sqrt(2))

So the answer is (A) 0.405.

To prove that the function has only one root on its entire domain, we take the derivative of f(x) and show that it is always positive.

f(x) = ln(x) - 1/x

f'(x) = 1/x + 1/x^2 = (x+1)/x^2
