The value of the derivative of the function g(x) at x = 1 will be 1/3. Then the correct option is A.

A function that may convert into another function is known as an inverse function or anti-function.

If the function is f(x) = sinx + 2x + 1.

Then the derivative of an inverse function g(x) of a function f(x) at a given value (a) will be

\(\rm g'(a) = \dfrac{1}{f'(g(a))}\)

The derivative of f(x) will be

f'(x) = cos x + 2

Then the given value of a will be

a = 1

g(x) = f⁻¹(x)

put x = 0, then we have

f(0) = sin 0 + 2(0) + 1

f(0) = 1

Put x = 1, in the function f⁻¹(x). Then we have

f⁻¹(1) = 0

and

g(1) = 0

Then put a = 1, then we have

\(\rm g'(a) = \dfrac{1}{f'(g(a))}\\\\g'(1) = \dfrac{1}{f'(g(1))}\\\\g'(1) = \dfrac{1}{f'(0)}\\\\g'(1) = \dfrac{1}{\cos 0 + 2}\\\\g'(1) = \dfrac{1}{1+2}= \dfrac{1}{3}\)

Original Cost - $82

First part: Apply the 60% off discount

Convert first the 60% into decimal form

60% ÷ 100% = 0.6

Multiply it to the original cost to determine the discount

$82 ˣ 0.6 = $49.2

Subtract the discount to the original price, to determine the discounted price.

$82 - $49.2 = $32.8

Second part:

The discounted price is now $32.8 for which we will apply another 10% discount.

Again, convert 10% into decimal

10% ÷ 100% = 0.1

Multiply it to the discounted price, to determine the second discount.

$32.8 ˣ 0.1 = $3.28

Subtract the discount to the already discounted price.

$32.8 - $3.28 = $29.52

Therefore, the final sale price of the watch is at $29.52.

Each campsite will receive 7.8 liters of water.

If the campers collect water from a stream and share it equally among 8 campsites, we need to determine how much water each campsite receives.

The total amount of water collected is given as 62.4 liters in a bucket. To find the amount of water per campsite, we divide the total amount of water by the number of campsites.

Dividing 62.4 liters by 8 campsites gives us 7.8 liters per campsite.

It's important to note that this calculation assumes an equal distribution of water among all the campsites. However, in practical situations, the division may not be exact due to factors such as spillage, uneven pouring, or variations in the bucket's actual capacity.

Answer:

C

Step-by-step explanation:

Hope I was able to help!! :)

The IS relation is given by: Y = (intercept value rounded to two decimal places) + (slope value rounded to two decimal places) in the numerical example of the IS-LM model.

To derive the IS relation, we need to equate aggregate demand (AD) to aggregate supply (AS). Aggregate demand consists of consumption (C), investment (I), government spending (G), and net exports (NX). In this case, we assume net exports to be zero.

Given:

C = 233 + 0.47YD

I = 143 + 0.22Y - 1,094i

G = 299

T = 239

Aggregate demand (AD) = C + I + G

Substituting the given equations into AD:

AD = (233 + 0.47YD) + (143 + 0.22Y - 1,094i) + 299

Simplifying:

AD = 233 + 143 + 299 + 0.47YD + 0.22Y - 1,094i

Combining like terms:

AD = 675 + 0.47YD + 0.22Y - 1,094i

Since we want an equation with Y on the left side, we need to express YD in terms of Y by substituting YD = Y - T.

AD = 675 + 0.47(Y - T) + 0.22Y - 1,094i

AD = 675 + 0.47Y - 0.47T + 0.22Y - 1,094i

Combining like terms again:

AD = (0.47Y + 0.22Y) + (675 - 0.47T - 1,094i)

AD = 0.69Y - 0.47T - 1,094i + 675

Comparing with the IS relation Y = a + bAD, we have:

Y = 0.69Y - 0.47T - 1,094i + 675

Rearranging terms to have Y on the left side:

Y - 0.69Y = -0.47T - 1,094i + 675

0.31Y = -0.47T - 1,094i + 675

Dividing both sides by 0.31:

Y = (-0.47T - 1,094i + 675) / 0.31

Now, we can calculate the intercept and slope terms:

Intercept term = (-0.47T - 1,094i + 675) / 0.31

Slope term = 1 / 0.31

Rounding these values to two decimal places, the IS relation is:

Y = Intercept term + Slope term = (intercept value rounded to two decimal places) + (slope value rounded to two decimal places).

Break it up into two trapezoids as shown

area = trap1 + trap2

      = 2 *   (7+3) / 2   + 3 *  ( 7 + 3) / 2 = 10 + 15 = 25 units^2

To determine the magnitude of the resultant force acting on the object, we can use the Pythagorean theorem.

Let's denote the magnitude of the first force as F₁ = 100 N and the magnitude of the second force as F₂ = 150 N. Since the forces act at 90° to each other, they form a right triangle.

According to the Pythagorean theorem, the magnitude of the resultant force (F) is given by:

\(F = \sqrt{F_1^2 + F_2^2}\)

Substituting the given values:

\(F = \sqrt{100^2 + 150^2} \\\\= \sqrt{10000 + 22500} \\\\= \sqrt{32500} \\\\\approx 180.28 \, \text{N}\)

Therefore, the magnitude of the resultant force acting on the object is approximately 180.28 N, which corresponds to option b.

The value of x is 10.

Given triangle is a right-angled triangle.

Let the lengths of not mentioned lengths be 2p(hypotenuse) and 2q (other side).

There are two triangles in the given picture.

Consider the smaller triangle.

Apply Pythagoras theorem to that i.e.,

\(p^{2}\) = \((3x)^{2} + q^{2}\)

(Here, total hypotenuse is 2p length and the smaller triangle has half of its length. So, length is p. Similarly in case of q)

\(p^{2} = 9x^{2} + q^{2}\)  (Equation 1)

Now, consider the large triangle.

Apply Pythagoras theorem to that i.e.,

\((2p)^{2} = (4x + 20)^{2} + (2q)^{2}\)

\(4p^{2} = (16x^{2} + 160x + 400) + 4q^{2}\)

Substitute \(p^{2}\) from Equation 1

\(4(9x^{2} + q^{2} ) = 16x^{2} + 160x + 400 + 4q^{2}\\\)

\(36x^{2} + 4q^{2} = 16x^{2} + 160x + 400 + 4q^{2}\)

\(36x^{2} = 16x^{2} + 160x + 400\)  (\(4q^{2}\) from both sides got cancelled)

\(20x^{2} - 160x - 400 = 0\)

Solving the quadratic equation,

\(20x^{2} - 200x + 40x - 400 = 0\)

\(20x(x - 10) + 40(x - 10) = 0\)

\((20x+ 40)(x - 10) = 0\)

So, 20x + 40 = 0 or x - 10 = 0

i.e., x = -2 or 1o

But \(x \neq -2\) because angles cannot be negative.

So, x is 10.
