Evaluate the following:<br><br> Options are:<br> pi/2<br> pi/8<br> pi<br> Does not converge
andreev551 [17]

Answer:

π/8

Step-by-step explanation:

∫₂°° dx / (4 + x²)

If x = 2 tan u, then dx = 2 sec²u du.

When u = π/4, x = 2.  As u approaches π/2, x approaches ∞.

∫ (2 sec²u du) / (4 + 4 tan²u)

½ ∫ (sec²u du) / (1 + tan²u)

½ ∫ (sec²u du) / sec²u

½ ∫ du

½ (π/2 − π/4)

π/8

A shoe dealer purchased net Birr 8,000 worth of shoes from a shoe company.A Find the amount it is to pay the company including V
Yanka [14]

Answer:

A) Total amount to be paid = Birr 8,560

B) Amount of VAT liable to the dealer = Birr 520

Step-by-step explanation:

The tax on bought commodity and the tax on sold commodity isn't provided but in some places, these values are 7% and 9% respectively. So, these are the values that will be used for this question.

Note that these values vary from country to country and the value missing from this question will not change how the question is solved; the question will still be solved in a similar manner, only the parameters will vary.

A) The dealer bought Birr 8000 at 7% tax.

Total amount to be paid = cost price (1 + r%)

r = 7% = 0.07

Total amount to be paid = 8000 × 1.07 = Birr 8,560

B) To find the VAT, it is the difference between the tax paid when the good was bought and the tax put on it after it was sold.

Tax paid when the shoes were bought = 7% of cost price = 7% × 8,000 = Birr 560

Tax paid when the shoes were sold = 9% of selling price = 9% × 12,000 = Birr 1,080

VAT = tax recovered on sale - Tax paid on purchase

VAT = 1080 - 560 = Birr 520

Hope this Helps!!!

A ball is thrown into the air with an upward velocity of 48 ft/s. Its height h in feet after
Paladinen [302]

Answer:

Step-by-step explanation:

The equation used to represent the height of the ball, h in feet after t seconds is expressed as

h = -16t² + 48t + 8

The equation is a quadratic equation. The plot of this equation on a graph would form a parabola whose vertex would be equal to the maximum height travelled by the ball.

The vertex of the parabola is calculated as follows,

Vertex = -b/2a

From the equation,

a = -16

b = 48

Therefore,

Vertex = - 48/2 × - 16 = 48/32 = 1.5 seconds

So the ball will attain maximum height in 1.5 seconds.

To determine the maximum height, we would substitute t = 1.5 into the given equation. It becomes

h = -16(1.5)² + 48(1.5) + 8

h = - 36 + 72 + 8 = 44 feet

Find the area of a regular pentagon with an apothem of 11 units. *
docker41 [41]

Answer:

<h2>440 square units</h2>

Step-by-step explanation:

We can find half of a side of the pentagon with the expression

tan(36\°)=\frac{s_{half} }{11}

Because, as a regular polygon, all its sectors have the same central angle, and the apothem divides equally each sector in two equal parts.

s_{half} \approx 8

Therefore, half of a side is 8 units long, which means each side measures 16 units.

Now, the area of a penthagon is defined by

A=\frac{p \times a}{2}

Where p is the perimeter and a is the apothem. Where the perimeter is the sum of all sides, which is 80 units.

A= \frac{80 \times 11}{2} =440 \ u^{2}

Therefore, the right answer is the second choice.
