Answer:

The interest will the borrower pay on is Rs. 1,026 ⇒ answer b

Step-by-step explanation:

* Lets explain how to solve the problem

- A borrower pays 18% interest per year on the first Rs. 600 he borrows

- He pays 17% per year on the loan on the part of the loan in excess

of Rs. 600

- We need to find the interest he will pay on the loan of 6000 for a year

∵ The lone is Rs. 6000 for 1 year

∵ He pays 18% interest for the first Rs. 600

∵ I = Prt , where I is the interest , P is the loan amount , r is the rate

of interest in decimal t is the time

∵ P = 600

∵ r = 18/100 = 0.18

∵ t = 1

∴ I = 600 × 0.18 × 1 = 108

* The interest for the first Rs. 600 is Rs. 108

- The loan is Rs. 6000 , we calculated the interest for the first

Rs. 600, then we want to calculate the interest for the rest of

the loan at rate 17% per year

∵ The rest of the loan = 6000 - 600 = 5400

∵ P = 5400

∵ r = 17/100 = 0.17

∵ t = 1

∴ I = 5400 × 0.17 × 1 = 918

* The interest for the rest of the loan is Rs. 918

- The total interest is the sum of the two interest above

∵ The interest of Rs. 600 is Rs. 108

∵ The interest of the rest of the loan is Rs. 918

∴ The total interest = 918 + 108 = 1026

* The interest will the borrower pay on is Rs. 1,026

Answer:

The measure of the arc CD = 64°

Step-by-step explanation:

It is required to find the measure of the arc CD in degrees.

So, as shown at the graph

BE and AD are are diameters of circle P

And ∠APE is a right angle ⇒ ∠APE = 90°

So, BE⊥AD

And so, ∠BPE = 90° ⇒(1)

But it is given: ∠BPE = (33k-9)° ⇒(2)

From (1) and (2)

∴ 33k - 9 = 90

∴ 33k = 90 + 9 = 99

∴ k = 99/33 = 3

The measure of the arc CD = ∠CPD = 20k + 4

By substitution with k

∴ The measure of the arc CD = 20*3 + 4 = 60 + 4 = 64°

MrRa [10]

Answer:

Step-by-step explanation:

Given;

$f(x)=\frac{e^{2x}}{e^{2x}+3e^x+2}$

substitute $u=e^x\\du=e^x dx\\\\\int\frac{e^{2x}}{e^{2x}+3e^x+2}dx=\int\frac{e^x\dot e^x}{e^x^{2x}+3e^x+2}dx\\\\=\int\frac{udu}{u^2+3u+2}$

Apply partial fraction in (a), we get;

$\frac{u}{u^2+3u+2}=\frac{2}{u+2}-\frac{1}{u+1}\\\\\therefore u^2+3u+2\\=u^2+2u+u+2\\=u(u+2)+1(u+1)\\=(u+2)(u+1)\\\\Now\,\int\frac{u}{u^2+3u+2}\,du=\int\frac{2}{u+2}du-\int\frac{1}{u+1}du\\\\=2ln|u+2|-ln|u+1|+c\\=2ln|e^x+2|-lm|e^x+1|+c$

If JL=18, NK=12, and ML=10, find the perimeter of JKLM A. 42 B. 45 C. 50 D. 56

snow_lady [41]

Answer:

The perimeter of the kite JKLM is 50 units ⇒ C

Step-by-step explanation:

The longest diagonal of the kite is its axis of symmetry which means the longest diagonal divides the kite into two congruent triangles

∵ JKLM is a kite

∵ KM is the longest diagonal

∴ KM is divides the kite into two congruent triangles

∴ Δ JKM is congruent to Δ LKM

∴ JK = LK

∴ JM = ML

∵ ML = 10 units

∴ JM = 10 units

∵ The diagonals of the kite are perpendicular

∴ KM ⊥ JL

∵ KM and JL intersected at N

∴ m∠JNK = 90°

∵ KM is the axis of symmetry of kite JKLM

∴ KM bisects JL at N

∴ JN = NL = $\frac{1}{2}$ JL

∵ JL = 18 units

∴ JN = $\frac{1}{2}$ (18)

∴ JN = 9 units

In Δ JNK

∵ m∠JNK = 90°

∵ JN = 9 units

∵ NK = 12 units

- By using Pythagoras Theorem

∵ (JK)² = (JN)² + (NK)²

∴ (JK)² = (9)² + (12)²

∴ (JK)² = 81 + 144

∴ (JK)² = 225

- Take √ for both sides

∴ JK = 15 units

∵ Jk = LK

∴ Lk = 15 units

∵ The perimeter of the kite is the sum of its 4 sides

∴ P = JK + KL + LM + MJ

∵ JK = LK = 15

∵ JM = ML = 10

∴ P = 15 + 15 + 10 + 10

∴ P = 50

The perimeter of the kite JKLM is 50 units

Find the length of one side of a regular hexagon whose perimeter is 75 feet.

PIT_PIT [208]

Given that the perimeter of a regular hexagon is 75 feet, determine the length of one side.

Given:

Perimeter : 75 ft.

Find:

Side Length:

Work:

Hexagon = 6 six sides

Divide perimeter by amount of sides (6).

75/6 = 12.5

1 side = 12.5 ft

Thus, the length of side on the hexagon is 12.5ft or 12 and 1/2 feet.
