Answer»

♣ Qᴜᴇꜱᴛɪᴏɴ :

During the spring of 2020, the state of Indiana was on lock down ORDERS due to COVID-19. The state's business sales dropped exponentially and are modeled after the following equation:

Sales = 500 (1 - 0.10)^t

where t = number of days and sales = number of millions of dollars.

When sales have reached $23.5 million, it will be DECLARED a STATEWIDE economic crisis. How many days until sales reach the economic crisis?

★═════════════════★

♣ ᴀɴꜱᴡᴇʀ :

It will take 29 days to declare economic crisis

★═════════════════★

♣ ᴄᴀʟᴄᴜʟᴀᴛɪᴏɴꜱ :

According To Question :

Sales = 500 (1 - 0.10)^t

where t = number of days and sales = number of millions of dollars.

i. Compare it with a model

y = a(1 - b)ˣ

where b is percent change

Hence we get :

b = 0.10 = 10%

$\large\boxed{\sf{b=10\:\%}}$

ii. What will be the sales after two weeks (14 days) ?

Sales

= 500 (1 - 0.10)¹⁴

= 500 × (0.90)¹⁴

= 500 × 0.228

= 114 million dollars

$\large\boxed{\sf{Sales=\$114\:million}}$

iii. If sales = $23.5 million , then declare economic crisis

23.5 = 500 (1 - 0.10)^t

Diving both sides by 500 :

23.5/500 = (500 (1 - 0.10)^t)/500

0.047 = (1 - 0.10)^t

0.047 = (0.90)^t

In(0.047) = In(0.90)^t

-3.057 = t In(0.90)

-3.057 = t × (-0.105)

t = 3.057/0.105

t = 29.11

$\large\boxed{\sf{t\approx29\:days}}$

Hence it will take 29 days to declare economic crisis

$\huge{\underline{\underline{\sf{\orange{Question:-}}}}}$

In ∆ABC it is given that ∠A=70°,∠B=52° ,BO and CO are are the BISECTOR of ∠B and ∠C respectively ,find ∠OCD and ∠BOC.

━━━━━━━━━━━━━━━━━━━━━━━━━

$\huge{\underline{\underline{\sf{\orange{Solution:-}}}}}$

We have that the SUM of the ANGLES of a triangle is 180°.

$\therefore \: \angle \: A + \angle \: B + \angle \: C = 180\degree$

$⇒ 70\degree + 52\degree + \angle \: C = 180\degree \\$

$⇒ \angle \: C = (180\degree - 122\degree) = 58\degree \\$

$\therefore \: \angle \: OCB = \frac{1}{2} \angle \: C = ( \frac{1}{2} \times 58\degree) = 29\degree \\$

$and \: \angle \: OBC = \frac{1}{2} \angle \: B = ( \frac{1}{2} \times 52\degree) = 26\degree \\$

In ∆BOC,we have

$\angle \: OBC + \angle \: OCB + \angle \: BOC = 180\degree \\$

$⇒ 26\degree + 29\degree + \angle \: BOC = 180\degree \\$

$⇒ \angle \: BOC = (180\degree - 55\degree) = 125\degree \\$

$hence, \: \angle \: OCB = 29\degree \: and \: \angle \: BOC = 125\degree \\$

Let the first function = f1(x) = f(x) and the second function = g1(x) = ex. Therefore,I1 = f(x) ∫ ex dx – ∫ [df(x)/dx ∫ ex dx] dx Or, I1 = ex f(x) – ∫ ex f ’(x) dx + C Substituting the value of I1 in equation (1), we get I = ex f(x) – ∫ ex f ’(x) dx + ∫ ex f ’(x) dx + C = ex f(x) + C Thus, ∫ ex [f(x) + f ’(x)] dx = ex f(x) + C … (2)

√ ex(f(x) + f'(x) ) dx =

Answer»

Answer:

To BEGIN with, let’s say

I = ∫ ex [f(X) + f ’(x)] DX

Opening the brackets, we get,

I = ∫ ex f(x) dx + ∫ ex f ’(x) dx = I1 + ∫ ex f ’(x) dx … (1)

Where, I1 = ∫ ex f(x) dx

To solve I1, we will use INTEGRATION by PARTS. Let the first function = f1(x) = f(x) and the second function = g1(x) = ex. Therefore,I1 = f(x) ∫ ex dx – ∫ [df(x)/dx ∫ ex dx] dx

Or, I1 = ex f(x) – ∫ ex f ’(x) dx + C

Substituting the value of I1 in equation (1), we get

I = ex f(x) – ∫ ex f ’(x) dx + ∫ ex f ’(x) dx + C = ex f(x) + C

Thus, ∫ ex [f(x) + f ’(x)] dx = ex f(x) + C … (2)
