For A, you take 70% of 421,000 and subtract that from 421,000. You should solve like this: 421,000 - (0.7 x 421,000).

For B, you take 40% of 31.50 and add it to 31.50. (31.50 + (31.50 x 0.4).

This is all I can give for now. Glad to help you!

Answer:

A) Bacteria left after taking the new drug = 126,300 bacteria

B) The new cost is $44.10

C) the has to produce 181,819 drug to make $2 million profit.

Step-by-step explanation:

Given:

New drug eliminate 70% of bacteria. If there are over 100,000 bacteria after the new drug the patient has to take another drug which cost 40% more expense.

<u>Part A</u>

A new patient has 421,000 bacteria.

The new drug eliminate 70% of the bacteria.

Eliminated bacteria = 70% of 421,000

= \frac{70}{100} *421,000\\=0.7*421,000\\= 294,700

Bacteria left after taking the new drug = 421,000 - 294,700

Bacteria left after taking the new drug = 126,300 bacteria

<u>Part B</u>

The new cost 40% more than $31.50

New cost = $31.50 + 40% of 31.50

= = 31.50 + 0.4*31.50\\= 31.50 + 21.60\\= $44.10

The new cost is $44.10

<u>Part C</u>

The company produces them with $11 profit.

The company has to make $2,000,000 profit.

The number of drug produce = $2,000,000 divided by $11

= \frac{2000000}{11} = 181,818.18

The drug cannot be in decimal form.

So, the company has to produce 181,819 drug to make $2 million profit.

<u>Answer:</u>

  • $2,800 = Principle + Interest

<u>Step-by-step explanation:</u>

Using PRT/100, let's find the interest.

  • => 2,000 x 8 x 5/100
  • => 20 x 8 x 5
  • => $800

<u>Conclusion: </u>

Therefore, the interest plus principle is 2,000 + 800, which is $2,800.

Hoped this helped.

Find all possible values of α+
const2013 [10]

Answer:

\rm\displaystyle  0,\pm\pi

Step-by-step explanation:

please note that to find but α+β+γ in other words the sum of α,β and γ not α,β and γ individually so it's not an equation

===========================

we want to find all possible values of α+β+γ when <u>tanα+tanβ+tanγ = tanαtanβtanγ</u><u> </u>to do so we can use algebra and trigonometric skills first

cancel tanγ from both sides which yields:

\rm\displaystyle  \tan( \alpha )  +  \tan( \beta ) =  \tan( \alpha )  \tan( \beta )  \tan( \gamma )  -  \tan( \gamma )

factor out tanγ:

\rm\displaystyle  \tan( \alpha )  +  \tan( \beta ) =   \tan( \gamma ) (\tan( \alpha )  \tan( \beta ) -  1)

divide both sides by tanαtanβ-1 and that yields:

\rm\displaystyle   \tan( \gamma ) =  \frac{ \tan( \alpha )  +  \tan( \beta ) }{ \tan( \alpha )  \tan( \beta )    - 1}

multiply both numerator and denominator by-1 which yields:

\rm\displaystyle   \tan( \gamma ) =   -  \bigg(\frac{ \tan( \alpha )  +  \tan( \beta ) }{ 1 - \tan( \alpha )  \tan( \beta )   } \bigg)

recall angle sum indentity of tan:

\rm\displaystyle   \tan( \gamma ) =   -  \tan( \alpha  +  \beta )

let α+β be t and transform:

\rm\displaystyle   \tan( \gamma ) =   -  \tan( t)

remember that tan(t)=tan(t±kπ) so

\rm\displaystyle   \tan( \gamma ) =    -\tan(   \alpha   +\beta\pm k\pi )

therefore <u>when</u><u> </u><u>k </u><u>is </u><u>1</u> we obtain:

\rm\displaystyle   \tan( \gamma ) =    -\tan(   \alpha   +\beta\pm \pi )

remember Opposite Angle identity of tan function i.e -tan(x)=tan(-x) thus

\rm\displaystyle   \tan( \gamma ) =    \tan(   -\alpha  -\beta\pm \pi )

recall that if we have common trigonometric function in both sides then the angle must equal which yields:

\rm\displaystyle  \gamma  =      -   \alpha   -  \beta \pm \pi

isolate -α-β to left hand side and change its sign:

\rm\displaystyle \alpha  +  \beta  +   \gamma  =  \boxed{ \pm \pi  }

<u>when</u><u> </u><u>i</u><u>s</u><u> </u><u>0</u>:

\rm\displaystyle   \tan( \gamma ) =    -\tan(   \alpha   +\beta \pm 0 )

likewise by Opposite Angle Identity we obtain:

\rm\displaystyle   \tan( \gamma ) =    \tan(   -\alpha   -\beta\pm 0 )

recall that if we have common trigonometric function in both sides then the angle must equal therefore:

\rm\displaystyle  \gamma  =      -   \alpha   -  \beta \pm 0

isolate -α-β to left hand side and change its sign:

\rm\displaystyle \alpha  +  \beta  +   \gamma  =  \boxed{ 0  }

and we're done!

Determine the nth term for each of the following sequences:16,15,14,13,12,..
Vladimir79 [104]
F(n) = 1st term - common difference (n - 1)

The operation is subtraction because the sequence is decreasing.

n = number of the term you are looking for
1st term = 1st number in the sequence, in this case, 16
common difference = difference between one number to the next

f(n) = 16 - 1(n-1)

Assuming we are looking for the 5th term.
f(5) = 16 - 1(5-1)
       = 16 - 1(4)
       = 16 - 4
       = 12     * as you can see, 12 is the 5th term of the sequence.

If you are looking for the equivalent of the nth term, simply substitute n by the number you are looking for and solve the equation.

Hi there

dollar amount of each monthly payment is interest
11,798.81÷120
=98.32

percent of the total payments is total interest
(11,798.81÷41,798.81)×100
=28.23%

Hope it helps
