Answer: The mass of the remaining element = 1.1 grams .

Step-by-step explanation:

Exponential equation of decay: [tex]y=A(1-r)^x[/tex] ...(i), where A = intial value , r= rate of decay in decimal , x= time.

As per given :

Initial mass : A= 140 grams

Rate of decay : r= 21.6% per minute= 0.216 per minute.

x= 20  minutes

Substitute values in (i) , we get

[tex]y=140(1-0.216)^20\\\\=140(0.784)^2^0=1.077579422[/tex]

Hence, the mass of the remaining element = 1.1 grams .

Answer:

Step-by-step explanation:

If [tex]\sum _{n=1}^{\infty }\:\frac{6}{3^n}=3[/tex] then, The truncation error for S4  is equal to 0.037.

We have given that,

[tex]\sum _{n=1}^{\infty }\:\frac{6}{3^n}=3[/tex]

We have to determine the value of S_4

Here plug the value n=4.

A series is the sum of a sequence. In other words, a series is just the addition of all the terms in a sequence.

Therefore we get,

[tex]\sum _{n=1}^{\infty }\:\frac{6}{3^4}=3[/tex]

Therefore the value of S_4=0.037

Answer:

the answer is the question with $580 in it please correct me if im wrong

Step-by-step explanation:

Jean can expect to earn about $580 on her investment of $4,250 if she invests in FLMD.

The expected return on SOLR is calculated by multiplying the probability of each outcome by the amount of the gain or loss, and then adding these results:

50% chance of $1,000 gain: 0.5 x $1,000 = $500

35% chance of $200 gain: 0.35 x $200 = $70

15% chance of $600 loss: 0.15 x -$600 = -$90

Therefore, the expected return on SOLR is $500 + $70 - $90 = $480.

The expected return on FLMD is calculated in the same way:

80% chance of $750 gain: 0.8 x $750 = $600

20% chance of $100 loss: 0.2 x -$100 = -$20

Therefore, the expected return on FLMD is $600 - $20 = $580.

Since the expected return on FLMD is higher than the expected return on SOLR, FLMD is the better investment.

The expected return on FLMD is $580, which means that Jean can expect to earn about $580 on her investment of $4,250 if she invests in FLMD.

Answer:

x = 45

Step-by-step explanation:

The angles are supplementary

(2x + 40) + (3x - 85) = 180

Combine like terms

5x - 45 = 180

Add 45 to both sides

5x = 225

Divide both sides by 5

x = 45
