Answer:
-197.2
Step-by-step explanation:
Since it is arithmetic series, first find the difference d between the two know series.
3.8 - 6 = - 2.2
d = -2.2
a = 6
Tn = -29.2
Looking for the n term, use the linear method.
Tn = a+( n - 1)d
Substitute all the parameters
-29.2 = 6+( n - 1 ) -2.2
-29.2 = 6 - 2.2n + 2.2
- 29.2 = 8.2 - 2.2n
-29.2 - 8.2 = - 2.2n
-37.4 = -2.2n
n = 37.4/ 2.2
n = 17 terms.
To Find the exact sum of the arithmetic series, use the sum formula below
Sm = n/2( 2a + (n - 1)d)
Sm = 17/2( 2 × 6 + ( 17 - 1 ) -2.2
Sm = 17/2(12 - 35.2)
Sm = 8.5( - 23.2)
Sm = - 197.2
Therefore, the exact sum of the arithmetic series is -197.2
Answer:
I do not know what the rest of the problem is so I can not answer
Answer:
Step-by-step explanation:
<u>If I got it right, we have:</u>
- Formula Pf = P0*e^(rt)
- Pf = 75709
- P0 = 1349
- r = 25% = 0.25
- t = ?
<u>Substitute the given values and solve for t:</u>
- 75709 = 1349*e^(0.25t)
- e^(0.25t) = 75709/1349
- e^(0.25t) = 56.1223
- ln e^(0.25t) = ln 56.1223
- 0.25t = 4.03
- t = 4.03/0.25
- t = 16.12 hr
Answer:
the correct answer is option ( C )
