Answer:
-113
Step-by-step explanation:
2a^4+5b^3 --> 2(4)^4+5(-5)^3= -113
not 100% on this since its hard to understand the original equation (I'm assuming that the numbers after the variables are exponents)
Answer:
Step-by-step explanation:
Alexa earns $33,000 in her first year of teaching and earns a 4% increase in each successive year. This means that for each year, her income is 104% of the previous year. So the rate of increase is 104/100 = 1.04. This rate is in geometric progression. The formula for the sum of n terms of a geometric sequence is expressed as
Sn = a(r^n - 1)/r-1
Where
Sn is the nth term
a is the first term
n is the number of terms.
r is the rate or common ratio
From the information given,
a = 33000
r = 1.04
The formula for Alexis total earning over n years will be
Sn = 33000(1.04^n - 1)/(1.04 - 1)
Her earnings for the next 15 years would be
S15 = 33000(1.04^15 - 1)/(1.04 - 1)
S15 = 33000(0.8009) / 0.04
S15 = $668167.50
2 units i believe but not entirely sure
It was in Korea. US Soldiers fought there and gave their lives when the Korean War took place in the early 1950's. In this case, this was a battle between USA against communism, in direct terms and in proxy.
Hope this helps you.
