Answer:
a(87) = -590
Step-by-step explanation:
Notice how each term of this arithmetic sequence is equal to the sum of the previous term and the common difference, -12.
The general formula a(n) = a(1) + (n - 1)d becomes:
a(n) = 12 - 7(n - 1)
and the 87th term a(87) = 12 - 7(87 - 1), or
a(87) = 12 - 7(86)
a(87) = -590
<h3><u>The expression gives the number of transistors in a dense integrated circuit in 1979 is:</u></h3>
<em><u>Solution:</u></em>
<em><u>The increasing function is given as:</u></em>
Where,
y is the future value
a is the initial value
r is the growth rate
t is the number of years
From given,
a = 5000
t = 1974 to 1979 = 5 years
<em><u>Substituting the values in formula,</u></em>
Thus the expression gives the number of transistors in a dense integrated circuit in 1979 is found
Answer:
I think this is a high school problem in in 5th grade TnT
Answer:
The interest rate is 10%.
Step-by-step explanation:
Interest = principal * rate * time
time is always in years. 6 month = 0.5 year
1.) 165 = 3300 * r * 0.5
2.) multiply 0.5 and 3300
165 = 1650r
3.) divde 1650 to each side
0.1 = r
0.1 = 10%
