Answer:
1. y = -11/4; (-2, -11/4)
2. y = -1; (0, -1)
3. y = -1/8; (1, -1/8)
4. y = 0; (8/7, 0)
5. y = 3/4; (2, 3/4)
Step-by-step explanation:
0.5% or 1/2% of say "x" is 250, whilst "x" is the 100%.
Answer:
14.4 years (about 14 years 6 months)
Step-by-step explanation:
Given data
Principal= $3000
Rate= 4.8%
A. Time= 5 years
The expression for compound interest is
A=P(1+r)^t
Substitute
A= 3000(1+0.048)^5
A= 3000(1.048)^5
A=3000*1.264
A=$3792
Hence the balance will be $3792
B. Final Amount A = $6000
The expression to find time is given ast
t= ln(A/P) / r
substitute
t= ln(6000/3000)/0.048
t= ln2/0.048
t= 0.6931/0.048
t=14.43
Hence the time is 14.4 years (about 14 years 6 months)approx
??? .................. so no question
Answer: 1976
Steps:
Let t* be the year in which the population reached a count of 8920. Solve for t*:
The population grew to the number 8920 in 36 years past 1940, i.e., 1976
