invest, to the nearest ten dollars, for the value of the account to reach $7,600 in 7 years?
1 answer:
Answer:
$5,155.7
Step-by-step explanation:
Using the compound interest formula;
Amount = 7600
Time = 7years
Rate = 5.7% = 0.057
Required
Principal
Substitute
A = P(1+r)^n
7600 = P(1+0.057)^7
7600 = P(1.057)^7
7600 = 1.4741P
P = 7600/1.4741
P = 5,155.69
Hence Lilian would need to invest $5,155.7 (to nearest ten dollars)

Sorry idk the answer...
Since you don't know the value of b about the best that you could do is:
(2b)^4
16b^4
16b*b*b*b
9^2 < 6^2 + 8^2
so its acute angled.
#2= +$700 I couldn't see #14 and 15
20% because 75 is the total price and 75 over 15 is 5 and 100 divided by 5 is 20
