as answered in the attached file.
Explanation:
The detailed steps, derivation and appropriate differentiation is as shown in the attachment
Answer:
a. $79,122.50
b. 314. 84 miles.
c. 700 ways.
Explanation:
a. Compound interest = A = P (1 + r/n)nt ;
where P = 7500 (principal amount)
r = 15% (interest rate)
t = 16 (no of years)
n = 4 (no of times compounded annually.)
and finally A is the Amount (present value after 16 years)
Upon calculation A = $79,122.50.
b. Answer: 314. 84 miles.
Explanation:
Given data. 160 miles / 7.75 liters of gasoline
Therefore 1 liter of gasoline = 160/7.75 = 20.645 miles/ liter.
15.25 liters of gasoline = 20.645 * 15.25 = 314.84 miles.
c. Answer: 700 ways.
Explanation:
This is an application of generalized principle of counting.
4 Americans can be choosen from 7 Americans = 7C4 = 35
3 Russians can be choosen from 6 Russians = 6C3 = 20.
Total number of ways = (7C4)* (6C3) = 35 * 20 = 700 ways.
Given data:
•) applied voltage = 15 V
•). Resistance = 1000 ohm
Required:
•). The magnitude of current= ?
•••••••••••••SOLUTION•••••••••••••
We can find the relation ship between current, voltage and resistance with the help of Ohms law.
According to ohms law;
V= IR.
Rearranging the above equation;
I= V/ R
Putt the values in the above equation; we get
I= 15V/ 1000ohm
I = 0.015 A( ampere)
••••••••••••••• CONCLUSION•••••••
The value of the current would be 0.15 ampere when Resistance is equal to 1000 and that of Voltage is equal to 15 V.
Answer:
The appropriate response is "Concatenation". A further explanation is given below.
Explanation:
- Two or much more strings are almost always concatenated besides space-saving purposes, and therefore could be acknowledged as either a single product.
- A straightforward example that demonstrates concatenation should be to figure out what it means. How and why that ends up making a term separate from several other phrases is that almost all the messages are stacked together without any open space between each one.
