Answer:
g=15.04
Step-by-step explanation:
g=4.7×3.2=15.04
Given
- f(n) values for n=1,2,3,4
- possible candidates for the function
Solution:
Method: Evaluate some of the values, for each function. A function with ANY value not matching the given f(n) values will be rejected.
N=1, f(n)=4
f(1)=4-3(1-1)=4
f(1)=4+3^(1+1)=4+3^2=4+9=13 ≠ 4 [rejected]
f(1)=4(3^(n-1))=4(3^0)=4
f(1)=3(4^(n-1))=3(4^0)=3*1=3 [rejected]
N=2, f(n)=12
f(1)=4-3(2-1)=4-3(1)=1 ≠ 12 [rejected]
[rejected]
f(1)=4(3^(2-1)=4*3^1=4*3=12
[rejected]
Will need to check one more to be sure
N=3, f(n)=3
[rejected]
[rejected]
f(3)=4(3^(n-1))=4(3^(3-1))=4(3^2)=4*9=36 [Good]
[rejected]
Solution: f(n)=4(3^(n-1))
Answer:
As there is one math problem over there.
Lets see the question first:
It says that "A hair dryer is rated 
,if you use the dryer for 
.How much electric energy do you use ?"
Final answer = Electic energy 
Step-by-step explanation:
Electrical Energy 
.
The total amount of electrical energy used depends on the total power used by the electrical device and the total time they are used for.
So we have been given the power of the hair dryer 
Now the time it has been use for 
To calculate electric energy we will multiply both the terms.
Electric energy 
So electric energy used for the hairdryer is =
Step-by-step explanation:
There are infinitely many such integers.
x - y = -6 <em>add y to both sides</em>
x = -6 + y → x = y - 6
1. Choose any y value.
2. Substitute for the equation.
3. Calculate the value of x.
Examples:
for y = 0 → x = 0 - 6 = -6
check: -6 - 0 = -6
for y = 10 → x = 10 - 6 = 4
check: 4 - 10 = -6
for y = -9 → x = -9 - 6 = -15
check: -15 - (-9) = -15 + 9 = -6
