If f(x) is an even function and f(3)=5 then what is the value of 4f(3)+2f(-3)?

Step-by-step explanation:

We have been given that f(x) is an even function and f(3)=5. We are asked to find the value of 4f(3)+2f(-3).

Since we know that graph of an even function is symmetric with respect to y-axis. By the definition of an even function, a function f is even if and only if f(-x)=f(x) for all x in the domain of f.  

Since we have been given that f(x) is an even function, so f(3)=f(-3).

Upon substituting our given values we will get,

Therefore, the value of will be 30.

probability for j is 1/4

while

a is 1/6

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
