Solve the problem if f(x)=int(-4x), find f(-1.8)
Answers
f(-1.8) = int(7.2) = 7
Final answer:
The function f(x) = int(-4x) requires us to find the integer part of the result when x = -1.8. After substituting and simplifying, we find that f(-1.8) = 7.
Explanation:
The problem given is f(x)=int(-4x), and we are asked to find the value of f(-1.8). The int function refers to integer part of a number, which is the number without its decimal component. It's important to note that for negative numbers, the integer part is the number rounded down.
To solve, we first substitute x = -1.8 into the function:
f(-1.8) = int(-4*-1.8) = int(7.2).
The integer part of 7.2 is 7, so f(-1.8)=7.

60% of the jerseys are medium-sized. This is found by dividing the number of medium-sized jerseys (30) by the total number of jerseys (50), getting a result of 0.6, and then multiplying this by 100.
Explanation:
To find out what percent of the jerseys are medium-sized, you would need to divide the number of medium-sized jerseys by the total number of jerseys and then multiply by 100. Here's the calculation step-by-step:
- Divide the number of medium-sized jerseys (30) by the total number of jerseys (50).
- The result of this calculation is 0.6.
- Multiply 0.6 by 100 to get the percentage.
- This gives a result of 60.
So, 60% of the jerseys are medium-sized.
