What does the 9ft go to ?
Answer:
3,160,080
Step-by-step explanation:
- The first place can be taken by any one of the 22 students.
- The second place can be taken by any one of the remaining 21 students.
- The third place can be taken by any one of the remaining 20 students.
- The fourth place can be taken by any one of the remaining 19 students.
- The fifth place can be taken by any one of the remaining 18 students.
<em>This basically means multiplying 22, 21, 20, 19, and 18. Or, the number of permutation of 22 things taken 5 at a time.</em>
The answer is 22*21*20*19*18 = 3,160,080
<em>Using formula

Step-by-step explanation:
The value of function f(x). =-2ax² -5a + 4 at a = -3 will be -23a + 2.
<h3>What is a function?</h3>
The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.
For example y = sinx , y = x + 3 ets.
Given,
f(x) = - 2ax² -5a + 4
x = -3
f(-3) = - 2a(-3)² -5a + 4
f(-3) = -18a - 5a + 4
f(-3) = 23a + 2
Hence the value of function f(x). =-2ax² -5a + 4 at a = -3 will be -23a + 2.
