A certain business has implemented a new incentive plan whereby employees earn tokens for every sale they make.
1 answer:
For the answer to the question above,
Suppose that for x sales the number of tokens the employee earns is:
<span>ax^3 + bx^2 + cx + d </span>
<span>Therefore: </span>
<span>a(1^3) + b(1^2) + c(1) + d = 1 </span>
<span>a(2^3) + b(2^2) + c(2) + d = 6 </span>
<span>a(3^3) + b(3^2) + c(3) + d = 12 </span>
<span>a(4^3) + b(4^2) + c(4) + d = 19 </span>
<span>Therefore: </span>
<span>a + b + c + d = 1 </span>
<span>8a + 4b + 2c + d = 6 </span>
<span>27a + 9b + 3c + d = 12 </span>
<span>64a + 16b + 4c + d = 19 </span>
<span>Solve that to get: </span>
<span>a = 0 </span>
<span>b = 1/2 </span>
<span>c = 7/2 </span>
<span>d = -3 </span>
<span>Therefore, the formula is: </span>
<span>(1/2)x^2 + (7/2)x - 3 </span>

First, move 9x^2 to the right:
7y^2 = 42 - 9x^2
Then, divide 7 on both sides:
y^2 = 6 - 9/7 * x^2
Add 2.38 and 4.89 then subtract 3 giving you 4.27
Answer:
The true statement is that the answer is 75
Step-by-step explanation:
<span>the tens digit = n
</span><span>the units digit = n-5
n + n-5 = 9
2n = 9+5
2n = 14
n = 7 </span>← the tens digit
the units digit = n-5 = 7 - 5 = 2
<span>the number is 72</span>
The correct answer is the fourth one
