F(-10) means the x value in the equation is -10.
Replace x with -10 and solve:
4(-10) -12 = -40 - 12 = -52
F(-10) = -52
A loss of 36 points is -36. A gain of 24 points is +24.
-36 + 24 = -12
This means that there was a loss of twelve points.
Answer
Discount:$59.85
Sales price:$339.15
Multiply$399 by 15% or 0.15 to get the discount of 59.85 and subtract 399 by discount to get sales price.
<span>We have log (3) x = 9. After that Paul wrote: 3 ^x = 9. 3^x = 3^2, x = 2 ( but this is wrong in his firs line ). If we have log˙(x) a = b then: a = x^b, but Paul wrote it in a form: b = x^a. On the other hand, Scott was right. He wrote: 3^9 = x and as a result he had: x = 19,683. Answer: Paul is wrong. Hope I helped! :) Cheers!</span>
Answer:
129.89 m²
Step-by-step explanation:
Area of a circle of radius r is A = πr².
If r = 6.43 m, then A = π(6.43 m)² = 129.89 m²
