Which of the following is a function equivalent to f(x) = 5(1.9)^3x? f(x) = 34.29^x
f(x) = 5(6.86x)
f(x) = 5(6.86)^x
f(x) = 328.51^x
Answers
Answer:
f(x) = 5(6.86)^x
Step-by-step explanation:
The function f(x) can be simplified according the the laws of mathematics. The expression is 5 multiplied by the 1.9^3x. You cannnot multiply 5 with 1.9 because 1.9 has a power of 3x. The 5 can only be multiply by the 1.9 if the 5 had a power of x or if 1.9 has a power of just 3. Therefore:
f(x) = 5×(1.9×1,9×1.9)^x = 5×(6.86)^x
f(x) = 5(6.86x)

Which line contains three equivalent expressions?
Answers
x²-x-6=(x+2)(x-3)
(x+0.5)²-6.25 =[x²+x+0.25]-6.25
=x²+x-6={x-3}{x+2}
2)
x²-x-2=(x+1)(x-2)
=(x-0.5)²-2.25={x²-x+0.25}-2.25
={x²-x-2}={x+1}{x-2}

To solve this mathematical expression. Here's a step-by-step solution:
1. Firstly, we have to follow the order of operations, also known as BIDMAS/BODMAS/PEDMAS: Brackets/Orders (or Parentheses/Exponents), Division and Multiplication (from left to right), Addition and Subtraction (from left to right).
2. Look for anything in parentheses (or brackets). We have (107.5 / 30). Let's solve this division problem first. The result is 3.5833333333333335.
3. The next step would be to multiply this result by 0.04 to follow the order of operations: 3.5833333333333335 * 0.04, which equals 0.14333333333333334.
4. Lastly, add 0.14 to the result of the multiplication which we've just calculated: 0.14 + 0.14333333333333334.
5. After doing the addition, we end up with the final answer, which is 0.2833333333333333.
I hope this breakdown clarifies the process of solving this relatively complex expression! Please let me know if you have any more questions.
