Mathematics
1 answer:
Jet001 [13]4 years ago
6 0

Answer:

3.25

Step-by-step explanation:

The slope formula is slope = y2 - y1 / x2 - x1 and the variables are found by assigning them with their corresponding values. Here, x1 = -9, x2 = -13, y1 = 18, and y2 = 5. Next, substitute these values in and get 5 - 18 / -13 - (-9). This can fully simplify to 13 / 4 or 3.25.

The function f(x) = 200(0.5)x/50 models the amount in pounds of a particular
victus00 [196]

<u>Answer:</u>

29 years

<u>Step-by-step explanation:</u>

  • Given the function f(x)= 200(0.5)^{\frac{x}{50} }, where x stands for the number of years since the material was put into the vault, we can plug 140 into x to find the amount leftover.
  • Another way of doing this is to change the function to f(x)=200(0.5^{\frac{1}{50} })^{x} which are equivalent functions, and then plug 140 into x. This function is helpful if you also needed to find the rate.
  • I'll use the 1st function because the question doesn't ask for the rate

f(x)= 200(0.5)^\frac{140}{50}}

From here I'll just use a calculator & get 28.7, or 29 years.
