Because we're given two points on the line, we can apply the slope formula to find the answer:
![\frac{y.2 - y.1}{x.2 - x.1} = m](https://tex.z-dn.net/?f=%5Cfrac%7By.2%20-%20y.1%7D%7Bx.2%20-%20x.1%7D%20%3D%20m)
-4 - 8 / 2 - (-1)
-12 / 3
-4
<h3>The slope of the line is -4.</h3>
Answer:
base times height divided by 2 i think i remember
Step-by-step explanation:
Because it's a triangular prism and the base times height makes a rectangular prism, a triangle is half of a rectangle
Answer:
Hey! If you'd like to know the answer, please look below.
1, 2, 3, 6
THE GCF of 6 and 12 is 6
Part 1:
Given that a<span>
store had 235 MP3 players in the month of January and that every month, 30% of
the MP3 players were sold and 50 new MP3 players were stocked in the
store.
</span>The number of MP3 players in the store after the previous months sale is given by 0.7f(n - 1) and <span>the number of MP3 players in the store after new MP3 were added is 0.7f(n - 1) + 50.
Therefore, the </span><span>recursive function that best represents the number of MP3 players in the store f(n) after n months is given by </span><span>f(n) = 0.7 x f(n − 1) + 50, f(0) = 235, n > 0
Part 2:
The average rate of change of a function from a to b is given by
![average \ rate \ of \ change= \frac{f(b)-f(a)}{b-a}](https://tex.z-dn.net/?f=average%20%5C%20rate%20%5C%20of%20%5C%20change%3D%20%5Cfrac%7Bf%28b%29-f%28a%29%7D%7Bb-a%7D%20)
Given that the </span><span>equation showing the value of her investment after x years is given by
![f(x)=500(1.05)^x](https://tex.z-dn.net/?f=f%28x%29%3D500%281.05%29%5Ex%20)
Thus, </span><span>the average rate of change of the value of Sophia's investment from the second year to the fourth year is given by
![Average \ rate \ of \ change= \frac{f(4)-f(2)}{4-2} \\ \\ = \frac{500(1.05)^4-500(1.05)^2}{2} = \frac{607.75-551.25}{2} \\ \\ = \frac{56.5}{2} =28.25](https://tex.z-dn.net/?f=Average%20%5C%20rate%20%5C%20of%20%5C%20change%3D%20%5Cfrac%7Bf%284%29-f%282%29%7D%7B4-2%7D%20%20%5C%5C%20%20%5C%5C%20%3D%20%5Cfrac%7B500%281.05%29%5E4-500%281.05%29%5E2%7D%7B2%7D%20%3D%20%5Cfrac%7B607.75-551.25%7D%7B2%7D%20%20%5C%5C%20%20%5C%5C%20%3D%20%5Cfrac%7B56.5%7D%7B2%7D%20%3D28.25)
Therefore, the </span><span>average rate of change of the value of Sophia's investment from the second year to the fourth year is 28.25 dollars per year.</span>
The graph should look most like graph D.
