The formula for exponential decay is
where a is the initial value (28750)
r is the rate of decrease (0.12)
x is the time, in this case in years (6 . 2018-2012 = 6 years)
<span>y </span>≈ <span>13351.62</span>
Answer:
x=1/4 , y=-1/4. You can confirm this by substituting the numbers in.
Step-by-step explanation:
If you would like to know the number of square feet of grass seeds that the lawn company can spread per hour, you can calculate this using the following steps:
7500 square feet ... 2 1/2 hours = 5/2 hours
x square feet = ? ... 1 hour
7500 * 1 = 5/2 * x
7500 = 5/2 * x /*2/5
x = 7500 * 2 / 5
x = 3000 square feet
The correct result would be 3000 square feet.
Answer:
3x² + 6x + 4
Step-by-step explanation:
6x + 7 + x² + 2x² - 3
→ Collect like terms
x² + 2x² + 6x + 7 - 3
→ Simplify
3x² + 6x + 4
