The equation is:
f(x) = 2x² - 44x + 185
f(x) = 2(x² - 22x + 121 - 121) + 185 =
= 2(x² - 22x + 121) - 242 + 185 =
= 2(x - 11)² - 57
Conclusion:
The vertex is located at (11, -57) and the vertex form is: f(x) = 2(x - 11)² - 57
Hello!
--------------------------------------------------------
Solution:
The ratio is expressed as 4 to 1.
Add these parts together.
4 + 1 equals 5.
Now divide.
150 divided by 5 results in 30.
Next, multiply to find Ivan's share.
30 multiplied by 4 gives us 120.
30 multiplied by 1 equals 30 for Tanya.
Verify.
120 plus 30 totals 150.
Then subtract.
120 minus 30 equals 90.
