Answer:
Step-by-step explanation:
<u>Given function:</u>
<u>Convert the equation into vertex form:</u>
- y = 5x² - 20x + 20 + 4 =
- 5(x² - 4x + 4) + 4 =
- 5(x - 2)² + 4
Vertex is (2, 4) at which the minimum y-value is 4
Correct choice is C
Ratio is just a fraction in other form. To create ratio we can just make fraction and transform it into ratio, so
Now we can simplify the ratio/fraction
= 4:3 - its the result
Answer:
A' = 6(3t +1)
Step-by-step explanation:
The area is the square of the side length, so ...
A = (3t +1)²
The derivative with respect to t is then
A' = 2(3t +1)·(3) = 6(3t +1)
If you like, you can multiply out the area expression first, then differentiate.
A = 9t² +6t +1
A' = 18t +6
This can be factored, if you like, to ...
A' = 6(3t +1)
