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
Step-by-step explanation:
a. Area = 121 ft²
s² = 121
s = √121
Therefore s = 11 ft
b. Area = 81 yd²
s² = 81
s = √81
Therefore s = 9 yd
c. Area = 324 cm²
s² = 324
s = √324
Therefore s = 18 cm
d. Area = 361 mi²
s² = 361
s = √361
Therefore s = 19 MI
