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
Answer: A and C
Step-by-step explanation:
So the largest rectangle has sides of 5 length and 2+4 width or 6 right. so 5*6=30 Now we have to find which of these expressions solve to get 30. I would just solve them all but the answer is
A and C
Step 1
<u>Find the value of s</u>
we know that
In a Rhombus all sides are congruent
so


equate AB and CD

Combine like term


<u>The answer Part a) is</u>
the value of s is 
Step 2
<u>Find the value of side AB</u>

substitute the value of s

Remember that the sides are congruent

therefore
<u>the answer Part b) is</u>
The length of the side BC is 
O2, or Oxygen, and C6H12O6, or glucose.

because it's a linear function.
