Answer:
C
Step-by-step explanation:
Triangle CGF and triangle CED are similar. Hence, the ratio of their corresponding sides are equal. Thus we can write:
<em>We can now cross multiply and solve for CD:</em>
Since GF is a midsegment of CDE, CD is double of CF. So we can write:
<em>By using quadratic formula 
and with a=3, b= -5.2, and c= -1.6, we find the value of x to be:</em>
<em>Since the expression for CD is 
, we plug in 
into this expression to find value of CD:</em>
The correct answer is C
Answer:
B
Step-by-step explanation:
The munimum value is, at x = 3/10, y = 5 and 10x+3y/5 = 6.

What are nonnegative real numbers?</h3>
- Non-negative real numbers are the set of positive real numbers that are bigger than 0 (zero).
- That is, the true values are either positive or negative.
- The collection will include numbers such as 0, 1, 2, 3, 4, 5, and so on.
To find the minimum value of 10x (3y/5):
Given - y = 3/(2x)
So, we want the bare minimum of,
- = 10x + 3/5 × 3/(2x)
- = 10x + 9/(10x)
Take the derivative to obtain:
When you set it to zero, you get:
- = 100x^2 - 9 = 0
- = (10x-3)(10x+3) = 0
- = x = ± 3/10
So, at x = 3/10, y = 5 and 10x + 3y/5 = 3 + 3 = 6.
Therefore, the munimum value is, at x = 3/10, y = 5 and 10x+3y/5 = 6.
