None of the lenses on that list is a converting lens.
None are converging either.

Answer:
(a) F = 320
(b) = F = -5.1625
Explanation:
The formula that converts degree Celsius (C) to degree Fahrenheit (F) is:
F = 1.8C + 32
Solving (a): F = 2C
Substitute 2C for F in the above equation
F = 1.8C + 32
2C = 1.8C + 32
Collect like terms
2C - 1.8C = 32
0.2C = 32
Multiply both sides by 5
5 * 0.2C = 32 * 5
C = 160
Recall that F = 2C
F = 2 * 160
F = 320
Solving (b): F = ¼C
Substitute ¼C for F in the above formula
F = 1.8C + 32
¼C = 1.8C + 32
Convert fraction to decimal
0.25C = 1.8C + 32
Collect like terms
0.25C - 1.8C = 32
-1.55C = 32
Divide both sides by -1.55
C = 32/(-1.55)
C = -32/1.55
C = -20.65
Recall that: F = ¼C
F = -¼ * 20.65
F = -5.1625
Answer:
Step 1: Draw the vectors[Ref. Fig.]
Consider there are two vectors A and B such that B is perpendicular to the resultant R
Since the resultant is perpendicular to vector B we will get a right-angled triangle
Step 2: Equation formation
From the triangle
∣A∣2=∣B∣2+∣R∣2 ....(1)
Given , ∣R∣=∣A+B∣=12 ....(2)
∣A∣+∣B∣=18 ....(3)
Step 3: Solving Equations
Equation (3) and (1)⇒ ∣A∣2=(18−∣A∣)2+(12)2
⇒ ∣A∣2=182+∣A∣2−2×18∣A∣+
