Step-by-step explanation:
Domain: {0≤ x ≤ 26}
Range: { 0≤ y ≤ 20}
Find the following values:
f(18) = 16
f(5) = 2
f(17) = 14
Answer: A' (5,9)
Step-by-step explanation:
1. You have that the translation is
⇒
and the coordinates of A is (-2,5). Then:
⇒![A(5,-5)](https://tex.z-dn.net/?f=A%285%2C-5%29)
2. As you can see, -5 is 7 units below of the line of reflection
, therefore, you can know the coordinates of A' as following:
![A'(5,7+2)\\A'(5,9)](https://tex.z-dn.net/?f=A%27%285%2C7%2B2%29%5C%5CA%27%285%2C9%29)
3. Then, the coordinates of A' is (5,9)
Answer:
b
Step-by-step explanation:
Answer:
W1 = W2 = 50k Joules (assuming W1 and W2 have the same force constant, k)
W1 - W2 = 0
Step-by-step explanation:
Work done in stretching a spring is given by 1/2ke^2
Where, k is force constant and e is extension
e1 = 30cm - 20cm = 10cm
W1 = 1/2k(e1)^2 = 1/2×k×10^2 = 50k Joules
e2 = 40cm - 30cm = 10cm
W2 = 1/2k(e2)^2 = 1/2×k×10^2 = 50k Joules
W1 = W2 = 50k Joules provided W1 and W2 have equal force constant
Therefore, W1 - W2 = 0
