Y is directly proportional to the square root of x
1 answer:
Answer:
y = 20
Step-by-step explanation:
Given y is directly proportional to , then the equation relating them is
y = k ← k is the constant of proportion
To find k use the condition y = 32 when x = 64, then
32 = k = 8k ( divide both sides by 8 )
4 = k
y = 4 ← equation of proportion
When x = 25, then
y = 4 = 4 × 5 = 20

Answer:
A.
Step-by-step explanation:
We have that, ΔABC is transformed to get ΔA''B''C''.
We see that the following transformations are applied:
1. Reflection across x-axis i.e. flipped across x-axis.
Now, ΔABC is reflected across x-axis along the line AC to get ΔA'B'C'.
2. Translated 2 units down i.e. shifted 2 units down and and then translated 6 units to the left i.e. shifted 6 units to the left.
So, ΔA'B'C' is translated 2 units downwards and 6 units to the left to get ΔA''B''C''.
Hence, the sequence of transformations is Reflection across x-axis and then Translation of 2 units down and 6 units left.
