As mentioned mean is b . you multiply it with 8 so the data would 8b.
Applying implicit differentiation, it is found that dy/dt when y=π/4 is of:
a-) -√2 / 2.
<h3>What is implicit differentiation?</h3>
Implicit differentiation is when we find the derivative of a function relative to a variable that is not in the definition of the function.
In this problem, the function is:
xcos(y) = 2.
The derivative is relative to t, applying the product rule, as follows:
Since dx/dt=−2, we have that:
When y = π/4, x is given by:
xcos(y) = 2.
Hence:
Since cot(pi/4) = 1, we have that:
Which means that option a is correct.

Answer:
if you're trying to find the discriminant, then it's 181.
Step-by-step explanation:
Answer:
When you dilate a shape by a scale factor of 2, you are just multiply the coordinates by 2.
So the points become:
A(2, 3) ===> A'(4, 6)
B(3, 5) ===> B'(6, 10)
C(7,4) ===> C'(14,8)
Absolute value = how far away the number is from zero
(If number is positive it stays the same and if number is negative it turns positive)
So the answer is 55
