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:
2/3
Step-by-step explanation:
This problem is an overlap problem. First we have that 1/8 total tried out for football team, 1/6 total tried out for baseball team and 1/12 of the students that tried out for both football and baseball team.
So if we want to find those who just tried football, we perform the following operation:
1/8 - 1/12 = 1/24.
So we know that 1/24 tried out just football.
If we want to find all those who tried out just for baseball, we perform the following operation:
1/6 - 1/12 = 1/12
So we know that 2/24 (1/12 multiplied by two) tried for both football and baseball and 3/24 tried out for football, it means that 2/3 of the boys who tried football also tried baseball.
Answer:
(x^2-6)(x+2)(x-2)
Step-by-step explanation:
x^4-10x^2+24
(x^2-6)(x+2)(x-2)
<span>10x+y=19
when x = 10:
substitute with x=10 into the equation given:
10(10) + y = 19
or:
100 + y = 19
bring 100 to the other side to be -100
y = 19 - 100
y = -81
That's it
