Answer:
12
Step-by-step explanation:
Lets c = chord inside circle
3(3 + c) = 6^2
9 + 3c = 36
3c = 27
c = 9
x = 3 + 9
x = 12
Answer: -15x - 23
Step-by-step explanation:
There u go- Lily ^_^
1) Volume = π r² h/3
V = 3.14 * (5cm)² * 10cm/3
V = 3.14 * 25cm² * 3.33cm
V = 261.41 cm³
2) M1 = 1,1; N1 = 3, -1 ; O = -2, -3 ; P1 = -2, 2
M2 =3,3 ; N2 = 9, -3 ; O = -6, -9 ; P2 = -6, 6
Point 2 / Point 1
x y
M = 3/1 = 3 ; 3/1 =3
N = 9/3 = 3 ; -3/-1 = 3
O = -6/-2 = 3 ; -9/-3 = 3
P = -6/-2 = 3 ; 6/2 = 3
Answer is A.) (x,y) ⇒ (3x, 3y)
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.
