Answer:
dC/dt = 2 mg*cm³/s
Step-by-step explanation:
Given
C(t)= (1/2)*(4t+ 4)- (1/2)
we apply dC/dt as follows
dC/dt = d((1/2)*(4t+ 4)- (1/2))/dt = (1/2)*(4) = 2
⇒ dC/dt = 2 mg*cm³/s
Answer:
1.
Step-by-step explanation:
I am assuming you want to simplify this.
cos^2 x + sin^2 x = 1 and
csc^2 x = 1 + cot^2 x so csc^2x - cot^2 x = 1
So the answer is 1/1 = 1.
It’s D!!! Hope this helped;)
Answer:
B
Step-by-step explanation:
The question is asking for the line that is perpendicular to AB.
Perpendicular means two lines intersecting making a 90 degree angle.
4x + 2 = -14
4x = -16
x = -4
4(-4) + 2 = -14
-16 + 2 = -14
-14 = -14
