Answer:
sin90° = 1.
Step-by-step explanation:
Using the diagram, we notice that the side opposite of the 90° angle is the hypotenuse itself.
Therefore sin90° = Hypotenuse/Hypotenuse = 1.
Answer:
N(t)=N∗.5t/h where n(t) is amount of substance left, N = initial amount, t = current time, and h = half-life time.h = 24 hours t= 45 hours, N = 130mg
therefore, N(t)=130∗.545/24=35.44mg
Step-by-step explanation:
N(t)=N∗.5t/h where n(t) is amount of substance left, N = initial amount, t = current time, and h = half-life time.h = 24 hours t= 45 hours, N = 130mg
therefore, N(t)=130∗.545/24=35.44mg
-4 (-5x+4w-1)
Multiply -4 by everything in the parenthesis:-4 * -5w = 20w
-4 * 4w = -16w
-4 * -1 = 4
20w - 16w + 4
And if you need it more simplified:
4w + 4
Answer:
3 over 2 terminates 3 over 4 terminates
Step-by-step explanation:
3 over 2 = 1.5 and 3 over 4 = .75
