Answer:
x ≈ 39.3°
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos x = = = , then
x = ( ) ≈ 39.3° ( to the nearest tenth )
Answer:
Step-by-step explanation:
Decay is defined by the function as,
f(t) =
Here, r = rate of decay
t = duration of decay Or time (In years)
n = Number of times of decay in a year
Decay every 2 years over a period of t years,
f(t) =
=
Therefore, will be the answer.
Decay 2 times a year over a period of t years,
f(t) =
Therefore, will be the answer.
Decay once per year over a period of t years,
f(t) =
=
Therefore, will be the answer.
I think its 3,600, because you usually have to multiply the numbers.
Answer:
Step-by-step explanation:
This is a right triangle problem. The reference angle is x, the side opposite the reference angle is 32, and the hypotenuse is 58. The trig ratio that relates the side opposite a reference angle to the hypotenuse is the sin. Filling in accordingly:
Because you are looking for a missing angle, you will use your 2nd button and then the sin button to see on your display:
Within the parenthesis enter the 32/58 and you'll get your angle measure. Make sure your calculator is in degree mode, not radian mode!!!
