Answer:
The length of an arc is, 31.41594 cm
Step-by-step explanation:
The arc length of the circle(l) is given by:
....1[]
where
r is the radius of the circle
is the angle in radian.
As per the statement:
For a circle with the radius of 15 cm and angle is 120 degree.
⇒r = 15 cm and angle in degree = 120
Use conversion:
1 degree = 0.0174533 radian
then;
120 degree = 2.094396 radian
⇒
Substitute the given values in [1] we have;
⇒l = 31.41594 cm
Therefore, the length of an arc is, 31.41594 cm
The answer to this question will depend on the function f itself. Basically you will find the height in meters above the ground of the bird when it jumped when the time t=0s. This is substsitute every t in the function for a value of zero and that way you will get the bird's height at the time it jumped. If you were given a graph for this function, you can find the y-intercept of the graph and that will be the answer as well. The question could be written like this:
A baby bird jumps from a tree branch and flutters to the ground. The function "" models the bird's height (in meters) above the ground as a function of time (in seconds) after jumping. What is bird's height above the ground when it jumped.
Answer:
25m
Step-by-step explanation:
Once your function is given, you can substitute t=0 since 0s is the time measured at the moment the bird jumped. So our function will be:
So the height of the bird above the ground when it jumped is 25m in this particular function.
