Radius = r = 1 foot
Angular velocity = w = 1 revolutions in 4 seconds
So,
w = 0.25 revolutions per second
Since,
1 revolution = 2π radians
We can write the above equation as:
w = 0.25 x 2π radians per second = 0.5π radians per second
Linear Velocity = v = r w
Using the values, we can write:
v = 1 x 0.5π
= 0.5 π
= π/2 feet per second
Therefore, the correct answer is option B
Answer:
-7
Step-by-step explanation:
there is nothing to explain but anyways
-4 - 3 = -7
Answer:
.
Step-by-step explanation:
How many unique combinations are possible in total?
This question takes 5 objects randomly out of a bag of 50 objects. The order in which these objects come out doesn't matter. Therefore, the number of unique choices possible will the sames as the combination
.
How many out of that 2,118,760 combinations will satisfy the request?
Number of ways to choose 2 red candies out a batch of 28:
.
Number of ways to choose 3 green candies out of a batch of 8:
.
However, choosing two red candies out of a batch of 28 red candies does not influence the number of ways of choosing three green candies out of a batch of 8 green candies. The number of ways of choosing 2 red candies and 3 green candies will be the product of the two numbers of ways of choosing
.
The probability that the 5 candies chosen out of the 50 contain 2 red and 3 green will be:
.
Using it's concept, it is found that the range of the function
is given by:
all real numbers greater than 0.
<h3>What is the range of a function?</h3>
It is the set that contains all possible output values for the function.
In this problem, the function is:
![f(x) = 9^x](https://tex.z-dn.net/?f=f%28x%29%20%3D%209%5Ex)
For <u>exponential functions without vertical shifts</u>, as is the case in this problem, the range is given by:
all real numbers greater than 0.
