In ΔPQR, p = 75 inches, q = 73 inches and r=35 inches. Find the measure of ∠P to the nearest 10th of a degree.
Answer:
79.5
Step-by-step explanation:
a^2 =b^2+ c^2-2bc cos A
cos p = 73^2+35^2-75^2/2(73)(35)
cos p= 9229/5110
cosp=79.5
The measure of ∠P to the nearest 10th of a degree is 79.5
What is a cosine law?Cosine law is a formula relating the length of the sides of a triangle to the cosine of one angle of the triangle.
u² = s² + t² - 2(s)(t)·cos U
We are given that In ΔPQR, p = 75 inches, q = 73 inches and r=35 inches.
u² = s² + t² - 2(s)(t)·cos U
Now substituting;;
cos p = 73²+35²-75² /2(73)(35)
cos p= 9229/5110
cosp=79.5
The measure of ∠P is 79.5

The time spent watching a movie. Discrete or Continuous?
Answer:
The durations of movies in minutes can only take on integer values from 0 to 60. Therefore, it is a discrete data.
The time spent watching a movie is an example of Continuous function.
What is the difference between Discrete and Continuous?We gather information to look for connections, patterns, and other ideas. For instance, if you keep track of how many push-ups you perform every day for a month, your overarching objective is to assess your development and rate of advancement. For example heart beat rate, signal, etc.
Numerical information that is continuously referred to the undefined variety of measurements that might be taken across two realistic sites. For example - time, wind, temperature, pressure, etc.
Despite the fact that these numbers are often gathered via accurate measurements, they are also not necessarily neat and orderly as those in categorical data.
The time spent watching a movie is an example of Continuous function.
