Answer:
19.6 cm²
Step-by-step explanation:
The formula of the area of a circle
= πr²
The radius of the circle
= 5÷2
= 2.5 cm
The area of the circle
= π×2.5²
= 19.63495...
= 19.6 cm² (rounded to the nearest tenth)
Answer:
Option A. (6,2)
Step-by-step explanation:
We have the following inequality:
Solving for y we have:
The line that limits the region of inequality is
Then the region of inequality are all values of y that are less than
In other words, the points belonging to the inequality are all those that lie below the line.
To find out which point belongs to this region substitute inequality and observe if it is satisfied
A. (6,2)
<em> is satisfied</em>
B. (2, 6)
<em>it is not satisfied</em>
C. (2, -1)
it is not satisfied
<em>The answer is the option A</em>
Answer: a) 48
b) 43
Step-by-step explanation:
Given : The number of students Professor Date has in his Calculus class = 31
The number of students Professor Date has in his Discrete Mathematics class = 17
(a) If we assume that there are no students who take both classes, then the total number of students Professor Date Has = 31+17=48
(b) If we assume that there are five students who take both classes, then the total number of students Professor Date Has = 31+17-5=43
