We have 15 ways to chose 2 students for the position of president and Vice President
<em><u>Solution:</u></em>
Given that,
There are 6 students. 2 of them are chosen for the position of president and Vice President.
<em><u>To find: number of ways we have to choose the students from the 6 students</u></em>
So now we have 6 students, out of which we have to choose 2 students
As we just have to select the students. We can use combinations here.
In combinations, to pick "r" items from "n" items, there will be ways
<em><u>Then, here we have to pick 2 out of 6:</u></em>
Total students = n = 6
students to be selected = r = 2
Thus we have 15 ways to chose 2 students for the position of president and Vice President
18 mile per hour
Step-by-step explanation:
average speed = total distance covered by total time taken
so, avg. speed = ( 2+ 7 ) / ( 20 + 10 )
= 9 / 30
= 3 / 10
= 0.3 miles per minute
= 18 mile per hour
C = 2 * (pi) * r
C = 2 * (pi) * 3.5.....3 1/2 = 3.5
C = (2 * 3.5) * (pi)
C = 7(pi) cm <===
Answer:
by translating or scaling the function
Step-by-step explanation:
The parent absolute value function f(x) = |x| does not extend below the x-axis. The graph of a translated (and/or scaled) version of the function may extend below the x-axis.
In the attachment, one function has simply been translated down 3 (and right 2) so that it extends below the x-axis. The other one has been scaled by a negative number, so it does not go above the x-axis.
