Answer:
a) 16.25 centimeters
b) 6.8 centimeters
Step-by-step explanation:
We can set up a proportion for both of these problems.
a) Look at the longest side of each triangle. We can set up a fraction: 7.2/18. We can also set up a fraction for XZ and PR:
6.5/x
x represents the length you're trying to find.
Since the triangles are similar, we have an equation:
7.2/18=6.5/x
Cross multiply
16.25
XZ is 16.25 centimeters long.
b)
We can do same thing:
7.2/18=x/17
Cross multiply
6.8
QR is 6.8 centimeters long.
Hope this helps!
Easily we can use formula y=(x-h)^2 +k
as equation of a parabola if vertex was (h,k):
Y=(x-1)^2 + 3
and maybe node (2,6) is incorrect for this vertex of a parabola!!!
Answer:
public class MovieRental
{
public static void main(String[] args)
{
Scanner in = new Scanner(System.in);
System.out.print("Enter the number of movie rentals: ");
int movieRentals = in.nextInt();
System.out.print("Enter the number of members referred to the video club: ");
int memberReferral = in.nextInt();
in.close();
double discountVal = Math.min(movieRentals + memberReferral, 75);
System.out.println("The discount is equal to: " + discountVal);
}
}
