Answer:
Step-by-step explanation:
Given that, r varies inversely with u. r=k÷u, k being the constant.
Therefore, k=8×5, ( after making k the subject of your formula).
This implies that k=40.
Now, according to the formula r=k÷u,
r=40÷55
Therefore, r=0.72
Answer:
2/5
Step-by-step explanation:
If you have two point of the form(x_1,y_1) and (x_2,y_2) then the distance between these points is d=√(x_1-x_2)^2+(y_1-y_2)^2
In this case:
d=/(-8-(-6))^2+(-2-2)^2
d=/(-8+6)^2+(-4)^2
d=/(-2)^2+16
d=/4+16
d=/20
d=2/5
Answer:
6 square inches
Step-by-step explanation:
The area of the triangle is
A = 1/2 bh where b is the base and h is the height
b= 4 inches and h = 3 inches
A = 1/2 * 4* 3
A = 1/2 * 12
A = 6 inches ^2
