Answer:
(3 1/2, 7 1/4)
Step-by-step explanation:
When the segments have the ratio 1:3, the shorter segment is 1/(1+3) = 1/4 of the total length.
The point P that divides the length that way will be ...
... P = A + (1/4)(B - A)
... = A - 1/4A + 1/4B
... = (3A +B)/4
... = (3(2, 8) +(8, 5))/4 = (14/4, 29/4)
... P = (3 1/2, 7 1/4)
Answer:
C. arm span, foot length is predicted to increase by about 0.186 cm.
Step-by-step explanation:
edge 2020
We know that
<span>applying the Pythagorean theorem
c</span>²=a²+b²
c is the <span>length of the diagonal
a=100 yd
b=130 yd
c</span>²=100²+130²-------> c²=26900---------> c=√26900 units----> c=10√269 units
the answer is
the length of the diagonal is 10√269 units or 164.012 units
Answer:
Step-by-step explanation:
The formula we need here is

which simplifies to

which simplifies to
36 + 6x = 40 + 5x and
x = 4
So DG = 5 + 4 + 3 which is 12
Answer:
y = 4
Step-by-step explanation:
Note that A and B have the same x-coordinate: 1. This means that AB is a vertical line through x = 1. The perpendicular bisector of AB must be a horizontal line situated halfway between y = 3 and y = 5. Thus, it's just y = 4.
Review: y = 4 bisects AB and represents a horizontal line.
