Answer:
Length = 9 units
Explanation:
Length between two points...,
Apply the following formula,
Length = square root of [(difference in x coordinates)^2 + (difference in y coordinates)^2]
Length = square root of [ (4 - 0)^2 + (7 - -1)^2 ]
Length = square root of (80)
Length = 9 units
<h2>
Answer:38.33 Kg</h2>
Step-by-step explanation:
If 
of mass is placed on spring with spring constant 
,
where 
is universal gravitational constant
is the displacement in the spring.
In case 1:
In case 2:
Using result from case 1,
Answer:
- 10.5cm,20.8cm,23.3cm — yes
- 6cm, 22.9cm,20.1cm — no
Step-by-step explanation:
If the sides form a right triangle, the sum of the squares of the shorter two sides will equal the square of the longest side.
1. 10.5^2 + 20.8^2 = 23.3^2 . . . . . true algebraic statement; right triangle
__
2. 6^2 +20.1^2 = 440.01 ≠ 22.9^2 = 524.41 . . . . . this is an obtuse triangle
Answer: 2(x + 4)(x - 4)
Hope this helped!
