Answer:
Distance = 5
Step-by-step explanation:
x2 = 3
y2 = 1
x1 = 7
y1 = -2
=> d = Square root of (3 - 7)^2 + (1 + 2)^2
=> d = Square root of (-4)^2 + (3)^2
=> d = Square root of 16 + 9
= d = Square root of 25
d = 5
Answer: With no choices given here, here are a few possibilities.
If it is not a right triangle, the third side could be any number less than 50 cm
If it is a right triangle, the third side could be the hypotenuse, which would be 10√13 or about 36.05 cm.
If 30cm is the hypotenuse, the other side would be 10√5 or about 22.36 cm
Step-by-step explanation: If the two given sides add up to 50, they flatten out to a straight line, equal to the third side, so it is no longer a triangle. The third side must be less than the sum of the other two sides.
We can use the Pythagorean Theorem a² + b² = c² to calculate the lengths of the sides of a right triangle.
For example
20² + 30² = c²
400 + 900 = c²
1300 = c²
√1300 = √(100)(13) = √c²
10√13 = c ≈ 36.05
(0,0),(-1,2)
slope = (2 - 0) / (-1 - 0) = - 2/1 = -2
so this equation, since it goes thru the origin, is : y = -2x or 2x + y = 0
(2,3),(1,-2)
slope = (-2 - 3) / (1 - 2) = -5/-1 = 5
y = mx + b
slope(m) = 5
(2,3)...x = 2 and y = 3
now sub into the formula and find b, the y int
3 = 5(2) + b
3 = 10 + b
3 - 10 = b
-7 = b
so this equation is : y = 5x - 7 or 5x - y = 7
so ur 2 equations are :
2x + y = 0
5x - y = 7
Step-by-step explanation:
(-1,3)
just move the point over 5 lines and then up 4 lines. or
4-5 = -1
-1 +4=3
