11/8 or 13/8 is the answer.
Step-by-step explanation:
If two lines cross each other the angles opposite of each other are the same. So left=right and top=bottom. Knowing this the bottom angle must be 120°. if 3x=120° then x=40°
A ) v = v o + g t
h = v o * t + g t² /2
10 m = 9.81 m/s² * t² / 2
9.81 t² = 20
t² = 2.038
t = 1.4278 s
v = 0 + 9.81 * 1.4278
v = 14 m/s
b ) v o = 14 m/s
v = v o² + 2 a d
0 = 14² + 2 a * 2.9
196 = - 5.9 a
a = 196 : ( - 5.9 )
a = - 33.79 m/s² ( the magnitude of his acceleration while in water )
c ) The total amount of force exerted on the swimmer in water:
F = m * a = 65 kg * 33.76 m/s²
F = 2,196.55 N
Step-by-step explanation:
a. represent the man's current age by n. Two years ago his age was n - 2.
b. Multiplication of n by the product of y and z would be (y×z)×n.
In the pictured graph, the X axis is labeled as real Axis and the Y axis is labeled as Imaginary axis.
The letter i after a number is considered an imaginary number.
So in the given numbers 2 +2i the w is the real number and 2i is the imaginary number, which is located at the dot labeled B.
-1 +3i, -1 is the real number and 3i is the imaginary number, which is located at the dot labeled A.
Line Segment AB is the correct answer.
