Step-by-step explanation:
your answer is correct
<u>Answer:</u>
5x = 100°
4x = 80°
<u>Step-by-step explanation:</u>
We are given a diagram with a straight line AC being intersected by another line BD and we are to find the two mentioned angles.
We know that the two angles (5x° and 4x°) are supplementary so their sum would be equal to 180°.
So we can write it as:
Finding the measure of both the angles:
100°
80°
Yes they can. They have to be more clear and collected
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
1.5 hours is half of 3
so 1.5+1.5=3 and 2.4+2.4=4.8
That person can walk 4.8 miles in 3 hours
Hope I helped :)
