The only difference between speed and velocity is that velocity also includes direction, so if the speed is the same but the velocity is changing, that means that the direction is changing on the ride, but the speed is staying the same.
If <span>ZW is an altitude of △XYZ, then m</span>∠ZWY = 90°
3a + 5 + 5a + 13 = 90
8a + 18 = 90
8a = 72
a = 72/8
a = 9
<span>m∠ZWT = 3a + 5 = 3*9 + 5 = 27 + 5 = 32</span>°
8/9 it the answer to the question
Radius = 11 / 2 = 5.5
A = π * 5.5 * 5.5
A = 30.25 <span>π
</span>
3025 / 100 <span>π mm^2</span>
<span> x = 10<span> x = 4 </span></span>Two real solutions:
x =(14+√36<span>)/2=7+3= 10.000 </span>
or:
x =(14-√36)/2=7-3= 4.000
