Answer:
71°
Step-by-step explanation:
The cosine of an angle is equal to the sine of its complement:
cos(19°) = sin(90° -19°) = sin(71°)
Comparing to the given expression, we see that x = 71°.
Answer:
57.420
Step-by-step explanation:
The y intercept is always the number on the out side next to the slope which is 2.391
Answer:
(-3,6)
Step-by-step explanation:
When you flip or reflect over the y axis, the x value changes in the original ordered pair, but the y value stays the same
so the original ordered pair is (3,6) so the reflected ordered pair would be (-3,6)
The volume of water that goes into the hose is the same as the volume of water that comes out the nozzle. This means the velocity is inversely proportional to the area. The area is proportional to the square of the diameter.
Taken together, these facts mean that if the diameter is divided by a factor of 3, the velocity is multiplied by a factor of 3^2 = 9.
Nozzle velocity = 3^2 * entering velocity
.. = 9 * (4 m/s)
Nozzle velocity = 36 m/s . . . . . . . . . corresponding to selection A
