Step-by-step explanation:
The solutions are in the dark red area, with some on the continuous blue line but none on the red dotted line.
70mi/1hr x 1hr/60min x 1min/60sec= .0194/1sec
Answer:
The solutions are
t=2.07 sec and t=5.43 sec
Step-by-step explanation:
The question in English
The height h above ground level (in feet) of a toy rocket, t seconds after it is launched, is given by h = -16t2 + 120t. When will the rocket be 180 feet above the ground?
we have
-----> equation A
-----> equation B
equate the equation A and equation B
------> equation C
we know that
The solution of the equation C is equal to the x-coordinate of the intersection point of the graph equation A and the graph of the equation B
so
using a graphing tool
The solutions are
t=2.07 sec and t=5.43 sec
see the attached figure to better understand the problem
The angle show with the yellow square has a measure of 90°.
Together with angles 1 and 2, they form a straight angle so we have:
∠1+∠2+90°=180°,
subtracting 90° from both sides we have:
∠1+∠2=90°
If the sum of the measures of 2 angles is 90°, the angles are called complementary.
Since the sum of the measures of angles 1 and 2 is 90°, then these 2 angles are complementary.
Answer: <span>They are complementary</span>
