Answer:
wait a minute I know this!
Step-by-step explanation:
5.3cm
2x+2(x-20)=340
2x+2x-40=340
4x=380
x=95 mph
x-20=75 mph
ans: the speed of the westbound train = 75 miles per hour
Answer:
- 2 seconds to maximum height
- 20 meters maximum height
- 4 seconds to reach the ground
Step-by-step explanation:
The function can be graphed using a graphing calculator, geometry app, or spreadsheet. One such graph is attached. Often, these tools are capable of identifying extrema and intercepts.
__
<h3>extreme</h3>
The vertex of the graph is reported as (x, y) = (2, 20). This means the maximum height is reached after 2 seconds. That maximum height is 20 meters.
__
<h3>intercept</h3>
The drop is launched from ground level at x = 0 seconds. It returns to ground level at x = 4 seconds.
Answer:
d = 69° , e = 32° , f = 79°
Step-by-step explanation:
d and 69° are vertically opposite angles and are congruent , so
d = 69°
e and 32° are vertically opposite angles and are congruent , so
e = 32°
69° , e , f lie on a straight line and sum to 180° , that is
69° + 32° + f = 180°
101° + f = 180° ( subtract 101° from both sides )
f = 79°
