Let
x-------> the time
y-------> the altitude of a helicopter
Step 1
<u>Find the slope of the line</u>
we know that
the slope m of the line between two points is equal to
we have
substitute in the formula
therefore
<u>the answer is the option </u>
The slope is . This means that the helicopter descends
ft each minute.
Answer:
The goalkeeper has 0.306 seconds to react, dive, and reach the ball before it crosses the goal line.
Step-by-step explanation:
We use the following relation to solve this question:
In which v is the velocity, d is the distance, and t is the time.
Chastain will kick the ball from 18 yards away from the goal at 120 miles per hour.
Since the velocity is in miles per hour, the distance has to be in yards.
Each yard has 0.000568182 miles, so the ball will be kicked from 18*0.000568182 = 0.0102 miles.
This means that
How many seconds does the goalkeeper have to react, dive, and reach the ball before it crosses the goal line?
We have to find t, first in hours. So
An hour has 3600 seconds. So
3600*0.000085 = 0.306.
The goalkeeper has 0.306 seconds to react, dive, and reach the ball before it crosses the goal line.
Answer:
8.695=area of shaded region
Step-by-step explanation:
pi x 16=50.265
this is the whole circle
the radius is also the side of the hexagon
the picture is formula for area of hexagon
if you replace a by the side which is 4
the answer is 41.57
50.265-41.57=8.695
