Step-by-step explanation:
Answer:
d= 12.50 miles
Step-by-step explanation:
Kinematic equation of uniform motion (constant speed) :
v= d/t Formula (1)
v: velocity in miles per hour (mph)
d: distance in miles
t: time in hours
Data
v= 50 mph
t= 0.25 hours
Problem development
We replace data in formula (1)
50 mph=d/0.25 hour
d= 12.5 miles
d= 12.50 miles
Answer:
5x + 6y + 1

Answer:
40%
Step-by-step explanation:
Subtract 1,400 by 1,000 then divide by 1,000
Answer: This parabola has 0.3875 x-intercepts,
<span>representing the times when the dolphin's height above water is </span>
0 feet.
The x-intercept is the point where the graph crosses the x-axis, which is when the value is y=0.
The calculation for y=0 would be
<span>Y = -16x2 + 32x - 10
</span><span>0 = -16x2 + 32x - 10
</span>-8x2 + 16x - 5=0
-b +-√(b^2-4ac) /2a=
-16 +-√(16^2-4(-8)(-5)) /2(-8) =
-16+- √(256-160/ -16 =
-16+- √(96/ -16 =
-16+- 9.8/ -16 =
x1= 0.3875
x2= -1.6125
