I hope this answer your question.
Remark
the question depends on d= r * t
d = the distance in miles.
r = the rate of travel in miles per hour
t = the time in hours.
Step One
Rearrange the formula so you are solving for the rate.
d = r * t Divide by t
4 5/6 = (4*6 + 5)/6 = 29/6
r = d / t
Step Two
Substitute into the equation.
Step Three
Turn the bottom fraction upside down. Multiply these two together.
r =
r = 29/4 miles hour.
Step Four
Solve for d when t = 1 hour.
d = ??
r = 29/4 miles / hour
t = 1 hour.
d = 29/4 * 1
d = 29/4 miles
That's as simple as you can get it unless you want 7 1/4 miles or 7.25 miles
The x value of the vertex in
ax^2+bx+c is -b/2a
y value is just sub for x
3x^2-6x+5
x value of vertex is -(-6)/(2*3)=6/6=1
sub back
y=3(1)^2-6(1)+5
y=3(1)-6+5
y=3-1
y=2
vertex is (1,2)
Answer:
Step-by-step explanation:
The edges of length and width of a piece of printer paper perpendicularly intersect each other.
=> Perpendicular Lines are those making an angle of 90 degrees with each other.
