Answer:
Add 3 feet to the length
Step-by-step explanation:
14 times 9 is 126
Answer:
Hans:6
Eric:18
Kaitlin:74
Step-by-step explanation:
first create an equation using the information in the question
5h+68=98
first subtract 68
5h+68=98
-68 -68
5h=30
divide by 5
Hans:6
multiply by 3
Eric:18
68+6=74
Kaitlin:74

so... if you notice, the vertex is at h,k and that'd be the origin, 0,0
so...since the directrix is "p" units from the vertex, so it'd be 2 units from 0,0
now, the parabola has an equation with a positive leading term's coefficient, namely the 1/8 is positive, thus, the parabola is opening upwards, and the directrix is "outside" the parabola, so is below the vertex
that puts the directrix 2 units below 0,0
y = -2
a) 
The average speed is equal to the ratio between the total distance (
and the total time taken (
):

the distance travelled by the trucker in the first 3 hour can be written as the time multiplied by the velocity:

So the total distance is

The total time is equal to the first 3 hours + the time taken to cover the following 20 miles in the city:

So, the equation can be rewritten as:

b) 0.50 h (half a hour)
Since we know the value of the average speed,
, we can substitute it into the previous equation to find the value of
, the time the trucker drove in the city:
