Step-by-step explanation:
Velocity = Displacement/Time
a) Velocity in m/s = 3600m/6s
= 600m/s
b) (Converting m into km)
1000m = 1km
3600m = ?
3600/1000 = 3.6km
(Converting secs to hours)
1mins = 60secs
60mins = ?
60 * 60 = 3600 secs
This means there are 3600 secs in 1 hour
3600secs = 1hour
6.0 secs = ?
6.0/3600 = 0.00167 hours (approximately)
Velocity in km/h = 3.6km/0.00167h
= 2155.69km/h (approximately)
In summary...
a) 600m/s
b) 2155.69km/h

Answer:
3.75 cm
Step-by-step explanation:
Corresponding sides are proportional.
CD/BC = BC/AB
CD = (BC)²/AB . . . . . multiply by BC
CD = (6 cm)²/(9.6 cm) = (36/9.6) cm
CD = 3.75 cm
Answer:
Part 1) Slope-intercept form
Part 2) The slope of 2.20 tells me the rate per mile and the y-intercept of 2.50 tells me the flat fee
Step-by-step explanation:
Part 1) we know that
The linear equation in slope intercept form is equal to

where
m is the slope or unit rate
b is the y-intercept or initial value
In this problem we have

This is a linear equation in slope intercept form
where


Part 2) we have that
x -----> represent the number of miles
y ----> represent the total charge in dollars
The slope is
---> unit rate
The y-intercept is
----> initial value or flat fee
therefore
The slope of 2.20 tells me the rate per mile and the y-intercept of 2.50 tells me the flat fee

Step-by-step explanation:</h2>
The graph of this parabola is shown below. From this graph we know that:
VERTEX:

DIRECTIX:
Since the vertex lies on the origin and the parabola opens upward, then the standard form of this parabola is:

So:

Then the directrix is:
