Answer:
y = - 3x + 6
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange x - 3y = 5 into this form
Subtract x from both sides
- 3y = - x + 5 ( divide all terms by - 3 )
y = x -
← in slope- intercept form
with slope m =
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
= - 3
Note the line crosses the y- axis at (0, 6) ⇒ c = 6
y = - 3x + 6 ← equation of perpendicular line
The penguin will walk 75.15 feet in 45 sec
It will take the penguin 26.95 sec to walk 45 feet
Step-by-step explanation:
Given
Distance = d = 10 feet
Time = t = 6 sec
First of all we have to calculate speed
Let s be the speed, then
Now,
How far does the penguin walk in 45 seconds?
Here we know the speed and the time
So,
s=1.67 ft per sec
t = 45 sec
So,
How long does it take the penguin to walk 45 feet?
Here we know
d =45 feet
and
Speed =s =1.67 ft per sec
So,
The penguin will walk 75.15 feet in 45 sec
It will take the penguin 26.95 sec to walk 45 feet
