Answer:
intercept 
line 
Step-by-step explanation:
Let
is the required line.
<u>Slope of perpendicular lines :</u> If
and
be slope of two perpendicular lines. Them 
is perpendicular to 
the slope of
is 

Hence eqn is 
This equation passes through 

so the line is 
<u>y-intercept :</u>
Substitute 

Answer:

Step-by-step explanation:
<u>Constant Speed Motion
</u>
When the object travels the same distances in the same period of time, the speed is constant and is can be calculated as

where x is the distance and t is the time
There are two canoes traveling at speeds v1 and v2. One of them has twice the speed as the other. Let's say

When t hours have passed, the canoes have traveled x1 and x2 respectively.


Since

Then

The distance between them is


That distance is known and equals 11.25 miles, thus

Solving for v1 and using t=4.5 hours




Answer:

The sear tower is
times higher than the sears tower model
Step-by-step explanation:
we know that
The ratio of the height of the model to the height of the actual sears tower is equal to the scale factor
Let
z------> the scale factor
x-------> the height of the model
y-------> the height of the actual
so

we have


substitute

simplify

Remember that

so
