Andrew can reach a maximum of 
high up the wall.
The right-angled triangle formed can be solved using the 
ratio. that is
where 
is the distance from the foot of the wall to the tip of the ladder where it rests on the wall. Substituting, and solving for , we get
Since Andrew can reach an extra 
above the point where the ladder rests against the wall, the maximum height Andrew can paint is

Answer:
Step-by-step explanation:
First you need to use your information to set up a proportion. (put your parts over the wholes and a variable in the blank spot.
<u>part </u> <u> part</u>
whole whole
<u>2 </u> <u>6</u>
x 150
Now you use the butterfly method, cross multiply the numerator and denominator and then divide that answer by the remaining numerator or denominator. This will give you the missing value for your variable.
150 x 2 = 300 300 ÷ 6 = 50
Answer: 30 mph is the answer.
Step-by-step explanation:
s = 3 miles
t = 6 minutes
so,
60 minute = 1 hour
1 minute = 1/60 hour
6 minutes = 1/60 * 6 = 0.1 hour
so
average speed = s/t
= 3/0.1 = 30 mph
Answer:
Step-by-step explanation:
See the attached graph.
The points (0,3) and (1,1) are on the graph of the exponential function.
Let the function be 
....... (1)
Now, satisfying the point (0,3) we get from the equation (1),
Therefore, the initial value of the function is a = 3
Hence, the equation becomes 
......... (2)
Now, satisfying the point (1,1) we get from equation (2)
⇒ b = 1/3
So, the final equation becomes (Answer)
Answer:
The answer is -x
