Answer:
He will have paddled the canoe for 4 km.
a. The distance paddled out is equal to the distance paddled returning.
Step-by-step explanation:
Let <em>d </em>be the distance that Roger Waters paddled out.
Let <em>t </em>be the time for the travel he paddled out and <em>t' </em>be the time for returning.
Then from the formula 
,
<em>t </em>= 
and <em>t' </em>= 
Total time for the journey = 1 hour 30 minutes = 1.5 hours
So, <em>t</em> + <em>t'</em> = 1.5
3<em>d</em> = 6
<em>d</em> = 2 km
The total distance he will have paddled the canoe = 2<em>d</em> = 2(2) = 4 km.
Clearly, the distance he paddled out = the distance he returned.
Hence, the correct option is A.
Answer: y=7
Step-by-step explanation:
Use the vertex form to determine the values of
a
,
h
, and
k
and use these values to find the direction the parabola opens, vertex, focus, axis of symmetry, and directrix.
Direction: Opens Down
Vertex:

7x+36-2x. First thing you need to do is get the X on the other side of the equal side, which is add 2x to both sides then you should get 9x=36 then you would divide 9 and you should get <u><em>ANSWER:FOUR</em></u>

Hello!
Use the quadratic formula: 
First, let's convert our equation to standard form of a Quadratic: ax² + bx + c = 0
3x² = 80
3x² - 80 = 0
Note, thats the value of b will be 0, as there is no "bx"
Now, solve:
