I’m pretty sure it’s D, if you count your boxes from the origin you go up four and over one so it would be 4x for slope
Answer:
(5, -9).
Step-by-step explanation:
The vertex if (h, k).
So for 6(x - 5)^2 - 9 the vertex is the point (5, -9).
R = speed in still water
r + c = speed with current
r - c = speed against current
3.5(r + c) = 70
r + c = 20
c = 20 - r
4(r + c) = distance from pier to pier
5(r - c) = distance from pier to pier
4(r + c) = 5(r - c)
4(r + 20 - r) = 5(r - 20 + r)
80 = 10r - 100
180 = 10r
18 = r
The speed in still water is 18 km/hour
The answer I got was: 12 + 3/5
Sorry I didn’t have that symbol thing on my phone so i had to use a slash.
Hope this helps :)
It is simply would be: √π
= √3.14
= 1.7728
In short, Your Answer would be: 1.7728
Hope this helps!
