Hi! Your answer is 13.
All you have to do is divide 52 by 4. When you do this, you will find how many laps they walked per hour.
(They walked 52 laps in 4 hours)
52 / 4 = 13
They walked 13 laps in one hour.
Hope this helped!
The answer is 3275/12=272.916666667/7.5=<span>36.3888888889</span>
X\6=12\9
multiply both sides by 6
x=12\9 x 6
x=8
Answer:
y = -1
Step-by-step explanation:
As we move from point (-5, -1)
to point (2, -1), x increases by 7 and y stays the same.
The slope of this line is thus m = [-1 - (-1)] / 7, or just m = 0.
This is a horizontal line. Its equation is y = -1.
Ln x + xe^y = 1
1/x + xf'(x)e^y + e^y = 0
f'(x) = (-e^y - 1/x)/xe^y
f'(1, 0) = (-e^0 - 1/1)/e^0 = (-1 - 1)/1 = -2
Let the required equation of tangent be y = mx + c, where y = 0, m = -2, x = 1
0 = -2(1) + c = -2 + c
c = 2
Therefore, required equation is y = -2x + 2
