Answer:
It would be the first option: Last week, Rosemary walked at a faster pace.
Step-by-step explanation:
Last week, the speed was d=3h, as for this week, her speed was d=2.5h.
No one knows how many hours she walked this week so we cannot say that she walked a greater distance.
Answer:
C
Step-by-step explanation:
y= 60(2)+10
y=130
y=65(2)
y=130
The slope of the graph shows the rate of change, or, in this case, the rate of depreciation, which you are told is $100 per year. So, depending upon the units used in your graph, the slope will be 100/1, and since it is a decrease as the years increase, it will have a negative slope, i.e. -100/1.
Or, if you had drawn your graph with units of $100 dollars on the y-axis, then you might say that the slope was -1 / 1.
The corresponding formula would of course be
y = 600 - 100t
where y = value after t years, and (if you are into calculus) differentiating would give you
slope = dy/dt = -100

X-1 + x + x+1 = 42
3x = 42
x = 14
the numbers are 13 14 and 15
Answer:
3854ft
Step-by-step explanation:
By assuming that the cable is not doubled.
in order to find the length of the base of the mountain
tan74°=3400/x
x= 3400/tan74°
x≈ 975ft
Therefore, the length of the cable equals to
=
length≈ 3854ft
Thus, the shortest length of cable needed is 3854ft
