0 Km , Displacement is distance from starting point. Not distance of Journey.
Answer:
so length of the fence is 250 feet
Explanation:
Given data
fencing (L) = 500 feet
enclose the garden = 3 sides
to find out
length of the fence
solution
we consider barn length x and width y
so we say x +2y = 500 ........1
we want to maximize length i.e xy = f
so we say
df/dx = ƛ × dL/dx
y = ƛ × 1
and
df/dy = ƛ × df/dy
x = ƛ × 2
from equation 1 we can say
2 ƛ + 2 ƛ = 500
so ƛ = 500/4 = 125
so that x = 2× 125 , y = 125
so x = 250 , y = 125
so length of the fence is 250 feet
Answer:
Their measured results are closer to the exact or true value. Hence, their measured value is considered to be more accurate.
Explanation:
Considering the situation described above, the accuracy of a measured value depicts how closely a measured value is to the accurate value.
Hence, since the students' measured values have very low percent differences, it shows the similarity of computations or estimates to the actual values, which in turn offers a smaller measurement error.
Therefore, their measured results are closer to the exact or true value, which implies that their measured value is considered to be more accurate.
The answer is 1.9 m
The ideal mechanical advantage (IMA) is the ratio of input distance (ID) to output distance (OD):
IMA = ID/OD
IMA = 2
ID = ramp length = 3.8 m
OD = height = ?
2 = 3.8m/OD
OD = 3.8/2
OD = 1.9 m
