Answer:
the length of the shortest ladder is 11.41 feet
Step-by-step explanation:
The computation of the length of the shortest ladder is shown below:
AB^2 = AC^2 + BC^2
AB^2= (10)^2 + (5.5)^2
AB^2= 100 + 30.25
AB^2 = 130.25
AB = 11.41 feet
hence, the length of the shortest ladder is 11.41 feet
Answer:
8x - 7y = 56
Step-by-step explanation:
in order for lines to be parallel they need to have the same slope, the easiest way to determine if they have the same slope is to change the equations into y = mx + b form by solving for y and seeing where m=8/7
so 8x - 7y = 56
-7y = 56 - 8x
y = 56/-7 -8x/-7
y = -8 + 8/7 x
Answer:
0.45 second
Step-by-step explanation:
The number of seconds it takes a dropped object to fall d feet on Earth is given as:
E(d)=0.25√d
the number of seconds it takes a dropped object to fall d feet on the sun is given as:
S(d)=0.2⋅E(d)
Therefore
S(d)=0.2 × 0.25√d = 0.05√d
Given that it take a dropped object to fall 80 feet on the sun (i.e d = 80 feet), to calculate the time in seconds we use:
S(d) = 0.05√d
S(d) = 0.05 × √80 = 0.05 × 8.944 ≈ 0.45 s
It takes 0.45 second for a dropped object to fall 80 feet on the sun
