Answer:
64.84 square cm
Step-by-step explanation:
two semicircles/a circle with 6cm diameter = 28.27 cm squared
two semicircles/a circle with 4cm diameter = 12.57 cm squared
28.27 + 12.57 + 24 = 64.84
Step-by-step explanation:
Answer:
12
Step-by-step explanation:
For these problems you should use the pythagorean theorem: a^2+b^2=c^2
In this case, 13=c and 5=a
so:
5^2+x^2=13^2
25+x^2=169
subtract 25 from both sides
x^2=144
√144=12
missing side=12
Answer:
0.00335
Step-by-step explanation:
Probability that one of the components works for x hours before failing is given by
f(x) = 2e⁻²ˣ
We can then find the probability that one of the components works for x = 4 hours before failing
f(x) = 2e⁻⁸ = 0.0006709253
Probability that the system works for 4 hours = probability that at least 1 of the components of the system works for 4 hours =
1 - (Probability that none of the components of the system works for 4 hours)
Probability that one of the components doesn't work for 4 hours = 1 - 0.000670925 = 0.9993290747
Probability that none of the 5 components work for 4 hours = (0.9993290747)⁵ = 0.9966498721
Probability that the system works for 4 hours = probability that at least 1 of the components of the system works for 4 hours
= 1 - (Probability that none of the components of the system works for 4 hours)
= 1 - 0.9966498721 = 0.0033501279

Answer:
y = -x +1
Step-by-step explanation:
p1 (-3,4)
p2 ( 3, -2)
line equation y = mx + b
The slope m equals
y = - x + b
from any point
-2 = -3 + b
b = 1
line equation = y = -x +1
