Answer:
Side = 12 cm, side = 5 cm, side = 8 cm
Step-by-step explanation:
In order to form a triangle with non-zero area, the sum of the shortest two sides must exceed the longest side.
This will be the case for {5, 8, 12}, but not for any of the others.
___
The side lengths {5, 8, 13} will form <em>a triangle with zero area</em>. This is acceptable according to one version of the triangle inequality (a+b≥c) but not according to the other version (a+b>c). Since you are apparently expected to find one "right answer", we assume the answer you want is the one shown above.
The flying drones are illustrations of the laws of cosines
Both flying drones would be 128.13 meters apart after 1 hour
<h3>How to determine the distance between them</h3>
For drone A, we have:
- Angle =120 degrees
- Speed = 80 mph
So, the distance after one hour is:
Distance = 80 m
The distance is calculated using:
Distance = Speed * Time
For drone B, we have:
- Angle = 320 degrees
- Speed = 50 mph
So, the distance after one hour is:
Distance = 50 m
The angle between them is calculated as:
This gives
Using the laws of cosine, the distance (d) between them after 1 hour is:
So, we have:
Evaluate the expression
Hence, both drones would be 128.13 meters apart after 1 hour

First you move. -x for +x
2y = 16 + x
y = 8 + 1/2 x
the answer is
y = 1/2x + 8
Answer:
2/3x^3+1/6x^2
Step-by-step explanation:
Answer:
a) μ =35.858KN
b) median cable strength =36.06KN
Step-by-step explanation:
Let X1, X2, X3, X4 represent the strength of the 4 wires.
We can find the median of the cable strength in minitab as:
Stat - Basic statistics- Display descriptive statistics-variable (C5) -statistics(median) - ok
Median cable strength is 36.06 KN
Therefore the estimate of the mean strength of the cable is 35.858 KN, and the estimate of the median cable strength is 36.06 KN.
