<span>Distance formula in three dimensions for the distance between the points
is:<span> </span>Therefore the length of the diagonal is the distance between the points P(1,1,2) and Q(3,4,5) :</span>
Answer:
The answer to your question is:
a) 8.2 mi
b) 4.1 mi
c) 4.7 mi
Step-by-step explanation:
For 30°
sin Ф = opposite leg / hypotenuse
hypotenuse = opposite leg / sin 30
hypotenuse = 4.1 / sin 30 = 4.1 / 0.5
hypotenuse = 8.2 mi
For 90°
d must be 4.1 mi because is over the observer at this angle
For 120°
distance = opposite leg / sin 60
distance = 4.1 / √3/2
= 4.71 mi

Ok, so on the first day she finds one, the second she finds two, the third four, the fourth eight, the fifth sixteen, the sixth thirty two, and the seventh sixty four.
The answer is 64
Answer:
84.25
Step-by-step explanation:
first do the powers 2 to the 3rd power 8 3.5 to the second power 12.25 8 x 10 80 - 8 = 72 + 12.25 = 84.25
If you would like to find the rational roots of x^4 + 8 * x^3 + 7 * x^2 - 40 * x - 60 = 0, you can do this using the following steps:
x^4 + 8 * x^3 + 7 * x^2 - 40 * x - 60 = 0
(x^2 - 5) * (x^2 + 8 * x + 12) = 0
(x^2 - 5) * (x + 6) * (x + 2) = 0
1. x = - sqrt(5)
2. x = sqrt(5)
3. x = - 6
4. x = - 2
The correct result would be -6 and -2.
