Answer:
b. sqrt(a+2)^2+(b-5)^2+(c-6)^2
Step-by-step explanation:
Use distance formula
sqrt (a-(-2)^2 + (b-5)^2 + (c-6) ^2
sqrt (a+2)^2 +(b+5)^2 + (c-6)^2

Answer:
The values of y such that the barn is 70 yards from the well are y=76 or y=-64
Step-by-step explanation:
Distance in the Plane
Given two points in a rectangular system of coordinates (a,b) and (c,d) the distance measured between them is calculated with the formula
The barn is located at (4,6) and the well is located at (4,y). The value of y must be calculated in such a way the distance between the barn and the well is 70 yards. Thus, the equation to solve is
Operating
When taking the square root we must be careful for it has two signs:
Rearranging
which yields to these solutions
And also
The values of y such that the barn is 70 yards from the well are y=76 yards or y=-64 yards

Answer:
-120/119
Step-by-step explanation:
cos α = -5/13 = adj/hyp
using Pythagoras theorem
hypotenuse ² = opposite² + adjacent ²
13² =opp²+ (-5)²
169 = opp² + 25
169-25 = 144 = opp²
opp = √144 = 12
sinα = opp/hyp = -12/13
sin β = -12/13
tan(α+β) = (tanα + tanβ)/ (1-tanαtanβ)
cos α = -5/13
sinα = 12/13
tanα= sinα/cosα = 12/13 / -5/13 = 12/-5 = -12/5
sin β = -12/13
cos β = 5/13
tan β = sinβ/cosβ = -12/13 / 5/13 = -12/5
tan(α+β) = (tanα + tanβ)/ (1-tanαtanβ)
tanα = -12/5
tanβ= -12/5
tan(α+β) = (tanα + tanβ)/ (1-tanαtanβ) = (-12/5+(-12/5))/(1-(-12/5)(-12/5))
(-12/5+(-12/5)) = -12-12/5 = -24/5
(1-(-12/5)(-12/5)) = 1-(144/25) = (25-144)/25 = 119/25
tan(α+β) = (tanα + tanβ)/ (1-tanαtanβ) = (-12/5+(-12/5))/(1-(-12/5)(-12/5)) =-24/5/119/25 = -24/5 x 25/119 = -24x5/119 = -120/119
