Use Law of Cosines g^2 = f^2 + h^2 -2fhCosG f^2 = g^2 + h^2 -2ghCosF h^2 = f^2 + g^2 -2fgCosH
f^2 = 28^2 + 15^2 -2*28*15Cos87 28^2 = 31^2 + 15^2 -2*31*15CosG
f^2 = 784 + 225 - 43.96 784 = 961+225 - 930CosG
f^2 = 965.0378 784 - 1186 = -930CosG
f = 31 -402 = -930CosG Divide by -930
.432258 = CosG
Cos^-1(.432258) = G
G = 64 degrees
Angle H = 180 - 64 - 87 = 29 degrees
Side f = 31 Angle F = 87 degrees
Side g = 28 Angle G = 64 degrees
Side h = 15 Angle H =29 degrees
Answer:
0.55 mile / minute
Step-by-step explanation:
The average change of altitude per minute would simply be the ratio of distance descended over time. That is:
average change of altitude = distance / time
average change of altitude = 0.44 mile / 0.8 minutes
average change of altitude = 0.55 mile / minute
Answer:
a = 8 2/3.
Step-by-step explanation:
The y coordinate of the point is 5, andthe x coordinate is a so substituting for these in the given equation:
3a - 4(5) = 6
3a - 20 = 6
3a = 26
a = 26/3
= 8 2/3
Use the reciprocal method. the first term is really 4 divided by 3/4. which is also the same as 4 multiplied by 4/3. that number is 16/3 of course. you then find a common denominator between the 2 terms. 16/3 and 3/2 can both have the denominator 6. The first term gets changed to 32/6 and the second can be changed to 9/6 and when 32/6 - 9/6 is done, it comes out to 23/6
23/6
4/16 do not receive treatment
which is 25%
25% do not receive treatment
