Answer:
183 miles to the nearest mile.
Step-by-step explanation:
Distance =Speed X Time
Distance of Truck B from point A=45 X2 =90 miles
Distance of Truck C from point A=55 X2 =110 miles
Angles between them, BAC=132°
We want to find the Distance BC denoted by a between the trucks.
Using Cosine Rule,
a²=b²+c²-2bcCos A
=90²+110²-(2X90X110XCos132°)
=33448.79
a=√33448.79
BC=182.89 miles
The distance between the trucks is 183 miles to the nearest mile.
Answer:
Greg worked more than 20 hours.
Step-by-step explanation:
Let's solve the inequality for so we know how many hours Greg worked:
Step 1. Subtract 25 from both sides of the inequality
Step 2. Divide both sides by 14
We can conclude that Greg worked more than 20 hours.
C=8πab
Divide both sides by 8πb
c/(8πb) = a
For graphing, the desmos graphing calculator is a big help :))
