Answer:
y = -2x+4
Exp:
Slope (m) =
ΔY
ΔX
=
-2
1
= -2
θ =
arctan( ΔY ) + 360°
ΔX
= 296.56505117708°
ΔX = 2 – 1 = 1
ΔY = 0 – 2 = -2
Distance (d) = √ΔX2 + ΔY2 = √5 = 2.2360679774998
Equation of the line:
y = -2x + 4
When x=0, y = 4
When y=0, x = 2
Answer:$724
Step-by-step explanation: so in the first month they charge 149+ 25 which equals 174. then you 25x11 which gets you 275.then you add those 2 and get 449. then you 449 plus 275 and get 724.
Answer:
Bob's dog should be given 216 mg of medicine.
Step-by-step explanation:
Given that:
Weight of dog = 30 lbs
We know that:
1 lb = 0.45 kg
30 lbs = 0.45 * 30 kg
30 lbs = 13.5 kg
Medicine for each kilogram of weight = 16 mg
1 kilogram = 16 mg
13.5 kg = 16 * 13.5 mg
13.5 kg = 216 mg
Hence,
Bob's dog should be given 216 mg of medicine.
Answer:
64.5°
Step-by-step explanation:
angle of elevation is the angle from the point where the shadow ends. this create a right angle triangle. using tan, you can find the angle.
tan theta = opposite/adjacent
angle = tan^-1(42/20)
angle = 64.5°
Answer:
x = 13
Step-by-step explanation:
3x + 2x + 5 = 60
5x + 5 = 60
5x = 65
x = 13
