The correct answer is -308
Answer: maximum "safe" Force = 415.58 N
Step-by-step explanation:
<u>Length = 1.2 m</u>
lower bound is 1.15 (because it rounds up to 1.2)
upper bound is 1.24 (because it rounds down to 1.2)
<em>Note: 1.25 would round up to 1.3</em>
<u>width = 2.5 m</u>
lower bound is 2.45 (because it rounds up to 2.5)
upper bound is 2.54 (because it rounds down to 2.5)
<em>Note: 2.55 would round up to 2.6</em>
<u>Pressure = 150 N/m²</u>
lower bound is 147.5 (because it rounds up to 150)
upper bound is 152.4 (because it rounds down to 150)
<em>Note: 152.5 would round up to 155</em>
<u>Max "safe" Force means minimum Area and minimum Pressure (lower bounds)</u>
Force = Area x Pressure
= length x width x Pressure
= 1.15 x 2.45 x 147.5
= 415.58
Answer:
(x+8)² + (y+9)² = 100
Step-by-step explanation:
The equation for a circle on a graph is
(x - a)² + (y - b)² = r²
r represents the radius
a represents the x displacement of the circle's center.
b represents the y displacement of the circle's center.
Distance (s) = Velocity (v) x time (t)
if v = 8 kmh, t=5hr
s= 40 km covered each day
total distance = 4108.72km
4108.72/40 = 102.7
Hence it would take Davis 103 day to run from San Francisco to Albany.
300=(1/6*7/8)x
300=7/48x
300*48=7x
14400=7x
2057=x
So the answer is B
Hope this helps :)
