The tangent meets the radius at a right angle.
We use (the converse of) the Pythagorean Theorem to check:
Not a right triangle
Answer: FALSE
Answer:
a) -3 gallons per hour
b) y = -3x +14
Step-by-step explanation:
Rate of change is computed by dividing the amount of change by the interval over which it occurred.
<h3>a)</h3>
Here the amount of gas decreased from 14 to 2 gallons, so a decrease of 14-2 = 12 gallons. That occurred over a 4-hour period, so the rate of change is (-12 gallons)/(4 hours) = -3 gallons/hour.
__
<h3>b)</h3>
The initial amount was 14 gallons, so the equation for the line describing remaining gas will be ...
y = -3x +14 . . . . gas in the tank after x hours
Answer:
using the given points substitute it into the equation y=mx+c
therefore
y=4
m=-2/3
X=6
c=?
so we should c=intercept
Step-by-step explanation:
y=mx+c
4=-2/3(6)+c
4=-4+c
c=4+4=8
therefore equation of the graph is y=-2/3X+8
Answer:
The number of cars passing or the people arriving during lunch hour will be around 220
Step-by-step explanation:
First we find the for ten minutes period from given data:
Average Cars in 10 minutes = (18+38+87+16+56+5)/6
Average Cars minutes = 36.67
Now, for average cars in 1 hr, we must multiply this value by 6. As, 10 minutes multiplied by 6 equals 1 hr.
Average cars in an hour = 36.67*6
<u>Average Cars in an hour = 220</u>
Hence, the number of cars or people arriving during lunch hour will also be equal to average number of cars arriving during an hour.
