Answer: slope is 1
equation: 1x-2 or x-2
I hope this is good enough:
Answer:
Similar but not congruent
Step-by-step explanation:
They look to be the same shape, but they aren't the same exact size so they cant be congruent. To be congruent they would have to be the same size and shape, but they are only the same shape, different sizes.
Answer:
13.5
Step-by-step explanation:
Average rate of change=(f(2)-f(1))/1=-18/2^2-(-18))=13.5
The axis of symmetry is X=-2
The vertex is (-2,4)
The maximum is 4
There is no minimum as the maximum is also the vertex of the parabola.
The zeros are (-4,0) and (0,0) or just 0 and -4
The domain is all real numbers from negative infinity to positive infinity
The range contains all real numbers less than or equal to 4 :)
A wheel with a 20 in diameter has a circumference of 2π*(20 in) = 40π in.
For every 40π in traveled, a wheel makes one complete revolution, or turns an angle of 2π rad.
We need to convert from in to mi: there are 12 in to 1 ft, and 5280 ft to 1 mi, and so there are 12*5280 = 63,360 in to 1 mi.
We also need to convert h to min: there are 60 min to 1 h.
So we have an angular speed of
(45 mi/h) * ((2π)/(40π) rad/in) * (63,360 in/mi) * (1/60 h/min) = 2376 rad/min
As mentioned before, there are 2π rad to 1 rev, so
(2376 rad/min) * (1/(2π) rev/rad) ≈ 378.152 rev/min
(where rev/min is equivalent to rpm)
