-2x^2 - 5 is same shape as -2x^2 except that the whole graph is translated verticall downwards 5 units
Answer:
Step-by-step explanation:
(6^-7)^3 = 6^(-21) = (1/6)^21
Its B
Answer:
Jonathan's solution 
is correct.
Step-by-step explanation:
Given system of equations are:
Now
The graph of the linear equation 
cuts the y-axis at the point 
and x-axis at 
And the graph of the linear equation 
cuts the y-axis at the point 
and x-axis at 
And their point of intersection is
And this is Jonathan's solution.
We can see from graph that point of intersection is
In one revolution of the wheel, a point on the edge travels a distance equal to the circumference of the wheel.
The wheel has radius 1 ft, so its circumference is 2π (1 ft) = 2π ft.
Then the point has a linear speed of
(1/4 rev/s) * (2π ft/rev) = 2π/4 ft/s = π/2 ft/s
