The equation for speed is:
The student ran 100 meters in 11 seconds. Our distance is 100 meters and our time is 11 seconds.
When we solve we get the following:
I am guessing since you were given the unit conversion of 1 mile = 1609 meters, you need to answer in miles per hour. If you do, you will need to use dimensional analysis:
All of the units except miles and hour cancel out, which makes this problem valid. Your answer in mph (mi/hr) would be:
20.34 miles per hour

Answer: g(x) = (-2/3)x^2</h3>
=====================================================
Explanation:
The blue parent function has a positive coefficient of 1. The purple g(x) function is a reflection of f(x) over the x axis, so everything is now negative. The coefficient must be negative as well.
But the answer is simply not g(x) = -x^2 because plugging x = 3 does not lead to y = -6 as the point (3,-6) shows.
Let's say the coefficient is k for now. So we have y = kx^2
Plug in x = 3 and y = -6. Solve for k
y = kx^2
-6 = k(3)^2
-6 = k*9
9k = -6
k = -6/9
k = -2/3
So we update y = kx^2 into y = (-2/3)x^2
Meaning that g(x) = (-2/3)x^2 is the equation of the purple curve.
Plug x = 3 into g(x) to find that
g(x) = (-2/3)x^2
g(3) = (-2/3)(3)^2
g(3) = (-2/3)(9)
g(3) = -6
which is the output we want, so this confirms we have the correct coefficient.
Answer:
D
Step-by-step explanation:
because you are looking for an intercept and an intercept is a square equation which when divided by 4 takes a slope. WHich then D works to make the slope
