Answer:
51
Step-by-step explanation:
Answer:
80
Step-by-step explanation:
180=(50+50)+x
180 = 100+x
x=80
There are 14 times in the table. Add up all 14 times, and divide the sum by 14. The result is the "mean 100-meter sprint time," assuming that you've rounded this off to the nearest tenth of a second.
Answer:
18,000,000
Step-by-step explanation:
h
lol, easy 00 times 60000 is 18,000,000
Y = -4(x - 2)² + 4
This equation is in vertex form.
y = a(x - h)² + k
(h,k) is the vertex.
(h, k) = (2, 4)
axis of symmetry x = 2
So it will be the graph with a point at (2, 4).
Also remember that it opens downward because the a is negative.
The graph is the upper right one.
vertex is (2, 4).
x = 2
