First convert them to vertex form
first one is y = 2(x + 0.75)^2 - 6.125
2nd is y = -2(x - 0.75)^2 - 3.875
the -2 will cause a reflection of the first equation in the x axis . then a translation down of 6.125 + 3.875 = 10 units , followed by
a translation of -0.75-0.75 = -1.5 units to the right = 1.5
Given:
f(x) = 620e^7.8x
The standard equation for an exponential function is f(x) = Aoe^bx
where Ao is the initial amount
b is the growth factor
so, in this case, the initial amount is 620 and the growth factor is 7.8

The length of the hypotenuse is 68 km.
To figure out percents you can set it up like:
80/160 = x%/100%
Then cross multiply:
160x = 8000; now divide each side by 160 to isolate x, and you get x = 50%
The answer makes sense, because 80 is half (or 50%) of 160
Answer:
The answer is (2,1)
