The first thing you should know for this case is how many years there are from 1997 to 2014.
The number of years is:
x = 2014-1997 = 17
Then, you must replace this value in the given equation:
y = 1.28e ^ 1.31x
y = 1.28 * e ^ (1.31 * (17))
y = 6011018736
answer:
the number of camera phones shipped in millions in 2014 is
y = 6011018736
Answer: x-intercept
<u>Step-by-step explanation:</u>
NOTES
1) Parabolic motion is represented by the equation:
h(t) = -9.8t² + vt + h (in meters per second²), v is velocity
or
h(t) = -32t² + vt + h (in feet per second²), v is velocity
2) The x-axis is time (in seconds) & the y-axis is height (in meters or feet).
Since you want to know what time the object hit the ground, h = 0
Therefore, you are looking for the zero of the equation, which is on the x-axis, thus is the x-intercept.
Step-by-step explanation:
k(a) =3a+2
k(2)=3*2+2
k(2)=6+2
k(2)=8
