Answer: 895 phones
Step-by-step explanation:
Given that :
The function : y = 1.28e^1.31x ; is used to model the number of camera phones shipped since 1997
y = number of camera phones ; x = number of years since 1997
The number of camera phones shipped in the year 2002 can be obtained thus ;
x = 2002 - 1997 = 5 years
y = 1.28e^(1.31 * 5)
y = 1.28e^6.55
y = 1.28(699.24417)
y = 895.03254
y = 895 phones
Answer:
The coordinates of point B are (3,-2)
Step-by-step explanation:
we know that
The rule of the reflection of a point across the y-axis is given by
(x,y) -----> (-x,y)
so
Applying this rule to the point A(-3,-2)
A(-3,-2) --------> B(3,-2)
therefore
The coordinates of point B are (3,-2)
Answer:
C.) or the third one
Step-by-step explanation:
Each input has one output.
Answer: 1- function 1 has the greater rate of change but function 2 has the greater y-intercept
Step-by-step explanation:
We know that function 1 is:
y = f₁(x) = 0.75*x - 1
And for the second linear equation we can see that it passes through the points (-3, -1) and (0,1)
Then the slope is:
a = (1 - (-1))/(0 - (-3)) = 2/3
then the equation is something like:
y = f₂(x) = (2/3)*x + b
To find the value of b, we use the fact that when x = 0, we have y = 1.
Then:
1 = (2/3)*0 + b
1 = b
Then the equation for function 2 is:
f₂(x) = (2/3)*x + 1
So the two equations are:
f₁(x) = 0.75*x - 1
f₂(x) = (2/3)*x + 1
Where we can see that function 1 has a greater slope (rate of change) and function two has a greater y-intercept.
Then the correct option is
(1- function 1 has the greater rate of change but function 2 has the greater y-intercept)
