Answer: vertex (-1, 0) axis of symmetry -> x = -1
Step-by-step explanation:
f(x) =
to find the vertex do
x+1 = 0
to find the x value
x = -1
plug -1 into the equation
f(-1) =
f(-1) = 3(0)
f(-1) = 0
Therefore, the vertex is (-1, 0)
The axis of symmetry is
x = -1
because that is where the lowest x value is
Answer:
The value at the end of year 2 is $4400.
Step-by-step explanation:
The best approach here is to determine the expression for the line depreciation and then calculate the depreciation value at x = 2 years.
A line is given by
where m is the slope and b the bias (aka y-intercept). You can determine both directly from what is given. The slope is change in y divided by change in x. We know that over 5 years the car loses (500-7000)=-6500 in value. So, the slope is m=-6500/5 (note the negative sign). At time 0, the y-intercept is 7000, since that is the initial value (at year 0). So our line function is fully identified:
and gives you the value of the car in any given year. To answer the question, we now plug in 2 as value of x:
Answer:
one example is
csc(30) = 1/sin(30)
here x = 30
