Answer:
Step-by-step explanation:
Let the exponential function be,
Here, C = cost of the car
t = Duration or period in years
From the given table,
Two points representing cost of the car and time are (10000, 0) and (8520, 1),
For (10000, 0),
a = 10000
For (8520, 1)
8520 =
b = 0.8520
Therefore, exponential equation will be,
Answer:
C)One of the vertices is (-10,2)
Step-by-step explanation:
Given the hyperbola:
The standard equation for a hyperbola with a horizontal transverse axis is:
where the center is at (h, k).
For our given hyperbola, the center (h,k)=(-5,2)
Now:
Since the center is at (-5,2), its foci (-c,0) and (c,0) are:
(-5-5,2) and (-5+5,2)= (-10,2) and (0,2)
Similarly, since the center is at (-5,2), its vertices, (-a,0) and (a,0) are:
(-5-4,2) and (-5+4,2)= (−9,2), (−1,2).
Therefore, the odd option is C.
Answer:
The number of hits is
Step-by-step explanation:
From the question we are told that
The ratio of the number of hits to the number of chances is equivalent to the batting average
The number of chances is j = 65 + 10 = 75
The number of hit so far is n = 25
Generally the batting average can be represented mathematically as
Here k is the number of additional hits Kyle need to get in order to obtain the batting average of 0.40 or more
So
=>
Hence the number of hits for Kyle to get a batting average of 0.400 or greater by the end of the season is
=>
=>
