Answer: Option C. $13.90
Solution:
Approximate cost to go on a safari ($): y
Number of years since it opened in 2005: x
y=3.648*1.182^x
Cost in year 2013: y=?
Year 2013→x=2013-2005→x=8
y=3.648*1.182^8
y=3.648*3.810130162
y=13.89935483
y=13.90
The best estimate for the cost of a vehicle to drive through the safari in 2013 is $13.90
Answer: The answer is in the 1st image.
Explanation: The explanation is in the 2nd image.
Answer:
Center is (7,-6)
Our radius is 4
Step-by-step explanation:
Subtract 69 to both sides
Complete the square of the x terms and y terms.
(To complete the square divide the coefficient by 2 and square it).
Add those terms to the full equation. Add 36 and 49 to the right side as well
Simplify the x and y terms into a binomial.
Set the left side equal to zero separately to find the center and take the square root of the right side to find the radius.
So our center is (-7,6)
Our radius is 4.
