First you have to find out the cost of the ticket. To do so you have to Divide 15 and 6. Which equals $2.50. So each ticket is $2.50 dollars. Now you have to multiple 2.50 times 9. which equals 22.5. So your total answer is $22.50 dollars
Answer: Domain (-∞,∞) ; range: (0,∞)
Step-by-step explanation:
1. The exponential functions with the form 
has domain of all real numbers, becaure there is no values in the set of real number for which the value of 
is not define. When approches to ∞, the function approches to ∞.
2. When approches to -∞, the function approches to 0 but never touches it. This means that 
is always greater than zero (
). Therefore, the range of the function is (0,∞).
Answer:
A. 0.69
Step-by-step explanation:
We need to use cosine theorem:
c²=a²+b² - 2ab* cos(θ)
c=8, a=7, b=11
8² = 7²+11² - 2*7*11 *cos(θ)
64 = 49 + 121 - 154*cos(θ)
64 - 170 = - 154*cos(θ)
- 106/ (- 154) = cos(θ)
cos(θ) = 0.69
First you would have to simply the expression by distributing.
10xy-4xy-8x²y
the only common terms are xy, so your final answer is 6xy-8x²y.
