sin(a+b) = sinacosb + cosasinb
sin(a-b) = sinacosb - cosasinb
adding we get sin(a+b) + sin(a-b) = 2sinaccosb
so sinacosb = 1/2sin(a+b) + sin(a-b)
Answer: Sin a
Axis of symmetry (blue line): x= -2
X intercepts (green dots): (-3,0), (-1,0)
Y intercept (black dot): (0,9)
Vertex (red dot): (-2,-3)
If there is both multiplication and division, you go from left to right.
24/6=4
4x2=8
8 is the answer.
Answer:
100 + (5X) = -2X
Step-by-step explanation:
Since the club with an occupancy of 100 will sell out at $ 25 per ticket, and if the owner decides to increase the price by $ 5, then 2 less tickets will be sold, to determine the revenue function if X is the number of $ 5 increases the following calculation must be performed:
100 + (5X) = -2X
So, for example, if the price were increased by $ 15, the equation would apply as follows:
15/5 = 3
100 + (5x3) = -2 x 3
100 + 15 = -6
115 = -6
