135 divided by 9 is 15 so there's 15 people in each group and this people 15 people will watch each movie.
Answer:
B=0.10x+2
Step-by-step
sponsor b is paying .10 x 52 pins + $2. = 5.20 + 2 = 7.20
it isn’t the 2 times 52
it is not subtracting the money
and we have to consider the 52 pins as X
Recall that the vertex form of a quadratic function (or parabolic function) is equal to
Now, given that we have f(x) = x² + 14x + 40, to express f into its vertex form, we must first fill in the expression to form a perfect square.
One concept that we must remember when completing the square is that
(a + b)² = a² + 2ab + b²
So, to complete the square for (x² + 14x + ____), we have 2ab = 14 where a = 1. Thus, b = 14/2 = 7. Hence, the last term of the perfect square must equal to 7² = 49.
So, going back to the function, we have
Thus, we have derived the vertex form of the function.
Answer: f(x) = (x + 7)² - 9
24 because 12 times 2 is equal to 24
