Answer:
Step-by-step explanation:
n=n/2 +7
The equation is f(x) = 4x^2 - 4.
You can find this by using an equation with parenthesis that equal each of the zeros.
f(x) = (x - 1)(x + 1)
Now, this equation will not give us the vertex that we're looking for. So, we must add a constant being multiplied to the front of it.
f(x) = c(x - 1)(x + 1)
Now we can find the constant by putting our vertex into the equation and solving.
f(x) = c(x - 1)(x + 1)
-4 = c(0 - 1)(0 + 1)
-4 = c(-1)(1)
-4 = -1c
c = 4
Now we put the c into the original equation and solve for standard form.
f(x) = 4(x - 1)(x + 1)
f(x) = 4(x^2 - 1)
f(x) = 4x^2 - 4

Answer:
(x, y) = (10, 4)
Step-by-step explanation:
Opposite sides are the same length, so ...
ON = LM
6x -3 = 4x +17
2x = 20 . . . . . . . . add 3-4x
x = 10
__
OL = NM
x -5 = 3y -7
10 -5 + 7 = 3y . . . . . substitute x, add 7
12/3 = y = 4 . . . . . . simplify, divide by 3
The values of x and y are 10 and 4, respectively.
Answer:
B : a 20% increase in variable costs
Step-by-step explanation:
Here the industry is seeing a 20% increase in activity levels over the fourth quarter. Since, there has been an increase in activity levels the fixed cost would remain the same but the variable cost being variable would increase with increase in production activity in same proportion as the increase in production.
B : a 20% increase in variable costs
Step-by-step explanation:
The domain is all the x values that are included in a function.
Here the x values are from -11 to 9.
So the domain is [-11,9]
