The focus is above the directrix, so the parabola opens upward—its vertical scale factor is positive (+1/12). The line of symmetry is x=-5, so the vertex form of the equation will have the factor (x -(-5))² = (x+5)². The choice that meets both these requirements is
D. f(x) = (1/12)(x + 5)² + 2
The answer is obvious its the answer to anything else 42<span />
Answer:
Step-by-step explanation:
x_0=0
x_1 = $40
so delta change is $40. Now we can write the equation as
y = 40x, where y is the total saving account amount.
So after the 6th deposit, her total saving is $240.
y = 40(6) => 240
Answer:
B. 48x - 56
Step-by-step explanation:
The total number of produced details increased by 6.4%
suppose the starting number was x.
suppose x=100
100 +12%= 112
112-5%=106.4
106.4-100=6.4
6.4%
