Answer:

26. B(t) = 500·1.075^t; B(6) ≈ $772

27. G(t) = 70·0.72^t; G(3) ≈ 26 g

Step-by-step explanation:

The equation with the plus sign is used when the value is increasing. The minus sign is used when the value is decreasing. The 'a' in each equation is the initial value.

26. B(t) = 500·1.075^t

B(6) = 771.65

The balance after 6 years is about $772.

27. G(t) = 70·0.72^t

G(3) = 26.127

About 26 grams are left after 3 days.

For each quadratic function, find the domain range vertex and axis of symmetry y=(x-1) squared +1

Arada [10]

$y=(x-1)^2 +1 \\ \\ For \ the \ quadratic \ function \\ \\ f(x) =a(x-h)^2+k \\ \\ where \ a, \ h \ and \ k \ are \ real \ numbers \ with \ a \neq 0 , \\ \\ the \ vertex \ is \ (h,k) =(1,1) \\ \\ a \ symmetry \ about \ the \ vertical \ line \ x = h \\ \\ x= 1$
