Answer:
a = 1, b = 3, c = 1, d = 2, e = 6, and f = 8
Step-by-step explanation:
The given exponential functions are;
2ˣ, 3·2ˣ, and ![2^{3 \cdot x}](https://tex.z-dn.net/?f=2%5E%7B3%20%5Ccdot%20x%7D)
Let f(x) = 2ˣ, h(x) = 3·2ˣ, and g(x) = ![2^{3 \cdot x}](https://tex.z-dn.net/?f=2%5E%7B3%20%5Ccdot%20x%7D)
From the table for investigating the dilations of exponential function, we have;
a = f(0) = 2⁰ = 1
b = h(0) = 3·2⁰ = 3 × 1 = 3
c = g(0) =
= 2⁰ = 1
d = f(1) = 2¹ = 2
e = h(1) = 3·2¹ = 3 × 2 = 6
f = g(1) =
= 2³ = 8.
Answer:
42.5 square units.
Step-by-step explanation:
This is a trapezoid.
The area of a trapezoid can be found by a+b/2(h)
a=12
b=5
h=5
Plug in.
5+12/2(5)
17/2(5)
8.5(5)
42.5
