Step-by-step explanation:
(2ab-7a-4) - (7ab-4)
= 2ab - 7a - 4 - 7ab +4
(-) × (-) = (+)
(-) × (-) = (+)-(-4)= +4
then 4 will be cancelled
= 2ab - 7ab - 7a
= -5ab -7a
PEMDAS means we do exponents before we multiply.
10 ^ 7 = 10,000,000
(10 * 10 * 10 * 10 * 10 * 10 * 10)
5.8 * 10,000,000
= 58,000,000

Answer:
1. B. a=14, b=2
2. D. a=1, b=1.4
Step-by-step explanation:
The exponential growth function can be represented as

where b is the growth factor.
1. When the function has equation

then

The initial amount is the value of the function at x=0:

The growth factor is b=2
2. When the function has equation

then

The initial amount is the value of the function at t=0:

The growth factor is b=1.4
