Since it has a negative exponent, the equation
is showing exponential decay. The graph will decrease.
In order to find the percent of change, we need to review our exponent properties. The product property tells us that when we raise a power to a power, we multiply the exponents. This means we can view our exponent of -2x as the product of two exponents, -2 and x. This would look like
. We know that negative number exponents tell us to "flip" sides of the fraction, so that tells us that 4⁻² = 1/4² = 1/16. We can then rewrite our equation as
Exponential decay is in the form y = a(1-b)ˣ. From our equation, a = 1. We know that 1-b = 1/16; this means that b must be 15/16. Thus our percent of decrease would be 15/16 = 0.9375 = 93.75%.
Answer:
5/16
Step-by-step explanation:
There are a total of 16 different outcomes because 2*2*2*2 = 16.
There are 5 different ways for him to get 3 or more heads:
HHHT
HHTH
HTHH
THHH
HHHH
Therefore the probability is 5/16
Answer:
21 + 5 is the the same thing.
Step-by-step explanation:
9514 1404 393
Answer:
- interest: $353.38
- total: $4978.38
Step-by-step explanation:
The equation for calculating the balance in an account earning compound interest is ...
A = P(1 +r)^t
where r is the annual rate and t is the number of years.
For Sam's account, the balance after 2 years is ...
A = $4625(1 +0.0375)^2 = $4978.38
The interest is the amount in excess of the deposited amount:
$4978.38 -4525.00 = $353.38
Sam's interest was $353.38, giving him a total of $4978.38.
