The amount of medicine in the bloodstream decreases by 25% each hour.
<h3>Exponential equation</h3>
The standard exponential equation is expressed as:
y = ab^x
a is the initial amount
b is the rate
If b < 1, hence there is a declince
Given the expoenentia equation A(h)=600(0.75)^h,
b = 1 - r = 0.75
r = 1 - 0.75
r = 0.25
This shows that the amount of medicine in the bloodstream decreases by 25% each hour.

Answer:
b) 280+5(-5)+(-42)+2(75)+(-200)
Step-by-step explanation:
had a balance of 280= 280
each day from monday to friday she payed $5 parking= 5(-5), because she payed(lost) $5 for five days straight, so you multiply them.
she wrote a $42 check= -42, because she spent more money, so she is losing money.
she made 2 deposits of $75= 2(75), because deposit means adding money, so she added $75 two different times.
she withdrew $200= -200, she took out $200.
Your answer is gonna be the second one!
Mode = 2

Answer: y = 57°
Explanation: 180-114 = 66°
A triangle has a total of 180° so 180-66 = 114
114 / 2 = 57° (because angles y and y have the same value)
