Answer:

f(-5)= 28

Step-by-step explanation:

The function is:

f(x)= x^2-2x-7

To find the answer put the value of -5 for all x's.

f(x)= x^2-2x-7

f(-5)=(-5)^2 - 2(-5)-7

f(-5)=25+10-7

f(-5)=35-7

f(-5)= 28 ...

Sarah takes 550 mg of an antibiotic. Every hour, her body breaks down 25% of the remaining drug. How much will be left after 12
hammer [34]

The amount of drugs that will be left after 12 hours is 17.42 mg provided Sarah takes 550 mg of an antibiotic every hour.

<h3>What is exponential decay?</h3>

Exponential decay can be described as a reduced amount of an original substance by a definite percentage over a period of time. It can be determined by using the formula:

\mathbf{y = a(1 - r)^t}

where;

  • y = total amount,          
  • a = initial amount = 550 mg
  • r = the growth rate = 0.25
  • t = number of growth periods = 12 hours

\mathbf{y = 550(1 - 0.25)^{12}}

y = 17.42 mg

Therefore, we can conclude that the amount of drugs that will be left after 12 hours is 17.42 mg.

Becca hikes 9/10 mile in 5/3 hour.
Artist 52 [7]

Answer:

(9/10 mile)/(5/3 hour) = 27/50 miles/hour

Step-by-step explanation:

If you are looking for the speed, then speed = distance/time

speed = (9/10 mile)/(5/3 hour)

speed = 9/10 ÷ 5/3 miles/hour

speed = 9/10 × 3/5 miles/hour

speed = 27/50 miles/hour
