Given that the concentration has been modeled by the formula:
C(t)=50t/(t^2+25)
where:
t is time in hours.
The concentration after 5 hours will be given by:
t= 5 hours
plugging the value in the equation we get:
C(5)=(50(5))/(5^2+25)
simplifying the above we get:
C(5)=250/(50)=5 mg/dl
Answer: 5 mg/dl
Answer:
Option 2.
Step-by-step explanation:
The antifreeze claims to protect between -30 C and 130 C. The inequality should be this: 
You can replace C with the Fahrenheit formula: C=
So, the inequality becomes 
Answer:
Either 43 or 88
Step-by-step explanation:
45/3 = 15 (one witch)
21/3 = 7 (one broom)
12/3 = 4 (one spoon)
PEMDAS:
Equation: 15 + 7 x 4
if there are parenthesis and the equation looks like:
(15 + 7) x 4
the <u>answer is 88</u>.
if there is NOT parenthesis and the equation looks like:
15 + 7 x 4
the <u>answer is 43</u>.
