Answer:
B, 3:1
Step-by-step explanation:
18:6 is 3:1 if you divide both sides by 6
Inorder to find the height, you miust plug in 0.05s for all times (t)
h(f) = -490t^2 + 75t + 12
h(f) = -490 • 0.05^2 + 75 • 0.05 + 12
Next follow PEMDAS from left to right.
(MD reversible, AS reversible)
(parentheses, exponents, multiply, divide, add, subtract)
parentheses~ nothing to simplify with parentheses
exponents~ h(f) = -490 • 0.0025 + 75 • 0.05 +12
multiply~ h(f) = -1.225 + 3.75 +12
divide~ nothing to simplify with division
add~ h(f) = 14.525
subtract~ nothing to simplify with subtraction
DON'T FORGET UNITS!
Answer: h(f) = 14.525 cm
Answer:
It is easy to calculate the half-life as 36 hours.
Looking at the graphic, we see that we will need the bottom formula
Ending Amount = Beginning Amount / 2^n
Where "n" is the number of half-lives which = 52 hours / 36 hours = 1.4444444 half-lives.
Ending Amount = 100 mg / 2^1.444444444
Ending Amount = 100 / 2.71258
Ending Amount = 36.74336230689
or rounding that off, it's about 36.743 milligrams

Answer:
600 cm
Step-by-step explanation:
Surface Area of a box: SA=2lw+2lh+2hw
Since a box has equal side lengths, <em>l </em>= 10, <em>w</em> = 10, and <em>h</em> = 10.
SA = 2(10)(10) + 2(10)(10) + 2(10)(10)
SA = 600cm
Answer:
No
Step-by-step explanation:
3 is above 2 (c<2). Where c is needed to be above -3 and less than 2.
That leaves -2,-1,0,1 as solutions.
