The amount of Plutonium that remains after 36 months is 0.05
The equation for the amount of Plutonium after t months is
[tex]\mathbf{P(t) = 12e^{-0.1507t}}[/tex]
After 36 months; we have: t = 36.
Substitute 36 for t in P(t).
So, we have:
[tex]\mathbf{P(36) = 12e^{-0.1507 \times 36}}[/tex]
Simplify the exponent
[tex]\mathbf{P(36) = 12e^{-5.4252}}[/tex]
Evaluate the exponent
[tex]\mathbf{P(36) = 12 \times 0.004404}[/tex]
Multiply
[tex]\mathbf{P(36) = 0.052848}[/tex]
Approximate to 2 decimal places
[tex]\mathbf{P(36) = 0.05}[/tex]
Hence, the amount that remains is 0.05

The circumference of a circle equals 2 r, where r is the radius. Find
the circumference of a compact disc that has a radius of 6.0 cm
Answer:
The answer is 37.68 or 37.7
Step-by-step explanation:
What you have to do first is find the diameter. So you have to multiply the radius (r) by 2 to get the diameter. 6 times 2 is 12. After that you, will multiply 12 by pi, or 3.14 to get 37.68
find the lengths of lien segments AC & CB
Answer:
AB = 28cm
point C partitions AB into a ratio 1:3
they say to find the lengths of AC and CB
Usually in maths questions like this look at the order of things placed. Meaning…
ratio — 1:3
find — AC and CB
1 — AC
3 — CB
so now we know
1:3
AC:CB
1+3 = 4
28/4 = 7
7*1 = 7 = AC
7*3 = 21 = CB

it is predicted that by 2050 there will be 10^10 people living on earth. approximatrly will be 10^12 trees. how many trees for each person?
Interesting question. Does that mean near the end of humanity?
Solution 1:
10^10 = 1,000,000,000
10^12 = 100,000,000,000
100,000,000,000/1,000,000,000 = 100 trees per person
Solution 2:
10^12 / 10^10 --- 10^10 / 10^10
10^2/1 = 10^2 = 100 trees per person

ANSWER USING STEPS: find the inverse function of y=-5x-7
the inverse of y is =x+7
Step-by-step explanation:
y=5x-7
then solve for x
5x=y+7
x=(y+7)/5
then exchange x with y
y=(x+7)/5
The inverse of the given function is expressed as:
-(x + 7)/5
How to find the inverse of the function?The given function is expressed as:
y = -5x - 7
Replacing y with x and vice versa gives us:
x = -5y - 7
Add 7 to both sides gives:
x + 7 = -5y
divide both sides by -5 gives us:
-(x + 7)/5 = y
Thus, we conclude that the inverse of the given function is expressed as:
-(x + 7)/5

Step-by-step explanation:
Let's solve for C.
[tex]F=\frac{9C}{5}[/tex]
Step 1: Flip the equation.
[tex]\frac{9}{5} C+32=F[/tex]
Step 2: Add [tex]-32[/tex] to both sides.
[tex]\frac{9}{5} C+32+-32=F+-32[/tex]
[tex]\frac{9}{5}C=F-32[/tex]

Set A contains all prime numbers squared. Set B contains all multiples of 4. How many numbers are in the intersection of Set A and Set B
Answer:
The intersection operation is denoted by the symbol ∩. The set A ∩ B—read “A intersection B” or “the intersection of A and B”—is defined as the set composed of all elements that belong to both A and B. Thus, the intersection of the two committees in the foregoing example is the set consisting of Blanshard and Hixon.
