supose that the half-life of a cesium is 30 years. If there were initially 1000g of the substance,
a) give an exponential model for the situation
b) how much will remain after 200 years
Answers
After 200 years, 9.84 grams of Cesium would remain.
Let N represent the amount of substance after t years
The half-life of a cesium is 30 years., hence, this can be represented by exponential function:
[tex]N(t)=ab^t[/tex]
where a is the initial value and b is the multiplier.
There were initially 1000g of the substance
a) The exponential model for this situation is:
[tex]N(t) =1000(\frac{1}{2} )^{\frac{1}{30} t}\\\\N(t) =1000(\frac{1}{2} )^{\frac{t}{30}[/tex]
b) After 200 years (t = 200), the amount of Cesium remaining is:
[tex]N(200)=1000(\frac{1}{2} )^\frac{200}{30} \\\\N(200) = 9.84g[/tex]
Hence after 200 years, 9.84 grams of Cesium would remain

How many petals p would there be in a group of 11 flowers ? Write an equation to find the unknown. Then find the unknown.
Answers
Answer:
11
Step-by-step explanation:
The required expression that represents the total number of petals is P = n11, where n is the number of petals per flower.
Given that,
To determine how many petals p would there be in a group of 11 flowers.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Let the number of petals in the single flower is n,
The total number of petals among the 11 flowers is p,
p = n11
Thus, the required expression that represents the total number of petals is P = n11, where n is the number of petals per flower.

Answer:
9
Step-by-step explanation:
Simply plug -3 in for x.
-2(-3)^2-7(-3)+6
(-3)^2=9
9*-2= -18
-7*-3=21
-18+21=3
3+6=9
Answer:
f(-3) = 9
Step-by-step explanation:
Here we have a quadratic function in x: and we want to know the value of this function when x = -3.
Substituting -3 for x in f(x) = -2x^2 - 7x + 6, we get f(-3) = -2(-3)^2 - 7(-3) + 6, which works out to f(-3) = -2(9) + 21 + 6, or
f(-3) = -18 + 27 = 9
Thus, f(-3) = 9

452.16 rounded to the nearest tenth
Answers
Answer: 452.2
Step by Step Explanation: Find the number in the tenth place 1 and look one place to the right for the rounding digit 6 round up if this number is greater than or equal to 5 and round down if it is less than 5
.
Rounding 452.16 to the nearest tenth gives us: 452.1.
Given that we need to round 452.16 to the nearest tenth,
We look at the digit in the hundredth place, which is the second decimal place, and round 452.16 to the nearest tenth.
One is the digit at the hundredth position.
We round down because 1 is less than 5, therefore.
Simply drop all the digits following the tenths place and leave the tenths place digit alone if you want to round down.
Rounding 452.16 to the nearest tenth, we obtain: 452.1.
Hence rounding 452.16 to the nearest tenth gives us: 452.1.

50 = -1/3b + 20
what is b?
Answers
To find b, start by subtracting 20 from both sides:
50 = -1/3b + 20
-20 -20
30 = -1/3b
Now isolate b by dividing both sides by -1/3:
30/(-1/3) = (-1/3b)/(-1/3)
-90 = b
b is 90!
