Answer:
Area= 1371.72m^2
Perimeter: 251.84m
Step-by-step explanation:
A1=L*W
A1=38*28
A1=1064
A2=3.14*r^2
A2=3.14*196
A2=615.44/2
A2=307.72
A1+A2=1371.72
Answer:
To solve this problem, we need to transform the adjectives below to verbs.
- Yummy : Savor
- Clean : To clean
- Shiny : To shine
We can form the following sentences:
- My siste savors the meal, and she thinks is yummy.
- I clean my apartment every single day, it's so clean.
- The sun shines all day, it's a shiny object.
Answer:
The initial mass of the sample was 16 mg.
The mass after 5 weeks will be about 0.0372 mg.
Step-by-step explanation:
We can write an exponential function to model the situation.
Let the initial amount be A. The standard exponential function is given by:
Where r is the rate of growth/decay.
Since the half-life of Palladium-100 is four days, r = 1/2. We will also substitute t/4 for t to to represent one cycle every four days. Therefore:
After 12 days, a sample of Palladium-100 has been reduced to a mass of two milligrams.
Therefore, when x = 12, P(x) = 2. By substitution:
Solve for A. Simplify:
Simplify:
Thus, the initial mass of the sample was:
5 weeks is equivalent to 35 days. Therefore, we can find P(35):
About 0.0372 mg will be left of the original 16 mg sample after 5 weeks.
