Juan analyzes the amount of radioactive material remaining in a medical waste container over time. He writes the function f(x) =

10(0.98)x to represent the amount of radioactive material that will remain after x hours in the container. Rounded to the nearest tenth, how much radioactive material will remain after 10 hours?

Answer:

8.2 units of radioactive material will remain after 10 hours

Step-by-step explanation:

Given : f(x)=10(0.98)^{x}

To Find : , how much radioactive material will remain after 10 hours?

Solution :

Since we are given a function that represents the amount of radioactive material remaining in a medical waste container over time.

f(x)=10(0.98)^{x}

Where x denoted hours

Since we are asked to find the amount of radioactive after 10 hours .

So, put x = 10 in the given function

f(10)=10(0.98)^{10}

f(10)=10*0.8170

f(10)=8.170

Thus f(10)=8.17 ≈ 8.2

Hence 8.2 units of radioactive material will remain after 10 hours

For radioactive decay, the amount should decrease over time. Given the function:
f(x)=10(0.98)^x
We substitute the time of x = 10 hours:
f(10)=10(0.98)^{10} \\ f(10) = 8.17
Therefore 8.2 units will remain after 10 hours.

Find the sum of the first 3 terms of a geometric sequence with a=96 and r=1/4 the sum is____.
viva [34]
For Geometric sequence, the next term is multiplied by the common ratio.

Common ratio, r = 1/4

1st term, a = 96

2nd term = ar = 96*1/4 = 24

3rd term = ar² = 96*(1/4)*(1/4) = 6

Sum of the first three terms =    96 + 24 + 6 = 126

F(a)=-2a +5<br> s(a)= a- 2 - 2a<br> Find f(a) +gla)
Aleks [24]

Answer:

-3a+8

Step-by-step explanation:

f(a)=-2a +5

s(a)= a-2-2a=-a+2

We are asked to determine

f(a) +g(a)

= (-2a +5)+ (-a+2)

=-2a+5-a+2

=-2a-a+5+2

=-3a+8

You have $1000 to invest in two different accounts. In order to save the money you need for college, you need to average 6.6 per
inysia [295]
Let x dollars be your investment at 7%;

then the investment at 3% is the rest (1000-x) dollars.


The total interest equation is

0.07x + 0.03*(1000-x) = 0.061*1000.


Express x and calculate

x = %280.061%2A1000-0.03%2A1000%29%2F%280.07-0.03%29 = 775.


ANSWER. $700 is the 7% investment; the rest, (1000-775) = 225 dollars is the 3% investment.
