Answer:
The correct option is (B)
.
Step-by-step explanation:
The exponential decay function is as follows:
Here,
<em>y = </em>final value
<em>a</em> = initial value
<em>r</em> = decay rate
<em>t</em> = time taken
It is provided that:
<em>a = </em>150 mg
<em>r</em> = 9% = 0.09
Then the next hour the amount of caffeine in the body will be:
Then after two hours the amount of caffeine in the body will be:
Similarly after 10 hours the amount of caffeine in the body will be:
Then the inequality representing the range of the exponential function that models this situation is:
Thus, the correct option is (B).
I think the answer is Pondicherry
Step-by-step explanation:
Simple
The percent of bus and car is 35
So 35% x 1500 = 525
Total bus and car students are 525
Since we don't have the measurements for the trapezoid, we can't find the exact cost. However, I can explain how to solve the problem.
First, you need to find the the total area of the pool cover. Since it is in the shape of a trapezoid, use the formula below.
A = 0.5(h)(the sum of the bases)
Once you have the area, multiply by 0.79 and you will have the cost.
There are many pairs you could do, but I'm going to choose this one:
You can multiply them together, and get (that's how you know if they are factors):
Hope this helped!
