WILL GIVE BRAINLIEST
Evgesh-ka [11]
All you have to do is plug in the given values into the given equation and evaluate.

The expression is,

A(t) =  l{e}^{rt}
But we have to analyze the problem carefully. This is a natural phenomenon that can be modelled by a decay function. The reason is that, after every hour we expect the medicine in the blood to keep reducing.

Therefore we use the decay function rather. This is given by,


A(t) =  l{e}^{-rt}

where,

l = 100 \: milligrams

r =  \frac{14}{100}  = 0.14

and

t = 10 \: hours

On substitution, we obtain;

A(10) =  100 \times {e}^{ - 0.14 \times 10}


A(10) =  100 \times {e}^{ - 1.4}



Now, we take our calculators and look for the constant
e

,then type e raised to exponent of -1.4. If you are using a scientific or programmable calculator you will find this constant as a secondary function. Remember it is the base of the Natural logarithm.



If everything goes well, you should obtain;

A(10) =  100 \times 0.24659639


This implies that,


A(10) =  24.66

Therefore after 10 hours 24.66 mg of the medicine will still remain in the system.

The volume of a cone with a height of 10 meters is 20 pi cubic meters. what is the diameter of the cone?
lesya [120]

Answer:

2√6 m

Step-by-step explanation:

The formula for the vol. of a cone is V = (1/3)(area of base)(height).

Here, V = 20π m³ = (1/3)(area of the base)(10 m)

We need to solve for (area of the base).

Multiplying both sides of this equation by (3/10) results in:

(3/10)(20 π m³) = (area of the base)

This simplifies to 6π m² = (area of the base)

We still must find the diameter of the base.  Let's find the radius of the base first:      The formula for the area of a circle is A = πr².  Here we have 6π m² = πr², which tells us that r² = 6 m².  Since d = 2r, and r = d/2, r² = d²/4.     Then the equation 6 m² = r²  becomes:

6 m² = d²/4.

Solve this for d.   Multiplying both sides by 4, we get:

24 m² = d²2, and d = √(24 m²) = 2√6 m  

The cone diameter is 2√6 m.
