The concentration of a drug in the bloodstream C(t) at any time t, in hours, is described by the equationC(t)=100t/t^2+25where t

alisha [4.7K]

Answer:

It will take 5 hours until it reaches its maximum concentration.

Step-by-step explanation:

The maximum concentration will happen in t hours. t is found when

$C'(t) = 0$

In this problem

$C(t) = \frac{100t}{t^{2} + 25}$

Applying the quotient derivative formula

$C'(t) = \frac{(100t)'(t^{2} + 25) - (t^{2} + 25)'(100t)}{(t^{2} + 25)^{2}}$

$C'(t) = \frac{100t^{2} + 2500 - 200t^{2}}{(t^{2} + 25)^{2}}$

$C'(t) = \frac{-100t^{2} + 2500}{(t^{2} + 25)^{2}}$

A fraction is equal to zero when the numerator is 0. So

$-100t^{2} + 2500 = 0$

$100t^{2} = 2500$

$t^{2} = 25$

$t = \pm \sqrt{25}$

$t = \pm 5$

We use only positive value.

It will take 5 hours until it reaches its maximum concentration.

4. The perimeter of a triangle is 105 inches. The longest side is 22 inches longer than the shortest side. The sum of the

Cloud [144]

Answer:

x = 45

y = 37

z = 23

Step-by-step explanation:

x + y + z = 105

x = z + 22

x + 15 = y + z

(z + 22) + 15 = y + z

37 = y

x + y + z = 105

(z + 22) + 37 + z = 105

2z = 46

z = 23

x + y + z = 105

x + 37 + 23 = 105

x = 45

What is the value of x in the equation 4x - 5 = -33

aniked [119]

Answer: $x=-7$

Step-by-step explanation:

$4x-5 =-33$

ad 5 to both sides

$4x=-28$

divide both sides by 4

$x=-7$

plug in x to double check

$4(-7)-5=-33\\-28-5=-33\\-33=-33$

hope this helps :3
