nordsb [41]

Answer:

Time,t that it will elapse before the concerntration of the dye in the tank reaches1% of its original value is 460.52 seconds

Step-by-step explanation:

Let Q(t) = amount of dye for all time,t.

Let Q'= rate in - rate out.

But Q/200 = concerntration of dye

Therefore rate out= Q/200 ×2.

Q'/Q = - 1/100

Dividing by Q gives

Ln/Q/ + c = -1/100t + c1

Integrating both sides with respect to t

Ln/Q/ = -1/100t + c2.

c1 and c1 are just another constants

Q= c3e^-t/100

Exponentiating both sides will cause the absolute values to get absorbed into the constants giving rise to a new constant c3

200= c3-0/100

c3= 200

2= 200e^-t/100

Ln1/100= - t/100

Ln0.01 = - t/ 100

Cross multiply

t= Ln0.01 × 100

t = 4.6052 ×100

t = 460.52seconds

What is the solution to the equation?<br> a+5 2/3=9<br><br> PLEASE HELP!!!!
Leona [35]

Answer:

a = -25

Step-by-step explanation: a+ 52/3 =9

multiply both sides by 3

3(a+52)/3 = 9.3

Simplify

a+52=27

Subtract 52 from both sides

a+52-52=27-52

Simplify

a= -25

A catapult is malfunctioning and not throwing objects in the intended manner. The builders have modeled the path of the objects
Elenna [48]

Answer:

The equation is y ^ 2 = \frac{x + 1}{2}

Step-by-step explanation:

The parameter that we have is t. We want to eliminate this parameter in both equations, therefore in the first equation we solve for t and in the second equation we solve for the variable t.

We have:

x = 2t-1\\\\x + 1 = 2t\\\\t = \frac{x + 1}{2}

Now we solve the other equation for t.

y= \sqrt{t}

y ^ 2 = t    <em> because</em>   t> 0

As t = y ^ 2 and also t = \frac{x + 1}{2}

Then:

y ^ 2 = \frac{x + 1}{2}
