The length (in centimeters) of a typical Pacific halibut t years old is approximately f(t) = 200(1 − 0.956e−0.18t). Suppose a Pa

horsena [70]

Answer:

7.2 years

Step-by-step explanation:

$f(t) =200(1 - 0.956e^{-0.18t})$

where f(t) is the length and t is the number of years old

given the Mike measures 148 cm, we need to find out the age

So we plug in 148 for f(t) and solve for t

$148 =200(1 - 0.956e^{-0.18t})$

divide both sides by 200

$\frac{148}{200} = 1 - 0.956e^{-0.18t}$

Now subtract 1 from both sides

$-0.26= - 0.956e^{-0.18t}$

Divide both sides by -0.956

$\frac{0.26}{0.956} =e^{-0.18t}$

Now take ln on both sides

$\frac{0.26}{0.956} =e^{-0.18t}$

$ln(\frac{0.26}{0.956} )=-0.18tln(e)$

$ln(\frac{0.26}{0.956} )=-0.18t$

divide both sides by -0.18

t=7.2

So 7.2 years

How to find what numbers a number is divisible by

nevsk [136]

If the number ends with an even number or a number that is always divisible by 2. Or every number that ends with 5 or zero is always divisible by 5 too. Bdause for example in a fraction we do 10/5 and it will be equal to 2/1 or 2. Hope it helped you!

{4x-2y<0}<br> {5x+3y<-11}

kkurt [141]

Finding the sum for y in the equation 4x-2y< 0
so 4x - 2y = 0
4x - 2y - 4x would equal 0 - 4x
-2y = -4x
-2y divided by -2 equals -4x / -2
That means y=2x

There are 3 consecutive integers. If the smallest one is n, find the sum of 3 integers.

Dvinal [7]

Answer:

<h3> 3n + 3</h3>

Step-by-step explanation:

The consecutive integers are increasing by 1

n ← the smallest integer

n+1 ← the middle integer

n+1+1 = n+2 ← the largest integer

The sum:

S = n + n+1 + n+2

S = 3n + 3
