When 8 is added to the number that is produced by doubling the number x, the result is equal to 8 times the number that is 5 les

Natasha_Volkova [10]

Hello. In order to solve this problem, you need to write an equation. Hence, you determine this equation:

8 + 2x = 8(x-5)
8 + 2x = 8x - 40
8 + 40 = 8x - 2x
48 = 6x
x = 8.

A bacterial culture grows exponentially according to the function n(t)=n(e^n), where n(t) is the quantity after t hours and n is

mart [117]

Answer:

$n(t=2) = 2 e^{1.386294361(2)}=32 grams$

So then after 2 hours we will have 32 grams.

Step-by-step explanation:

For this case we have the followin exponential model:

$n(t) = n e^{rt}$

n(t) is the quantity after t hours, n is the original quantityand t represent the hours and r the rate constant.

For this case we know that n(0) = 2 grams and n(3) = 128 grams and we want to find n(2)=?

From the initial condition we know that n = 2, and we have the model like this:

$n(t) = 2 e^{rt}$

Now if we apply the other conditionn(3) = 128 we got:

$128 = 2 e^{3r}$

If we divide both sides by 2 we got:

$64= e^{3r}$

If we apply natural log for both sides we got:

$ln(64) = 3r$

$r = \frac{ln(64)}{3}=1.386294361$

And our model is this one:

$n(t) = 2 e^{1.386294361t}$

And if we replace t = 2 hours we got:

$n(t=2) = 2 e^{1.386294361(2)}=32 grams$

So then after 2 hours we will have 32 grams.

If a vertical pole 30 ft tall casts a shadow 8ft long, how long would the shadow of 40-ft pole be at the same time and place

TEA [102]

Since it as at the same time and place.

Let x be the length of the shadow of the 40-ft pole.

The ratio from 30 and 8 would have to be the same as 40 and x.

30:8 = 40:x

30/8 = 40/x Cross multiply

30x = 40*8

x = 40*8 / 30 = 32/3 = 10.67

Length of shadow for 40ft is 10.67 ft.
