E5 In (x + 1)<br> Simplify

pentagon [3]

Answer:

e^ (5 ln (x + 1)) = (x + 1)^5

Step-by-step explanation:

e5 In (x + 1) or did you mean e^ (5 ln (x + 1))

because then this would simplify a lot

e^ (5 ln (x + 1)) = e ^ (ln (x + 1)^5)

e^ (5 ln (x + 1)) = e ^ (ln (x + 1)^5) = (x + 1)^5

or did you mean (e^5) ( ln (x + 1)) = ln [(x+1)^(e^5)]

But I think you meant:

e^ (5 ln (x + 1)) = e ^ (ln (x + 1)^5) = (x + 1)^5

The number of bacteria in a refrigerated food product is given by N ( T ) = 22 T 2 − 123 T + 40 , 6 < T < 36 , where T is

antoniya [11.8K]

Answer:

$N(T(t)) = 1408t^2 - 385.6t - 105.52$

Time for bacteria count reaching 8019: t = 2.543 hours

Step-by-step explanation:

To find the composite function N(T(t)), we just need to use the value of T(t) for each T in the function N(T). So we have that:

$N(T(t)) = 22 * (8t + 1.7)^2 - 123 * (8t + 1.7) + 40$

$N(T(t)) = 22 * (64t^2 + 27.2t + 2.89) - 984t - 209.1 + 40$

$N(T(t)) = 1408t^2 + 598.4t + 63.58 - 984t - 169.1$

$N(T(t)) = 1408t^2 - 385.6t - 105.52$

Now, to find the time when the bacteria count reaches 8019, we just need to use N(T(t)) = 8019 and then find the value of t:

$8019 = 1408t^2 - 385.6t - 105.52$

$1408t^2 - 385.6t - 8124.52 = 0$

Solving this quadratic equation, we have that t = 2.543 hours, so that is the time needed to the bacteria count reaching 8019.

The ratio of minutes to gallons of water flowing through a garden hose is 2 to 12 carlota says that an equivalent ratio of minut

blagie [28]

Answer:

Carlota is not correct

Step-by-step explanation:

A ratio represents relationship between of two or more things.

Ratio of minutes to gallons of water flowing through a garden hose $=2:12$

Here,

$2:12=1:6$

Also,

It's given that an equivalent ratio of minutes to gallons is $6:1$

Now,

$1:6\neq 6:1$

Therefore,

Carlota is not correct
