Aneli [31]3 years ago

Answer:

  \log_{19}{361}=2

Step-by-step explanation:

We know that taking logarithms performs the transformation ...

  b^e=x\\\\e\cdot\log{b}=\log{x}\quad\text{take logs}\\\\e=\dfrac{\log{x}}{\log{b}}\quad\text{divide by $\log{b}$}\\\\\log_b{x}=e\quad\text{use the change of base formula}

Then for b=19, e=2, x=361, we have

  \boxed{\log_{19}{361}=2}

a culture started with 4,000 bacteria. after 7 hours,it grew to 5,200 bacteria. Predict how many bacteria will be present after
serious [3.7K]
Start with trying to figure out rate (r):
P = i•e^rt
5200 = 4000•e^(r•7)
5200/4000 = 1.3 = e^7r
ln 1.3 = ln (e^7r)
.262 = 7r•1, because the ln (e) = 1
r = .262/7 = .0375
Now that you have the rate, plug in that for r and 9 hours as the new t, with again our 4200 as the i
P = i•e^rt = 4200•e^(.0375•9)
P = 4200•1.401 = 5,886 bacteria

Can someone help me with 5 and 6?
Lemur [1.5K]
Sine = (opposite)/(hypotenuse). Cosine = (adjacent)/(hypotenuse). Tangent = (opposite)/(adjacent). Fill in the numbers. They're all on the drawing . Then memorize these definitions. You'll need them as long as you're in school, and possibly after.
