Answer:

$135.63

Step-by-step explanation:

first and foremost, the formula for interest is I = Prt. P is the principal, r is the rate, and t is the time.

so plug in the numbers you have. Always convert the rate to a decimal. The rate would be 0.0.45. Plug in 54.93 for the I and plug in 9 for the time. It would look like this:

54.93 = P(0.045)(9) --> 54.93 = 0.405P --> P = 135.63

A bacteria population is 2000 at time t = 0 and its rate of growth is 1000 · 5t bacteria per hour after t hours. what is the pop
natima [27]

Since you are given the rate of growth, the population must be computed from the integral ...

\displaystyle p(t)=2000+\int_{0}^{t}{\left(1000\cdot 5^{t}\right)}\,dt=2000+\frac{1000}{\ln{(5)}}\cdot \left(5^{t}-1\right)\\\\=2000+\frac{1000}{\ln{(5)}}\cdot 4\approx 4485\qquad\mbox{after 1 hour}

Use this figure to find value of FOD
stepladder [879]
Hey there!

BOD is a 90 degrees angle. Make an equation for that angle. 15+12+x=90. Simplify this to 27+x=90. You need to isolate x, so subtract 27 on each side to get x=63. C is the answer.

I hope this helps!
