The right answer for the question that is being asked and shown above is that:

This can be answered using the Pythagorean Theorem.
h2 = a2 + b2
h = square root (10^2 + 7^2)
h = square root (100 + 49)
h = square root (149) cm

So the correct answer is h = square root (149) cm

Answer:

$P=40(1.03526)^{t}$

Step-by-step explanation:

Exponential Growth

The natural growth of some magnitudes can be modeled by the equation:

$P=P_o(1+r)^{t}$

Where P is the actual amount of the magnitude, Po is its initial amount, r is the growth rate and t is the time.

The initial number of bacteria is Po=40 and it doubles (P=2Po) at t=20 min. With that point we can find the value of r:

$2P_o=P_o(1+r)^{20}$

Simplifying:

$(1+r)^{20}=2$

Solving for 1+r:

$1+r=\sqrt[20]{2}$

$1+r=1.03526$

The exponential function that models the situation is:

$\mathbf{P=40(1.03526)^{t}}$
