Answer:

The senior class will have 100 members in the 13th year.

Step-by-step explanation:

Use the compound interest equation with a negative interest rate:

A = P(1 + r/n)^(n)(t)

Let n be 1 since we're looking for a specific year.

100 = 250(1 - 0.07)^t

100/250 = (0.93)^t

0.4 = (0.93)^t

t = 13 years

Please assist me with this problem

Nimfa-mama [501]

Answer:

d. about 50 times larger

Step-by-step explanation:

The given expressions for magnitude (M) can be solved for the intensity (I). Then the ratio of intensities is ...

$\dfrac{I_2}{I_1}=\dfrac{I_0\cdot 10^{M_2}}{I_0\cdot 10^{M_1}}=10^{M_2-M_1}=10^{4.2-2.5}\\\\=10^{1.7}\approx 50$

The larger earthquake had about 50 times the intensity of the smaller one.
