1) (2i-4)-(6i+9) = 2i-4-6i-9 = -4i-13

2) (-3+8i)+(3-8i) = -3+8i+3-8i = 0+0i = 0

A right rectangular prism has a base with sides 6 cm and 8 cm. If the volume of the prism is 624 cm^3, find the height of the pr

nika2105 [10]

Answer:

H=13cm

Step-by-step explanation:

Volume= Length x Width x Height

v=624cm^3

L=8cm

W=6cm

8cm x 6cm=48cm^2

Divide 624cm^3 by 48cm^2= 13cm

H=13cm

Hope this helps!

What equation best models this data?(use y to represent the population of rabbits and t to represent the year, assuming that 201

liraira [26]

If we see the data closely, a pattern emerges. The pattern is that the ratio of the population of every consecutive year to the present year is 1.6

Let us check it using a couple of examples.

The rabbit population in the year 2010 is 50. The population increases to 80 the next year (2011). Now, $\frac{80}{50}=1.6$

Likewise, the rabbit population in the year 2011 is 80. The population increases to 128 the next year (2012). Again, $\frac{128}{80}$ $=1.6$

We can verify the same ratio with all the data provided.

Thus, we know that the population in any given year is 1.6 times the population of the previous year. This is a classic case of a compounding problem. We know that the formula for compounding is as:

$F=P\times r^n$

Where $F$ is the future value of the rabbit population in any given year

$P$ is the rabbit population in the year "0" (that is the starting year 2010) and that is 50 in this question. (please note that there is just one starting year).
