Answer: |55.75 – (-15.8)| = |55.75 + 15.8| = |71.55| = 71.55

Step-by-step explanation: The distance between two positions with longitudes A and B is given by ||A| - |B|| if the two positions are at the same side of the meridian (0 degrees longitude) and |A| + |B| if both positions are at different sides of the meridian.

Ocean sunfish are well known for rapidly gaining a lot of weight on a diet based on jellyfish. The relationship between the elap

Answer:

Every day, the mass of the sunfish is multiplied by a factor of <u>[ln(1.34)/6]. </u>

<u></u>

Step-by-step explanation:

You have the following function:

$M(t)=(1.34)^{\frac{t}{6}+4}$

To know what is the factor that multiplies the mass of the sunfish each day, you derivative the function M(t):

$\frac{dM(t)}{dt}=(1.34)^{\frac{t}{6}+4}(\frac{1}{6})ln(1.34)\\\\\frac{dM(t)}{dt}=\frac{ln(1.34)}{6}[(1.43)^{\frac{t}{6}+4}]\\\\\frac{dM(t)}{dt}=\frac{ln(1.34)}{6}M(t)$ (1)

where you have used the following general derivative:

$g(t)=a^{f(t)}\\g'(t)=a^{f(t)}f'(t)ln(a)$

The derivative give you the increase in the mass per day (because t is days). By the expression (1) you can conclude that each day the mass increase a factor of [ln(1.34)/6].

Every day, the mass of the sunfish is multiplied by a factor of <u>[ln(1.34)/6]. </u>

Solving the expression: $(\frac{2}{3}a^2b^2)^2(-3ab)^4$ we get $36a^8b^8$

Step-by-step explanation:

We need to solve the expression: $(\frac{2}{3}a^2b^2)^2(-3ab)^4$

Solving:

Using exponent rule: $(a^b)^c=a^{bc}$ and another rule: $x^a.x^b=x^{a+b}$

$(\frac{2}{3}a^2b^2)^2(-3ab)^4\\=\frac{4}{9}a^4b^4(81a^4b^4)\\=\frac{4}{9}*81a^{4+4}b^{4+4}\\=4*9a^8b^8\\=36a^8b^8$

So, solving the expression: $(\frac{2}{3}a^2b^2)^2(-3ab)^4$ we get $36a^8b^8$
