its simple really the lobster will molt 4 times every year so take 12 times 4 to get 48. to get how many times a lobster molts in one year divide 20 by 5 to get 4

hope this helps :)

Identify the volume and surface area of the sphere in terms of π. HELP PLEASE!!

Helen [10]

Answer:

First choice V = 18,432π m^3; S = 2,304π m^2

Step-by-step explanation:

Start with the two formulas:

Volume of a circle:

$V = \dfrac{4}{3} \pi r^3$

Surface area of a circle:

$S = 4 \pi r^2$

Now use r = 24 m in each formula.

Volume:

$V = \dfrac{4}{3} \pi (24~m)^3$

$V = \dfrac{4}{3} \pi (13,824~m^3)$

$V = 18,432\pi~m^3$

Surface area:

$S = 4 \pi r^2$

$S = 4 \pi (24~m)^2$

$S = 4 \pi (576~m^2)$

$S = 2,304\pi ~m^2$

Answer: First choice V = 18,432π m^3; S = 2,304π m^2

A point located at (-5, -6) is reflected over the y-axis. What are the coordinates of the image? (-5, 6) (5, -6) (5, 6) (-6, -5)

BigorU [14]

<u>Answer:</u>

The correct answer option is (5, -6).

<u>Step-by-step explanation:</u>

We know that the following are the coordinates of a point:

$( - 5 , - 6 )$

If this point is reflected through y axis, we are to find the coordinates of its image?

If a point is reflected through y-axis, the sign of the x coordinate is changed so we get:

$( - 5 , -6 )$ $\implies$ (5, -6)

Gertrude started an experiment with 15 gummy bears. After 6 days, there were 1,523 gummy bears. Write an exponential function th

Lunna [17]

Answer:

y = 15·2.1599^x

Step-by-step explanation:

We know that the number changed by the ratio 1523/15 = 101.5333... in 6 days, so the daily multiplier is the 6th root of this:

b = 101.5333...^(1/6) = 2.1599 . . . rounded to 4 dp

Of course, the coefficient 'a' in the equation is the initial number, 15.

Your exponential equation is ...

y = 15·2.1599^x

a = 15

b = 2.1599
