How coral polyps form a reef

Fofino [41]

Coral reefs begin to form when free-swimming coral larvae attach to submerged rocks or other hard surfaces along the edges of islands or continents. As the corals grow and expand, reefs take on one of three major characteristic structures —fringing, barrier or atoll.

A 3.00-g copper penny at 25.0°C drops from a height of50.0 m to the ground. (

Gnoma [55]

The potential energy, E, of the penny is given by E=mgh. The energy, Q, required to raise the temperature of an object by an amount ΔT is given by Q=mcΔT. We can equate these two to get the result but we must use proper units and include the 60%:
(0.6)mgh=mcΔT
We see we can divide out the mass from each side
0.6gh=cΔT, then 0.6gh/c=ΔT
(0.6)9.81(m/s²)50m/385(J/kg°C) = 0.7644°C
since this is the change in temperature and it started at 25°C we get
T=25.7644°C
As you can see the result does not depend on mass. The more massive the copper object the more potential energy it will have to contribute to the heat energy, but the more stuff there will be to heat up, and the effect is that the mass cancels.

A small business makes cookies and sells them at the farmer's market. The fixed monthly cost for use of a Health Department–appr

DENIUS [597]

Answer:

Cost function:

$C(x)=790+2.88x$

Revenue function

$R(x)=6x$

Profit function

$P(x)=3.12x-790$

Dozens needed for a specific profit P

$x=\dfrac{P-790}{3.12}$

If 150 dozen cookies are sold the profit is negative, so the business is loosing $322.

Step-by-step explanation:

We can list the costs as:

- Fixed monthly cost, $790/month.

- Variable costs, $0.24/cookie, which are (12*0.24) = $2.88 a dozen.

Then, we can write the cost function C(x) as:

$C(x)=790+2.88x$

being C(x): the monthly cost and x: the number of dozens produced per month.

The revenue can be calculated as the price ($6 a dozen) multiplied by the number of dozens x:

$R(x)=6x$

The profit can be calculated substracting the total cost C(x) from the revenue R(x).

$P(x)=R(x)-C(x)\\\\P(x)=(6x)-(790+2.88x)=(6-2.88)x-790\\\\P(x)=3.12x-790$

The number of cookies (in dozens) that must be produced and sold for a monthly profit can be calculated from the previous equation for P(x).

For a monthly profit P, the number of dozens that need to be sold are:

$P=3.12x-790\\\\P+790=3.12x\\\\\\x=\dfrac{P-790}{3.12}$

If 150 dozen cookies are sold, the profit made is:

$P(150)=3.12(150)-790=468-790=-322$

The profit is negative, so the business is loosing $322.

Describe how to write 2,915,000,000 in scientific notation

Goshia [24]

Answer:

2.915 × 10^9

Step-by-step explanation:

you count the from right to left since its a positive number until you get one number in front. That's where you place your decimal. Since there's 9 numbers behind the 2 it will be 10 to the power of 9.
