If a and b are in parenthesis, the answer is: c = d*e^(n/(a+b)) If not, the answer is: c = d*e^((n/b)-(a/b))

I believe you get .0030864. solve what's in the parenthesis first then ^2. turn fractions into decimal format then add them and ^2.

A unit of measurement equal to 149.6 million kilometers, the mean distance from the center of the earth to the center of the sun.

Spec heat of ice: 2.09 j/(g*deg C) Spec heat of liq water: 4.18J/(g*deg C) Enthalpy of fusion: 334 J/g Enthalpy of vaporization: 2250 J/g

Answer in Minutes = 63 minutes. Thanks

addition&subtraction= round to least number of decimal places multiplication&division=round to least number of significant figures present.

use conversion factor. 3.5in X 1cm _____ = 1.4 cm 2.54 in. round to two significant figures. answer is= 1.4cm

That's not possible. But 10^-1 is. You move your decimal to the left for negative exponents and you move your decimal to the right for positive exponents. If you had a value of 1 X 10^-2 for example you would move your decimal two places to the left which...

How do you know by looking at them?

You would use gay-lussac's law. P1/P1 = P2/P2 SO you plug your values in and get... (660 torr)/(20celsius) = (? torr)/(40celsius) .... (26400 torr/celsius) = (20celsius)(? torr) then divide by 20 degrees celsius and then you get 1320 torr as your answer.

THE VOLUME WOULDN'T HAVE ANY EFFECT ON THE TEMPERATURE. FOR A GAS IN A CLOSED CONTAINER, WITH THE PRESSURE CONSTANT THE TEMPERATURE DOESN'T CHANGE THE VOLUME. WHEN TEMPERATURE INCREASES, PRESSURE INCREASES. THEY ARE DIRECTLY PROPORTIONAL.

oh okay! I get it now, thanks!:)

you plug in zero for x and get 6(0)-7y=-42 and then you get-7y=-42 which is y=6. and then you plug in zero for y and get 6x-7(0)=-42 and then you get 6x=-42 which is x=-7. so your points are (-7,6) and then graph them.

Oh and then you put your equation in slope intercept form y=mx+b. and get -7y=-6x-42 and divide by 7. so your line will be y=6/7x +6.

My teacher said the answer is 78.92 amu and 50.69%. But i keep getting 81.13amu and i don't know how to get the percentage.

(79.904)=(80.9163)(0.4931) + x(0.4931) 79.904=39.90 + 0.4931x 40.004=0.4931x x=81.13amu

oh okay i get it now, thank you! Why did you subtract 1.00 from the abundance though? how do you know?

Use the Molarity Formula Molarity= moles/liters of solution Molarity= moles/0.050 Liters To find moles you have to find the moles of each sample of KBr. SO 1.00M KBR times .025liters =.025moles And then 0.800M KBR times .075liters=.060moles. Then you add...

third one is true

For D)..... Your parabola should be negative because of the -2X^2. SO the parabola when you graph it is a backwards U. The middle of the backwards "U" has a high maximum so your tickets should be at a peak during the middle of the sale.

As time passes, the ticket sales get higher. Each time you plug in different values of X, the day tickets go on sale, your Y value increases.

Your answer is correct.

people need to reread the question on the test they have because the answers may not be in the same order

so is the correct answer ( D )

so correct answer is house

What is the equation for this problem

Corrected the question from earlier If you have a line intersecting at (3,6). what equation would represent both lines?

x<-8 ,trust me,

One is incorrect, that being the 4th. correct answer is utilitarian products.
