Answer:

C. 22L

Step-by-step explanation:

STP is 273 K and 1 atm

Remember that R=0.0821 atm*L/mol*K

Put this into ideal gas law and solve for volume

PV=nRT → V=nRT/P

V=[(1mol)*(0.0821 atm*L/mol*K)*(273 K)]/(1 atm)

V=[22.4133 atm*L]/(1 atm)=22.4133 L

So the answer is 22 L

Is one flag a translation image of the other, or a rotation image? Explain.
Afina-wow [57]
Answer: The flag that is below the horizontal axis, is the sownward translation of the flag that is over the same axis.

Explanation:

Note that a translation transformation only moves the flag some units but does not change the direction. A rotation would have changed where the flag points (for example to the left instead of to the right).

If y=x^2 and x=(-8) then y =...
lutik1710 [3]

Answer:

-64

Step-by-step explanation:

If

y=x^2

and the x represents -8

Your answer will be -64

By saying that x=(-8)   all you have to do is plug in the negative 8 to the original equation of y=x^2. This would make it   y=(-8)^2

When you plug in negative 8 to the second power into the calculator your answer will be -64

I hope this helps king!

Use synthetic division to find P (-10) for P(x)=2x^3+14x^2-58x
Savatey [412]
The polynomial remainder theorem states that the remainder upon dividing a polynomial p(x) by x-c is the same as the value of p(c), so to find p(-10) you need to find the remainder upon dividing

\dfrac{2x^3+14x^2-58x}{x+10}

You have

..... | 2 ...  14  ... -58
-10 |    ... -20  ... 60
--------------------------
..... | 2 ...  -6  ....  2

So the quotient and remainder upon dividing is

\dfrac{2x^3+14x^2-58x}{x+10}=2x-6+\dfrac2{x+10}

with a remainder of 2, which means p(-10)=2.
