When the volume of a gas is

Mathematics
1 answer:
Fudgin [204]3 years ago
3 0

Answer: The initial volume is 593.76mL

Step-by-step explanation:

As you do not say anithing about the pressure, i guess that the pressure remains constant.

If the gas is an ideal gas, we have:

P*V = n*R*T

where P is pressure, n is number of moles and R is a constant.

Now, initially we have:

P*Vi = n*R*315°C

finally we have:

P*825mL = n*R*452°C

Now we can take the quiotient of those two equations and get:

(P*Vi)/(P*852mL) = (n*R*315°C)/( n*R*452°C)

Now we have:

Vi/852mL = 315/452

Vi =  (315/452)*852mL = 593.76mL

So when we expand the gas at constant pressure, we increase the temperature.

krek1111 [17]
The horizontal component of the velocity of the shot is 35 cos 40 ft/sec which is constant
Therefore:-
Velocity = distance / time
35 cos 40  = 40 / t

t = = 40 / 35cos40  =  1.49 seconds to nearest hundredth

The point P(5, −4) lies on the curve y = 4/(4 − x).
dalvyx [7]

Answer:

4

Step-by-step explanation:

Slope refers to the steepness of the line.

Slope is equal to change in value of y divided by change in value of x.

The slope of the secant line is given by \frac{f(x)-f(a)}{x-a}.

Given points are P\left ( 5,-4 \right )\,,\,Q\left ( x,\frac{4}{4-x} \right )

So, slope of the secant line is \frac{\frac{4}{4-x}+4}{x-5}=\frac{4+4(4-x)}{(x-5)(4-x)}=\frac{20-4x}{(x-5)(4-x)}=\frac{-4(x-5)}{(x-5)(4-x)}=\frac{-4}{4-x}=\frac{4}{x-4}

(i) At x = 4.9,

\frac{4}{4.9-4}=\frac{4}{0.9}=4.444444

(ii) At x = 4.99,

\frac{4}{4.99-4}=\frac{4}{0.99}=4.040404

(iii) At x = 4.999,

\frac{4}{4.999-4}=\frac{4}{0.999}=4.004004

(iv) At x = 4.9999,

\frac{4}{4.9999-4}=\frac{4}{0.9999}=4.0004

(v) At x =5.1,

\frac{4}{5.1-4}=\frac{4}{1.1}=3.636364

(vi)

At x = 5.01,

\frac{4}{5.01-4}=\frac{4}{1.01}=3.960396

(vii) At x = 5.001,

\frac{4}{5.001-4}=\frac{4}{1.001}=3.996004

(viii) At x = 5.0001,

\frac{4}{5.0001-4}=\frac{4}{1.0001}=3.9996

(b)

Really need helpppp?!
user100 [1]

Answer:

6.43

pls follow me and mark brainliest ...thank u

Step-by-step explanation:

length of side x will be

Tan tita = opp/adjacent

tan65 = x/3

tan 65 is 2.14

so...you are left with 2.14=x/3

by cross multiplying

x= 2.14 × 3

= 6.43
