Answer:

- the pressure will decrease

(volume is doubled ,the pressure reduced by half).

Step-by-step explanation:

P_1 V_1=P_2 V_2

This equation shows that, as volume increases, the pressure of the gas decreases in proportion.

Similarly, as volume decreases, the pressure of the gas increases.

The equation for the cross section of a parabolic satellite television dish is y = 1/45 x2, measured in inches. How far is the f

patriot [66]

Answer:

11.25

Step-by-step explanation:

The equation for a parabola is:

y − k = 1/(4p) (x − h)²

where (h, k) is the vertex and p is the distance from the focus to the vertex.

1/(4p) = 1/45

4p = 45

p = 11.25

The distance from the vertex to the focus is 11.25 inches.

A number picked at random from the numbers 1 through 15 is prime. This "question" is on my study guide for Unit 6 Probability an

Sphinxa [80]

Solution:

we are given that

A number picked at random from the numbers 1 through 15 is prime.

As we know the number between 1 and 15 which are primes are listed below

2,3,5,7,11,13.

Here total number of favourable outcomes are 6.

The numbers 1 through 15 are as below:

1,2,3,4,5,6,7,8,9,10,11,12,13,14,15.

Here total number of possible outcoes are 15.

Hence the probability that if a number picked at random from the numbers 1 through 15 is prime $=\frac{6}{15}=\frac{2}{5}=0.40$

Hence the probability that if a number picked at random from the numbers 1 through 15 is prime is 0.4

Resultado:

${ \: \: \: \: \: \: \: \: \: \Rightarrow 20 + 60 + 80 = 160}$

$\: \: \: \: \: \: \: \: \: \sf \Rightarrow20+60+80=160$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: { \sf \Rightarrow160 - 100 = 60}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \sf \Rightarrow160−100=60$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: { \sf \Rightarrow100 - 60 = 40}$
