Answer:

$r=\frac{9\cos \theta}{\sin^2 \theta}$

Step-by-step explanation:

The given equation in rectangular coordinates is;

$y^2=9x$

We use the relation;

$x=r\cos \theta$

and

$y=r \sin \theta$

This implies that;

$(r \sin \theta)^2=9(r \cos \theta)$

$r^2 \sin^2 \theta=9r \cos \theta$

Divide through by r to get;

$r \sin^2 \theta=9\cos \theta$

Divide both sides by $\sin^2 \theta$

$r=\frac{9\cos \theta}{\sin^2 \theta}$

The product of two numbers is 48. The first number is negative, and the second number is four more than twice the first number.

aksik [14]

First number is a and second one is 2a+4
a(2a+4)=48
a(a+2)=24
a^2+2a-24=0
(a+6)(a-4)=0
the question says a is negative so a=-6 b=-8

Are total emissions or per-capita emissions a better gauge when comparing the co2 emissions of various countries? why? emissions

algol13

The emissions per capita measurement is a better because it shows the number of people divided by the emissions.

<h3>What is the difference between total emissions and emissions per capita?</h3>

The emissions per capita show the emissions per each citizen or inhabitant, while the total emissions show only the emissions of the country.

<h3>Which one is better?</h3>

The per capita gauge is better because whether a country is polluting more or not depends on how much each citizen pollutes. This information is useful to create laws that reduce pollution.
