PLEASE GOD HELP ME!!!!

Another expression for the given rational function is $x =r^\frac{1}{2}s^\frac{1}{2}$

<h3>Indices expression</h3>

Given the rational function expressed as:

x = √rs

We can reconstruct the expression by writing it using exponents as shown;

$x =\sqrt{rs}=(rs)^{\frac{1}{2} }$

Separate to have:

$x =r^\frac{1}{2}s^\frac{1}{2}$

Hence another expression for the given rational function is $x =r^\frac{1}{2}s^\frac{1}{2}$

Please Solve this, it would be extremely helpful for me.

Sidana [21]

Answer:

Step-by-step explanation:

1) ΔCPD & ΔEPF

∠CPD = ∠EPF { Vertically opposite angles}

∠CDP = ∠PFE {CD║EF, FD is transversal, Alternate interior angles are equal}

ΔCPD ≈ΔEPF {AA criteria for similarity }

$\frac{DC}{EF} =\frac{PC}{EP}\\\\\\\frac{27}{EF}=\frac{15}{7.5}\\\\$

Cross multiply

EF * 15 = 27 * 7.5

$EF =\frac{27*7.5}{15}\\\\$

EF = 27 * 0.5

EF = 13.5 cm

ii) EF // AB, so Triangles ACB & ECF are similar triangles

$\frac{AB}{EF}=\frac{AC}{EC}\\\\\frac{22.5}{13.5}=\frac{AC}{22.5}$

$AC= \frac{22.5*22.5}{13.5}\\\\AC=37.5 cm$

AC = 37.5 cm

Determine what type of study is described. Explain. Researchers wanted to determine whether there was an association between hig

victus00 [196]

Answer:

Experimental Study

Step-by-step explanation:

In an experimental study, the researchers involve always produce and intervention (in this case they were asked whether their tendency was to express or to hold in anger and other emotions. The degree of suppression of emotions was rated on a scale of 1 to 10) and study the effects taking measurements.

These studies are usually randomized ie subjects are group by chance.

As opposed to observation studies, where the researchers only measures what was observed, seen or hear without any intervention on their parts.
