If the question is

$log_2(x)+log_2(x-6)=4$

which can be simplified to

$log_2(x(x-6))=4$

By the definition of log, $log_a(x)=y$ means $a^y=x$

2^4=x(x-6)=x^2-6x

Simplify and solve for x

x^2-6x-16=0

(x+2)(x-8)=0

x=-2 or x=8

Since no answer choices are given, one of the equations in the above solution should appear in the answer choices.

A 0.30 kg bird flies in a horizontal curve of radius 20 m at 15 m/s. The force exerted by the air on the bird is about

monitta

Answer:

<h2>b) 3.48 N approx.</h2>

Step-by-step explanation:

<em>The bird will experience a centripetal force, this is the force exerted on a body that moves through a curve path.</em>

$F_c = \frac{mv^2}{r}$

Fc=centripetal force

m=mass

v=velocity

r=radius

Step one:

given data

mass of bird m=0.3kg

the radius of curve r= 20m

velocity v= 15 m/s

Substituting we have

$F_c = \frac{0.3*15^2}{20}\\\\F_c= \frac{0.3*225}{20}\\\\ F_c=\frac{67.5}{20}\\\\F_c=3.37N$

<u>The force is 3.37N</u>

The percent yield is calculated by dividing the actual yield by the theoretical yield times 100. True False

erastovalidia [21]

Answer:

True

Step-by-step explanation:

Correct.

For example.

Suppose the actual yield is of 80 and the theoretical yield is of 100. We want to, for example, know the percentage of the yield. First we divide 80 by 100, which is 0.8, a decimal value. To write as a percentage, we multiply it by 100.

So the correct answer is:

True
