(w^5 z^2 )(−9w^2 z^5)
Lady_Fox [76]
We have that
(w^5*z^2)*(-9*w^2*z^<span><span>5)</span> 

</span><span>Multiplying exponential expressions
we know that
</span>w^5<span> multiplied by </span>w^<span>2 = w</span>^<span>(5 + 2) = w</span>^7
and
z^2<span> multiplied by </span>z^<span>5 = z</span>^<span>(2 + 5) = z</span>^7

therefore
(w^5*z^2)*(-9*w^2*z^5) =-9*( w^7)*( z^7)
-9*( w^7)*( z^7)=-(3^2)*( w^7)*( z^7)

the answer is
-(3^2)*( w^7)*( z^7

Which variable is most important to the following problem? At 9:00 a.m., a wind speed of 20 miles per hour was recorded. After t
slavikrds [6]

Answer:

option-C

Step-by-step explanation:

We are given

At 9:00 a.m., a wind speed of 20 miles per hour was recorded

So, initial wind speed =20 miles per hour

Each measurement showed an increase in wind speed of 3 miles per hour

The strongest wind was recorded at 4:00 p.m

so,

top wind speed = initial wind speed + ( total number of hours between 9:00 am and  4:00 pm)*(change in wind speed)

top wind speed = 20 mph+(16-9)*3

=20+7\times 3

=41 miles per hour

Since, change in wind speed and initial wind speed are constant

but the number of hours it took for the wind speed to reach its minimum for the day can be changed

so, most important variables is

the number of hours it took for the wind speed to reach its minimum for the day can be changed
