(w^5 z^2 )(−9w^2 z^5)

1 answer:

5 0

We have that
(w^5*z^2)*(-9*w^2*z^5)

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

What is a turning point on a quadratic graph?

Cerrena [4.2K]

Answer:

A turning point is the highest or lowest point on a quadratic graph.

Step-by-step explanation:

A quadratic graph looks something like the graph below.

The equation of a quadratic graph would normally look like

+/- ax^2 + bx + c

An example might be -16x^2 + 5x + 4

Note the negative symbol in front of the 16. The negative means that the graph will be facing downwards, or that the turning point is the highest point. A positive graph will mean that the graph is facing upwards, or that the turning point is the lowest point.

Essentially, it is the location where a graph has its lowest or highest point and where the y-values (can include x-values in horizontal quadratics) "turn" to the direction they originated.

MAVERICK [17]

Complete question :

Mavis is interested in whether military dependency is related to gender in American Samoa. Here is data she collected about the population of American Samoa in 2010.

Millitary status _________ female ____ Male

In armed forces _________ 28 _______ 59

Millitary dependent ______ 928 ______ 781

Civilian _______________ 26393 ___27330

Answer:

Male = 0.4193

Female = 0.5087

Step-by-step explanation:

To obtain the marginal distribution of gender :

Total number of civilians (male + female)

(26393 + 27330) = 53,723

Male :

P(male) = number of male / total

P(male) = 26393 / 53,723 = 0.4912793

P(Female) = number of Female / total

P(Female) = 27330 / 53,723 = 0.5087206

Vlad1618 [11]

One person has

$3.2x10^{-5}\text{ lbs of zinc}$

then, in the body of 3500 such people, there are

$3500\cdot3.2x10^{-5}\text{ lbs of zinc}$

this product is equal to

$3500\cdot(0.000032)=0.112\text{ lbs}$

of zinc
