Answer:

[tex]option \: 1. \: is \: correct.[/tex]

Step-by-step explanation:

[tex]9 {}^{ \frac{1}{3} } = \sqrt[3]{9 {}^{1} } \\ but \: for \: 9 {}^{ \frac{1}{3} } \: to \: equal \: 9 \: \\ then \: it \: should \: be : {(9 {}^{ \frac{1}{3} } )}^{3} \\ therefore \: the \: option \: 1. \: is \: correct.[/tex]

Answer:

1.)c=±√58

Step-by-step explanation:

According to Pythagorean theorem, square of the hypotenuse is equal to the sum of the squares of other two sides

a^2+b^2=c^2

Short sides-a and b

Long side=c

I will do number 1 for you as an example.

A=3

B=7

C=x

3^2+7^2=c^2

58=c^2

Dont forget to square 58

c=±√58

Answer:

I'm guessing point C is (-6,-5)? But then, it would have to be the coordinates you listed, (-3,-5) and (-9,-5) because nothing else makes sense.

Or is it one of those questions that you give your own coordinates? I'm confused :'(

Answer:

M²

Step-by-step explanation:

Parallel lines have equal slopes.

One line has a slope of M then the line parallel to it has a slope of M , thus

product of slopes = M × M = M²

The the product of their slopes is M².

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx

where, m is the slope

Given:

two lines are parallel

and the slope of one of the lines is M

Also, the parallel lines have the same slope.

So, both the line lines have slope M.

Now, the the product of their slopes

= M x M

= M²

Hence, the product of their slopes is M².

Step-by-step explanation:

Let as consider, we need to find the number of hours h it will take Mandy to catch up with Rita.

Given:

The number of hours h it will take Mandy to catch up with Rita is represented by the equation

[tex]2.5h+1=3h+2[/tex]

To find:

The value of h.

Solution:

We have,

[tex]2.5h+1=3h+2[/tex]

Isolate the variable terms on one side.

[tex]2.5h-3h=-1+2[/tex]

[tex]-0.5h=1[/tex]

Divide both sides by -0.5.

[tex]h=\dfrac{1}{-0.5}[/tex]

[tex]h=-2[/tex]

We know that, time cannot be negative. So, [tex]h\neq -2[/tex].

The equation [tex]2.5h+1=3h+2[/tex] is not true for any positive value of h.

Therefore, Mandy will never catch up with Rita.
