Answer:

always negative

Step-by-step explanation:

That is, if you exclude 0. If you count zero as a positive number, that will be the exception to the rule. Luckily, zero is usually considered neither negative or positive.

Answer:

13. c,

14. a.

Step-by-step explanation:

13. The length of a side PQ with coordinates of

P as (x,y) and Q as (w,z)

is: $\sqrt{(x-w)^{2} +(y-z)^{2} }$

so, the length of the side AB =

$\sqrt{(5-5)^{2}+(-2+7)^{2} } =\sqrt{0^{2}+5^{2} } =5$

the length of side BC =

$\sqrt{(5-1)^{2}+(-7+2)^{2} } =\sqrt{(4)^{2}+(-5)^{2} } =\sqrt{4^{2}+5^{2} }$

the length of side AC=

$\sqrt{(5-1)^{2} +(-2+2)^{2} } =\sqrt{4^{2} } =4$

now, the easiest one will be when the vertices are on the coordinate axes.

so, option c will be the most appropriate one.

14. If u see the figure clearly, the lines l and FH are parallel.

the parallel postulate, i.e, the alternate interior angles will always be congruent.

here, the alternate interior angles are angle1 and angle4.

therefore to prove this step, he used parallel postulate as a reason.

so, the correct option is "a"

Help Pls! It's for my Math 4! Scalar Multiplication!

prohojiy [21]

Answer:

Concept: Physics Qualitative Analysis.

Scalar values are constant and compared to vector values they do not have a direction or magnitude or a gradient representation.

Lets get started by setting up the equation
They want us to find 3U-2V
Given U= <6,6> V=<6,-6>
Now we plug in and solve!
3<6,6>- 2<6,-6>
<18,18>-<12,-12>
Subtract
<18-12,18-(-12)>
Hence that gives us a result of <6,30>
Now with the skills you gained solve the rest!!!

It is 50 thousands because 5 times 10 = 50.
