Answer:

$7$

Step-by-step explanation:

So we have the expression:

$|3x-1|$

And we want to evaluate it for x=-2.

So, substitute -2 for x:

$|3(-2)-1|$

Multiply:

$=|-6-1|$

Subtract:

$=|-7|$

The absolute value of a negative is positive. So:

$=7$

And we're done!

a woman 1.65. tall stood 50m away from the foot of a tower,and observe that the angle of elevation of the top of the tower to be

ElenaW [278]

$\sf\huge\underline{\star Solution:-}$

$\rightarrow$ Let the women's height be AE and distance between the women and tower be AC.

Also let the height of tower be BC.

$\rightarrow$ Now, clearly it is forming a triangle.

So, in triangle ABC,

$\rightarrow$ $\sf{Tan50° \:= \: \frac{BC}{AC}}$

$\rightarrow$ $\sf{1.19 \:= \: \frac{BC}{50}}$

$\rightarrow$ $\sf{1.19 ×50\:= \: BC}$

$\rightarrow$ $\sf{59.5m\:= \: BC}$

$\rightarrow$ Hence, BC = 59.5m

So, BD(total height of the tower) $\sf{ = \:BC+CD}$

$\sf{= \:59.5+1.65}$

$\sf{=\: 61.15m}$

Therefore, total height of the tower = $\sf\purple{ 61.15m.}$

Ive labeled the ordered pairs but what does it mean by state the quadrant or axis in/on which the point is located

irina1246 [14]

So the image below shows what quadrants are. From the top-right square, the order of quadrants goes from 1-4 in a counter-clockwise matter.

Quadrant I: Top-right square

Quadrant II: Top-left square

Quadrant III: Bottom-left square

Quadrant IV: Bottom-right square.

Any points that are on the bolded vertical line are on the y-axis, and any points on the bolded horizontal line is on the x-axis.
