Vic is standing on the ground at a point directly south of the base of the CN Tower and can see the top when looking at an angle

mel-nik [20]

Vic and Dan are 2, 897m apart.

<h3>How to determine the distance</h3>

It is important to note that the distance between Vic and Dan is the base of CN

Let's say the distance to Dan is x

The distance to Vic is y

Using cosine ratio, we have

cos α = opposite / adjacent

α = 72°

opposite = 553. 3cm

Adjacent = x

cos 72° = $\frac{553. 3}{x}$

Cross multiply

$cos 72$ × $x$ = $553. 3$

$0. 3090x= 553. 3$

$x = \frac{553. 3}{0. 3090}$

$x = 1, 790. 61$ m

The distance to Vic is y

Using the cosine ratio, we have

$cos 60 = \frac{553. 3}{y}$

Cross multiply

$0. 5y = 553. 3$

$y = \frac{553. 3}{0. 5}$

$y = 1,106. 6$ m

To determine how far apart Vic and Dan, we use = x + y

= 1790. 61 + 1106. 6

= 2, 897. 21m

= 2, 897m

Thus, Vic and Dan are 2, 897m apart.

What is the slope of the line on the graph? Enter your answer in the box. A coordinate grid that includes the line y equals nega

RUDIKE [14]

we have

the equation of the line is $y=-2x$

the points are

$A(3,-6)\\B(0,0) \\C(-3,6)$

<u>Method 1</u>

we know that

A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form $y/x=k$ or $y=kx$

In this problem we have a direct variation

The constant of proportionality k is equal to the slope of the line

$k=-2$

$m=-2$

therefore

<u>the answer is</u>

the slope of the line is equal to

$m=-2$

<u>Method 2</u>

we know that

the formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have

$A(3,-6)\\B(0,0)$

substitute in the formula

$m=\frac{0+6}{0-3}$

$m=\frac{6}{-3}$

$m=-2$

therefore

<u>the answer is</u>

the slope of the line is equal to

$m=-2$
