Answer:
17. 5
18. 17
Step-by-step explanation:
The distance formula is used for the purpose.
d = √((x2 -x1)² +(y2 -y1)²)
__
17. d = √((3-6)² +(1-5)²) = √((-3)² +(-4)²) = √(9+16) = √25 = 5
The distance between the points is 5 units.
__
18. d = √((-1-7)² +(12-(-3))²) = √(64 +225) = √289 = 17
The distance between the points is 17 units.
Answer:
The correct option is;
10 m
Step-by-step explanation:
The parameters given are;
Height of the first pole = 20 m
Height of the second pole = 14 m
The angle the wire connected to their top makes with the horizontal = 30°
The vertical height subtended by the inclined wire, h = The difference in height between the two poles = 20 - 14 = 6 m.
Let the horizontal distance between the two poles = D
Therefore;
The horizontal length of the wire = D
From trigonometric ratios, we have;

Which gives;

The correct option is 10 m.
The answer should be either b or d but i’m not too sure
Answer:
there is no options but anything that doesnt equal 1/2 esstentially because 4/8 is the same as 1/2
Answer:
slope of line is 3
y-intercept of line is -13
Explanation:
The general formula of the linear line is:
y = mx + c
where:
m is the slope of the line
c is the y-intercept
The given line is:
y = 3x - 13
Comparing the given line with the general formula, we would find that:
m (the slope of the line) is 3
c (the y-intercept) is -13
Hope this helps :)
