A line has the equation y=1/3x-5 . Find the equation of a perpendicular line passing through (3, 2).

1 answer:

6 0

Slope of the line is ⅓. Slope of perpendicular to line is -3.
Point-slope equation for line of slope -3 that passes through (3,2):
y-2 = -3(x-3)

Use the information in the diagram to determine the height of the tree to the nearest foot.

algol13

Answer:

The correct option is A. The height of tree is 60 ft.

Step-by-step explanation:

From the given figure it is noticed that the building is creating a right angle triangle from a point and the tree divides the hypotenuse and base in two equal part.

According to midpoint theorem of triangle: In a triangle, if a line segment connecting the midpoints of two sides, then the line is parallel to third side. The length of line segment is half of the length of third side.

Using midpoint theorem of triangle, we can say that the length of tree is half of the building.

$Tree=\frac{1}{2}\times Building$

$Tree=\frac{1}{2}\times 120$

$Tree=60$

Therefore correct option is A. The height of tree is 60 ft.

Write three numbers greater than 20 that have 9 as a factor

Lubov Fominskaja [6]

We just need to find the multiples of 9 that are greater than 20.

9*1 = 9
9*2 = 18
9*3 = 27
9*4 = 36
9*5 = 45

We can use 27,36, 45, .....
Your final answer should be any multiple of nine greater than 20. I recommend using 27, 36, and 45. Hope this helps!<span />
