What is the equation of a line passes thru the point (4, 2) and is perpendicular to the line whose equation is y = ×/3 - 1 ??

cupoosta [38]

Answer:

Perpendicular lines have slopes that are opposite and reciprocal. Therefore, the line we are looking for has a -3 slope.

y= -3x+b

Now, we can substitute in the point given to find the intercept.

2= -3(4)+b

2= -12+b

b=14

Finally, put in everything we've found to finish the equation.

y= -3x+14

#17. The height, H metres, of a certain species of Fir

olya-2409 [2.1K]

Answer:

The approximated height of the tree is of 112 meters.

Step-by-step explanation:

The height of a tree with a base diameter of d meters is approximated by the following formula:

$h = 35d$

In this question:

Base diameter of 3.2m, so $d = 3.2$ , and the height is in meters.

$h = 35d = 35(3.2) = 112$

The approximated height of the tree is of 112 meters.
