We will use the two points form, where
two points are given i.e (a,b) and (x,y)
then the slope of the line is given by
slope=y-b/x-a
For your question
slope =4-3/2-(-1)=1/3.
Answer:
The answer is C f(x)=(x – 5(x + 1)
Step-by-step explanation:
Answer:
Height of Tower = 41.8901 ft
Base to Ground Wire = 94.0905 ft
Step-by-step explanation:
So you want to find the opposing side of the angle, as well as the distance from the base to where the wire is attached to the ground. You would need to use CAH to find the ground, and SOH to find the height. To find the height or opposite, take the Sine of 24°, 0.4067, and times it by your hypoteneuse 103 to get an exact height of 41.8901 ft. Next, use the Cosine of 24°, 0.9135, and times that by your hypoteneuse 103 to get 94.0905 ft.
Here are the equations:
sin(24)=
cos(24)=

Answer: 8.2 (choice B)</h3>
==========================================================
Explanation:
First we'll need the length of segment BD, which I'll call x for now. The similar triangles allow us to set up the proportion below to solve for x
AD/BD = BD/DC
13/x = x/4
13*4 = x^2
52 = x^2
x^2 = 52
x = sqrt(52)
Segment BD is exactly sqrt(52) units long.
------------
Now focus your attention on triangle BDC. We'll use the pythagorean theorem to find BC
(BD)^2 + (DC)^2 = (BC)^2
( sqrt(52) )^2 + ( 4 )^2 = ( m )^2
52 + 16 = m^2
68 = m^2
m^2 = 68
m = sqrt(68)
m = 8.2462 approximately
m = 8.2
