Answer:

<h2>2.6</h2>

Step-by-step explanation:

To solve this, we need to use the Pythagorean theorem to solve this.

The way to solve is by solving for AD by using triangle CAD and then using that result to solve for BD.

3.4² + b² = 6.5²

11.56 + b² = 42.25

42.25 - 11.56 = b²

b = √30.69

b = 5.53985559 or about 5.5

4.9² + b² = 5.5²

24.01 + b² = 30.69

30.69 - 24.01 = 6.68

b = √6.68

b = 2.58456959666 or about 2.6

<h2>EDIT: the other user is incorrect, here's why</h2>

3.4 + 4.5 = 7.9

6.5² + 4.9² = 7.9²

66.26 doesn't equal 62.41

What is the equation of a horizontal line that has a y-intercept of 3.5?
beks73 [17]
First, recall that the equation of a line is

y = mx+b

where 

m = slope
b = y-int

The key to this question is the details :

Horizontal line ---> This tells you that your slope is 0

y-int = 3.5 -----> In the equation above, b=3.5

Therefore,

y = 0x + 3.5
y = 0 + 3.5
y = 3.5

What is the nth term rule of the linear sequence below 1,7,13,19,25
zysi [14]
First you see how it goes up 6 each time this is the start of your nth term rule
6n
Then -6 from the first term to get the ‘0th term’ 1-6=-5
So nth term rule is
6n-5
hope this helps

Suppose an ant walks counterclockwise on the unit circle from the point to the endpoint of the radius that forms an angle of rad
serg [7]

Answer:

\frac{4\pi}{3}

Step-by-step explanation:

The original questions is suppose an ant walks counterclockwise on a unit circle from the point (1,0) to the endpoint of the radius that forms an angle of 240 degrees with the positive horizontal axis.

To find the distance ant walked we find the arc length of the sector with central angle 240 degree and radius =1 (unit circle)

arc length of a sector =\frac{centralangle}{360} \cdot 2\pi r

arc length of a sector =\frac{240}{360} \cdot 2\pi(1)

arc length of a sector =\frac{2}{3} \cdot 2\pi

\frac{4\pi}{3}
