What is the value of r to the nearest tenth?

Tatiana [17]

Answer:

Hence r=10.3 cms (rounded to tenth place)

Step-by-step explanation:

In Triangle KLN ,

KN = 5 Cms

LN = ½ of LM

As the Perpendicular dropped from the center to the chord bisects it.

LM = 18 cm

LN = 9 cm

Now we have to find r or KL

We apply Hypotenuse Formula in this

The formula is given as

$c=\sqrt{a^2+b^2}$

Where c = r

a=5

b=9

Putting them in the formula

$r=\sqrt{5^2+9^2}$

$r=\sqrt{25+81}$

$r=\sqrt{106}$

$r=10.29$

Write the equation of the line given the graph. Enter your equation in y=mx+b without spaces.

love history [14]

The answer is y=-2/3+2 because the line crosses at 2, which is the y-intercept. It goes down two times and runs three times making the slope -2/3.
