Answer:5/48,3/16,0.5,0.75
Step-by-step explanation:
Use Pythagorean Theorem:
a² + b² = c²
"a" is one side of the right triangle.
Its length is: radius of larger circle minus radius of smaller circle: (11 - 3 = 8)
The distance between the center of the circles creates the hypotenuse (17)
8² + b² = 17²
b² = 225
b = 15
Answer: the length of the common external tangent is 15.
The answer is 7.
Look at the x=8 and then look up the y-value.
The graph passes (8,7) so therefore when x = 8 the y is 7
Answer:
r=4
Step-by-step explanation:
First you multiply 4 by r which gives you 4r. Then you multiply 4 by 2 to give you 8.So it looks like this now
4r+8-13=11
Now you add thirteen to both sides and get
4r+8= 24
Then you subtract both sides by 8 to get 16
4r=16
Then you divide both sides by 4 to get 4
r=4
