WILL GIVE BRAINLIEST AND THANKS. determine if these are tangent to the circle

Mathematics
1 answer:
BARSIC [14]3 years ago
8 0

Answer:

19 Five is not tangent to the circle.

20 Eight is tangent to the circle.

Step-by-step explanation:

In order for one of the legs to be a tangent to a circle, the length must be part of a right angle triple.

I don't think the diagram on the left is, but I'll check it.

5^2 + 12^2 =

25 + 144 =

169

square root of 169 is 13

The length of the hypotenuse should be 13 not 14. Fourteen does not make Pythagorean triple. 13 would. So the line 5  units long does not make a tangent to the given circle.

The diagram on the right is a different story. 6 8 and 10 do make a Pythagorean triple, even though the two diagrams are not the same.

The radius and the distance to the external point  form a right angle.

The Pythagorean triple is

6^2 + 8^2 = 10^2

36 + 64 = 100  

100 = 100

How do you convert 250% into a fraction
Ann [662]
Hello there.

Question: <span>How do you convert 250% into a fraction.

Answer: </span>Step 1: Factor both the numerator and denominator down to prime factors:
250 = 2 * 53 
100 = 22 * 52
Step 2: Calculate the greatest common factor, GCF 
GCF = (2 * 53; 22 * 52) = 2 * 52 
Step 3: Divide both the numerator and denominator by their greatest common factor, 250/100 =
(2 * 53)/(22 * 52) = 
<span>((2 * 53) : (2 * 52))</span> / <span>((22 * 52) : (2 * 52))</span> =
5/2
Ways of writing this:

<span>Positive improper fraction: 
250/100 = 5/2 

Mixed number (also called mixed fraction): 
250/100 = 2 1/2 

Decimal number: 
250/100 = 2.5

In short, Your answer is<span> 5/2</span>.

Hope This Helps You!
<span>Good Luck Studying ^-^</span></span>

Limit b⇒0 (Sin b)/b³
Nitella [24]

Answer:

infinity

Step-by-step explanation:

Given the function

Limit b⇒0 (Sin b)/b³

First substitute the value of b into the function to have

Limit b⇒0 (Sin b)/b³

= sin 0/0³

= 0/0 (Ind)

Apply lhospital rule

Limit b⇒0 (d./db(Sin b))/(d/db(b³))

=>Limit b⇒0 (cos b)/3b²

Substitute the value of b

Cos 0/3(0)²

= 1/0

= infinity

Hence the answer is infinity
