Answer:
? = 9.2
Step-by-step explanation:
The angle between a tangent and radius at the point of contact is 90°
Then the triangle shown is right with legs ? , 6.9 and hypotenuse = (6.9 + 4.2) = 11.5
Using Pythagoras' identity in the right triangle
?² + 6.9² = 11.5²
?² + 47.61 = 132.25 ( subtract 47.61 from both sides )
?² = 84.64 ( take the square root of both sides )
? = = 9.2

We want to find the value of:
One of the rules of Indices, called the Power with Exponent Zero rule, states that any number raised to the power of zero is equal to 1.
This means that:
That is the answer.
Answer:
The degree of the polynomial is 3
Step-by-step explanation:
Given:
To Find:
The degree of the polynomial= ?
Solution:
The degree of the polynomial is the value of the greatest exponent of any expression (except the constant ) in the polynomial. To find the degree all that you have to do is find the largest exponent in the polynomial
Here in the given polynomial
The terms are
The term has the largest exponent of 3
Note: The degree of the polynomial does not depend on coefficients of the terms
