In the diagram below, the measure of angle XAY is 72° (m∠XAY = 72°). Since the measure of the intercepted arc XY is 144°, a student named Naomi mistakenly claims that the measure of ∠XBY is also 144°.a. In a short paragraph, explain the source of Naomi’s error. In your response, be sure to describe the problem in terms of the following two formulas:

inscribed angle = 1/2 · (intercepted arc) and
intercepted arc = central angle.

Be sure to use important vocabulary like “inscribed angle,” “central angle”, and “intercepted arc”.

Answers

Answer 1

Answer:

Angle of the intercepted arc is equal to the angle at the centre (central angle) but B is not the centre hence XBY is not 144°.

Angle at the circumference (inscribed angle) is half of the central angle, but XBY is not the central angle, so it's not 2×72.

Hence not 144°

How would u solve this equation 7 4x-9=-6

Answers

Depending on your question...

7(4x) - 9 = -6
28x -9 = -6
28x = 3
x = 3/28

OR

7 + 4x - 9 = -6
4x - 2 = -6
4x = -4
x = -1

Hope that helps :)

There are multiple different ways to solve the question because we don't know what is between 7 and 4.

7 + 4x - 9 = -6
Subtract 7 on both sides.
4x - 9 = -13
Add 9 on both sides.
4x = -4
Divide by 4 on both sides.
x = -1

or

7 - 4x - 9 = -6
Add 9 on both sides.
7 - 4x = 3
Add 4x on both sides.
7 = 4x +3
Subtract 3 on both sides.
4 = 4x
Divide by 4 on both sides.
x = 4

What is the degree of the monomial 7x^8

Answers

The given monomial is

$7x^8$

And degree is the highest exponent of the constant .

For e.g.

Degree of $x^5$ is 5 since 5 is the exponent of x here. And in the given question, Here the constant is x.

And the exponent of x is 8 .

Therefore the degree of the given monominal is 8 .

it is to the power of 8

What is 64x6 + 27 written as a sum of cubes?(4x)3 + 33
(4x2)3 + 33
(4x2)3 + 93
(4x3)3 + 33

Answers

To transform the given expression to sum of cubes, calculate first the cube root of the terms. The cube root of the first term, 64x^6 is 4x^2 and that of the second term, 27 is 3.

Thus, the answer to this item is the second choice, (4x^2)^3 + 3^3
