Move point B to various locations on the circle, and measure the angles that are formed. Make a conjecture. What relationship ex

ists between the radius and tangent? The angles formed by the intersection of the radius and tangent are right angles. The angles formed by the intersection of the radius and tangent measure 90°. The tangent is perpendicular to the radius.

inysia [295]

Answer:

1/48

Step-by-step explanation:

1/4 of the cookies were Kim's

1/3 of that ( 1/3 x 1/4) were chocolate chips  which is 1/12 of the total

1/4 of that ( 1/12 x 1/4) had nuts . which is 1/48 of the total

The fraction is 1/48

If my answer is incorrect, pls correct me!

Which statement describes the function y = axn when a = 1 and n is odd?
kiruha [24]

Answer:

The graph is symmetric about the origin.

The graph does not pass through the origin.

Step-by-step explanation:

We're given:

  • the function y=axn
  • a = 1
  • n is odd

Because a = 1, then the given function can be rewritten as y = n.

  • The graph opens down

The function y = n will produce a horizontal line. Any function in the form of y = a single number, such as 4 or 9.3 will produce a horizontal line.

  • The graph is symmetric about the origin.

This is true, given the graph is a horizontal line.

  • The graph does not pass through the origin.

This is also true. We're given that n is an odd number. The graph will only pass through the origin if n = 0, and 0 is even.

  • The graph has more than one x-intercept.

This would only be true when n = 0, and this isn't possible. So, no.

Factor completely: 4a^2+b^2−c^2+4ab
Lapatulllka [165]

Answer:

4a^{2} + b^{2}  - c^{2}  + 4ab = (2a + b -c) (2a + b+c)

Step-by-step explanation:

Here, the given expression is 4a^{2} + b^{2}  - c^{2}  + 4ab

or, the given expression can be written as

 (4a^{2} + b^{2}  + 4ab ) - c^{2}

Now, by ALGEBRAIC IDENTITY: (x+y)^{2}  = x^{2} + y^{2}  + 2xy

So, similarly here, (2a +b){2}  = 4a^{2} + b^{2}  + 4ab

Hence, on simplification, the expression

(4a^{2} + b^{2}  + 4ab ) - c^{2} = (2a + b)^{2} - c^{2}

Now, by ALGEBRAIC IDENTITY: (x +y)(x-y) = x^{2}  - y^{2}

So, similarly  (2a + b)^{2} - c^{2}= (2a + b -c) (2a + b+c)

Hence, the given expression is factorized as:

4a^{2} + b^{2}  - c^{2}  + 4ab = (2a + b -c) (2a + b+c)
