Answer:

Step-by-step explanation:

Pick a letter that's easy to count. I chose Q, because it has a tail below the baseline that makes them easy to spot.

Not C or D — too many quarters

Not B — too many nickels

It is often easier to find the correct answer choice by eliminating the bad choices, then seeing if what is left is consistent with the problem statement.

Choice A seems to have the right numbers of pennies and dimes (along with quarters and nickels).

How to identify the parent function given an equation ?

Anettt [7]

Answer:

You can identify the parent function by making the equation into its simplest form.

Step-by-step explanation:

Remove all transformations from the equation (such as plus/minus signs, constants, and extra terms in the equation).

ex. y= -3x^2+15

The parent function would be y=x^2 after removing everything.

Hope this helps! :)

Answer:

Step-by-step explanation:

The person I sent it to couldn't see it either. I'm going to take a chance and say the Chord (AB) and the Tangent line form a 50 degree angle. If this is incorrect, I won't know, from the diagram, what else to try.

If I'm right then <OAB = 40 degrees because 90 - 50 = 40 because <AOC is a right angle (property of radii and tangents).

<ABO also = 40 (the triangle is isosceles by two legs being radii).

That means that BOA = 180 - 40 - 40 = 100
