a parabola has a vertex at the orgin.The focus of the parabola is located at (-2,0).Which is the equation for the directrix rela

The focus is left of the vertex, so the parabola opens to the left. The vertex is halfway between the focus and directrix, so the directrix is the vertical line

Line AC is tangent to circle O at point C<br> What is the measure of OAC?
Nuetrik [128]
AC is a tangent so by definition, it touches the circle at exactly one point (point C) and forms a right angle at the tangency point. So angle ACO is 90 degrees

The remaining angle OAC must be 45 degrees because we need to have all three angles add to 180
45+45+90 = 90+90 = 180

Alternatively you can solve algebraically like so
(angle OAC) + (angle OCA) + (angle COA) = 180
(angle OAC) + (90 degrees) + (45 degrees) = 180
(angle OAC) + 90+45 = 180
(angle OAC) + 135 = 180
(angle OAC) + 135 - 135 = 180 - 135
angle OAC = 45 degrees

Side Note: Triangle OCA is an isosceles right triangle. It is of the template 45-45-90.

Clara brought 24 donuts for the office. If 6 of them were chocolate, what percent of the donuts were chocolate
mafiozo [28]
To find the percent, you have to divide 24/6 
24/6 = 0.25
Now you convert 0.25 to a percent. 
So move the decimal point 2 places to the right. 
= 25 %

alexandr1967 [171]

<em>Answer:</em>

<em>D)</em>

<em>Step-by-step explanation:</em>

<em>We know that it cannot be C since z is not involved in this problem.</em>

<em>a) 3/20x</em>

<em>Try with 20 = x</em>

<em>3/440 ≠ 3</em>

<em>A is not the answer.</em>

<em>b) 60x</em>

<em>Try with 20 = x</em>

<em>1800 ≠ 3</em>

<em>B is not the answer.</em>

<em>c) 60/x</em>

<em>Try with 20 = x</em>

<em>3 = 3</em>

<em>Try with 15 = x</em>

<em>4 = 4</em>

<em>D is your answer.</em>

<em>Hope this helps. Have a nice day. Oh, and one more thing. Surprised to see I'm not stealing points?</em>
