Answer:

20%

Step-by-step explanation:

Well if there's 5 answers for the question, and he answered two questions. That means the two questions together have 10 answers.

He chose one answer for each question, that is 2/10 or 1/5 or 20%

professor190 [17]

Answer:

120i

Step-by-step explanation:

;i × i = -1....so hence

4i × (-5i) = -20 i^2...which is -20(-1) = 20....

then you multiply with 6i

20(6i) = 120i

HELP!!!!!!!!! ASP
Anarel [89]

Answer:

D

Step-by-step explanation:

What you need to do is find the slope of both lines. Perpendicular lines are the negative inverse of each other. The slope of the lie between points R and F is  (2-4)/(1+9)=-1/5. Now you need to find the line where the slop is 5. If you look at D, the slope of the line those points lie on is (25-15)/(4-2)=5 which makes D the answer.

T he equation for a parabola with directrix y = –p and focus (0, p) is:
zhuklara [117]

The equation for a parabola with directrix y = –p and focus (0, p)

The distance between vertex and directrix is P

Also the distance between vertex and focus is also P

Focus (0,p) so focus lies on y axis

Directrix line is paralled to focus point

So Directex crosses the x axis .

Hence line of symmetry lies is the y-axis.

The graph is attached below.
