<u><em>Answer:</em></u>
y^2 = 28x
<em><u>Step-by-step explanation:</u></em>
Since the directrix is horizontal, use the equation of a parabola that opens left or right.
(y−k)^2 = 4p(x−h)
Find the vertex.
(0,0)
Find the distance from the focus to the vertex.
p = 7
Substitute in the known values for the variables into the equation
(y−k)^2 = 4p(x−h).
(y−0)^2 = 4(7)(x−0)
Simplify.
<em>y^2 = 28x</em>
1.) c. x^2−2x+4−14/x+2
2.) The remainder is 1/2x-1. When you divide 8x^2+4x−3 by 2x-1, your answer is 4x+4 remainder 1/2x-1.
3.)The remainder is 6/(x+3) because when you divide 7x^2+15x−12 by x+3, you get 7x-6 remainder 6/x+3
The work is attached if you need it, sorry for the messiness!
Answer:
Its because the paper clips used here are of same length (4cm long).
So the measurements of lines two and three need to be multiples of 4 to me measured accurately with the paper.
i.e Line two needs to be 6cm + 2cm = 8cm (eight is a muliple of 4)
Line three needs to be 9cm + 3cm = 12cm (twelve is a multiple of 4)
Step-by-step explanation:
Since line 1 has 3 paper clips and its 12cm in length, the size of the paper clips is 4cm.
Line 2 is 6cm long and will require two more centimeters to measured accurately by the 4cm-paper clips.
Line 3 is 9cm and will require three more centimeters to be measured accurately by the 4cm-paper clips.
Answer:
Below.
Step-by-step explanation:
nth term = a1 r^(n-1)
= 8(-2)^(n-1)
When n = 16 it is
8*-2^15
= -262144.
