If PR=40, what are PQ and RQ

Mathematics

AleksAgata [21]4 years ago

PR = PQ + QR = 40

Substitute PR and QR into the equation above

40 = 5x - 2 + x + 12

Combine like terms

40 = 6x + 10

Subtract 10 from both sides

30 = 6x

Divide both sides by 6

5 = x

PQ = 5x - 2= 5(5) - 2 = 23

Remember, PR = PQ + QR

40 = 23 + QR

Subtract 23 from both sides.

17 = QR

PQ = 23

Write the standard form of the equation of the parabola with the given focus or directrix and
horsena [70]

Answer:

x = 1/20 y^2

Step-by-step explanation:

This is a rightward opening  (sideways ) parabola

Directrix = x = -5

Distance formula form point x,y  to directrix and focus are equal:  

(x - -5)^2 = (x-5)^2 + y^2

x^2 + 10x + 25 = x^2 - 10x  + 25 + y^2

20x = y^2

x = 1/20 y^2

If it is asking if that equation is the quadratic formula, then the answer is false. The reason why is that the first 'b' should be negative

The quadratic formula is

x = \frac{-b \pm \sqrt{b^2-4ac}}{2a}
