Can anyone tell me the standard form of this parabola equation?

irina [24]

Answer:

$x=4y^2-24y+30$

$(x-4.5)^2+(y-2.5)^2=23$

Step-by-step explanation:

Standard form of a sideways parabola: $x=ay^2+by+c$

Given equation:

$4y^2-x-24y+30=0$

Add x to both sides:

$4y^2-24y+30=x$

$\implies x=4y^2-24y+30$

--------------------------------------------------------------------------------------------

<u>Standard form of circle equation</u>

$(x-a)^2+(y-b)^2=r^2$

(where (a,b) is the center and r is the radius)

Given equation:

$2x^2+2y^2-18x-10y+7=0$

Group like terms:

$2x^2-18x+2y^2-10y+7=0$

Divide by 2:

$x^2-9x+y^2-5y+3.5=0$

Factor by completing the square for each variable:

$(x-4.5)^2-20.25+(y-2.5)^2-6.25+3.5=0$

Rearrange into standard form:

$(x-4.5)^2+(y-2.5)^2=23$

Therefore, the circle has a center at (4.5, 2.5) and a radius of √23

8 less than the product of 5 and-4

alina1380 [7]

So it says 8 less than, meaning 8 minus the product of 5 and -4, so literally it means subtract 8 from 5X-4
8-5*-4

Consider the function f(x) = 9^x. Which statement MUST be true? A) f(4)/f(1) = f(8)/f(5) B) f(4)·f(1) = f(8)·f(5) C) f(4) − f(1)

shtirl [24]

Step-by-step explanation:

the true answer is (A)

the right side : 9^4 / 9^1 = 9^3

the left side : 9^8 / 9^5 = 9^3

two side are equal
